SINGLE PHASE HI 10/12kW | User Manual25
NOTE:
The grid power may still be present, but the inverter is not draining power from it since the unit is
working in ‘Island Mode’.
All neutrals can be linked together to maintain the neutral bond. When a Neural Earth bond is required for
an ‘O-grid’ operation, then it has to be removed on ‘Grid-Tied’ operation.
If an Earth Bond is required between neutral and earth and your system is a hybrid system, then you can
have a permanent earth wire since this can cause faults with an RCD before the inverter.
Since the inverter is a true hybrid, then the bond must only be made when the inverter is operating in
Islanding Mode. To accommodate this, Sunsynk provides an AC output, which is connected to the A/T/S
connections whenever the inverter is running on Island Mode. Therefore, you can simply connect the coil of
an AC relay to the ATS 240 connections. Next, you need to select Signal Island Mode on the battery charge
menu (click on the gear icon -> battery icon), as shown in the gure below.
