The REGO system combiner box is the "hub" for all REGO component connections, including lithium batteries, charge controller, DC-DC charger, and inverter. Uniform Anderson connections that simply click in, so no worries about special tools or complicated wiring, allow you to be ready for your off-the-grid adventures in minutes instead of hours, and put an end to the short circuits, misconnection, and connection failure. The integrated fuse switch disconnectors provide centralized circuit protection to your system devices. This allows for easy inspection and maintenance.

The continuous current rating of the system combiner box reaches 400A, able to handle high power charging and discharging. Engineered specifically for REGO batteries with 300A max charging current, and 350A max discharging current. Ensure battery performance and stability.
