The Sunsynk KLiK Dongle is a communication interface designed to solve one of the most common upgrade challenges in the field: expanding battery storage on legacy systems.
In real-world installations, battery models are frequently discontinued or replaced, leaving installers constrained by strict compatibility requirements between batteries and inverters. The KLiK removes this limitation entirely.
The KLiK acts as an intelligent BMS protocol translator and CAN signal aggregator. It allows two independent batteries—across different generations or even different brands—to communicate seamlessly with a single hybrid inverter. Instead of forcing system redesigns or full battery replacements, installers can now integrate newer batteries into existing systems without disrupting inverter communication.
At a system level, the KLiK:
This effectively unlocks cross-generation and mixed-brand battery expansion, a capability that has been traditionally restricted by rigid compatibility frameworks.
