Which is better?: Two 48v arrays in parallel or one 96v array?** A: First note, most panels labeled as "12V" will actually put out ~18V in ideal conditions. Knowing that, 4 of those panels at ~18V will create 72V when wired in series. Trying to do 8 panels in series will create near 150V (and open circuit voltage is often ~22V which could become 176V), so I'm pretty sure that forces you to just do the 4 panel groups to stay under the 150V limit. Also I hope you're doing 24V batteries with that many panels because that's way too much for 12V. These controllers take in all the power they can from the panels and convert the power to the battery charge power needed (which is part of the "Maximum power point tracking" feature). With the 8 panels sending in power like ~72V 10A, the controller accepts that and converts it to ~24V 30A (much like how a AC transformer works). If you were expecting it to go to 12V that much power would be ~60 amps at 12V that's well over the 40A rating. That's why they say "Max ~500 watts at 12V" while "Max 1000 watts at 24V" (and you can run the numbers yourself of 12V * 40A= 480W and 24V * 40A = 960W). **Q: Will this work for solar and wind turbine together ?** A: Hi, it works with solar panel ONLY. Not working with turbines. **Q: what are the minimum and maximum charge limit settings in the user mode? I would like to use a 6S lithium battery.** A: I’d buy a better charge controller like a MidNite Classic, these don’t last much more than 18 months and they are not as customizable as the Classic controllers are **Q: What is the PV operating voltage, minimum and max input voltage for 12 volt system.** A: From my experience with these charge controllers I have found that the low end cut off for operation is around 14 volts. I wired all my panels in series to get around 132 volts. Beware, the figure of 150 volts in the instruction manual is for minimum operating temperature, go with the other figure in the manual of 138 to be safe. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works like a Charm *by M***S on 5 January 2023* Keeps up with demands on battery and fully charge ### ⭐⭐⭐⭐⭐ Charge control controller *by A***N on 9 September 2025* Excellent charge controller for six gauge cable ### ⭐⭐⭐⭐⭐ Working like a champ. *by B***C on 9 June 2017* I recently upgraded my solar panels from 235 watt to 305 watt panels. My old controllers won't handle that power so I purchased this unit. Easy set up and use with the temp sensor and MT-50 remote meter keeps my batteries topped off and working great. The older charge controllers sometimes got very hot, but not this unit. The large heat sink keeps it cool. I wouldn't run it without the MT-50 remote as this provides much more information than the flashing LED's on the charge controller. It's important to note that you really need to read and understand the instructions on how this charge controller works. I've read a lot of reviews on this charge controller and in many, there's confusion by the reviewer as to what the charge controller is doing. I'm pleased with its performance. UPDATE: 6/26/2017 - I'm still impressed with this controller. I took it up to my ranch in Colorado where it performed perfectly, and continues to do so. What I mean by this is that typically I tow my travel trailer (and all solar equipment) back home after my Memorial week camping trip. This year i left all up at the camp. I left everything connected, hoping there would be no issues. Yesterday I had a friend check on the controller and inverted. Everything is working perfectly. There is little draw on the batteries over night so it doesn't take long before the charge controller is done for the day after topping off the batteries. It spends most of the day dissipating the energy from the solar panels. My friend said the fins on the controller were just warm but not hot. The controller is reporting everything is good. I'm very pleased it's doing such a good job for my return vacation this coming July 4th week. UPDATE: 8/2/2017 – Just as above I left my entire solar power system including this charge controller connected and fully operational. Now into August, I had a check made on the system again. It hasn’t been touched since I left shortly after July 4th. It’s still working perfectly! Here’s what I’ve got set up: Two 305 watt solar panels connected in series. The panels go into the SolarEpic MPPT 40A solar charge controller at about 75 volts. Out of the charge controller I go to 4 Trojan 6 volt T-105RE batteries. The batteries are set up into two 12v pairs. The positive lead goes through a 40A fuse. The positive and negative are connected to opposite