Solar panels
Before connecting the solar panels (also called photovoltaic
(PV) modules), you must check whether the voltage parameters
specified in the manufacturer’s data correspond with the actual
parameters. When checking the voltage please take into
account that solar modules supply a higher no-load voltage
when temperature is low and sunlight level remains unchanged.
At 4 °F ( -20 °C) the open-circuit voltage of the PV modules
must never exceed 1,000 V. The data sheet of the solar module
will include the temperature factors applicable for ascertaining
the theoretical open-circuit voltage at
4 °F ( -20 °C) . If the
solar modules exceed an open-circuit voltage of 1,000 V the PV
inverter might be damaged, which will void the warranty.
The PV inverter includes a residual current monitoring unit
(RCMU) according to VDE0126-1-1. This device measures the
ground current of the PV array and prevents the inverter from
feeding the grid in case of a ground fault.
■
Grid connection
Only appropriately licensed contractors are authorized to
connect the PV inverter to the grid. Consult your local
authorities for specific requirements. Before connecting the PV
inverter to the grid, permission for the connection must be
granted by the utility company.
