Check that the
PV switch
is off.
Meet your grid operator connection conditions.
Risk of death due to dangerous voltages�
Do not connect the grid to the AC Output connector�
If the grid is connected to the AC Output connector, the anti-islanding protection
will not be ensured and the AC Output connector will not protect the user from the
dangerous voltages.
Connection is done by means of a 3-pole Wieland Gesis RST25i pluggable connector.
To connect the
CirPower Hyb
to the grid, follow these steps:
1�-
Before connecting the inverter to the grid, it must be checked that the insulation resistance
of the solar panels is above a certain limit, defined by the
EN62109-2
standard.
If the limit is not met, the inverter will show an alarm, and it will stay disconnected from the grid.
The standard specify that for ungrounded arrays, the insulation resistance must be than
R: : : 23.3 k
Ω
For the
CirPower Hyb
inverter,
V
MAx PV
: 700V
, so minimum insulation resistance must be
23.3kΩ
.
2�-
Check that the grid connection circuit breaker is switched off and signaled.
3�-
Check that the PV switch is off.
4�-
Check, at an accessible point, that the grid voltage is within inverter specifications.
5�-
Connect the grid cable, following the position marked at the connector plug. Cable outer
diameter must be 10 to 14mm, to guarantee IP protection of the connector.
Screws tightening torque :
0.8 ... 1 Nm.
