    • Lots of bad design decisions
Style: 100-Volt, 20 Amp
The media could not be loaded. The video is an example of the connection issues Victron has on android and we also see one of its buggy behaviors — wild fluctuations, you cannot leave this controller alone, you have to babysit it due to the bugs. Feb. 21, 2021 Pros Small hardware footprint Mobile app for Android & iOS A wide range adjustable settings via the app Tail current setting Cons No temperature port No voltage port Faux temperature compensation Rather useless load output Bluetooth connection issues on Android Tail current setting buggy Doesn't deal with clouds well Manual equalization limited to 1 hour Erratic behavior at times = buggy "Designed in the Netherlands, Made in India" Technical support Installation Installed in a Class B RV, ~5' of 4/00 awg wire from battery to buss, 2' of 12 awg wire from battery buss to controller — voltage drop according to my volt meter is 0.01v which the controller matches, eg 12.81v at battery terminals reads 12.80v by controller. Two 100 watt Rich Solar portable solar panels connected, in series, to the charge controller — depending on the distance from the vehicle required to get good sun they can be connected via 45' of 6 awg cable or 12 awg for shorter distances. During this review period they were connected via the 5' of wire on the panels to ~8' of 12 awg wire to the controller. voltage drop was negligible. All in all, thanks to the small size, the Victron was easy to install however, as others have pointed out, the terminals are too small. Heavy gauge wire should be used from battery to charge controller but Victron terminals are 10 awg, so they cause the user problems here which will lead to voltage drop = stupid design choice. Note: Victron Smart Battery Sense was installed, for a period, though it read 0.04v higher than my volt meter — see my review on it, 1 star. Battery requirements Absorption voltage: 15.8v + temp comp Equalization voltage: 16.3v + temp comp for 2 hours Temperature compensation 0.0028v/cell/°F Two ~96Ah batteries These battery requirements are for 12 volt Interstate Marine/RV 27DC batteries purchased at Costco — I didn't know they were Calcium-Calcium batteries at the time, didn't know what I was doing really. 🤷♂️ But to be fair to Interstate they have done rather well considering they've been consistently undercharged for two years. Nonetheless, each battery manufacture has specific requirements for charging, and what I've found with solar charge controllers is, most can't or don't have the ability to match the manufacturer's requirements. Many limit maximum voltage to 15v and have no ability to set time frames for absorption or equalization. In other words, a charge controller that dictates a 14.8v charge and 15v equalization isn't a charger that can get the battery fully charged or equalize it in many instances — check your manufacturer's charging requirements before purchasing a charger, and then read the charge controller's user manual before purchasing, you'll be surprised how many can't meet the necessary requirements yet have 5 start rave reviews. This was my problem with my OEM charge converter — its maximum voltage is around 14.4v thus I would have to be plugged into shore power for a week to get a full charge = not good for boondocking. Monitoring device — a spare Moto e4. Firmware v1.54 Bluetooth interface Rev2 Firmware v2.25 Bootloader v1.11 Android app 5.35 Hardware The hardware is very small, ~4"x4" which makes it good to hide in a small RV. The 100/20 has good sized heat displacement aluminum fins and through my tests pushing it at about 190 watts continuously it warmed to ~93°F with interior temps in the low 70°F. The MPPT function seems to work reasonably — it has extracted 196 watts out of the 2x100 watt Rich Solar panels consistently without them being perfectly aligned, I might add — this is in the arizona desert, February, ~1,700ft elevation. The wire terminals are too small and there is no port for temperature or voltage sensors — at this price point this is a major design flaw and a real finger in they eye of their customers — Victron's solution is a Bluetooth battery sensor that is a buggy overpriced peace of garbage that they don't fully rely on for voltage which tells you all you need to know. Victron claims to have temperature compensation but with no wired temperature sensor how do they do it? Wel...it's a fake temperature compensation. Victron uses the internal temperature sensor of the controller at the beginning of charging to adjust the voltage. Note that it doesn't adjust the voltage throughout the charging period based on this sensor's temperature, as it can't because this sensor is reading the internal heat of the controller and it would be drastically off once it does any real work that causes the controller to get warm. Therefore this gives the user a false sense of security, as Victron isn't clear about what is really going on. If you have a long charge cycle and are in an area, like arizona, that have +30°F temperature swings from morning to noon you could very well cook your batteries as the controller will set the voltage based on 40°F in the morning and keep that temp correction the entire day, therefore as your batteries warm from being charged at a higher voltage and the ambient temperature warms them the voltage isn't being decreased appropriately as it would be if it had real temperature compensation — you need to add a $40 bluetooth device for that, which will introduce more problems. 