Mojave ESS Battery
The Mojave ESS battery is sold for use with the Mojave inverter. It is a nominal 48-volt lithium-ion
system intended for use in non-dwelling spaces. The battery can be charged and discharged at up
to 200 Adc continuously.
This battery incorporates passive overcurrent protection in the form of circuit breakers and fuses.
The battery incorporates active BMS protection for overcurrent, overvoltage, over-discharge, and
over-temperature conditions. The battery communicates operating limits to the connected inverter
via CAN communications. It self-protects in case these limits are violated.
