I’m looking to replace my current Enphase inverter and battery because they claim now that they can’t support “Off-grid”. I’m looking for an inverter and batteries from 10-12Kwh to attach to my 10 405V panels and Electrical backbone.
@Patrick_Allen what is your current Enphase battery? Is it the older compact 1.2kWh battery?
The new Ensphase Encharge battery system is off-grid compatible but only in combination with the new IQ System controller 2 (see this end of this article for more details - Enphase Micro Inverter Review — Clean Energy Reviews)
If you have an Enphase system and want to add a larger battery you will need an AC-coupled battery system such as one of the batteries in this chart - Home solar battery comparison charts — Clean Energy Reviews