🤦♂️ No voltage sensor and small wire terminals — it's as though Victron wants their users to have their charge controller's voltage off as much as possible. 🤷♂️ Load output — there's some conflicting information on the internet about this. Some say, go ahead and wire whatever you like as long as it's not pulling over the rated capacity, others say don't wire in anything that has a high starting current. So I contacted Victron about running an absorption fridge that pulls 10 amps — not a good idea to wire in such things, better to get a bmv battery protect.... And to please direct my questions to local dealer lol 🤦♂️ Software The biggest problem I have with their software is that Victron blocks access to the charge controller until firmware update is complete. My initial attempts at updating the firmware via a Moto e4 failed on the final update, numerous times, rendering the controller useless as access was blocked until the mandatory update was done. Luckily my Samsung Galaxy Tab A 10.1 worked. IMO this is an absolutely horrible software design — there should always be a graceful fallback in case of failures, leaving the hardware useable not blocked. What's Victron's solution for people that find themselves in such a solution? Use an iPhone! Seriously, right in their manual, I kid you not — so I need to buy a $500+ phone??? Because they can't properly program for the largest platform on the planet? Apparently Victron software engineers are so closed minded that they can't comprehend that there are times when things don't work as expected and the user doesn't have multiple devices of differing operating systems to try, especially considering people will use these in RVs and be in the middle of nowhere. 🤦♂️ Bluetooth connection issues The Bluetooth connection was horrible with the Moto e4 but decent on the Tab however the last update greatly improved the range for the Moto e4. Nonetheless there are still many times when you have to disable bluetooth to clear the device cause it won't connect. All in all its not a good bluetooth performer on Android. This was greatly exacerbated when I added the Bluetooth Smart Battery Sense. Furthermore, any time you lose focus on the app the app has to reconnect. Apparently Victron doesn't understand that on Android apps can run in the background and stay connected when not in focus — clearly they are overly focused on iOS development. This creates a rather poor user experience on Android, all in all. One reviewer stated that the Bluetooth low energy that Victron utilizes wouldn't work with older devices, well my phone and tablet are older and they are fine.... Well, mostly. Generally BLE is available to Android 5 and new, but it's still something you need to check to see if your phone or tablet has it, as not all manufacturers utilize it. Tail current This is a great feature — set a current, amps, point that when charging falls below it will go into float mode. The problem is, it doesn't work if there are clouds. This has been discussed on Victron forums and their "fix" didn't fix anything. What happens is, a cloud drops the inbound power below the tail current which triggers the tail current setting dropping you out of absorption mode into float = partial charge of battery. I witnessed this multiple times on a cloudy day, along with other strange behaviors such as my panels producing 35% more power than their maximum, and the app displaying 0 current yet voltage holding at absorption voltage levels. In other words, Victron doesn't know how to deal with cloudy weather. The simple solution is, compare inbound power to the tail current whenever it is triggered — if inbound power is greater than power to battery then trigger tail current function, if inbound power is less than power to battery ignore tail current. In other words, the tail current function should only be triggered if and when the inbound power is greater than the outbound. So, in cloudy weather you need to disable the tail current setting or babysit the charge controller because Victron can't figure this simple problem out. But, at least they have a tail current setting which most other charge controllers don't. Another bizarre software design choice is, Victron limits manual equalization to one hour — apparently I didn't know what I was doing when I set the equalization time to two hours, Victron clearly knows better than I or the battery manufacturer. Seriously? 