Tracer AN Series (40A) 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 40A 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
  • Advanced MPPT control algorithm to minimize the maximum power point loss rate and loss time

Hi. We are extremely happy with the purchase of the tracer controller purchased from Aussie batteries and solar. I just wish I had done it months before. Janet A

Charge controlled

Has served me well so far however the readout is a little confusing. Maybe a little more explanation in the manual would help with the battery level readings.

Awesome piece of kit

I've just built a stand-alone PV-battery-inverter system; totally separated from the house supply, and it is powering my laptop, radio and stand lamps right now. 1K PV (4 panels), 40A MPPT Tracer, 2 of 200AH gel batteries and 1kW Redarc sine inverter. Works like a dream. I think we need a blog site to share ideas on this topic.
