Stacked Solar Battery System 5.12kWh LiFePO4 Module 5kW MPPT Inverter Expandable To 20.48kWh Wholesale Custom Branding For B2B Partners

Introducing the YF-EOH48-5.0U-S1, a modular stacked energy storage system that combines a high-performance LiFePO4 battery (5.12kWh, 51.2V, 100Ah) with a 5kW pure sine wave hybrid inverter featuring MPPT solar charging and AC grid charging. Its innovative stacked design allows you to start with one module and easily expand up to 20.48kWh (four modules) – no complex external cables, just simple stacking. Designed for residential solar self-consumption, backup power, and off-grid applications, this system is pre-wired and pre-tested to slash installation time. Backed by Yunfan Factory’s 13+ years of battery R&D, 60+ in-house engineers, and ISO9001/ISO14000 certifications, the YF-EOH48 series is your ideal private-label product for capturing the growing home energy storage market.
