Excellent 20KVA Off Grid Inverter With AC Charger
Descripton:
ESS series single-phase off-grid inverter adopts integrated design of solar controller, inverter and isolated transformer. The controller adopts MPPT technology and intelligent battery management design which is very efficient and smart; integrated pure sine wave inverter and low frequency isolated transformer make it with excellent overload performance,
Suitable for a variety of electrical appliances.
ESS series controller adopts modular design with flexible configuration; the inverter is with output of 10kVA~20KVA, supplying power for the places without city power e.g. remote areas, pastoral areas, islands, communication base stations, bringing customer the optimized social, economical and environmental benefits. It supports mains/generator input(optional), take advantages of old diesel generators, saving initial investment and operation maintenance cost.
