Product Description

  • Uses a micro-controller and dedicated software, giving you intelligent control
  • Displays and records battery use and discharge rates, giving you accurate discharge control.
  • Provides and protects for over-charging and over-discharging, providing automatic control of electronic short circuits, offering overload protection, unique anti-reverse protection and more. It won’t damage any parts, and protects from surges.
  • Using a digital LED display and settings, this 4000w battery system for solar is designed with one-button operation to complete set up and to operate, making it extremely easy and intuitive to use.  For a large temperature differences, the controller should have a qualified temperature compensation function. Other additional features include a light control switch.

*All power demands can be provided by our system. The unit will use battery storage to power the loads under normal capacity. If provided electricity is more than your need and the battery is fully charged, it will feedback excess electricity to the Grid.

If the battery is low and sunshine is weak, the system will first check that battery capacity is sufficient, and then use the grid electricity to power loads.
