Safety
Warning!
· If an external residual current device (RCD) (type A is recommended) is
mandatory, the switch must be triggered at a residual current of 300 mA
(recommended). RCD of other specifcations can also be used according to
local standard.
Ø PE Connection and Leakage Current
• All inverter’s incorporate a certified internal Residual Current Monitoring
(RCM) in order to protect against possible electrocution and fire hazard
in case of a malfunction in the PV array, cables or inverter.
There are 2 trip thresholds for the RCM as required for certification
(IEC 62109-2:2011).
The default value for electrocution protection is 30 mA, and for slow
rising current is 300 mA.
The islanding effect means that when the power grid is cut off, the
grid-connected power generation system fails to detect the power
outage and still supplies power to the power grid. This is very dangerous
for the maintenance personnel and the power grid on the transmission
line.
This inverter use active frequency offset method to prevent islanding
effect.
Ø Anti-lslanding Effect
High leakage Current!
Earth connection essential before connecting supply.
• A faulty ground connection can result in equipment failure, personal
and death injuries, and electromagnetic interference.
• Ensure correct according to grounding to IEC62109 and conductor
diameter according to STANDARD specification.
• Do not connect the grounding end of the equipment in series to
prevent multi-point grounding.
• Electrical appliances must be installed in accordance with the wiring
rules of each country.
This inverter should pair with high voltage battery, for the specifc
parameters such as battery type, nominal voltage and nominal capacity
etc., please refer to section 4.3.
Please refer to the matching battery specifcation for details.
Ø Battery Safety Instructions
For United Kingdom
