DC110V Input 316 Heating Element Anti-Corrosion Electric for Household Hotel Use 3-Year Pressurized Solar PV Water Heater

Product Description

Solar Pv water heater it combines one or more PV panels with a storage water heater.

 

The OPTEN Solar PV Water Heater is a DC-powered water heating system that uses photovoltaic panels to directly drive a DC immersion heating element — no inverter, no energy-storage batteries required. This eliminates the two most expensive components of conventional solar electric systems, reducing total system cost by 40-60% while delivering reliable off-grid hot water.

Available in 60L, 80L, and 100L capacities, the OPTL Series is designed for households (2-6 persons), hotels, guesthouses, and RV applications. The system includes monocrystalline PV panel(s), an MPPT smart controller, a DC heating element, and a pressurized enamel-coated steel tank with 50mm polyurethane insulation.
