This is the most energy-efficient method, with all the battery power coming from solar energy, and is usually used in areas with good radiation conditions. 28 5.5 Time-slot charging/discharging function The ASF series is equipped with a time-slot charging and discharging function, which allows users to set different charging and discharging periods according to the local peak and valley tariffs, so that the utility power and PV energy can be used rationally. When mains electricity is expensive, the battery inverter is used to carry the load; when the mains electricity is cheap, the mains electricity is used to carry the load and charge, which can help customers to save electricity costs to the greatest extent. The user can turn on/off the time-slot charging/discharging function in setup menu parameter 46 and 53.and set charging and discharging slot in parameter 40-45, 47-52. Below are examples for users to understand the function. NOTICE Before using this function for the first time, please set the local time in parameter items 54, 55, then the user can set the corresponding time slot according to the local peak and valley tariff charges.

Protection and Maintenance 8.1 Protection features No Protection Feature Instruction 1 PV input current/power limiting protection When the charging current or power of the PV array configured exceeds the PV input rated value, the inverter will limit the input 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 3 PV night reverse current protection module because the battery voltage is greater than the voltage of PV module. 4 AC input over-voltage protection When the AC input voltage of each phase exceeds 280V, the mains charging will be stopped and switched to the inverter mode. 5 AC input under-voltage protection When the AC input voltage of each phase below 170V, the utility charging will be stopped and switched to the inverter mode. 6 Battery over-voltage protection When the battery voltage reaches the over-voltage cut-off point, the PV and the utility will automatically stop charging to prevent the battery from being overcharged and damaged. When the battery voltage reaches the under-voltage cut-off point, 7 Battery under-voltage protection the inverter will automatically stop the battery discharge to prevent damage from over-discharging the battery. 8 Battery over-current protection After a period when the battery current exceeds that allowed by the hardware, the machine will switch off the output and stop 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 second.If the 9 AC output short-circuit protection output load terminal is still short-circuited after 3 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 inverter 10 Heat sink over-temperature protection will stop charging and discharging; when the temperature returns to normal, the inverter will resume charging and discharging. 11 Inverter over-load protection After triggering the overload protection the inverter will resume output after 3 minutes, 5 consecutive overloads will switch off the output until the inverter is restarted. 38 No Protection Feature Instruction 11 Inverter over-load protection 12 AC output reverse 13 Bypass over-current protection (102%<load<110%) ±10%: error and output shutdown after 5min; (110% < load < 125%) ±10%: error and output shutdown after 10s. Load > 125% ±10%: error reported and output switched off after 5s. 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 14 Bypass phase inconsistency split do not match, the inverter disables switching to the bypass protection output to prevent the load from dropping out or short-circuiting when switching to the bypass. 8.2 Maintenance 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 anti insects net as required. 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. DANGER · 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. 39 9.
