Yunqida YQD-5122002 11.78kWh Battery + 11kW Hybrid Inverter — All-In-One Stackable ESS
The Yunqida YQD-5122002 is the entry point into the 512-series stackable ESS lineup, pairing an 11.78kWh LiFePO4 battery with the same 11kW hybrid inverter used across the range. Because the inverter capacity matches the larger units in the family, this system can already handle demanding, high-draw appliances; however, its smaller battery keeps the upfront cost down for households and businesses that don’t yet need tens of kilowatt-hours of storage. The battery, inverter, and BMS ship together in one factory-wired cabinet, so installation stays quick and straightforward, whether the unit lands in a Kileleshwa apartment or a small workshop off Thika Road.
As with the rest of the 512-series, the YQD-5122002 is stackable. Therefore, it works well as a starting point: you can add battery capacity later as your power needs grow, without replacing the inverter or the existing unit. Given how often KPLC outages disrupt daily routines in Nairobi and upcountry areas alike, this makes the YQD-5122002 a practical way to begin backup power planning without overcommitting on day one.

Note: Fields marked “platform standard” reflect specifications that Yunqida consistently documents across its 512-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
- First-time backup power buyers who want a stackable system they can expand later rather than committing to a large capacity upfront
- Small households in Nairobi and upcountry towns running essential appliances (lighting, fridge, TV, router) through regular KPLC outages
- Small business owners — shops, salons, small offices — who need dependable power for POS systems, lighting, and light equipment without a large initial outlay
