*Inverter trips off line within two cycles on over/under voltage and frequency faults. It should be noted that the voltage trip limits can be up to 1% off from the actual grid voltage at full load due to the 1% regulation of the isolation transformer. The PV-225208 uses phase to phase voltage measurement to detect the under/over voltage trip limits. For an unbalanced, single phase voltage variation of +10% and -12% as per UL1741 the trip limits must be set to 220V for maximumAC voltage and 193V for minimum AC voltage. Consult your local utility for their specific requirement.
