Earth connection essential before connecting supply.
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 30mA, and for slow
rising current is 300mA.
• If an external RCD is required by local regulations, it is recommended to
choose a Type-A RCD with the rating residual current of 300 mA.

Beware of hot surface.
The inverter can become hot during operation. Avoid
contact during operation.
The inverter should pair with high voltage battery, for the specic
parameters such as battery type, nominal voltage and nominal
capacity etc., please refer to section 3.3.
Please refer to the matching battery specication for details.
For United Kingdom
