Flex MPPT Supercharger

1 total reviews

If you need to boost your solar charging, you can add the Flex MPPT Supercharger upgrade, which allows you to add two more 90V strings of solar panels for a total of three 90V panel arrays for 90A (1,200W) of solar charge input. 

The Flex 1500 paired with 1 Flex Supercharger allows you to utilize a total of 12 storm or ascent solar panels (3 arrays of 4 panels). Doing this will allow you to recharge a single Flex battery in just 1.5hrs.

As you expand your Flex Modular System with additional Flex Batteries, you can also boost your system's solar charge rate to as much as 990A (4,400W). Please read below to learn how.

The MPPT Supercharger can be used only with a Flex 1500 or Flex DC Power Station.

Important Note: Will be back in stock soon.

    The Flex MPPT Supercharger includes two advanced maximum power point tracking (MPPT) charge controllers with up to 90V of solar charge input each, so it gives you more options and charges faster using solar panels—you can charge one Flex Battery from 0 to 100% in as little as an hour and a half in ideal sunlight. You will love the freedom of capturing clean, unlimited power from the sun whenever you need it.

      The Flex Modular Platform is designed to be completely plug and play. To connect the Flex MPPT Supercharger to the Flex 1500 or Flex DC Power Stations, simply add the Supercharger anywhere in your stack. The auto-lock system takes care of the rest. It takes only seconds to triple your system's solar charge rate. 


        For every Flex Battery you add to your system, you can also add another MPPT Supercharger to maintain a rapid charge time. If you added five Flex Batteries in pairs with five Flex MPPT Superchargers and additional solar panels, your entire 6,414Wh system could still charge in about an hour and a half.

        Before connecting six or more MPPT Superchargers, please consult with an Inergy Support Specialist at 877-891-2657.
