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. ### ⭐⭐⭐⭐⭐ Great features, good price *by on Reviewed in the United States 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. ### ⭐⭐⭐⭐⭐ Literally Genius *by on Reviewed in the United States 12 June 2026* This bit of kit was a real find.Does all the jobs beautifully! Have removed my solar charge controller, no longer needed and this unit is way more efficient. Finds my alternator and balances charge between my lead starter and lithium domestic.It like perfect problem solving in a plug and play box.
