IP20 can only be placed in a dry room, but it has a wide temperature tolerance of -30 ℃ to 50 ℃. 25kg per module, easy to move, can be used in campsites and construction sites, replacing fuel generators, quiet and environmentally friendly.
The battery pack is replaceable! When there is a power outage, replace the battery with a new one and it takes 5 minutes to complete. The cash register and refrigerator keep running. Small convenience stores use this to avoid product damage or data loss, making emergency response extremely efficient.
Can it! Basic 20.48kWh, stacked to 30.72kWh like building blocks. A small shop can use 20.48kWh, but if you want a bigger one, you can simply add modules without having to replace the whole machine, saving money and effort.

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr01/29/2026 -
Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
