Inspired Energy CR12 Operating Instructions

Optional Discharge Kit:
The unit can be operated to provide backup
power or remote battery power for off-grid
applications.
A battery array kit is available to provide
battery output power from any battery
packs in the charge bays.
Each battery pack contains short circuit
protection and each board is diode-
protected to prevent one battery from charging an adjacent battery.
The battery packs will discharge in parallel, and the output will be battery voltage. Depending on the
batteries used, each CR12 unit can provide a battery array of up to 1.17kWh.
WARNING: the combined battery output from this unit can deliver 1600W / 96A continuously, with
peak power significantly higher.
DO NOT SHORT CIRCUIT. The battery packs are protected from damage but any source of short
circuit will suffer damage &/or may become extremely hot, causing injury.
Remove the battery packs and any personal jewelry (rings, bracelets etc) before working on the
discharge circuit.
To install the discharge kit (available separately):
 Remove all battery packs from the unit & remove the CR12 unit from its rack housing.

Mount the discharge connector to the side of the rack unit using the screws & nuts provided.

Plug a discharge connector to each board
