MYPV DC/AC ELWA USB Interface

ELWA uses DC power from PV panels directly for water heating. No grid connection, no inverter, and no need
for grid connection permits. Very easy to install. The patented ELWA system provides up to 50% of the annual hot water demand of a four persons household.
With a DC power of 2,5 kWp ELWA replaces a four to ten square meter solar thermal system. Automatic
AC backup heating ensures hot water supply during rainy days.
