Product Maintenance and Fault Handling:
| No. | Protections | Remarks |
| 1 | PV current/power limiting protection | When charging current or power of the PV array configured exceeds
the PV rated, it will charge at the rated. |
| 2 | PV night reverse-current protection | At night, the battery is prevented from discharging through the PV
module because the battery voltage is greater than the voltage of
PV module. |
| 3 | Mains input over voltage protection | When the mains voltage exceeds 280V (230V model) or 140V (120V
model), the mains charging will be stopped and switched to the
inverter mode. |
| 4 | Mains input under
voltage protection | When the mains voltage is lower than 170V (230V model /UPS mode) or
90V (120V model or APL mode), the mains charging will be stopped
and switched to the inverter mode. |
| 5 | Battery over voltage protection | When the battery voltage reaches the overvoltage disconnection
point, the PV and the mains will be automatically stopped to charge
the battery to prevent the battery from being overcharged and
damaged. |
| Faults | Handling measures |
| No display on the screen | Check if the battery air switch or the PV air switch has been
closed;
if the switch is in the "ON" state; press any button on the screen
to exit the screen sleep mode. |
| Battery overvoltage protection | Measure if the battery voltage exceeds rated, and turn off the PV
array air switch and Mains air switch. |
| Battery undervoltage protection | Charge the battery until it returns to the low voltage
disconnection recovery voltage. |
| Fan failure | Check if the fan is not turning or blocked by foreign object. |
| Heat sink over temperature protection | When the temperature of the device is cooled below the recovery
temperature, normal charge and discharge control is resumed. |
| Bypass overload protection, inverter overload protection | ① Reduce the use of power equipment;
② Restart the unit to resume load output. |
| Inverter short circuit protection | ① Check the load connection carefully and clear the short-circuit
fault points;
② Re-power up to resume load output. |
