Features: Battery Warm up function
Official user manual
Sources
Warm up function is exclusively available in warm-up versions. All batteries must be warm-up versions; otherwise the Warming up function will not operate. Heating control is based on internal cell temperature rather than ambient temperature. Battery can only discharge when internal temperature is above -10°C and only charge above 0°C. These internal-cell limits are separate from root-reviewed warm-up model-table operating ambient ranges. Self-heating state: SOC >= 10%, MinCell Temperature < Start Temperature, not in low-temperature protection, within set heating time. Resistor is powered by battery; inverter power control not affected. Inverter-controlled heating: SOC < 10% or in low-temperature protection, and MinCell Temperature < StartTemperature within set heating time. Resistor powered by inverter; inverter can only provide heating power and cannot respond to other charging/discharging requests. Page 11 app controls print heating start temperature 1~9℃ optional, stop 10~15℃ optional, and three time periods. Values are control settings, not battery charge/discharge operating limits.

PDF page 16, Fire Situation: In situations where the battery is on fire, if it is safe to do so, disconnect the battery module by turn off the circuit breaker to shut off the power to the system. Use FM-200 or CO₂ fire extinguisher for the battery and an ABC fire extinguisher for the other parts of the system. Under any fire situation, please evacuate the people from the building immediately before trying to extinguish it.

Evidence score

Research pending0% documented

The Evidence score uses the priorities you choose. It counts published documents, such as certificates and warranty terms, and it compares a documented figure with the best documented figure of the same kind. It does not count owner reviews, and it is not a verdict on product quality or on how many people have reviewed it. A low score can mean little is documented, or that a documented figure is below the best of its kind. Undisclosed data scores 0.

Missing for this product: Certificates evidence needed; Warranty term needed; Warranty energy disclosure evidence needed; Lifetime / capacity evidence needed; Cell model disclosure evidence needed.

48 V · Format not recorded · Rated capacity

The warranty term and the lifetime energy are each scored against the best documented value for a home storage battery: a value earns its share of that best, times the weight. A documented value always earns points; an undisclosed one earns 0.
