I consult for remote solar powered systems on a budget. One thing to note is writing down how many amps you need from this controller as it will output 12V or 24V depending on your setup. I recommend 24VDC battery setups on this, 24VDC inverters, and it will then need solar panels that supply 24V+ to this controller. Its good to read all the instruction booklets for parts to see what its hookup requirements are and its min/max settings needed. ### ⭐⭐⭐⭐⭐ Great Affordable Controller that protects the system. *by on Reviewed in the United States August 5, 2025* Bought this over a month ago and has been working great ever since. I use it so far with one 250w solar panel charging 10 lithium 12v 40ah batteries at 24v. I ran the batteries in pairs of two in series/parallel. I use the off grid system to charge my electric motorcycle. So far I have not been plugged into my home ac power for a whole month. This controller is holding up just fine. ### ⭐ Menu won't open, No Voltage regulation during charging. Voltage too high. *by on Reviewed in the United States January 12, 2026* I set it up exactly as instructions directed. There was no control of the charging Voltage with the 60A charge controller. It appeared to "pass through" Solar Panel Voltage directly to the battery. Holding down the Menu button 3S did not open manual settings. There was no way to select the battery type. There were 15V being applied to the AGM battery. The unit emitted a smell of hot electronics. This could have killed my battery and or caused a fire. ## Frequently Bought Together - iSunergy MPPT Solar Charge Controller 40A 12V/24V Auto Solar Panel Intelligent Regulator with Dual USB Port LCD Display for Lead acid Batteries - 220W Solar Panel, 25.4% High Efficiency Monocrystalline with 10BB Hidden Busbar,MC4 Connectors, IP68 Waterproof for 12V/24V Off-Grid, RV, Boat, Cabin, Camping, Lightweight Outdoor Solar Power --- ## 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.ae/products/261648684-mppt-solar-charge-controller-40a-12v-24v-auto-solar-panel](https://www.desertcart.ae/products/261648684-mppt-solar-charge-controller-40a-12v-24v-auto-solar-panel) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-21*
