Details of an off grid PV system / Solar Home System with Inverter and DC loads
Abbildung: Steca GmbH
A small system for independent
power supply with solar energy typically consists of 6 components:
Of the solar
modules carry two cables A (+/-), dimensioned sufficiently large to avoid line
losses the charge controller B. The charge regulator should be at least 10%
higher dimensions, than the maximum
The battery cable
and the lines to the consumers should be protected with fuses.
Under no circumstances should the inverter be connected to the charge
controller, since it lead to the destruction
The inverter supplies 230 V AC consumers. The requirements for electrical installations are in the installation to be observed.
