Description

 How MY-PV AC-ELWA Solar PV Water Heater works?  The AC ELWA exclusively uses excess-energy from your PV-system and can be installed in hot-water boilers or storage tanks. The excess-power is determined with a digital electricity-meter which sends the control variable to the AC ELWA(s).

The MY-PV AC-ELWA Solar PV Water Heater controls its power linear, so that as little enery as possible is fed into the grid and that your self-consumption is increased significantly. Grid-connected PV-systems reach only 30% self-consumption on average. For a typical household with a 3 kWp PV-system the self-consumption can be raised up to 89%.

This solution replaces devices with thyristors, which are not allowed in accordance with the requirements of the grid operators in Austria and Germany for power ratings above 200VA. Stratification charge or synchronic charge possible for 6 AC ELWAs. The desired water-temperature can be adjusted with a knob.

Advantages of the MY-PV AC-ELWA Solar PV Water Heater

  • Linear power control 0 – 3.000W for maximum self-consumption
  • 3 – 18 kW power for each PV-system
  • Sinusoidal current consumption (no thyristor), grid compliant
  • Independent from the inverter
    with separate 3-phase electricity-meter PLA
  • Plug and play installation: no adjustment or programming required
  • Communication cable can be installed in normal AC cable channel
  • Hot-Water securing (Boost-Backup) included
  • Easy installation – perfect for retrofitting

System overview AC ELWA PV excess-management
One solution – many possibilities:

AC ELWA control with the PLA 3-phase-meter

The PLA 3-phase electricity-meter measures the energy flow of the house and determines the energy-excess. If excess is present, it activates the AC ELWA and transmits the value of the available power.
The AC ELWA transformers this excess PV-energy to heat.

  • A PLA can control up to 6 AC ELWAs for stratification charge or synchronic charge simultaneously.
  • PLUG and PLAY: no adjustment or programming required when the AC ELWA is connected to the PLA
  • Communication cable can be installed in normal AC cable channel
  • Wiring diagram

AC ELWA control with 0-10V via Universal Interface

AC ELWA control with 0-10V via Universal Interface

The AC ELWA can be controlled via the Universal Interface with 0-10V signals by third-party providers.

  • Several AC ELWAs can be controlled simultaneously

Note: A Connection to the PLA is not possible.

AC ELWA control with RS485 via Universal Interface

AC ELWA control with RS485 via Universal Interface

The AC ELWA can be controlled and requested via the Universal Interface with RS485 control commands.

  • Several AC ELWAs can be controlled and requested in bus-mode individually via their addresses
  • Status information and hot-water temperature can be requested
  • Integration in smart-homes

This solutions are not approved for the use with batteries!
