Suitable for household and industrial-commercial photovoltaic power stations. It stores photovoltaic power during the day and releases it during peak night hours to achieve "peak shaving and valley filling", reducing electricity costs. It automatically switches to emergency power supply in case of sudden power outages to ensure continuous power supply for key equipment.
Applicable to off-grid scenarios such as RVs, camping, field exploration and border posts. The lightweight design facilitates carrying and installation. A single charge can meet the long-term power supply needs of multiple devices, replacing traditional diesel generators with green, environmental protection and no noise.
Can be used as UPS uninterruptible power supply and industrial equipment backup power supply. It features fast response speed and stable power supply, effectively coping with power grid voltage fluctuations and sudden power outages, avoiding losses caused by equipment shutdown. Widely used in data centers, electronic factories, medical equipment and other scenarios.
