2-in-1 Electric Water Heater Element for Solar System and Grid
Heat water using DC 48V solar energy or AC 220V grid power, all in one device. The ideal solution for reducing energy costs and leveraging existing photovoltaic panels. Compatible with most standard water heaters, it ensures continuous hot water supply regardless of weather conditions.
What you get with this product
- Energy bill savings by automatically prioritizing the DC 48V 500W solar source
- Uninterrupted operation ensured by AC 220V 1000W grid backup power
- Complete overheating protection with 2 safety thermostats calibrated to 85 degrees Celsius
- Simple installation in the existing water heater without major plumbing modifications
- Compatibility with off-grid and on-grid photovoltaic systems for maximum flexibility
- Robust construction with silicone gasket and extended connection cables for easy mounting
How it works and how to install
The heating element has two independent circuits: one connected to the DC 48V solar system, which operates preferentially during the day, and one connected to the AC 220V grid, which automatically takes over when solar energy is insufficient. Integrated thermostats automatically stop heating at 85 degrees for maximum safety.
Installation is done by replacing the old heating element in the water heater, connecting the distinctly marked cables for DC and AC, and testing the functionality of both sources. It does not require advanced electrical skills, only respecting the polarity for the DC connection and the phase for AC.
Frequently Asked Questions
Can I use this heating element with 12V or 24V solar panels?
No, the heating element is strictly designed for DC 48V systems. For other voltages, you will need a suitable DC-DC converter or a heating element compatible with your system's voltage.
How long does it take to heat a 100-liter water heater?
With 500W DC solar power, approximately 4-5 hours to reach 60 degrees Celsius. With 1000W AC grid power, the time is reduced by half, about 2-2.5 hours, depending on the initial water temperature.
What happens if both sources are connected simultaneously?
The heating element functions correctly with both sources permanently connected. The system will preferentially use available solar energy, and the AC grid will supplement or take over when necessary, without risk of overload.
