MPPT Solar Controller EPSOLAR Tracer Series 20A

This Solar Regulator adopts MPPT technology (Maximum Power Point Tracking). This advanced tracking algorithm makes the solar module operate at an ideal voltage where the solar modules can produce the maximum available power. Compared to conventional PWM controllers, MPPT technology increases the charge efficiency by up to 30% and decreases the power of solar array needed. It can also accuratley track the MPP point in any situation which will improve energy efficiency and obtain  maximum solar energy.

The regulator has the ability to step-down the higher voltage solar array to recharge a lower voltage battery bank. This allows on grid solar modules or thin film modules to charge the off-grid battery, and the cable size can be reduced because of the small current from the solar array.  Based on common positive design and advanced MPPT control algorithm, with LCD  displaying running status, this product is artistic, economical and practical.

EPSOLAR Tracer Series 20A Features:

  • Advanced MPPT technology
  • High tracking efficiency no less than 99.5%
  • Peak conversion efficiency of 98%
  • Ultra-fast tracking speed
  • Accurately recognizing and tracking of multiple power point

  • Battery reverse polarity protection
  • Load short circuit protection
  • Controller overheating protection

Maximum power point tracking solar charge controller for off-grid & remote power solutions. With MPPT control algorithm, in any situation, this product can fast and accurately track out the best maximum power point (MPP) of photovoltaic array, in order to obtain the maximum solar energy in time, which remarkably improves energy efficiency.


20A Tracer MPPT Solar Charge Controller Regulator has a rating of 4.63/5 based on 8 reviews.

Good quality regulator

Have 3 of the 20 amp models very good units easy to in stall and easy to setup one in my RV set up on a 340 amp lithium battery and a 250 watt panel One in the RV shed on 2 agm 130 batteries also on 250 watt panel and a third will be set up on my RV car trailer for added boost for the RV when in tow also on a 250 watt panel. Would recommend to anyone how would like good reliable solar system .
