Hi everyone. Help needed with this one. Currently have a system in place that needs an upgrade, but I am in two minds here. Currently sitting with a household using roughly 15-20kWH a day. Calculations came to an inverter spec of 8kW, but want to boost that up to 10KW for expansion. Currently sitting with a 5KVA(4000W) Axpert Hybrid inverter with 2x 5.5kWH Hubble AM2 batteries(recently installed due to a warranty claim on previous batteries), 1x 125A battery isolator (145VDC and 60Amp MPPT). Night time kWH consumption is about 8kWH so the 11kWH backup is fine. Looking at doing 9x 380W JA mono solar panels gave me 124.86VDC and 34.41A which would be fine for the MPPT in winter months for any expansion on the VDC. Am I correct in saying this or any suggestions on my solar panel configuration? Now for the expansion on the system I think it would work best to run 2x 5KVA inverters in parallel and both connected to the 2x 5.5kWH batteries. Should I look at putting in another 5kVA Axpert inverter on this system, however this will only get me to 8000W, where I would like to get to 10 000W. This means upgrading my inverter to perhaps a LUX SNA-5000 with a max 6000W PV array, 480VDC and 100A solar charging rates. 14x 455W JA solar panels ( 7 in series and 2 in parallel 344.96VDC and 20.32A. Think it would be best to have all the panels connected to 1x inverter rather than splitting them for charging purposes - any thoughts on this? Going to use the second inverter purely for the additional 5kW consumption of the house then. Should I rather look at a different inverter make/brand like `Sunsynk or `Growatt? I would really appreciate some help and advise here with your thoughts. many thanks!
