EcoFlow PowerOcean DC-Fit

A PV-coupled retrofit battery solution like no other

Directly connect batteries with existing solar panels

Setting up an EcoFlow PowerOcean DC Fit is exceptionally easy compared to the conventional AC-coupled or DC-coupled systems. We directly connect the batteries to your current solar system on the PV side, without installing an additional storage inverter, or replacing the current solar inverter.

This efficient approach saves installation time and boosts the efficiency of your existing solar system.
