■ Inverter DC to AC Converter Details
■ Inverter DC to AC Converter Wiring Diagram
We offer 3 optional working modes for inverter dc to ac converter(transfer time≤4ms):
01 Grid priority mode: When the grid and battery are connected to the inverter, grid will supply power to the loads directly after voltage being stabilized and charge batteries via inverter. When the grid is cut off, the battery will automatically continue to supply power via inverter.
02 Energy saving mode: If the power of the connected AC loads is lower than 5% of the inverter’s rated power, there will be no output from the inverter. Only the chip of inverter is working. The power consumption of the inverter is only 1~6W. The LCD shows the output voltage 0. If the power of the connected loads is over 5%, within 5S the inverter will automatically convert DC to AC to supply power for the loads . The LCD shows the output voltage.
03 Battery priority mode: When the grid and battery are connected to the inverter, battery will supply power to the loads first. When battery capacity is not enough, the grid will continue to supply power automatically.
