5.6.1. Nighttime power supply kit
The control of the inverters feeds from the PV array. Therefore, when the PV array has no power, the inverter control
turns off. 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 and the necessary cabling for installing it.
