We have two of these in parallel with two batteries in parallel. A while back one had to be replaced and now the battery charging and discharging scenarios puzzle me.

During load shedding only one inverter discharges the batteries. And when there is PV during load shedding you can have one inverter charge the batteries while the other discharges the batteries??? However, on AC they share the load, including charging the battery.

When the inverter that discharges the battery reaches 5000W it can go into support mode, and the other inverter will now quite happily discharge the battery unless of course the load doesn't drop fast enough, or it will also go into support mode (this happened today).

My only guess is that there is a firmware mismatch. I've checked battery sharing, discharge settings for both inverters and they are the same. I have even put the battery comms cable in the other inverter but the inverter doing the discharging stays the same.

How do you get access to the installer web page, if you purchased it directly from a vendor.  I am also setting it up myself and dont make use of an installer.
