GETI Regulator GWH02D for photovoltaic water heating, 4kW, used

The exhibition device is tested and fully functional. The device looks like new, it only has punctured grommets from the connected cables. We sell it as used with a full 24-month warranty.

The GETI GWH02D 4000 W MPPT inverter allows for direct use of photovoltaic panel systems to power resistive heating devices such as electric boilers, heaters, heating mats, water heaters, etc. Additionally, the inverter is equipped with an AC input, which allows the inverter to be connected to the mains voltage and heat water even when solar radiation is insufficient for heating.

The system is simple, requiring only the connection of the appropriate number of photovoltaic panels with a max. power of 4000 W and an operating voltage of 160 ~ 350 V DC, mains voltage of 230C AC, and connection to a resistive load, e.g., heating coil, electric boiler, electric radiator, or underfloor heating.

The direct current generated in the panels, which cannot be fed directly into heating devices, is converted into alternating current in the inverter, which can be used to power heating devices. The inverter has a priority input from the photovoltaic panels, and if this voltage drops below 120 V, the water heating will be powered from the mains voltage of 230 V AC.
