Solar battery discharges outside schedule after EV charger install
Unconfirmed: A user on a community forum describes their solar setup: 15 panels of 620 W (9.3 kWp), a Solis 8 kW inverter and a Dyness 16 kWh battery, with daytime house load of 800 W to 2 kW. Before installing the EV wall charger, they had no grid import. After installation, the battery began discharging outside its scheduled hours. The installer increased the Grid Peak Shaving setting, but now almost all solar production goes to the battery while the house imports from the grid. The user's goal is to prioritize house load.…
- Before the EV charger, the 9.3 kWp system imported no grid power.
- After raising Grid Peak Shaving, nearly all solar charges the 16 kWh battery.
🔎 Why it matters: No official confirmation: the report describes that, after installing the EV charger, the 16 kWh Dyness battery discharges outside its scheduled hours, and that the Grid Peak Shaving setting diverts solar to the battery while the house imports from the grid.
📈 Upside: Not applicable.
📉 Risk: With the current configuration, the house draws between 800 W and 2 kW from the grid during daylight hours while the battery absorbs production from the panels.
