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 ### ⭐⭐⭐⭐⭐ Charge control controller *by A***N on 9 September 2025* Excellent charge controller for six gauge cable ### ⭐⭐⭐⭐⭐ Works out of the box. *by A***R on 22 March 2020* User setup straight forward, see what is happening at a glance. ### ⭐⭐⭐⭐⭐ 100% Recommended by Off Gridder!! *by I***E on 22 July 2018* This is a good MPPT charger. I can set my own battery parameters using the MT50 monitor.Other off grid folks notice the same problem I used to have with my old chargers...a lot of times my old charger would go in float and shut my solar array off and I would be running things off my battery bank during sunlight hours!!! I have a large battery bank and have set absorb to 3 hours and would have set it for more hours because my batteries can be in absorbtion or boost charge for 12 hrs. I set my float charge up to 14.5 volts. I want my batteries charging as long as the panels can gather energy and I definitely do not want to be running off batteries before it is night time. I could not figure out what my earlier chargers were doing in float but they allowed my batteries to drain a little in afternoon and then kick back into charge mode when a preset low volt level was reached in float mode. This usually occurred right about the time the sun was setting so my batteries would not be at the maximum charge and surface charge as I headed to night time. Check your settings on your charger if you are off grid and your battery bank voltage at night. It took me a summer to figure out was going on and made me mad to find the sun was shining and I was running my home off the batteries instead of the panels!!! I love all my free daytime solar power..crank my freezer up full blast and charge up all my tools, phones, computers, run tools etc. After my batteries are full all the surplus electricity is free!! This Solar Epic has a 20 amp load outlet and shows the battery being charged and the load powered by your panels. Love the Solar Epic and have extra current and panels ( not over 130 volts) hooked to it so the charger is always getting max power to it. You can have more than 40 amps going into it but do not go over 130 volts. READ THE OWNERS MANUAL! UPDATE...unit is working great!!! The tracking seems to react quickly to passing clouds etc that some reviewers had complained was slow. I may buy another unit in the future. UPDATE.. I bought another of these Solar Epic chargers and added more panels. I have the MT52 remote for lithium batteries now and put MT52 remotes on both chargers. I have ten panels on each charger but keep the voltage way below the max of 150 volts...the excess amps are handled by the charger to a max of 40 amps. I also replaced my lead acid batteries with Eve 304 lipo4. Yahoo! I will probably be building bigger. I added a 43" TV and new freezer...off grid life is good with all this new technology and drastically lower price on panels and lithium cells! I already have a panel up with room for a couple more of these Solar Epic chargers. I noticed Will Prowse on YouTube had good things to say about this charger (I hope I am allowed to include this). I have electricity when the power is out! ## 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.at/products/177467451-epever-mppt-solar-charge-controller-40a-150v-pv-solar-panel](https://www.desertcart.at/products/177467451-epever-mppt-solar-charge-controller-40a-150v-pv-solar-panel) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-20*
