Environmental Characteristics
Operating Temperature
Range - Discharging
Discharge: -20°C to 60°C (+/-5°C)
BMS shuts down discharge when the internal cell
temperature sensor measures outside this temeprature
range. This is an abnormal situation and requires
investigation. As such the battery requires a manual restart
before it can be operated again.
Operating Temperature
Range - Charging
Charge: 0°C to 50°C (+/-5°C)
BMS shuts down charging when the internal cell
temperature sensor measures outside this temperature
range. It will automatically restart once the temperature
sensor measurement moves back into the range 5°C to
50°C (+/-5°C).
Cooling
Natural convection
No fans... install in a shaded area.
Physical Characteristics
Battery mounting options
In a standard 19° rack or
horizontally, vertically or on
either side
RedEarth can provide its pre-wired RACK19 system with
built-in main battery breaker and Victron BMS-712 battery
monitor. It also has a range of fully pre-wired inverter
battery systems for both on and off-grid applications.
