1x Installation and operating instructions
The ELWA from my-PV (MPN: 12-0100) is a 2kW PV water heater that uses your generated solar power to produce hot water. The direct current from your PV modules is transferred directly to the heating element and immediately converted into heat without any loss. The built-in MPP tracker ensures that the PV generator always operates at its optimum operating point. A grid connection is not required, as the ELWA is supplied directly from the PV generator in stand-alone operation. The hot water temperature can be easily set using a rotary knob, while the LED indicators inform you of the current device status. Please consult an authorized specialist for installation, as certain standards must be observed during assembly.
How it works
ELWA uses direct current from solar modules to efficiently heat your hot water – no grid feed-in, no inverter, and no connection permits required. Installation is incredibly easy. With this system, you can cover up to 50% of the hot water needs of a two- to four-person household.The water heater replaces thermal solar systems with an area of four to ten square meters and works optimally with a photovoltaic output of up to 2.5 kWp. For a continuous hot water supply, it can also automatically switch to grid power if necessary.
