ECOmulti installation Hub-2
A new photovoltaic system with storage has to be installed on a house. There is not plenty of room on
the roof, so a maximum of 12 solar modules could be installed. A few trees, the chimney and a

following program and firmware versions are used:
ECOmulti's AC output.
ECOmulti firmware 2610304
ColorControl GX rev. 1.14
VEConfigure 3 Rev. 90.04.169
The design regards the golden rule that generated solar energy has to be equal to the storage
batteries and the power of the ECOmulti:
