Solar panels are rated to a specific wattage in the best environment possible, but they will likely never achieve the written specifications on the panel/manual. Take note that in a typical 12V solar panel the output voltage typically ranges from 16V-18V, this is be cause you would need higher than 12V to charge a 12V battery and it is expected that the solar panels will not always get full sun. I believe best practice would be to get a charge controller and a small battery bank for your setup. You can get a decent charge controller for this setup for around $20-30 on Amazon. Batteries will vary, if you go with deep cycle make sure you have ventilation as they excrete flammable hydrogen gas, make sure you keep them filled with distilled water and have a cut off switch so they do not run under 40% charge. Running deep cycle batteries lose a lot of life if they are drained below 40% charge. You can also get lithium batteries that can be run all the way down to 0% without any difference in degeneration; however, with lithium batteries degeneration is occurs every time charging is initiated. With a solar panel and a charge controller you'll be constantly charging and discharging the battery. Good luck with your setup, sorry if this response inquires more questions than it provides answers. **Q: Can u run just one part of element for low demand and kick on the second part for higher demand** A: Of course you can, but please take down both metal plate. **Q: What the correct size of then ? Length and Width?** A: Please make sure your voltage and wattage(12V, 600W), and then take into account the length (Tube length to the terminal flange:180mm) and flange(1" NPSM). **Q: Hi, Can we run from 240v to 12v dc transformer directly?** A: Hi, 12v heating element is ok! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid. Good looking element. *by Z***O on July 29, 2019* Have not installed yet, but the product appears well made. Updates later. ### ⭐⭐⭐⭐⭐ Heats up quickly with proper power source *by C***. on November 27, 2021* Works as it should. Obviously, it'll heat up a smaller tank of water faster than a larger tank. ### ⭐⭐⭐⭐⭐ Five Stars *by M***. on February 14, 2018* Great price for a 600w 12v diversion hot water load. Solar power nuts take note. I noticed "as per chief" had problems. You can't run a 600w load directly on a 365w solar panel efficiently. It drags the panel voltage WAY down causing a massive load/source mismatch and you won't get but a tiny fraction of your available 365w solar panel power. Use 2 solar panels at 600-800w and a diversion regulator. Still, even an insulated covered 220 gallon hot tub is going to take time to heat up. Better yet use 2 of these 600w (1200w plus 18v reserve power) elements and 1500w of solar panels. A full blown solar power system with battery banks regulators etc smarter still. ## Frequently Bought Together - DERNORD 12V 600W Immersion Heater Submersible Water Heater Element Stainless Steel Heating Element with 1 Inch NPSM Fitting Double U Type - bayite DC 12V Fahrenheit Digital Temperature Controller 10A 1 Relay with NTC 10K Sensor - bayite BYT-7A006 DC 12V Solar Hot Water Heater Circulation Pump Low Noise 3M Discharge Head 2.1GPM --- ## 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.be/products/21709731-dernord-immersion-heater](https://www.desertcart.be/products/21709731-dernord-immersion-heater) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-25*
