■ DC to AC Inverter Details
■ DC to AC Inverter Wiring Diagram
We offer 3 optional inverter working modes (transfer time≤4ms):
1) AC priority mode (d0)
A. When the mains power is normal (in line with the inverter power input voltage range), on the one hand, the mains power charges the battery (if built-in solar controller, the mains power and solar energy charge the battery at the same time); on the other hand, only the mains power supplies power to the load (the load does not consume solar and battery energy);
B. When the mains power is abnormal (the mains power is beyond the working range of the inverter or the mains power is interrupted), the inverter will switch to the battery mode, and the battery will supply power to the load (if built-in solar controller, when the solar power is greater than the load power, the load will be completely supplied by the solar energy, and the excess energy will charge the battery; when the solar energy is less than the load power, the insufficient part will be supplemented by the battery. The load is supplied by solar energy and battery together).
2) PV priority mode (d1)
A. When the solar is normal (in line with the solar input voltage range of the inverter), if the solar power is greater than the power of the load, the load is completely powered by solar, and the solar excess enengy charges the battery, when the solar power is less than the power of the load, the insufficient part is supplemented by the battery, and the solar and the battery supply power to the load together. If the battery is low volage due to the load, then the inverter will turn to the AC mode for power supply, and the solar will only charge the battery;
B. When the solar is abormal (the solar volage exceeds the working range of the inverter or the solar is interrupted, the inverter will directly switch to the AC mode for power supply, and the mains power will charge the battery.
3) Battery priority mode (d2)
A. When the inverter has no low-voltage battery alarm, even if the mains power input is normal, the inverter will switch to the battery mode, and the battery will supply power to the load. When the solar power is greater than the load power, the solar power will supply power to the load completely. and the excess enengy will charge the battery. When the solar power is less than the load power, the insufficient part will be supplemented by the battery, and the solar and battery will supply power to the load together;
B. When the battery is low voltage (i.e. the voltage of a conventional single battery is 11vdc) and the mains power input is normal, the inverter will switch to the AC mode and the mains power will supply power to the load completely, while the solar energy will charge the battery but the mains power does not charge the battery.
