Pure off-grid or on grid systems have certain limitations in daily use, on and off grid energy storage integrated machine has the advantages of both. And now is very hot sale in the market. Now let’s take a look at several working modes of the on and off-grid energy storage integrated machine.
1. Load priority: PV will give to load and battery first.When the pv cannot meet demand of the load the battery will discharge. When the PV fully meets the demand of the load the excess power will be stored in the battery. If there is no battery or the battery is fully charged, the excess power will be fed into the grid.
2. Battery priority: The pv charges the battery first. When use city power to charge the battery, we need to use the AC CHG (mains charging) function, and also need to set the start and end charging time and the battery SOC point. If the mains charging function is not turned on, the battery can only be charged through PV.
3. Grid priority: The electricity generated by photovoltaics will be connected to the grid first. The electricity generated by photovoltaics will first be integrated into the grid. Start and end discharge times and battery SOC points can be set to deliver power to the grid during peak periods. Priority: Load> Grid> Battery.
