Connecting Multiple Inverters
Connecting Multiple Inverters
For installations with multiple inverters, a separate PV array is required for each GT Inverter unit. The output of each GT Inverter feeds a separate
When connecting multiple inverters, complete the wiring and perform the commissioning procedure for each inverter one at a time. For wiring instructions, see “Connecting the DC Wiring” on page
If inverters “share” more than one PV array, an input current difference of over 1 A between arrays can cause short circuit failure in each inverter. This failure will also generate hazardous voltages around each unit.
In multiple inverter installations, it is very important to ensure each inverter is correctly connected to its own PV array(s) and that no wires are crossed. For example, connect PV1 positive (+) and PV1 negative
Do not connect PV1 positive (+) and PV2 negative
