During periods of high demand
Solar power and battery energy can work together, depending on the programmed operating mode and inverter capabilities.
This helps reduce the amount of electricity drawn from the grid.
During the evening
When solar generation decreases or stops, the battery bank can supply energy to the connected loads.
This allows stored daytime solar energy to be utilized during periods of low solar production.
During a grid outage
The hybrid inverter can provide backup power from the battery and available solar generation, subject to the inverter’s configured operating mode and the connected-load requirements.
