ECE One-stop outdoor energy storage system is a beautifully designed turnkey solution for energy storage system. The commercial solar battery storage system is loaded with cell modules, PCS, photovoltaic controller (MPPT) (optional), EMS management system, fire protection system, temperature control system and monitoring system. The system configuration is modular, support multi-machine parallel, plug and play, easy to install and maintenance. The IP54 waterproof shell makes it perfect to adapt to a variety of indoor or outdoor industrial and commercial application scenarios, such as photovoltaic charging stations, industrial parks, farms, etc.
Integrated Solar+ESS design, suitable for access of PV.
New energy vehicles use PV clean electricity as priority.
Off-grid operation can ensure that chargers will work even when there is power outage.
Power transfer and peak-load shiftingto achieve electricity cost saving
On-grid/off-grid switching in milliseconds to realize noninductive shifting between utility grid and PVon wind energy storage systems.
Suitable for remote villages, farms,. etc. where no power deployment onlack of power
Solar give priority to supplying power to the load and charging BESS, when insufficient, the BESS will provide power to the load.
Flexibly meet the access of other backup power sources such as diesel generators and gas generators.
Patented safety design, auto motivehgrade, high-performance LiFePo4 battery, safe and reliable.
Suitable for direct acaess of PW modules and boost green buildings develpment.
Peak and valley operation, effectively reduding electricity bills and operating expenses.
Cormbined with EMS to achieve intelligent operation.
Apply to green emergency power backup.
Suitable for peak-load shifting and saving electricity bills.
Flexibly meet the requirement of load expansion, demand management, investment saving, energy Conservation ard emission reduction.
