Key Features


Tracer AN Series (20A) MPPT Charge Controller

Epever’s newly upgraded Tracer AN series with common negative earth is a high quality economically priced proper MPPT controller which features up to 99% tracing efficiency. The Tracer AN Series, MPPT charge controller with its 4-stage charging (Bulk, Absorption, Float and equalisation ), can substantially increase the life of your flooded, sealed,  AGM, Gel and Lithium-ion batteries. 

This MPPT controller has built-in protection against reverse polarity, over-discharging, over-charing, reverse current and overload along with protecting batteries from being overcharged by the solar array.   

The exterior of the unit is composed of die-cast aluminium for safe heat dissipation and general protection from wear and tear.

Tracer-AN 20A series charge controllers adopt MPPT (Maximum Power Point Tracking) technology. In any situation, it can Track the Maximum Power Point (MPP) of the solar array and obtain the maximum solar energy rapidly and accurately. It can generate up to 30% more power compared with the PWM charge controller. This series can accept max.100V Voc and work with the solar panels. The multifunction LCD display the system status vividly.


  • Advanced MPPT technology, with efficiency no less than 99.5%
  • Ultra-fast tracking speed and guaranteed tracking efficiency

20A Tracer MPPT Solar Charge Controller Regulator has a rating of 4.70/5 based on 10 reviews.

very reliable

Great controller ive lived on the 30amp one with 260 watts solar an 105 ah battery, I've been stunned at 5he difference this makes compared to a pwm controller of same specs almost double!!! 3 years later I'm very happy with it an about to buy a second 1 to expand my system, great for anyone looking for reliability an efficient power charging from only a few panels, 10/10 would recommend.

MPPT Controller.

Decided to go for the Maximum Power Point Tracking Controller to give my battery that bit more in the charging department. Time to test it out on that trip. Thanks Aussie Batteries and Solar.

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 .
