The Chinese company said that his new PV-driven boilers are in combination with grid electricity to guarantee a continuous household hot water supply. The new products depend on MPPT controllers and a digital control panel with programmable temperature settings and timer functions.
Chinese heating specialist Micoe presented two PV-driven boilers this week for residential use at the Intersolar South America 2025 event in São Paulo, Brazil.
“Our new PV boilers can be combined with grid electricity to guarantee a continuous hot water supply,” Bob Wan, the company’s sales manager, told PV -Magazine. “The systems can be DC-connected with solar panels and with AC-connected with the grid. A 500 W module can be sufficient to provide the smallest system in the series. The more solar panels you use, the more MPPTs are needed.”
The systems use MPPT controllers and a digital control panel with programmable temperature settings and timer functions. The manufacturer claims that they can reach an output temperature of up to 70 ° C (158 F).
The products are available in two versions: floors and wall mounted.
The underfloor heating is available in three sizes, with capacities of 150 L, 200 L and 300 L. Recommended input power varies from 10,240 to 13,650 BTU/H, with an MPPT work voltage range from 120 V to 340 V.
These systems have an AC rating voltage of 220 V and a temperature setting range from 55 ° C to 80 C (131 F to 176 F). The smallest model measures 520 mm x 1,190 mm, while the largest measures 630 mm x 1,476 mm.
The models mounted on the wall are available in two sizes, with capacities of 60 L and 80 L. Their DC input power is 1,880 BTU/H and AC-Rated power is 6,820 BTU/H, with an AC voltage of 220 V.
They also have a DC-rated power of 1,330 BTU/H and a DC-rated voltage of 42 V. The temperature setting range takes from 35 ° C to 65 C (95 F to 149 F). The smallest version measures 468 mm x 730 mm, while the largest measures 468 mm x 920 mm.
Micoe is located in the province of Lianyungang, the province of Jiangsu, China, where it also produces air source heat pumps, energy storage batteries, photovoltaic systems, kitchen appliances and water purifiers.
