Ensure all circuit breakers are open / disabled before wiring the units so that there is no voltage on all battery, AC and
PV wires.
AC Input & Output Connections
Regarding AC input and output, please also follow the same principle. Use the wiring cross-section
and circuit breaker as defined for each individual unit, then attach those wires to bus bars. The bus bars from the AC
input are then connected to the AC source, the bus bars from the AC output are connected to the distribution panel
and loads.
Battery Connections
Make sure to use a separate DC fuse or circuit breaker for each unit. Instead of connecting each unit to the battery,
connect each positive battery cable to a bus bar, and each negative battery cable to a second bus bar. These bus bars
are then connected to the battery terminals. The cross-section of the bus bars, and the cables from the bus bars to the
battery terminals should equal the recommended battery cable cross-section per unit, times the number of units
connected to it.
All inverters must share the same battery bank. Otherwise, the inverters will go into fault mode.
Please install at least a breaker at the battery terminals and AC input of every individual Any -Grid
unit. This will ensure each unit can be securely disconnected during maintenance and fully protected from over-
current of battery or AC input. Use the breaker ratings as described in the chapters
“Battery Connection”
and
“AC Input
and AC Output Connection”
of the user manual.
