What to do if my LogicPower Inverter has reversed input polarity?
If your LogicPower Inverter indicates reversed input polarity, it means the input polarity was connected incorrectly during installation. Check if the anode and cathode of the inverter input are connected in reverse. If they are, correct the polarity.
What does it mean if my LogicPower EA33KTLSI Inverter reports a BOOST lightning protection fault?
If your LogicPower Inverter is showing a BOOST lightning protection fault, it means that the BOOST lightning arrester is either not connected or has been damaged. Check if the BOOST lightning arrester is connected; if not, connect it.
How to fix reverse phase sequence of power grid in LogicPower EA33KTLSI Inverter?
If your LogicPower Inverter indicates a reverse phase sequence of the power grid, it means the power grid ABC phase sequences are connected in reverse. To resolve this, adjust the AB or BC or CA two-phase connection.
What to do if my LogicPower Inverter indicates an inverter circuit fault?
If your LogicPower Inverter reports an inverter circuit fault, it's due to abnormal external conditions causing the inverter's internal circuit protection to activate. This can be caused by drastic variations in external conditions, resulting in excessive output current. The inverter monitors external working conditions in real-time and should return to normal operation automatically once the fault is resolved. Also, check the inverter's output cable for any short circuits.
