Self-heating protects charging—it does not make the battery weatherproof
RUiXU lists an IP20 enclosure for indoor use. The heater draws from the charger and must operate within the specified temperature and charging conditions; do not expose the module to rain or outdoor moisture.
System fit
Confirm heater power, inverter protocol and indoor environment.
Verify 51.2V-class inverter compatibility, communication protocol, recommended charge/discharge settings, cold-temperature operation, battery count, cable architecture and protection. RUiXU lists approximately 103.6 lb per module and dimensions near 19 × 18.1 × 5.23 in.
Cold-weather chargingRUiXU states the heater can support charging down to -20°C (-4°F) when charger power and operating conditions meet its requirements.
Indoor installationIP20 means a dry, protected, ventilated location with adequate rack support and service clearances.
