This document shows my practical experience in installing my first ECOmulti as a Hub2 system. The
following program and firmware versions are used:
ECOmulti firmware 2610304
ColorControl GX rev. 1.14
VEConfigure 3 Rev. 90.04.169
Scenario
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
dormer window creates partial shadows on the modules. The shading will degrade the overall
performance when a normal string inverter for all modules is used. For this solution 12 micro inverters
(Sunny Boy 240) are installed to enable individual MPPT tracking for each module. The micro inverters
generates 230VAC on their <font 14px line-height:
13.0666666030884px;/arial;;#000000;;#ffffff>paralleled</font> output, which is fed into one phase
of the houses mains supply. For self-consumption and storage a Victron ECOmulti is used on the same
phase. It is designed as a Hub2 installation, where the photovoltaic energy is applied on the
ECOmulti's AC output.
The design regards the golden rule that generated solar energy has to be equal to the storage
batteries and the power of the ECOmulti:
