  • Page 7: Product Introduction

    2. PRODUCT INTRODUCTION The Sunsynk MAX is the most powerful low-voltage inverter in the world, achieving a maxium output power of 16kW and battery charge current of 300A. This power management tool allows the user to hit those ‘par- ity’ targets by managing power-flow from multiple sources such as solar, mains power (grid) and generators, and then effectively storing and releasing power as and when utilities require.

  • Page 24: Installing The Ct Coil

    4.10. Installing the CT Coil The CT coil is one of the most important parts of the Sunsynk Max. This device reduces the power of the inverter to prevent feeding power to the grid. This feature is also known as “Zero Export”.

  • Page 25: Earth Connection (Mandatory)

    Since the inverter is a true hybrid, then the bond must only be made when the inverter is operating in Island- ing Mode. To accommodate this, Sunsynk provides an AC output, which is connected to the A/T/S connec- tions whenever the inverter is running on Island Mode. Therefore, you can simply connect the coil of an AC relay to the ATS 240 connections.

  • Page 26: Meter Connection

The voltage displayed on the Sunsynk Parity Inverter will vary depending on whether the inverter is charging or discharging the batteries.

  • Page 44: Setting Up A Lithium Battery

    The batteries recommended for use with the Sunsynk systems are AGM Lead Acid or Lithium Battery Banks. (‘AGM’ means Absorbed Glass Matt construction that allows the electrolyte to be suspended new the plate’s active material. In theory, this enhances both the discharge and recharging efficiency. AGM batteries are very heavy as a result).
  • Page 45 PLEASE NOTE With some types of lithium battery, 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 bat- tery manufacturer specification.

  • Page 51: Grid Supply Page

    The power produced is supplying the ‘Non-Essential Load’ while the inverter is set at a maximum power of 8kW (Max Sell Power). The inverter is connected to the grid, but no export is performed. The unit allows small amounts of power to flow from the Grid (100W Zero Export Power) to prevent any back-flow. In this example, the solar PV is prioritised to supply the Load first and then subsequently, charge the battery.
