Electrical Connections - Sofar solar HYD 10K-20KTL-3PH User Manual

Before performing electrical connections, ensure that the DC switch is OFF.
Since the stored electrical charge remains in a capacitor after the DC switch is
turned OFF. So it's necessary to wait for at least 5 minutes for the capacitor to be
electrically discharged.
HYD 10-20KTL-3PH inverter is intended to be used in PV system with
battery storage. If not used as intended, the protection provided by the equipment
may be impaired.
