The ClearPOWER Solar Relay Box allows a homeowner to tie into a solar array panel to power the ClearPOWER P2. The relay system works with solar panels that have micro-inverters and/or optimizers that normally shut off during a power outage. It allows the solar panels to continue functioning bypassing the home's circuits and directly powering the ClearPOWER P2 and ClearPOWER C2. Ideal for homeowners who have already purchased and install solar arrays and now want to ensure they have access to their energy in the event of an emergency.
