Product Details

Meet Sol-Ark, the all-in-one hybrid solar power center that can handle anything you throw at it. Connect this 4.8 kW Sol-Ark + Fortress battery kit to the grid for an easy home battery backup solution. Or, install it as a fully independent system to deliver power to remote off-grid locations.

Not only does Sol-Ark’s cutting-edge hybrid inverter work in any solar application (grid-tie, off-grid, or battery backup systems), it can automatically detect connection to the grid and switch between on-grid and off-grid applications seamlessly.

This pre-designed solar kit contains the core components you need to go solar on your own terms, including solar panels, a power center, racking, batteries and battery enclosure. Whether you install your own solar panels or hire a local contractor to assemble your system, GoGreenSolar’s kits give enterprising DIYers a way to save money on their solar project vs. outsourcing it to a turnkey solar provider.
