5.6. Available kits
The main kits that can be added to the various versions of the Ingecon® Sun Power Max.
5.6.1. Nighttime power supply
The control power of Ingecon® Sun Power Max inverters is fed from the PV array. Therefore, when the PV array has
no power, the inverter control turns off. In order to communicate with the unit at night, you have the option of ordering
the NIGHT POWER SUPPLY KIT, which feeds the inverter control from the mains.
To supply the inverter from the grid, an auxiliar supply of 230 Vac at 50/60 Hz must be supplied.
The kit comprises the power supply for the control (AAS0018) for each block.
When this kit is installed in the unit and powered by 230 Vac, the display will be operational, allowing users to navi-
gate through the menus and access the inverter via communications, but the inverter settings may not be changed
until the voltage of the PV array is within the MPPT range.
The number of power supplies must be the same as electronics power blocks.
5.6.2. 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 Power Max invert-
ers set up in the master-slave configuration.
The thermomagnetic circuit breaker 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 release 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.
