DC-coupled storage solution

 - Gain maximum value from PV plants with high DC:AC ratios
 - Reduce system cost and complexity
 - Add storage with no changes to the existing interconnection agreement
 - Achieve highest system and conversion efficiencies


REFU and Ampt have partnered to bring you an optimized DC-coupled storage solution that lowers system cost while maximizing production revenue throughout the PV system lifetime. This solution delivers the system cost and performance advantages of Ampt string optimizers along with the high-efficiency and wide operating range of REFUsol inverters. These components are controlled by the REFU HC-20 hybrid controller with advanced algorithms to create a flexible and optimized DC-coupled storage solution.

While each of these components are uniquely beneficial in PV systems, REFU and Ampt have partnered to provide customers with a DC-coupled storage solution that is designed to simplify the system installation and minimize the amount of hardware required.
Our solution gives system designers maximum design flexibility as the components can be either grouped centrally or distributed throughout the plant and allows them to add storage to already planned or installed systems without changing the AC characteristics of the PV system.
Our technology further enhances DC-coupled storage by providing a simple, cost-effective approach for both new and existing PV systems. With the joint REFU-Ampt solution, you will be a step ahead of other approaches available in the market today.
