Pro Tip: You may connect any REbus device to any one of the bidirectional inputs, or up to 30A of
parallel devices. In practice, this means you can connect one REbus compatible smart battery to
each input, or up to three PV Links. Always follow applicable codes when calculating ampacities and
selecting and installing wiring and overcurrent protection.

Pro Tip: If your system does not include battery storage but you expect to add batteries in the future,
you can install a Protected Loads panel at the same time you install the inverter. The Protected Loads
panel will be fed by the grid through the inverter while the system operates in Grid Tie mode.
