Pv Connection - Phocos Any-Grid Series User And Installation Manual

5. Make sure the six wires are securely connected.
CAUTION: Over-tightening the terminal screws can cause damage to the terminal, under-tightening
can cause a loose connection and excessive heat during operation, make sure to use the prescribed
torque. Ensure none of the conductor insulation is jammed between the terminal contacts.
CAUTION: Ensure the polarity is correct on all wires. Failure to do so may cause a short-circuit at the
AC source when several units are working in parallel operation.

PV Connection

WARNING: Before connecting the PV module array to the PV input of the Any-Grid, install an DC circuit
breaker between the Any-Grid and PV modules. This will ensure the inverter can be securely disconnected
during maintenance and is fully protected from over current of the PV modules. PV modules produce a
dangerous voltage even with little light. Make sure the breaker is open / off for the rest of the installation
procedure until instructed otherwise.
WARNING: Ensure the PV cables are sized according to the table below. Inadequate PV cables can cause
excessive heat or fire during operation.

PV Module Selection:
For selecting the correct PV module configuration, please consider the following points:

The total open circuit voltage (Uoc / Voc) of the PV module array may never exceed the values in the table
below. Consider the coldest possible temperatures at the location of installation together with the
temperature coefficient of the PV modules used.
 The total maximum power point voltage (Umpp / Vmpp) of the PV module array must be above the
minimum values in the table below. Consider the warmest PV module temperatures at the location of
installation.

The total maximum power point current (Impp / Ampp) of the PV module array may not exceed the value in
the table below.
