I have only acquired this inverter, not too happy with its function. It only gives 84% charge and also when powered by solar panel again when the charge gets to 80% it switches to the grid to send power there. I have sent various emails to your company regarding this and have had no reply

Common issues with the Duracell PD-DH1P-3.6K-G1 inverter regarding charging and switching to grid power include:

1. Grid Absent Alarm (A2): This occurs when the inverter detects no grid connection. If it happens once, no action is needed. If frequent, check the grid connection and frequency using a multimeter.

2. Grid Over Voltage (A0): This can happen when multiple inverters discharge into the grid at the same time, causing voltage to rise above the threshold. To fix this, avoid synchronized discharge.

3. Grid Over Frequency (A3): Similar to over-voltage, multiple inverters discharging simultaneously can raise grid frequency. Desynchronize discharges to resolve this.

4. PV String Reverse Polarity (B7): Incorrect polarity from the PV string can cause faults. Polarity must be checked and corrected before use.

5. Minimum PV Voltage Requirement: The inverter will not register PV input if the voltage is below 90V per string.

6. Time-Based Control Misconfiguration: If the time-based control is not set correctly, the inverter may not charge or discharge batteries at the intended times, affecting grid power use.
