my-PV hot water heating device DC ELWA 2kW

ELWA is a 2 kW photovoltaic hot water heating device and is perfect if you want to use your solar power exclusively to produce hot water. The direct current from photovoltaic modules is transferred directly to the built-in heating element and immediately converted into heat without loss. The built-in MPP tracker ensures that the PV generator is always operated at the optimal operating point, similar to a PV inverter.

No connection to the power grid is required to operate the ELWA, as the device is powered by the PV generator, i.e. pure island operation. The desired hot water temperature is set using a rotary knob and the LED displays provide information about the current device status.

• Easier and cheaper than thermal solar systems
• No need to go to the authorities: You save yourself the hassle of having to go to the authorities because our ELWA does not feed any electricity into the grid.
• Easiest installation thanks to "cables instead of pipes", contains less valuable copper, practically no maintenance costs.
• Shift charging possible with 2 devices
• Also works in the event of a power failure
• Hot water backup can be used optionally
• No frost protection necessary
• Cables have almost no energy losses compared to pipes
