Good bang for your buck, works great with my aux battery in my van paired with two 230W panels. Great, accurate monitoring, easy to use app, plug and play install and it really seems to get the absolute most out of the panels.

I started my DIY solar journey with Renogy and used to think Victron was overpriced. After finally trying it out and using both with similar arrays, I get it. The performance is unparalleled. The app is incredible, offering deep customization of parameters, and the technical documentation is actually descriptive and helpful. I love the ability to configure the charge profile to be gentle on my battery bank, and the integration capabilities with other Victron equipment are truly awesome. I’m replacing my old Renogy MPPT with a second Victron today. It is absolutely worth the investment.

This charge controller is a powerhouse. Charges my Lifepo4 battery in 2 hours in the morning in good sun and that’s with the charge rate reduced to 40 amps wow. Love the Bluetooth interface and the wiring of the unit was easy. Victron quality shines through great product.

This is a fantastic product! I installed with with two 220w solar panels and a 300ah Lifepo4 battery. Everything went smoothly and works as intended. Learning the app was quite easy too.

Its fantastic it works like a clock its just plug an play you dnt have to monitor it and its easy to instal. The price is a bit tall but its woth it I've had it for months now and it just goes and i like the app its very user frendly it handles power really good i had 2 665 panels connected to it and it handle it fine and change my battery fast. The only thing is that it smalls a bit and gets hot but that's no problem for me knowing that i have no electric bill to pay. 😁😁 I've read other reviews on this mppt and they complain about the Bluetooth range but to be honest it's not bad, Bluetooth signals\ waves don't travel that far ether to that's no problem for me. Victron is good.

Solid reliable I have 3

I looked at a lot of controllers when I finally decided to splurge on this one. The quality is excellent, the terminal screws are the best I've seen. My only complaint is that additional purchases are required in order to have an "at-a-glance" display and a complete profile of your system.. The bluetooth function gives a great deal of information and programmable features, but the connectivity range isn't what I expected. I have to be within 20 ft to locate the controller. When I read the manual on this product, I saw screenshots with other valuable information I felt would be helpful(for overall system health and troubleshooting) but were unobtainable with my unit. After further investigation, these additional screens were from a display module, charger, BMS, and inverter that are sold separately and only discoverable if they are Victron Energy products.

It’s a brilliant bit of kit! It charges battery’s and easy to set up, iv recently upgraded from a generic not mppt solar charger and it was not stopping charging at 100% giving me voltage problems and it would charge slowly. This on the other hand, iv hooked it up put the setting of the battery In and it just works! No voltage problems and charging faster than the old one! My advice is to spend the money! You get what you pay for!!!

Very good quality

I was amazed by the performance compared to previous low range hybrid inverter/MPPT charger. Get's more power from the same system!

fonctionne parfaitement

Bonjour Excellent matériel De très bonnes qualité Très simple à utiliser Je le recommande sans problème
