15KW Three Phase Distributed On-off Micro Grid System


1, The use of microcontroller and dedicated software, intelligent control;
2, The use of battery discharge rate characteristic correction accurate discharge control.
3, With over charge, over discharge, automatic control of electronic short circuit, overload protection, unique anti-reverse protection; more protection and it won’t damage any parts, and won’t burn the insurance;
4, The Use of a digital LED display and settings, this 4000w battery system for solar are design one-button operation to complete all set up, extremely easy to use and intuitive role is to control the entire system state, In the large temperature difference, the controller should have qualified temperature compensation function. Other additional features such as light control switch.
* More specifics and detailed product features or other custom feature, pls contact with our R&D department, those specifications are subject to communication.

Solar on Grid Topology Architecture

All loads’ power will be provided by our system, the unit will use battery storage to power the loads under premise of normal capacity. If PV electricity is more than the loads need at the same time by charged fully, it will feedback excess electricity to the Grid.

If the battery is low and the sunshine is bad, the system will firstly assure battery capacity is sufficient and use the grid electricity to power loads.