🤦♂️ Why on earth can't manual equalization just run the settings I've set? Why? Finally, and this is only the Android app as I don't use a PC any more and don't own Apple devices, there are times when the app is just buggy, slow to respond, freezes, etc. Victron has lots of work to be done on the Android app. However, the mobile app, for me, is Victron's saving grace. First, many other charge controller manufacturers don't even have an Android app and those few that do are often limited in capability. Victron allows the user a full range of settings to customize — voltage up to 17.39v, duration for absorption and equalization up to 24hrs, manual equalization, set auto equalization days, etc. You can download the app and setup a demo product to see all the possible settings. It's a good start and ahead of the competitors, but still has some kinks to work out. For someone like myself, in a small RV who uses only mobile devices Victron takes the lead here. Tech support Victron is heavily reliant on the, in my opinion, old and outdated dealer model. Victron doesn't want to hear from customers, period. Go through your dealer. This isn't the wisest mentality in a time where everything is via online. Nonetheless, that's the model they are using. Therefore you may want to check who's selling you a Victron product and what their support is like..... Good luck with that. Furthermore I wasn't happy to see on the box, "Designed in the Netherlands, Made in India." I was hoping to get a quality built product from the Netherlands but Victron is like most every other company these days — sourcing the cheapest parts and labor, slapping on a high makeup by touting they are a company in the Netherlands. No, their products are like most others, built by the cheapest labor on the planet using the cheapest parts — no wonder they seem to like Apple so much. All in all I am deeply disappointed with the entire solar charge controller market. We live in a day that smartphones are ubiquitous and inexpensive, yet most charge controller manufacturers have either no mobile software compatibility or terrible software with unnecessarily limited settings. It really boggles the mind! Obviously, like so many things made today, these devices are being engineered by people that have never, and probably will never, use them in the real world therefore they are clueless as to the real needs of users. Victron does better in some areas but then does a total face plant in other areas...... Really unbelievable IMO. There are two charge controller manufacturers, other than Victron, that have decent adjustability in their software that I've seen. They are Epever and Morningstar. Morningstar uses PC software only. Epever has an Android app, it's ok, not great, but I received a defective unit from them and their hardware footprint is rather large Renogy, from the manuals I looked at, are another manufacturer that doesn't let you have much flexibility in the software, but that may be only the ones I looked at. For me, since I've got a rather manual setup to begin with — portable solar panels and all — I can, with the Victron, at least utilize it rather easily and use it in a manual nature — it's not a controller I would "leave it and forget it" to do it's thing, to buggy at this point in time. Hopefully the solar charger controller market starts to mature quickly. ... show more

    • A better solar charger.
Style: 75 Volts, 15 Amp
Review Image by Sourdo Sourdo
Review Image by Sourdo Sourdo
I recently installed two 100 watt Renogy solar panels on top of my RV trailer, along with a Renogy 30 amp PWM controller with a bluetooth dongle. The panels work fine, the Renogy SCC (Solar Charge Controller) not so fine. The bluetooth app is broken, crashes frequently, and is mostly a waste of money. While the Renogy SCC did it's job, the performance on cloudy/shaded days was inadequate. With a PWM SCC, you must run your panels in parallel. You cannot fully charge a battery with 13 volts available (cloudy day in trees) from the PWM SCC, no matter what the amps is. With the panels in series, that 13 volts would now be 26 volts. So I ordered the Victron SmartSolar 75/15 MPPT controller with built in Bluetooth. With an MPPT controller, you have the option to run your panels in series or parallel. Running my panels in series doubles available voltage (up to around 40 volts, which the SCC converts excess voltage to the appropriate voltage (12 or 24 volts) and current (amps) to charge your batteries. This SCC handles this nicely. The unit was delivered in brand new condition. I was surprised how small it is. There are three LED indicator lights on the front. You cannot flush mount this device. I installed this inside a wall with a vent pipe, and ran my wires out the top of the RV via the vent exit. Where I mounted inside the wall, I used a tin lid against the wood. The instructions say to mount the unit on a non-combustible surface. I stacked two washers between the wall and tin, offering a better way to dissipate heat from the back of the device. If you look closely at the picture, you can see what I did. Then I made a facade cover with a small "peep hole" to quick view the LED's. These LED's are quite bright, some people tape over them. I would try a black felt tip marker to try and dim things first. There is no way to flush mount this unit. You cannot use wire bigger than 10 AWG. Some claim 10 AWG is too big, but that just isn't so. Just don't mangle the wire ends and they'll fit. But there is a better way, read below. What I do is to "tin" the wire ends. Strip off 1/2 inch of wire, give a slight twist to keep the strands tight. With a good soldering iron, solder the wire end, making sure the solder flows evenly. Not too much or you'll end