I have a BLUETTI EP600 + 2×B500 system with 16 solar panels (two arrays / two MPPT inputs).
Currently I’m facing the following issue: solar generation is not used as a priority while the grid is available. Even when there is good sunlight, the house continues to draw power from the utility grid, and the PV power is barely used.
In practice, the solar panels start powering the house only if I manually disconnect the main grid.
I would like the system to work with the following priority:
- Solar panels → house loads (priority)
- Excess solar → charge the battery
- If solar is not enough → take the deficit from the grid
- At the same time I want to keep the battery around 80–90% as backup in case of a grid outage.
Questions for EP600 owners:
- Which settings in the BLUETTI app should be configured so that PV becomes the primary energy source?
- Is this related to SoC Low / Work Mode / Grid charging settings?
- Is there a specific inverter operating mode that should be enabled?
I would really appreciate if someone could share their configuration or screenshots of the settings or advise me about possible solutions?
