Review: It was so easy/user friendly regarding functionality, installation, and everything else that’s important! The little monitor would always tell me accurate readings in the year+ that it was installed in to my camper van.
Review: Other than a issue with a TAX invoice as in they do not supply one a major pain In Australia if you want to claim the unit as a Business expense as is what i wanted to do. The unit is by far the best one i have tested so far. It does not just charge and cut off it also supplies power to the connected devices so as not to run the battery down when the battery is full and the sun is still shinning. So if you don't need to right this off TAX wise i would recommend it. So 5 stars for the Item 1 start for the seller.

*by J***U on 22 December 2025*

I rarely leave reviews and in most cases only when I am really annoyed by a product. But this unit is really great at a very resonable price! Works very well, is compact, and has many great features that only a combined dual (solar and alternator) charger can provide. For example charging my starter battery when the solar battery is full. I think I had a small parasitic drain on the van which caused the battery to be empty after a few weeks of not driving. With the renogy charger that is no longer a problem. And of course the main function to support dual charging is also great. I specifically used the smaller version (30A) to limit stress on the alternator . That is probably the only missing feature I can think of: configure the max draw from the alternator in the app. But with the 30A version that is not really a problem. And I anyway only have 400W of solar, so 30A is fine.
