5.6.1. grounding kit

The PV array is grounded by a thermomagnetic circuit breaker that connects one pole of the PV array, negative or
positive, to ground. The polarity of the connection depends on the type of panel technology.
each MPPT can have only one ground reference, so this kit can only be installed on IngecOn Sun PowerMax
inverters with the master-slave option.

The thermomagnetic protection will open the PV array connection to ground when an insulation fault in the PV array
generates a current through the connection which is greater than the protection's tripping current.
The current generated by the panels is closed by the lack of a positive pole, closing via the negative pole connection,
until it returns to the panel. When the current exceeds the thermal value of the protection (10 A), the circuit is opened
and current ceases to flow to ground.
