ELWA is a 2 kW photovoltaic water heating device, perfectly suited for those who want to use their solar power exclusively for the production of hot water. The direct current from the photovoltaic modules is transmitted directly to the built-in heating element and immediately converted into heat without any loss. The integrated MPP tracker ensures that the PV generator always operates at the optimal working point, similar to a PV inverter. The ELWA operates independently of the power grid, as it is powered by the PV generator, making it a pure off-grid operation. A rotary knob allows you to set the desired hot water temperature, and the LED indicators provide information about the current device status. Schuko plug.