ends of the battery bank. This provides a complete charge across all the batteries. The leads going to my inverter are on the exact opposite to discharge the batteries evenly. This seems to work very well. The inverter is a Ramsond SunRay 1500 Pure Sign Wave inverter. From there I go into a Kill-a-Watt meter to keep track of power used, line voltage..etc. Out of the Kill-a-Watt meter I go into a fused power strip. Using a 30amp travel trailer adapter to 15amp plug I plug in my travel trailer into the power strip. My travel trailer lights have been fully replaced with LED lights. Everything in the trailer runs (TV, DVD, furnace, fans) with the exception of the air conditioner. The refrigerator and freezer in my trailer are both 120v, so they also run off the solar power system. All these items with the exception of the solar panels, batteries, and refrigerator were purchased from Amazon. With the four T-105RE batteries I can run for two days with no sun. I’m adding four more batteries for my next visit starting in September. I’m also upgrading from the Ramsond SunRay 1500 inverter to Power Tech-On 3000 watt inverter. The larger inverter should run my microwave oven and possibly even start my A/C (not that it’s needed at 7000+ feet in Colorado). It’ll be another four weeks before I return, but I expect the SolarEpic MPPT charge controller and all the rest of the equipment to continue doing their job as I designed. One note – I do have two 36 watt light bulbs on timers in the trailer. They turn on/off randomly at night. This provides some drain on the batteries for the next day’s charging cycle. Wire used is 0/1 awg throughout on the 12v side. From the solar panels I’m running 10awg, also purchased from Amazon. Overall I’m very pleased with how all these parts are working together to provide me with fully off grid power. Do your homework, study, and there’s no reason you can’t create a fully off grid power system that is reliable. This is all for my final retirement home on the same property which is over five miles from any utility. See the picture I added. This is of my travel trailer in Colorado running on my solar power system now for almost two full months with absolutely no intervention. In my trailer I have two 45 watt(eq) LED bulbs on timers. The lights turn on and off throughout the night. My trail camera picks up the light in the morning just before shutting off for the day. The use of the lights helps to bleed some of the power from the batteries allowing the charge controller to do its job. The light can be seen coming through the door window and front window of the trailer. Just three more days and I'll be heading back up for my final week of the season. I've learned with these controllers, make sure you have them connected up correctly, don't push them to their max, and they run and run.... Best controller I've purchased yet. Just as expected, the controller continued to opperate and keep my batteries at the optimum capcity. My new plan is to mount two 305 watt and two 285 watt panels on the roof of my travel trailer. I'll mount the charge controller and my full sign wave inverter inside my trailer. The battery bank will in a battery box I'll build outside the trailer. I plan on purchasing one more of these charge controllers. Last summer I made it through the entire summer with just the two 305 watt panels. Now that I'm adding the two 285 watt panels I'll have more than enough re-charge capability and power. I actually used the light (load on/off) feature on the charge controller to turn a 12v fan on during the day and off at night, aimed at the controller to help keep it cool. I never had an overheating issue, but not being up at camp during most of the summer wasn't something I was willing to take a chance on. After all, there was more then enough energy created to charge the batteries and run the little fan, so why not. Great charge controller. https://youtu.be/IE3O9eQDGXQ ## Frequently Bought Together - EPEVER MPPT Solar Charge Controller 40A 150V PV Solar Panel Controller Negative Ground W/ MT50 Remote Meter for LiFePO4 Battery [Tracer4215BN] - Blue Sea Systems 5026 ST Blade Fuse Block 12 Circuit with Ground and Cover - T Tocas 50A Amp Circuit Breaker for Boat Trolling Motor Marine ATV Vehicles Stereo Audio Battery Solar System with Manual Reset Switcher 50 amp Waterproof DC 12V-48V --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/515803216-epever-mppt-solar-charge-controller-40a-150v-pv-solar-panel](https://www.desertcart.ec/products/515803216-epever-mppt-solar-charge-controller-40a-150v-pv-solar-panel) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-07-11*
