Victron Energy SmartSolar MPPT Solar Charge Controller (Bluetooth) - MPPT Charge Controller for Solar Panels - 100V 30 amp 12/24-Volt

Probably the best quality MPPT money can buy. I have the 100/30 set up in my campervan on a 140w solar panel and it’s keeps my 2 140ah leisure batteries charged whenever I’m away on a trip. It’s very easy to set up and it’s pretty much plug and play. The Bluetooth app interface is also easy to use and provides good information for your electrical set up. Size wise it’s a big heavy unit but that shows the quality of it if you ask me. The efficiency is excellent and it’s never skipped a beat in my 2 years of ownership.

When it comes to solar charge controllers, these are the boys. Don't waste money on the 'toy' ones, go Victron. Just wish they'd stick to the design with solar connector socket s built in.

As you would expect, victron delivers another solid, reliable product with excellent capabilities. In a world of overstated and often unreliable (in some cases, dare I say fraudulent) claims for performance and specifications, Victron can be relied upon to give you exactly what the spec sheet says. I think I'll only buy Victron from now on. Too many other purchases have disappointed. But not this one.

Couldn't be happier with it. Does what it's supposed to, extremely easy to set up and monitor through the Bluetooth app. Awesome bit of kit

Great solid bit of kit. Fitted this to my van along with a 400w panel and I rarely look at my battery level now. I set it up about 18 months ago and I've never needed to mess with it since in any way, it just does it's stuff in the background and keeps my leisure battery topped up. Perfect

Very solidly put together. Easy to install and is very efficient in charging my campervan leisure battery even in overcast conditions, though obviously much better in sunshine.

It looks a good bit of kit and a decent price

There are so many models it was hard to figure out which to choose from. I used the MPPT Calculator on the Victron site which suggested this model whilst taking into account some overpanel. In use, it started generating power earlier than another charge controller which has a higher startup voltage. Previously on some darker rainy days, no power was being generated - extracting more power at this time of year is a welcome bonus. The Bluetooth range on this charge controller is pretty amazing - about 15 meters and still connecting to the App. I compare this to the BMS which is 5 meters or thereabouts. I'll continue to monitor its performance and may look to swap over a second string to a victron charge controller.
