My solar panel puts out 12-21 volts. Will 21v damage the element?** A: The heater is actually two twelve volt elements connected in parallel by factory jumpers. Much of the time, this load would pull down a 300 watt panel to very low voltage resulting in poor heating. You will probably find the higher voltage and lower amps of putting the elements in series (change the factory jumpers) across your panel yields better results (heating) and solves the possibility of damaging the elements. The heater then becomes 24 V and 300 W. **Q: What is the resistance of the element aka how many ohms is it** A: The element which is made of sus304 has 0.48 ohms. Thank you **Q: what size bulkhead do folks use for this? Any links to one?** A: 12 volt 300 watt will take a long time to heat up i use a 48 volt 1000 watt element with batterys ## Frequently Bought Together - DERNORD 12V 700W Immersion Heater Submersible Water Heater Element Stainless Steel Heating Element with 1 Inch NPSM Fitting Double U Type - Beduan 1" Female Bulkhead Water Tank Connector Stainless Steel Thru-bulk Fitting - DERNORD 12V 600W Immersion Heater Submersible Water Heater Element Stainless Steel Heating Element with 1 Inch NPSM Fitting Double U Type --- ## 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.hr/products/490810470-dernord-12v-150w-immersion-heater-submersible-water-heater-element-stainless](https://www.desertcart.hr/products/490810470-dernord-12v-150w-immersion-heater-submersible-water-heater-element-stainless) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-19*
