Selecting the Mounting Area This Hybrid Inverter is designed for outdoor use (IP65), 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.
Install the indoor unit on the wall where the floor height is higher than 1600mm. For proper heat dissipation, allow a clearance of approximately 500mm to the side, 500mm above and below the unit, and 1000mm to the front of the unit. WARNING For proper air circulation to dissipate heat, allow a clearance of approx.
Inverter Hanging Plate Installation Inverter hanging plate installation Battery Connection For safe operation and compliance, a separate DC over-current protector or disconnect device is required between the battery and the inverter. Switching devices may not be required in some applications, but over-current protectors are still required.

NOTE: When connecting more than one battery, ensure they are set in the configuration of ‘master and slave’. Depending on the battery type, the inverter should be capable of controlling the batteries BMS. Therefore, you need to set the protocol of the BMS on both the battery and the inverter. When using more than one battery, the first battery will be the master, and the other batteries will ...
Connecting the AC Before connecting to the grid, please install a separate AC breaker between the inverter and the grid. Also, it is recommended that installs an AC breaker between the backup load and inverter. This will ensure that the inverter can be securely disconnected during maintenance and fully protected from overcurrent. For the 3.6/5kW model, the recommended AC breaker for backup load is 40A.
PV Connection Before connecting to PV modules, please install a separate DC circuit breaker between the inverter and PV modules. It is very important for system safety and efficient operation to use appropriate cable for PV mod- ule connection. To reduce the risk of injury, please use the proper recommended cable size as below. Model Wire Size Cable (mm...

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.
The batteries recommended for use with the Sunsynk systems are AGM Lead Acid or Lithium Battery Banks. At its core, an AGM is still a lead-acid battery. AGM stands for Absorbent Glass Mat, which refers to the tech- nology these devices use to create power. This fiberglass mat sits between the positive and negative lead plates of your battery.
Page 44
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.

If nothing ticked: This Mode allows the hybrid inverter to sell back any excess power produced by the solar panels to the grid. If the use time is active, the battery energy can also be sold into the grid. The PV energy will be used to power the load and charge the battery, and then excess energy will flow to the grid.

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%.
Example: During 01:00-05:00, when the battery SOC is lower than 80%, it will use the grid to charge the battery until the battery SOC reaches 80%. During 05:00-08:00 and 08:00-10:00, when battery SOC is higher than 40%, the hybrid inverter will discharge the battery until the SOC reaches 40%.

Select the corresponding meter type according to the meter installed in the system. 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 paral- leled in a single phase utility grid is 16 and the maximum number that can be paralleled in a three phase utility grid is 15A.
Page 58
Each inverter will require a fuse isolator with surge protection and each group circuit will require an RCD. If the batteries as supplying power to the main load during the outage, then a change over switch will also be required or a split load can be used. The CT coils used to limit export power must only be connected to the master.

Most wind turbines are three-phase PM type. Therefore, either a wind turbine controller or a direct connec- tion 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 battery ( 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.
