Set for photovoltaic water heating GETI GWH02D 2730W PV Trina

Product detailed description

Kit for easy installation of water heating in boilers and other installations.

The kit consists of 6 Trina monocrystalline panels ( 6x 04280478 ) with 455 W each, a GETI GWH02D 4000 W controller ( 1x 04291121 ) and a complete 25-meter cabling ( 25x 04290190 + 25x 04290189 ) with MC4 connectors ( 2x 03360241 + 2x 03360240 ).

Note: The GETI GWH 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 inverter is equipped with a large clear LED display, 3m temperature sensor and independent temperature setting for both PV and mains water heating. The GETI inverter also has a forced heating function. The inverter is compatible with most boilers on the market.

The system is simple , only requires the connection of the appropriate number of PV panels with a maximum output of 4000 W with an operating voltage of 160 ~ 350 V DC, a mains voltage of 230 C AC and the connection of a resistive load, such as a heater, electric boiler, electric radiator or underfloor heating and circuit breakers.

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

The maximum power of the system is 4 000 W. The inverter has a priority input from the photovoltaic panels and in case of a power shortage on these panels, the system is backed up with 230 V AC from the grid.
