The black series power frequency off-grid inverter has a solution
Solution 1: Mains power is given priority. In the event of a power outage, the battery complements the load and is used in the backup power supply, commonly known as power outage treasure
Solution 2: Battery First, when the battery voltage is low, the mains power supplies power to the load through bypass, which is often used in solar power generation systems.
