Product Details :


For commercial buildings such as schools, factories and petrol stations that require higher energy demand, solar PV system with battery storage can enable business to maximise their energy independence and reduce peak power demand; For business without solar PV system, battery storage can enable business to store energy from the grid at off peak price and use at peak time.

GSL ENERGY ESS3015k provides one-stop solutions for commercial and industrial facilities to reduce your electricity bill, protect your business from rising energy expenses; generate stable revenue from renewable energy production and subsidies; and ultimately reduce carbon footprint.


Product Description
The system is simple, practical, convenient and flexible. 

It is composed by the mainframe and solar battery components. The mainframe integrates GSL ENERGY lithium battery pack, inverter, controller and so on. 

The solar battery components consist of solar panel, solar battery bracket and cable box etc. 

In the daytime, the solar energy is stored in the lithium iron phosphate battery and then transformed into 400VAC alternating current through the inverter for the household appliances. The excess energy is stored in the lithium iron battery.

In dark or rainy days, the storage energy of battery will be converted into 400VAC alternating current by the inverter to supply the household appliances.
