Inverter working mode and connection diagram
1. Battery Priority Mode (Off-Grid Mode for solar power system)
First Priority on Battery Power: In off-grid scenarios, our inverter prioritizes battery power to supply AC loads. Ideal for locations without a utility grid, such as remote solar power systems.
Efficient Battery Usage: Continues drawing power from the battery bank until reaching a predefined minimum state of charge. Non-critical loads are automatically shut off to conserve battery life for essential equipment.
Optimized for Solar Power: In events like nightfall or low solar output, the system relies solely on battery power. If integrated, a backup generator can be automatically activated to ensure continuous operation.
2. Utility Grid Priority Mode (Backup Mode)
First Priority on Grid Power: In backup mode, the inverter draws AC power from the utility grid first, reserving battery power for outages. This prevents unnecessary battery drain when the grid is stable.
Automatic Battery Charging: When connected to the grid, the inverter charges the battery bank using solar power or other available sources, maintaining optimal battery levels for backup use.
Seamless Transition: On loss of grid power, the inverter instantly switches to battery mode with minimal disruption, ensuring uninterrupted power supply to both critical and non-critical loads. A backup generator can be set to start automatically to either continue powering loads or recharge batteries.
