Key Features
Supports two independent batteries.
Aggregates CAN signals to inverter.
Built-in LCD interface for protocol configuration.
Powered via 12V from inverter RS232 port.
Plug-and-play with 3x RJ45 ports.

Wiring Diagram
Connect the Sunsynk Klik as follows:
Step 1 | Connect the battery communication cable from battery 1 to the Sunsynk Klik battery port 2.

Step 2 | Connect the battery communication cable from battery 2 to the Sunsynk Klik battery port 3.

Step 3 | Connect the BMS/PCS communication cable to the Sunsynk Klik battery port 1.

Installation Instructions
Step 1 | Locate the inverter's RS232 communication port (Wi-Fi port).
Step 2 | Unscrew the inverter Wi-Fi port cover.
Step 3 | Plug the Sunsynk Klik into the Wi-Fi port.

Protocol Configuration
Upon powering up:

Step 1 | LCD will display BAT1 and BAT2 protocols.

Step 2 | Long press button 1 once to enter protocol selection mode for BAT1 (name flashes).

Step 3 | When BAT1 begins to flash, press button 1 to scroll through compatible protocols.

Step 4 | Once you have reached the protocol required, wait 5 seconds without pressing any buttons - setting will auto-save.

Set Battery Capacity
If the Sunsynk Klik does not show the correct combined SOC, it may be due the battery not sharing capacity information. Use this function to manually enter the battery capacity (Ah).

Step 1 | LCD will display BAT1 and BAT2 protocols.

Step 2 | Long press button 1 twice to enter BAT1 capacity.

Step 3 | If the display shows 0Ah, it means the battery does not share capacity information. Press buttons 1 or 2 to increase or decrease the capacity.

Step 4 | Once you have set the capacity, wait 5 seconds without pressing any buttons - setting will autosave.