up with a "fat" end that won't fit in the lugs. You might practice this with a piece of wire, but once done correctly you have a superior connection. Then after inserting the end into the lug, tighten snuggly, then loosen, the re-tighten. Each time the lug will screw down a little tighter as the lug "worms" into the wire end. I'll do this at least 10-15 times, until the lug is snug and secure. Be careful to not over tighten and strip the lug. Use cable restraints. Once the battery is connected, hook up the PV array. I cover my solar panels with some plywood (or some cardboard) to turn down the open voltages while I connected those, which for two 100 watt panels in series is over 40 volts in bright sun and could shock you. I also installed a disconnect switch for the PV panels, next to that is the inverter remote switch. Your battery must be connected first, then connect the PV array. The one weak area of this device is the manual. It comes with a tiny booklet that is difficult to read. You can download the PDF version from Victron's website. Some of the info is sketchy and in not so plain English. For some info you need to install another app called Victron Toolkit. This offers explanations of the various blinking LED functions. The built in Bluetooth requires an app called Victron Connect(I have an Android Nokia smartphone) for reading power outputs, managing battery charging profiles, etc. The app was downloaded and installed without issue. With the app installed and paired to my phone, the app quickly upgraded the firmware for the SCC. Once this was done, the app works very well. I can walk about 40 feet away and can still stay connected, which is about normal for Bluetooth devices. Again, the app is well done and works well. The manual has some odd English to explain some of the functions. I'll try to explain in "plain English" as I see it. When you first hook up the SCC, the manual says 5+ volts from the PV panels over the Battery volts is needed to be "operational" (According to the manual). I would expect the unit to be "operational" when I bought it brand new out of the box. What this really means is this; "When the controller sees 5 or more volts from the PV (solar panels) above the battery volts, it turns on the charger. When the PV volts drops to 1 volt or less then the battery volts, it turns off the charger. You can tell if the SCC is on and charging with a steady blue(or yellow or green, depending on SOC(State Of Charge)) LED, or off with a blinking blue LED every 2-3 seconds. When not charging, you can still use the Bluetooth. As the day progresses the LED's will turn to yellow (absorption mode) to green (float mode) depending on clouds and trees, and of course electrical use. With my panels hooked up in series, mine starts up right about the crack of dawn and is charging in bulk mode with a steady blue LED. With the ability to turn off charging, I have notice right off my battery is still > 80% SOC (state of charge) when it restarts in the morning, even with the propane sensor on (my only parasitic load when parked). I like the Bluetooth app. It gives you complete control over battery settings and you can use just about any type of battery including lithium. The app also has a handy history function that is very useful. Some people complain about the range of communication with the Bluetooth. Mine functions like any Bluetooth, about 40 feet of range and that is that. Even with the SCC inside a tin covered RV and me outside, it works fine. I hope someone reads this before going with a PWM charger. For a few more bucks you can have a superior solar system. But for the somewhat lacking manual, I have no cons for this device. I have also ordered the Bluetooth battery temperature and voltage monitoring device for better charging. My batteries are outside the RV while the SCC is inside, this can skew charging parameters. https://www.amazon.com/gp/product/B07RTYGMBD/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 I use two Duracell 78 ah AGM Ultra group 24 batteries along with a 1200/2400 watt inverter, so far this is working out well. This device has load outputs. For the average RV person setting up a simple solar system, this can be ignored. Run your 12 volts supply from the battery as it was originally wired. UPDATE July 1st, 2021: I have recently added two more Renogy 100 watt compact solar panes to the other two, making a total of four. To get these to work on the Victron 75/15 Smartsolar charger, I created two groups of two panels in series, then connected the two groups in parallel. Any other way would be over the rated amps or volts (depending on how the panels are connected. This setup delivers to the battery 15 amps @ 13.6 volts (float), which is as high as it can go. Volts remain the same as the original setup with two panels in series, about 43 volts. I just get double the amps. If I want to get the maximum amps I need to buy the next size up, the MPPT 100/20 controller. As it is now with four 100 watt panels, the charge controller works very well. With 4 panels connected, it turns on quite a bit before sunrise. The extra panels are very helpful in shade or cloudy days(or both). And when the sun shines, the output is strong. ... show more
