Description
The Sunwoda SunESS-5H is a high-voltage energy storage module from Sunwoda’s SunESS H series, tailored for residential or small commercial applications. Built using LiFePO₄ (LFP) chemistry, it provides a nominal capacity of 5 kWh and a stable high-voltage output (~400 V) thanks to a built-in DC-DC converter.
This high-voltage design reduces current losses and allows more efficient operation when paired with compatible high-voltage inverters. The operating voltage range of the module is 350 V to 450 V, making it very flexible for integration.
The SunESS-5H supports a rated charge/discharge power of 2.5 kW per module. With up to three modules in parallel, you can build a system capacity up to 15 kWh, or further scale if needed.
