2.2 Electrical system design
For safety reasons, the use of a DC switch is recommended. Between the
PV modules and the power modules may be mandatory in some countrie.
The selection of PV string output should be based on the optimum utilization of the invested capital compared to the
expected annual energy yield from the system. This optimization depends on local weather conditions and should be
considered in each individual case.
The inverter incorporates an input power limiting device, which automatically keeps the power at levels that are safe for the
inverter. The limitation depends mainly on internal and ambient temperatures. The limitation is calculated continuously and
always allows the maximum possible amount of energy to be produced.
Please use the tool supplied by Rayleigh Instruments when dimensioning a photovoltaic system.
