ProtectionandMaintenance 8.1Protection features www.sungoldpower.com No Protection Feature Instruction When the charging current or power of the PV array configured PV input current/power 1 exceeds the PV input rated value, the inverter will limit the input limiting protection power and charge at the rated. If the PV voltage exceeds the maximum value allowed by the 2 PV input over-voltage hardware, the machine will report a fault and stop the PV boost to output a sinusoidal AC wave. At night, the battery is prevented from discharging through the PV night reverse 3 PV module because the battery voltage is greater than the current protection voltage of PV module. When the AC input voltage of each phase exceeds 140V, the AC input over-voltage 4 mains charging will be stopped and switched to the inverter protection mode. AC input under-voltage When the AC input voltage of each phase below 90V, the utility 5 protection charging will be stopped and switched to the inverter mode. When the battery voltage reaches the over-voltage cut-off point, Battery over-voltage 6 the PV and the utility will automatically stop charging to prevent protection the battery from being overcharged and damaged. When the battery voltage reaches the under-voltage cut-off Battery under-voltage 7 point, the inverter will automatically stop the battery discharge protection to prevent damage from over-discharging the battery. After a period when the battery current exceeds that allowed by Battery over-current 8 the hardware, the machine will switch off the output and stop protection discharging the battery. When a short-circuit fault occurs at the load output terminal, the AC output is immediately turned off and turned on after 1 AC output short-circuit second.If the output load terminal is still short-circuited after 3 9 protection attempts, the inverter must be manually restarted after first removing the short- circuit fault from the load before the normal output can be restored. When the internal temperature of the inverter is too high, the Heat sink over- inverter will stop charging and discharging; when the 10 temperature protection temperature returns to normal, the inverter will resume charging and discharging. Inverter over-load After triggering the overload protection the inverter will resume 11 protection output after 3 minutes, 5 consecutive overloads will switch off All-in-one solar charge inverter V3.0 40 Sun Gold Power Inc 12 AC output reverse Bypass over-current 13 protection Bypass phase 14 inconsistency protection www.sungoldpower.com the output until the inverter is restarted.

Prevents AC back flow from the battery inverter to the bypass AC input. Built-in AC input over-current protection circuit breaker. When the phase of the bypass input and the phase of the inverter split do not match, the inverter disables switching to the bypass output to prevent the load from dropping out or shortcircuiting when switching to the bypass. 8.2Maintenance To maintain optimum and long-lasting working performance, we recommend that the following items are checked twice a year. 1. Ensure that the airflow around the inverter is not blocked and remove any dirt or debris from the radiator. 2. Check that all exposed conductors are not damaged by sunlight, friction with other surrounding objects, dry rot, insect or rodent damage, etc. The conductors need to be repaired or replaced if necessary. 3. Verify that the indications and displays are consistent with the operation of the equipment, note any faults or incorrect displays and take corrective action if necessary. 4. Check all terminals for signs of corrosion, insulation damage, high temperatures or burning/discolouration and tighten terminal screws. 5. Check for dirt, nesting insects and corrosion, clean as requiredClean the insect screen regularly. 6. If the lightning arrester has failed, replace the failed arrester in time to prevent lightning damage to the inverter or other equipment of the user. · Make sure that the inverter is disconnected from all power sources and that the capacitors are fully discharged before carrying out any checks or operations to avoid the risk of electric shock. The Company shall not be liable for damage caused by : 1. Damage caused by improper use or use in a wrong location. 2. Photovoltaic modules with an open circuit voltage exceeding the maximum permissible voltage. 3. Damage caused by the operating temperature exceeding the restricted operating temperature range 4. Dismantling and repair of the inverter by unauthorised persons. 5. Damage caused by force majeure: damage during transport or handling of the inverter.
