Solution

Phase I already installed 1 MWp of photovoltaic capacity, but without energy storage support.
The facility still needs to purchase hundreds of thousands of kWh from the grid each month, resulting in high electricity costs.

This is a customer operating a Tesla repair shop in Zhuhai. Their electricity usage involves a special “phase change” consumption method, while local power resources are monopolized by the village, resulting in electricity prices that lack market fairness, reaching as high as 1.5 RMB per kWh.

This is a customer in Huizhou. The customer has two 1000KVA transformers, and the factory building is self-owned. One transformer supplies power to their own factory, while the other serves tenants. To reduce electricity costs and achieve peak-valley arbitrage, the customer has installed two 522kWh energy storage cabinets, placed respectively under each transformer.
