About PWRcell Battery

The PWRcell Battery is the storage component of the
PWRcell system. The battery can be used for grid-
connected solar applications, such as Self Supply, Rate
Arbitrage, and Clean Backup power. The battery is
designed to work seamlessly with PV Links and the
PWRcell Inverter to form the PWRcell system for grid-
tied solar-plus-storage.
The PWRcell Battery uses the REbus 380VDC nanogrid
to connect the PWRcell Inverter. The REbus nanogrid
automates the flow of power to enable plug-and-play
setup and operation of PWRcell equipment.
In Figure 2-5, a REbus-compatible PWRcell Inverter (E)
is directly connected to PV Links (B) and PWRcell
Battery (C) on REbus (D), the DC nanogrid/lines (D). To
the right of the inverter are AC lines: 240VAC or 208VAC
for grid and home loads (G), and protected loads (H).
Load support varies by model and number of battery
modules attached. Refer to
information.
