 Product Notes:

Installations with Sunsynk products now need to be registered here, (https://www.sunsynk.org/warranty), to gain full activation of the warranty.

Please ensure that you check that the Inverter is updated to the latest firmware version. For firmware updates, ensure that the inverter is on bypass mode and the PV is off. Failure to do this may damage your inverter.
