2. PRODUCT INTRODUCTION The Sunsynk Single-Phase Hybrid Inverter is a highly efficient power management tool that allows the user to hit those ‘parity’ 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.

4. INSTALLATION 4.1. Parts List Check the equipment before installation. Please make sure nothing is damaged in the package. You should have received the items in the following package: Hybrid Inverter | Installer Manual Page | 12...
4.2. Selecting the Mounting Area DO NOT install the inverter in the following areas: Areas with high salt content, such as the marine environment. It will deteriorate the metal parts and possibly lead to water/dampness penetrating the unit. Areas filled with mineral oil or containing splashed oil or steam such as found in kitchens. It will deteriorate plastic parts of the unit, causing those parts to fail or allow water/damp to penetrate the unit.
4.3. System Diagram ALSO CONSIDER: Installing the indoor unit, outdoor unit, power supply cable, transmission cable, and remote control cable at least 1 metre away from any television or radio receiver. This will prevent TV reception interference or radio noise. This will prevent radio signal interference from external units that might interfere with the Wi-Fi or GSM monitoring.

Risk of injury (Heavy Object) Remember that this inverter is heavy so users must be careful in handling the unit during installation especially when mounting or removing from a wall. Choose the recommend drill head(as shown in below pic) to drill 4 holes on the wall, 52-60mm deep.
4.6. Battery Connection For safe operation and compliance, a separate DC over-current protector or disconnect device is required between the battery and the inverter. In some applications, switching devices may not be required but over-current protectors are still required. Refer to the typical amperage in the table below for the required fuse or circuit breaker size.
All wiring/connecting must be performed by qualified personnel. Before making the final DC connection or closing the DC Breaker/disconnection device, ensure the inverter unit is wired correctly. A reverse-polarity connection on the battery will damage the inverter. 4.6.1. Recommended DC Battery Protection Grid Load RS485...
4.7. Connecting a Lithium Battery When connecting a Lithium battery, follow the connection steps below and check ‘Setting up a Lithium Battery’ to connect with an inverter. 1. Connect the correct diameter of cable in accordance with the battery manufacture specifi- cations along with recommended safety devices.
4.9. Connecting the AC Before connecting to grid, please install a separate AC breaker between inverter and grid. Also, it is recommended that installs an AC breaker between backup load and inverter.This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current.
4.10. Installing the CT Coil The CT coil is one of the most important parts of the Sunsynk Parity inverter. This device reduc- es the power of the inverter to prevent feeding power to the grid. This feature is also known as “Zero Export”.
Page 24
If the CT coil is fitted in the wrong way then this variable will have negative instead of positive val- ues when the power is flowing into the house/inverter. Also, the inverter export limiting function will not work properly. Hybrid Inverter | Installer Manual Page | 24...
Since the inverter is a true hybrid then the bond must only be made when the inverter is oper- ating in Islanding Mode. To accommodate this, Sunsynk provides an AC output, which is con- nected 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.

4.14. PV Connection Before connecting to PV panels, install a separate DC circuit breaker between the inverter and PV modules. In addition, we request users install PV junction box with surge protection to pro- tect the system from lightning strike. To avoid any malfunction, do not connect any PV modules with possible current leakage to the inverter.

Activating Shutdown causes the inverter to enter standby-mode. It does not com- pletely 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.

2. Check that the data cable is plugged into the correct sockets. Usually, RS485 is employed, but some battery manufacturers use others. 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 battery manufacturer specification.

When communications between battery and inverter does not exist, do not over- charge your battery bank (current or voltage). Many lithium batteries are limited to 100A, some are lower and some are higher. Ensure that voltage and current speci- fications provided by the battery manufacturer are followed. If you are using lead acid batteries then follow the equation of C x 0.25 which means that the maximum charge or discharge you can apply to a battery is a quarter of the AH rating of the overall battery array.

Example: This example shows the battery being charged up to 100% by both the Grid and Solar PV from 8 a.m. to 11 a.m. and then being able to supply up to 4kW of battery-power to the ‘essential’ loads from the ‘Load’ Port until the battery SOC drops to 50%.

Set the phase in which the inverter will be paralleled. Set the Modbus SN for paralleling. The Sunsynk parity inverter can be wired standalone or where more power is required it can be connected in parallel either single or 3 phase configuration. The maximum number of inverters that can be paralleled in a single phase utility grid is three and the maximum number that can be paralleled in a three phase utility grid is fifteen.
Page 63
For stability, all the batteries need to be connected in parallel. It is recommended a minimum cable size of 50mm diameter with fuse isolators to each inverter. Each invert will require a fuse isolator with surge protection and each group circuit will require an RCD.

Most wind turbines are three-phase PM type. Therefore, either a wind turbine controller or a direct connection to the MPPT via a simple protection circuit will be required. Dump Load or Diversion Load is an important part of an off-grid power system. When the bat- tery ( Battery Bank ) is fully charged, and the water turbine / wind turbine / solar PV module is still generating, a dump load is a useful device to send spare electricity to.

6. COMMISSIONING 6.1. Start-Up / Shutdown Procedure The inverter must be installed by a qualified / licensed electrical engineer in accordance to the countries wiring regulations. Before switching on, the installation engineer must have completed the Earth Bond, RCD and earth leakage tests, checked that the solar panel Voc voltage does not exceed 480V and checked the battery voltage.
6.2. Information for Commissioning the Inverter After you have successfully powered up the inverter, it must be programmed and set up as per the programming feature above. Check the VOC does Ensure both MPPTs Check each bond on not exceed 480V are balanced the solar panels If it falls out of the set-...
6.3. GDFI Fault Before the inverter connects to the Grid, it will detect the impedance (effective resistance) of the solar PV + to Ground, and the impedance of the solar PV - to ground. If any of the impedance values are less than 33kΩ, the inverter will not connect to the Grid and will report an error F24 on its LCD.
