Like everyone else has mentioned, without using the provided adapter the polarity is reversed if you wire your solar positive and negative to it, to match red and black. You can use the provide adapter to correct this but I just wired it in reverse because the adapter is 2" long and I didn't want that much more sticking out and becoming a weak point over time. ### ⭐⭐⭐ Two different brands received *by R***S on Reviewed in the United States on August 16, 2021* Cables look sturdy, complete, will have to hook it up to the relevant panels first before increasing rating. But, ordered 4 with one seller, received two so far, those two were from different brands. ### ⭐ Reverse polarity wouldn't work *by N***H on Reviewed in the United States on September 7, 2020* The adapter would not work to plug my Renogy solar panel into my Zamp port on my travel trailer. I think it has to do with the way the polarity was set up. It seems to be backwards (even after using an adapter to "re-correct" the polarity, it still didn't work). --- ## 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/80599719-solar-adapter-compatible-with-mc4-connector-to-sae-adapter-cable](https://www.desertcart.co.uk/products/80599719-solar-adapter-compatible-with-mc4-connector-to-sae-adapter-cable) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
