Solar inverter GETI GWH02D 4000W MPPT for PV water heating

Product detailed description

The GETI GWH02D solar inverter is particularly suitable for use in photovoltaic water heating systems using the NZU and NZU light subsidy programme (valid for CZ).

Save costs and heat water with solar energy today. Thanks to the GETI GWH02D solar inverter with automatic switching to the grid and the possibility to independently set the water temperature for heating from PV or AC, you can significantly reduce your hot water heating costs.

The GETI GWH02D 4000W MPPT inverter developed for PV water heating allows the direct use of PV panel systems to power resistance heating devices such as boilers, heaters, heating mats or heating coils. In addition, the inverter is also equipped with an AC input that allows the inverter to be connected to the mains voltage and heat water even when solar radiation is insufficient for heating.

The inverter is also equipped with a temperature sensor with a length of 3m and a separate temperature setting for heating water from the PV and AC mains. The GETI inverter is also compatible with most boilers on the market.

The GETI solar inverter is equipped with a circuit with switching relays that connect its output either to the inverter circuit or directly to the AC grid, so that it becomes only pass-through for the grid. The Geti inverter is thus only backed up by the grid (this is called bypass). Since the two power sources are separated in this way, it is not possible for the inverter to cause unauthorized flows to the grid.

Note: The GETI GWH inverter is only suitable for resistive loads with a bimetal thermostat (not suitable for electronically controlled thermostats!)
The inverter output (L, N) must not be connected to mains or earth! The inverter output must not be connected to a TN-C system.

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

The DC current generated in the panels, which cannot be fed directly to the heating devices, is converted in the inverter into AC current that can be used to power the heating devices.

The maximum output of the system is 4000 W. The inverter has a priority input from the photovoltaic panels and when this voltage drops below 120V, the water heating will be supplied from the 230V AC mains voltage.
