Technology and Features
Zhilian Shengda series power frequency off-grid photovoltaic inverter all-in-one machine for sale uses charge controller, inverter Integrated design of converter and transformer isolation. The inverter's pure sine wave output power frequency transformer isolation ensures that the AC output is safe, stable and reliable. The solar controller adopts a control algorithm and intelligent battery management design to be intelligent and efficient and suitable for various electrical appliances. The system supports mains/diesel generator AC input (product optional). The oil generator in the original diesel generator power supply site can be reused to save initial investment and operation and maintenance costs.
The controller in the series of all-in-one machines adopts a modular design and can be flexibly configured. The inverter output power has three powers, which can provide power supply for remote mountainous areas, pastoral areas, islands and communication base stations without commercial power supply. Help customers create the best social, economic and environmental benefits.
