9.1.2 Connecting the PV Power Supply

Prerequisites
You can perform PV power-on commissioning only when sun exposure is sufficient.
Procedure
Step 1 Check that the PV input voltage is in the range of 200 V DC to 980 V DC using a multimeter.
Step 2 Turn the PV output switches to ON for the SJB.
Step 3 Turn the PV input switches to ON for the cabinet.
Step 4 Check the connections of PV module power cables. If the power indicator (green) on the front
panel of the HSU is on, the cables are connected correctly. If the indicator (green) is off, the
positive and negative power cables may be reversely connected and need to be corrected.
