6.1 Safety
Danger to life due to lethal voltages!
High voltages which may cause electric shocks are present in the
conductive parts of the inverter. Prior to performing any work on the
inverter, disconnect the inverter on the AC and DC sides
WARNING
Danger of damage to electronic components due to electrostatic discharge.
Take appropriate ESD precautions when replacing and installing the
inverter.
6.2 Wiring AC Output
WARNING
You must install a separate single-phase circuit-breaker or other load
disconnection unit for each inverter in order to ensure that the inverter
can be safely disconnected under load.
NOTE
:The inverter has the function of detecting residual current and
protecting the inverter against residual current. If your inverter has to equip
a AC breaker which has the function of detecting residual current ,you must
choose a AC breaker with the rating residual current more than 300mA.
NOTICE
When using inverter with VDE-AR-N 4105, because the inverter's
displacement factor adjust function had to accorded to VDE-AR-N
4105,the PV-inverter system total capacity cannot be over 13.8KVA.
When using inverter with CEI 0-21: if the inverter system total capacity
more than3KW and up to 6KW,the displacement factor is adjustable
between 0.95leading to 0.95 lagging ,and not need the external SPI.if
the inverter system total capacity more than 6KW,,the displacement
factor is adjustable between 0.9leading to 0.9 lagging ,and need the
external SPI
。
You must install a separate single-phase circuit-breaker or other load disconnection
unit for each inverter in order to ensure that the inverter can be safely disconnected
under load.
We suggest you choice the AC breaker rating current in this table:
Growatt 7000MTL-S
40A/230V
Growatt 8000MTL-S
50A/230V
we recommend electrical connection as follows
