Fitted this to run the TV and the noise disappeared completely. ### ⭐⭐⭐⭐⭐ Perfect with the solar inverter *by on Reviewed in the United Kingdom 29 May 2023* This has fixed the problem with voltage spikes to my solar inverter. Now the voltage is a constant 13.6V and the inverter no longer cuts out when the sun shines brightly on the solar panel. The wires a could be longer and with lugs but overall very pleased. ### ⭐⭐⭐⭐⭐ Survived *by on Reviewed in the United Kingdom 10 August 2023* Not paying attention coupling to a 40volt battery and got the polarity wrong. Flash bang 5mm of wire vanished. Coupled correctly and to my surprise works perfectly 13.8vdc. You get a fare splash when you connect normally must be a big capacitor inside. ## Frequently Bought Together - HOMELYLIFE Voltage Converter DC 8V-40V to 13.8V 10A 138W Automatic Buck Boost Step Down Up Reducer Waterproof Module Transformer for Golf Cart Club Car - 2 Packs Power Wheel Adapter for Dewalt 20V Battery Adapter Power Wheels Battery Converter Kit with Fuses & Wire Terminals, 12AWG Wire, Power Connector for DIY Rc Car Toys, Robotics and Rc Truck --- ## 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.no/products/395702071-dc-voltage-reducer-automatic-buck-boost-converter-dc-8v-40v](https://www.desertcart.no/products/395702071-dc-voltage-reducer-automatic-buck-boost-converter-dc-8v-40v) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
