How long does a fully charged Bull energy storage product last?

Battery life depends on the energy consumption rate and the size of the energy storage system. It can be calculated by dividing the battery capacity (kWh) by the load power (kW). For example, a 30kWh Bull energy storage product lasts approximately 15 hours on a full charge at an average load of 2kW; and over 30 hours on a single charge at an average load of 1kW.

What are the charging methods for Bull energy storage products?

Bull energy storage products can typically be charged via AC adapters, solar chargers, and car chargers. Some models also support generator charging, dual AC charging, or dual solar panel charging. Please consult the product manual or customer service for specific charging methods.

What maintenance is required for Bull energy storage products?

Bull energy storage products require virtually no maintenance. However, users should ensure that the battery charge level never drops below 10%. Before long-term storage, the device should be fully charged and connected to the dedicated maintenance input port, maintaining a constant single-phase AC power supply.
