I am planning on installing one full stack EQ4800-L9 (41.93kWhr) , however I wanted to get up to 50kWhr Usable.
Does any one know:
If two EQ4800-L6 stacks can be combined in parallel using a combiner box
or
If two EQ4800-L6 stacks can be combined in Series (309.1v x2 = 618.2 volts) which is still below the H3-15.0 Smart max battery voltage of 800v ?
Thank you!
No you can’t combine them on a single inverter, it isn’t the voltage/current that is the limiting factor the comms protocol is designed for a single BMS to manage multiple packs, it cannot be linked to a second BMS.
Options would be, if you are 3 phase use the H3 Pro which can cope with 2 seperate BMS / battery inputs and the inverter manages their balance, or, if single phase go with 2 inverters (H or KH) and link them in parallel, again that would give you full control over 2 separate battery packs.

Perfect, Thank you Dave for the quick reply. That makes sense. I have 3ph and I didn't think the H3 Pro was available in Australia as yet (cant see it on the CEC list). So for now I will have to live with the L9 setup. Its a shame that we can't use the full 50kwhr federal credit in this case.
Thanks for clarifying!
