Easy Set Up: The integrated EcoFlow Power Hub has a simple plug-and-play design, allowing you to expand and customize your kit faster than any other power solution on the market. Save Space: EcoFlow Power Hub combines two MPPT solar charge controllers, one battery charger with MPPT, one DC-DC step-down converter, and an inverter-charger. With fewer modules and thinner wires, this 48V system saves you space and installation hassle. Charge Your Way: EcoFlow Power Kits support multiple charging methods. Get plenty of solar power, use your alternator, plug in shore power, or even use an EcoFlow Smart Generator for emergency charging.
