My Pv ELWA, Photovoltaic Hot Water Unit, rated power DC 2000W, MPP

PRODUCT INFORMATION

ELWA is a 2 kW photovoltaic water heating device. 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 optimum operating point (similar to a PV inverter).

For operation, no connection to the mains is required as the unit is powered by the PV generator (pure off-grid operation). The desired DHW temperature is set with a rotary knob, LED displays inform about the current device status.

Your advantages with hot water from photovoltaics

• Easier and cheaper than thermal solar systems

• Each watt is utilized: Linear control from 0 to 2 kW, depending on PV yield.

• No grid operator approval required: You save yourself tedious administrative work, because ELWA does not feed electricity into the grid. Especially in multi-storey apartment projects, the approval can take several months for grid-connected PV systems.

• Easiest installation with "cables instead of pipes", less valuable copper, no maintenance costs.

• Stratification-heating possible with 2 devices.

• Even works in case of power failure.

• Boost-backup optionally usable.

• No anti-freezing liquid necessary

• Cables have almost no energy loss compared to pipes
