- Maximum charging current: 30 A.
- Maximum discharging current: 30 A.
- Maximum charging and discharging power: 6,600 W.

The battery must be selected in accordance with Sungrow’s compatibility requirements. The voltage range does not imply compatibility with every battery. Charging and discharging performance depend on the connected battery and operating conditions.
Grid Connection and AC Output
- Single-phase connection.
- Rated AC voltage: 220 / 230 / 240 V.
- AC voltage range: 154–276 V.

- Peak apparent power in off-grid mode: 8,400 VA for 10 seconds.
- Rated off-grid backup power: from 3,000 to 6,000 W, depending on the model.
- Maximum power for backup loads when the grid is available: 6,000 W, subject to the configuration specified in the manual.
- Maximum current for backup loads when the grid is available: 27.3 A, calculated at 220 V.
Backup System Sizing
The 6,000 W available for backup loads when the grid is present does not mean that all models can provide 6,000 W continuously during a power outage. Without the grid, rated power depends on the selected inverter. Actual power and backup duration also depend on the battery, its state of charge, PV generation and the loads connected to the backup output.
