If you need more energy storage than your Delta Pro offers, this is the way to upgrade.
It is as perfect for those with a smaller solar array on a tiny home as it is for people wanting extra work done on site before needing a recharge.
DELTA Pro’s Smart Extra Battery benefits from all the charging methods DELTA Pro has, including 6500W MultiCharge. That means you can charge anytime, anywhere as long as your extra battery is connected to DELTA Pro. Once connected, they’ll charge/discharge in unison, keeping the battery percent level across both units.
