IMPORTANT:
Neither the GS8048A nor the GS4048A can stack with the previous model GS8048.
The GS8048 can share a HUB product with the others if it is wired independently.
The GS8048A can be stacked with the GS4048A using HUB products. To optimize
the Power Save function, GS4048A inverters should have higher rank numbers than
any GS8048A inverter. This is true regardless of the quantity of either model. In
addition, the GS4048A should not be the master inverter in a mixed system.
The master inverter must always be connected to port 1 on the communications
manager. Connecting it elsewhere, or connecting a slave to port 1, will result in
backfeed or output voltage errors which will shut the system down immediately.
Installing multiple inverters without stacking them (or stacking them incorrectly)
will result in similar errors and shutdown.
Although stacking allows greater capacity, the loads, wiring, and overcurrent
devices must still be sized appropriately. Overloading may cause circuit breakers to
open or the inverters to shut down.
