If connected correctly (follow the instructions!) they work great. However, they seem to be very sensitive to whatever electrical disturbances occur during lightning strikes. I've had two of them fail and I believe it was because of lightning. Luckily, these controllers are relatively inexpensive. ### ⭐⭐⭐⭐⭐ Check your wiring! *by F***Y on Reviewed in the United States on December 15, 2016* Works Great, Watch out that all the Positive ends are tied together! ### ⭐⭐⭐⭐⭐ Five Stars *by A***R on Reviewed in the United States on May 29, 2017* Perfect! --- ## 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.co.uk/products/33147039-ehappymaker-20a-12v-24v-solar-battery-charge-regulator-solar-panel](https://www.desertcart.co.uk/products/33147039-ehappymaker-20a-12v-24v-solar-battery-charge-regulator-solar-panel) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-05*
