Jinpo 3kw off grid Solar Power System Controllers:
3kw photovoltaic controller

Solar energy charging and discharging controller is also called “photovoltaic controller”. Its function is to regulate and control the electric energy generated by solar cell module, to charge the battery to the maximum extent, and to protect the battery from overcharging. The role of over-discharge protection. In large temperature difference, photovoltaic controller should have the function of temperature compensation.
