Our take on the 720 Watt Solar Panel Base Kit for Off Grid Backup Power

This is a 720 W off-grid solar panel kit built around six 120 W monocrystalline panels, with the wiring, a quick disconnect switch and a pre-wired 3-string combiner box included. It is a base or add-on kit, so you still supply the charge controller, batteries and inverter yourself. That makes it a fit for someone building or expanding a battery-based backup system who wants the panel side wired and ready. Against all-in-one solar kits it asks more planning, but it leaves you free to size the controller and battery bank to your own loads.
