Introduction to solar off-grid inverter:
Solar off-grid inverters are pure sine wave intelligent inverter power supplies. They convert DC120V/DC240V/DC480V direct current from batteries into sine wave alternating current of AC220V/AC110V through solar inverter power supplies, which is used by user loads. Solar power generation systems consist of components such as solar panels, charge and discharge controllers, inverters, and batteries. Depending on the usage mode, they can be divided into several types: pure inverter type; grid-complementary type; inverter-controller integrated machine; solar inverter system suitable for DC120V, DC240V, or DC480V;
inverter
Operating status description: (Capable of adding mains power auxiliary charging function)
When both AC input and DC input are normal, the battery pack (DC power) is isolated and filtered, then inverted into pure AC power, which is supplied to the load through static switch 1 (i.e., DC inverter power supply);
2. When the AC input is abnormal and the battery input is normal, the DC power is isolated and filtered, then inverted into pure AC power, which is supplied to the load through static switch 1 (i.e., DC inverter power supply);
3. When the AC input is normal and the DC input is abnormal, power is supplied to the load through static switch 2 from the AC input (i.e., AC power supply);
4. The conversion process is intelligent, with an extremely short conversion time of less than 5ms, ensuring uninterrupted power supply;
