Solar Priority Mode: In this mode, the DC power generated is optimized, converted and then used to power connected loads directly. If the solar output is insufficient to meet the load demands, the inverter draws additional power from the battery or the grid. Excess solar, when available, is used to charge the battery, before any surplus is fed into the grid using net metering.
Battery Priority Mode: The inverter prioritizes using stored energy from the battery to power connected loads, while the solar generated is used to charge the battery. If the battery is fully charged, the excess power is fed into the grid.
Grid Priority Mode: Typically switched on when the grid power is cheaper, the inverter prioritizes using grid power to meet the load demands. Solar can be used to complement the supply, charge the battery or send to the grid.
Off-Grid Mode: Also known as standalone mode, the inverter operates independently from the grid, powering the loads using solar and stored battery power.
Backup Power Mode: The inverter switches to this mode when there is a grid outage and solar system fault. It draws energy from the battery to power essential loads. Once all is restored, the inverter automatically switches back to its previous mode.
Grid-Tied Mode: The inverter is connected to both the panels and the grid. Solar is used to power the loads, with any extra energy supplied to the grid. This mode is generally used when solar production exceeds consumption and the battery is fully charged.
Time-of-Used Mode: This is an ‘electricity-rate-oriented’ mode that allows the inverter to smartly optimize energy usage based on variable electricity rates. In this mode, the inverter can be programmed to channel solar and grid power to charge the battery and power loads during off-peak hours when electricity rates are lower; and discharge the battery to supply loads during peak hours when rates are higher.
