I really like the app this connects to via the Bluetooth dongle it gives loads for useful information. ### ⭐⭐⭐⭐⭐ Works well *by J***L on 9 February 2026* Works well ### ⭐⭐⭐⭐⭐ Feels well built *by D***N on 28 April 2023* Everything seems solid, the output graphics are a bit confusing, but, I kind of get it... lol! One bugbear, though the terminals are a good system, the screw heads are a little weak / poorly defined, it's quite easy for a screwdriver to skip, but, I guess a replacement screw the next time I take it apart... Won't be the end of the world! But seems fair to lose a star This is working in conjunction with my car's alternator and everything seems to work seamlessly, it's recognised both batteries and has seemingly improved the life of them both in parallel dramatically - presumably the mppt part coming in handy?! It seems to charge in very low light at 13v, however, I'm not sure how much of that is the technology of the solar panel or this charge controller, but, it seems to be the real deal! --- ## 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.ro/products/148808800-epever-40a-mppt-solar-charge-controller-12v-24v-auto-identification](https://www.desertcart.ro/products/148808800-epever-40a-mppt-solar-charge-controller-12v-24v-auto-identification) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-05-18*
