What you will see
- ID044 or ID087 after installation or rewiring
- One input carries far more current than the other
Why it happens
SOFAR inverters can run their two inputs separately or joined. If the setting and the wiring disagree, the inverter reports an error.
Diagram
Setting must match the wiring
Independent mode
Each string on its own input. Setting: independent.
Parallel mode
One string split across both inputs. Setting: parallel.
Mismatch
Wiring and setting disagree: ID044, or uneven current ID087.
What you can check yourself
- Note whether the strings were recently rewired
What not to do
- Do not change input mode settings yourself
