Page 19: Powering On The System
Powering On the System When LED2 is steady green (meaning that the inverter is grid-tied), do not turn on any DC switch. Otherwise, the inverter may be damaged because the insulation resistance is not detected. • Before turning on the AC switch between the solar inverter and the power grid, check that the AC voltage is within the specified range using a multimeter set to the AC position. - Page 20 Indicator Status (Blinking Fast: On for Description 0.2s and then Off for 0.2s; Blinking Slowly: On for 1s and then Off for 1s) PV connection Steady green At least one PV string is properly connected, indicator and the DC input voltage of the corresponding MPPT circuit is at least 200 V.
