Review on 🔌 Efficient EPEVER 40A MPPT Solar Charge Controller 12V 24V Auto - Maximize Renewable Energy Output with 40 Amp Negative Grounding, 100V Input, Lead-Acid and Lithium Battery Support, Load Timer Setting by Fort Steffen

This is my first review of the EPEVER Tracer 4210AN (May 14, 2018). I installed this controller on my 23ft RV trailer last month along with the MT50 remote display. I use it with two 100 watt Renogy panels and two series 24 batteries. I connected the panels in series and the 12 volt batteries in parallel. Although this is a very limited test of the system, I wanted to report my findings. I will update this review several times as we gain more experience with the system. I am VERY happy with the system. It exceeds my expectations for all conditions I've tried. In addition, the optics and workmanship of the system seem to be very good, especially for the price. Due to our many years of sailing activity, we are very economical in terms of electricity consumption. My typical daily budget is less than 40 Ah. This is mainly a water pump, refrigerator and water heater control circuits, lighting and phone charging. All lighting in our trailer is LED. In this situation, we only turn off 20 or 30 of our approximately 150 amp hours when the sun comes up (16%). I point this out because I was happy to see 7-8 amps at 8:30am. I've read reviews that spoke of disappointment with the poor performance of the amp and really wondered at the state of charge of their batteries at the time and the topology of their system. I've seen the 4210AN supply batteries with three times the power output of a PV array. That's why I chose the serial PV array configuration. Early in the morning with the sun low and clouds I still get results! I know the paragraph above is a bit wordy and covers many topics, but I think the topic is a bit more complex than many think. So my first impression of the 42110AN is that it's a great product for the price.
