Review on 🔆 EPEVER MPPT Solar Charge Controller 40A - High Efficiency PV Solar Panel Controller with Remote Meter and Temperature Sensor by Lloyd Edwards

I recently upgraded my solar panels from 235W to 305W. My old controllers can't handle that much power so I bought this unit. Easy to set up and use with the MT-50 temperature probe and remote meter, my batteries stay charged and working great. Old charge controllers sometimes got very hot, but not this device. A large heatsink provides cooling. I wouldn't run it without the MT-50 remote as it gives a lot more information than flashing LEDs on the charge controller. It is important to note that you really need to read and understand the instructions on how this charge controller works. I have read many reviews about this charge controller and many of the reviewers do not understand what the charge controller does. I am satisfied with its performance. UPDATE: 6/26/2017 - I'm still impressed with this controller. I took him to my ranch in Colorado where he performed well and continues to work. By that I mean I usually lug my trailer (and all the solar gear) home after the Memorial Week hike. This year I left everyone in storage. I left everything plugged in hoping there wouldn't be any problems. Yesterday I checked the regulator at a friend's and swapped it. Everything works perfectly. Batteries discharge easily overnight, so it doesn't take long for the charge controller to shut off during the day after the batteries have been charged. It spends most of the day deriving energy from solar panels. My friend said that the fins on the controller are only warm and not hot. The controller reports that everything is OK. I am delighted that he is handling my holiday return so well next week on the 4th of July. UPDATE: 08/02/2017. As above, I connected my entire solar power system including this charge controller and left it fully functional. Now, in August, I checked the system again. It hasn't been touched since I left shortly after July 4th. It still works great! Here's what I set up: Two 305w solar panels in series. The panels are connected to the SolarEpic MPPT 40A solar charge controller with a voltage of approx. 75 volts. From the charge controller I have 4 Trojan batteries 6 volt T-105RE. The batteries are mounted in two pairs of 12V. The positive wire goes through a 40A fuse. Plus and minus are connected to opposite ends of the battery. This ensures that all batteries are fully charged. The wires going to my inverter are directly across from each other to evenly drain the batteries. It seems to be working very well. The inverter is a Ramsond SunRay 1500 Pure Sign Wave inverter. From there I go to a Kill-a-Watt meter to track wattage used, line voltage, etc. From the Kill-a-Watt meter, I go into a blown power strip. Using a 30A trailer adapter and a 15A plug, I connect my trailer to an extension cord. My caravan's headlights have been completely replaced with LEDs. Everything works in the caravan (TV, DVD, stove, fans) except for the air conditioning. The fridge and freezer in my caravan are 120v so they are also powered by the solar system. All of these items, with the exception of the solar panels, batteries and refrigerator, were purchased from Revain. With four T-105RE batteries I can work two days without sun. I am adding four more batteries for my next visit from September. I also switched from a Ramsond SunRay 1500 inverter to a Power Tech-On 3000W inverter. A larger inverter should run my microwave and maybe even my air conditioner (not that it's needed at 7000ft+ in Colorado). It will be another four weeks before I get back, but I expect the SolarEpic MPPT charge controller and all other hardware will continue to do the job as I planned. A note - I have two 36w bulbs on timers in my trailer. At night they turn on/off randomly. This will drain the batteries slightly for the next day's charge cycle. The wire used is 0/1 AWG on the 12V side. For solar panels I use 10 AWG, which I also bought from Revain. Overall, I'm very happy with how all of these parts work together to provide me with fully self-sufficient power. Do your homework, learn, and there's no reason you can't create a fully off-grid, reliable mesh. That's all for my last nursing home on the same lot which is over five miles from all utilities. See the image I added. This is my trailer home in Colorado, powered by my solar grid for almost two full months without intervention. My trailer has two 45w LED bulbs (Eq.) on timers. The lights go on and off all night. My security camera records the light in the morning just before I have the day off. Using flashlights will help divert some of the energy from the batteries, allowing the charge controller to do its job. The light is visible through the door window and front windshield of the trailer. Three more days and I'll be free again for the last week of the season. I learned with these controllers, make sure you plug them in properly, don't crank them to the max and they will work and work. The best controller I've ever bought. As expected, the controller continued to function and maintained optimal battery capacity. My new plan is to install two 305w panels and two 285w panels on the roof of my caravan. I will mount a charge controller and a full wave inverter in my trailer. The battery pack is in a battery box that I am building on the outside of the trailer. I plan to buy another one of these charge controllers. Last summer I lived with just two 305 watt panels all summer. Now when I add two 285W panels I have more than enough charge and power. I actually used the light function (load on/off) on the charge controller to turn on a 12v fan during the day and off at night, aimed at the controller to keep it cool. I've never had an overheating problem, but being away from camp for most of the summer wasn't something I wanted to risk. After all, there was more than enough power to charge the batteries and run the small fan, so why not. Great charge controller. https://youtu.be/IE3O9eQDGXQ
