Hope everyone is doing well. Below are the photos of the combiner box and sub panel. Here are the issues that we are having.
When we first installed the system we just powered up inverter number 2 it was attached to the battery and was charging it perfectly and pulling good numbers from the PV. Then we installed PV1 and installed the combiner box and the powered up the loads. The inverters would kick on one at a time to power the loads up to 12kwh and then would short out and then the other one would kick on and go all the way up to 12kwh and then short out.
Now inverter 1 is running perfectly but if I throw the loads breaker on inverter 2 it shorts the whole system out and shuts off power to the house. Then if i put inverter 1 in standby and turn on inverter 2 loads nothing happens at all no PV to loads and no PV to battery only about 100w is trickling into the battery.
I think there is a short in inverter 2 that is causing the other inverter to short when the loads are on.
If there are any suggestions or If I don't have the combiner box wired right please let me know. thank you!

- Dongles won't connect to server
- reset dongles
- all three lights come on when local connected and stays on after but does not show online on the internet
- Inverter #2 will not produce PV power only 100w at a time to charge the battery when over 30 panels are connected to it
- This was the first inverter installed and was functioning fully when we first installed the system and now will not power any loads
- when the load breaker is switched from OFF to ON it shorts out inverter number 1 and it shuts off power to the whole house until I turn OFF loads on number 2 and then restart inverter 1 .
- 3. When in parallel neither inverter works.
I think there is a short in inverter 2 that is causing the other inverter to short when the loads are on.
