- Overload protection behavior
- After overload protection is enabled, the inverter output will be restored after 3 minutes, and after 5 times of overload, the output will be off until the inverter is restarted. (102% < load < 110%): an error will be reported and the output will be turned off after 5 minutes. (110% < load < 125%): an error will be reported and the output will be turned off after 10 seconds. Load > 125%: an error will be reported and the output will be turned off after 5 seconds.
- Protection features
- Has PV input current limiting protection, PV input over-voltage protection, PV night reverse current protection, AC input over-voltage protection, AC input under-voltage protection, battery over-voltage protection, battery under-voltage protection, battery over-current protection, AC output short-circuit protection, heat sink over-temperature protection, inverter over-load protection.
