Application Note

Figure 4 – Current paths when grid power is lost.

When the sun goes down and the PV power is no longer flowing through the GT inverter to the loads, the power

stored in the batteries will now provide power to the critical loads panel until morning (see Figure 5).

Figure 5 – Current path from the BB inverter with both PV and Grid loss.
