Many of our customers upgrade their systems, and as a result may have a used inverter to offer, or perhaps some batteries with a few years left in them. Others may offer 12V appliances they no longer need, as they've switched to AC in their system. Some have used but good solar hot water panels. THIS PAGE IS FOR YOU!
