EPSOLAR Tracer series controller 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.
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.

40A Tracer MPPT Solar Charge Controller Regulator has a rating of 2.75/5 based on 4 reviews.
I installed my 40a tracer on my Winnebago with 1100watts of solar.....used a sealed deep cycle lead acid 145ah battery...... Followed the presets for boost at 14.4v and thought my battery was dying... Found some site recommending 14.6 to 14.8v boost so I went to user parameter and seti things to a higher boost voltage and got good results..... 14.6v would have been far too high for flooded lead acid but that's what these new sealed batteries like,Frank on 11 November 2018
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.Mr Paul F on 27 June 2018
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.David B on 12 January 2018
looks the part
You have timed this badly as I am currently waiting for a recharge from a full discharge and it is now the third day. I will admit that it is only early on the third day and sunshine was scarce yesterday however the first day was full sunshine all day with 500W of solar panels how come I only gained 20%Mr Paul F on 17 March 2017
