Offered for sale as it is no longer needed due to the introduction of a storage battery. Power Conditioner: SSI-TL40A8CS Color Display Unit: CMCS-03-B-W Connection Box: SCS-4CKT1 Operation was from around January 2017 to the end of July 2025. My home's solar panels are 4 kilowatts. It was working without any problems until it was removed. There is a crack in the hinge part of the connection box (Image 16). I am a layman, so I do not have the knowledge to answer questions, so please make your purchase based on the images only.
