6 ഓപ്പറേറ്റിംഗ് മോഡുകൾ

The LiTime inverter charger offers flexible charging and output modes to adapt to various energy scenarios.

6.1 ചാർജിംഗ് മോഡുകൾ

You can select one of three charging modes:

1. MPPT First: Prioritizes solar power for charging the battery. If solar power is insufficient, it will not use grid power.
2. MPPT and Grid: Uses solar power as the primary charging source. If solar power is insufficient, it supplements with grid power to charge the battery.
3. Only MPPT: Charges the battery exclusively from solar power. Grid power is not used for charging.

Figure 6.1: Visual representation of the three charging modes.

6.2 ഔട്ട്പുട്ട് മോഡുകൾ

You can select one of three output modes for powering your loads:

1. MPPT First: Prioritizes solar power to supply loads. If solar power is insufficient, it will draw from the battery. If both are insufficient, it will switch to grid power.
2. ഗ്രിഡ് ആദ്യം: Prioritizes grid power to supply loads. If grid power is unavailable, it will switch to inverter (battery) power.
3. ഇൻവെർട്ടർ ആദ്യം: Prioritizes inverter (battery) power to supply loads. If battery power is low, it will switch to grid power.
