AC and Backup Load Connection Before connecting to the main grid, please install a separate AC Breaker (MCB) between the inverter and the grid. In addition, it is recommended the installation of an AC Breaker between the backup load and inverter. This will ensure the inverter can be disconnected safely during maintenance and fully protect the system from over-current.

NOTE: Only for South Africa – Using a permanent PE/N bond on LOAD OUTPUT is recommended, and the supply power to the grid port needs to be taken from the mains before the main RCD to prevent RCD from tripping. The bond we recommend being done in the external box clearly marked “permanent PE/N bond“, and this has been advised by local authorities.

Activating Shutdown causes the inverter to enter standby-mode. It does not entirely shut down the inverter. Total shutdown occurs at voltages below 19V. The voltage displayed on the Sunsynk Parity Inverter will vary depending on whether the inverter is charging or discharging the batteries.
State of Charge Bulk: The bulk charge is the first stage of a battery’s charging process, where the charger identifies the battery and its needs and then applies a high voltage to do the bulk of the charging. It involves about 80% of the recharge.
Page 48
NOTE: With some types of lithium batteries, the BMS cannot be controlled by the Sunsynk inverter. In this case, treat the battery as a lead-acid type and set the charging and discharging protocol following the battery manufacturer's specifications.

Program Charge & Discharge Times To set ‘Charge’ and ‘Discharge’ times, click on the ‘System Mode’ icon after clicking on the gear icon. What this page displays: 1. Use Export Controller: Tick this box to not export power back to the grid (the CT coil will detect power flowing back to the grid and will reduce the power of the inverter only to supply the local load).
Page 55
7. Grid peak shaving: When this is selected, the grid output power will be limited within the set value. If the load power exceeds the allowed value, it will take PV energy and stored battery energy to supplement. If there is not enough PV energy or stored energy to meet the load requirement, grid power will increase to meet the load needs.
Page 56
Zero Export to CT: The hybrid inverter supplies power not only to the backup loads but also to the household loads. If solar and battery power are insufficient, the grid will provide the necessary supplement, but no power will be exported to the grid. A CT is required for this mode. Please refer to the "CT Connection" section for installation instructions.
Page 57
Example 2: The solar power supplies non-essential loads while the inverter is set to a maximum power of 8 kW (Max Sell Power). Although the system is connected to the grid, no export occurs. To prevent reverse power flow, a small amount of grid power (100W Zero Export Power) is used.
