✓Set the battery usage time in peak or shoulder time.
For example: 08:00–10:00 & 14:00–20:00.
✓Different usage times can be set on weekdays and weekends.
✓Forced charge functions
Set the charge time range and target SOC
For example: 00:00-05:00, 50%
Customisable Battery Usage Time and Forced Charge
Prioritize local energy supply at high prices, and arbitrage with forced charge to reduce bills.

✓Max. off-grid power (PV + battery): 5 kW
✓Max. off-grid power (battery only): 3 kW;
and
✓Max. switch time to EPS mode: 10 s.
The battery will be utilized down to this
level at most when connected to the
grid. This ensures some battery
reserves in the event of a blackout.
Q: What if my battery is already
depleted from daily cycles when the
