Hi,
I am putting up an Enphase micro-inverter based PV system (10kW) and I'm trying to work out an AC coupled battery backup system. I've read this guide, https://www.victronenergy.com/live/ac_coupling:start and want to make sure I'm understanding correctly.
Could someone please confirm/deny the following points/questions:
--based on the VA rating of the Quatro or Multiplus, I would have to split the PV output in to two groups....for the 8000VA Quatro for example, I could have up to 8000 watts of PV connected to the Quatro and the other 2000 watts would have to be connected directly to the grid
--for that same 8000VA Quatro, I would need a minimum of 570amp hours of 48v lithium batteries....I could add additional batteries to increase capacity if desired
Thanks,
Kevin
