Double your capacity: Plans for using tons of energy off-grid? Link two DELTA Pro units and their battery management systems will distribute capacity evenly to anything plugged into this hub.
Even more output: House battery backup never had this much output. Chain two units together and your DELTA Pro’s will output a whopping 7200W, enough for even the most heavy-duty of appliances.
Portable & lightweight: The double voltage hub is easy to carry, and pairs with your DELTA Pro to bring even more versatility to your portable battery set up. Charge up, link your power stations and you’re good to go.
Three more outlets: The hub has two NEMA 6-20 outlets that power regular electronics as well as 20-amp power tools. It also has a NEMA L14-30 outlet, making it that much easier to switch out your old gas generator.
