Lensun® High Efficiency 40A MPPT 12V/24V Solar Panel Regulator Charge Controller LCD Display


Why we recommend buy MPPT Solar Controller?

   MPPT circuit solar controllers are considerably more elaborate than PWM. The MPPT technology to track the maximum power voltage point of solar panels as it varies depending on sunlight exposure and temperature.

   The voltage of the solar panel changes with time of day and temperature. The optimum voltage for battery charging changes as the state of charge of the battery. The MPPT charge controller matches these voltages and can result in 30% more efficient transfer of power. This means good MPPT solar charge controllers can reduce the number of solar panels needed by up to 30%- a tremendous benefit.

   Another benefit of MPPT technology is a wide solar input voltage range - this controller can work not only with standard off-grid 12V/24V solar panels, but also with on-grid panels or solar panel arrays up to 100V. The maximum allowed input solar power for this controller is 520W (when charging 12V battery) or 1040W (when charging 24V battery).

   This charge controller features a comprehensive set of electronic protection functions such as stopping reverse current at night (from the battery back to the solar panel), automatic cut off to prevent over-charging and deep discharge, solar panel over voltage, over load, short circuit and reverse polarity protection.

  Other features include dual timer function for load work, "dusk to dawn" settings, LED indicators, a temperature sensor for charging adjustment and RJ45 connection socket for a remote meter (can be purchased separately - have a look at our Remote meter / monitor for MPPT Tracer solar controllers).

  The controller can work with sealed, gel and flooded batteries and can automatically detect 12V/24V battery systems
