Yunqida YQD-256150-LFOESS 3.5kWh Battery + 3.2kW Hybrid Inverter — All-In-One ESS
The Yunqida YQD-256150-LFOESS is a compact all-in-one energy storage system (ESS) that pairs a 3.5kWh LiFePO4 battery with a 3.2kW hybrid inverter. Unlike the larger 512-series units in the Yunqida range, this model runs on a 25.6V nominal battery platform, which keeps the unit smaller and lighter. As a result, it fits neatly into a single room, a small shop, or an SDU where floor and wall space are limited. Furthermore, the cabinet houses the battery, inverter, and BMS together as one factory-wired system, so an installer avoids matching separate components and can, therefore, commission the unit quickly — whether it’s going into a Kilimani bedsitter or a small kiosk in Kawangware.
Since Yunqida sizes the battery and inverter together rather than at the top of the range, this unit targets essential loads instead of whole-home backup. Consequently, it suits lighting, phone and laptop charging, a router, and a small fridge or TV through a typical KPLC outage, without the footprint or cost of a larger system. In other words, you get dependable coverage for the essentials, and, additionally, you avoid paying for capacity you’ll never use.
Key Features
- 3.5kWh battery capacity sized for essential loads during outages
- 3.2kW hybrid inverter supporting solar (PV), grid, and battery inputs on one unit
- Compact all-in-one cabinet that houses the inverter, battery, and BMS together for faster installation
- LiFePO4 (LFP) battery chemistry for long cycle life and stable thermal performance
- 25.6V nominal battery platform for a smaller, lighter footprint than higher-capacity Yunqida models

Note: The “platform standard” fields reflect specifications that Yunqida consistently documents across its 256-series LiFePO4 all-in-one ESS range. However, please confirm exact dimensions and weight against the unit’s printed nameplate at installation, since configuration-specific figures can vary by batch.
Who This Is Best Suited For
- Single-room tenants and small apartments in Nairobi who need lighting, charging, and Wi-Fi to stay on during outages without a bulky system
- Small shops and kiosks that only need to keep a fridge, POS device, and a few lights running through a blackout
- Landlords or SME owners equipping multiple small units with an affordable, space-saving backup solution per room or stall
