Solar panels may make power at very high voltage and current. If all that is fed directly to the battery then it may get overcharged or blast (in extreme cases).A solar charge controller prevents this from happening. It is is placed in between the solar panels and the battery bank to regulate the charging current and voltage of the batteries through solar. It also prevents the reverse flow of current from batteries to the solar panels during night-time.Basically, without a charge controller it is not possible to safely use solar energy for charging batteries.

Solar Controller transform the solar energy into electricity power through the solar panel and stores,is widely used in mobile communication base stations,microwave stations,but also provide power supply for the pastoral areas,border,island units,and mobile occasions and so on.

The product is the new generation of intelligent solar charge and discharge controller, it has strong stability and high service life. This series is 12V/24V automatic identification, with automatic detection battery voltage function, pwm charging way and comprehensive protection function: overcharge, over-discharge, over-current, short-circuit, reversed.

The battery charging process of the JND-X controller is optimized to extend battery life and improve system performance.

Latest JND-X series PWM solar charge controller is used in solar off-grid system (independent system), especially suitable for small off-grid solar power generation control system, which automatically adjusts charging and discharging. The battery charging process of the JND-X controller is optimized to extend battery life and improve system performance.

The controller features a smart tracking algorithm inside that maximizes the energy from the solar PV module(s) and charge the battery. At the same time, the low voltage disconnect function (LVD) will prevent the battery from over discharging. Charging process has been optimized for long battery life and improved system performance. Meanwhile, the comprehensive self-diagnostics and electronic protection functions can prevent damage from installation or system faults.
