Yunqida YQD-51210002 58.9kWh Battery + 11kW Hybrid Inverter — All-In-One Stackable ESS
The Yunqida YQD-51210002 sits at the top of the 512-series lineup, combining a 58.9kWh LiFePO4 battery with the same 11kW hybrid inverter used across smaller Yunqida ESS units. Because the battery scales up while the inverter stays fixed at 11kW, this configuration favours sustained runtime over raw output power — a good match for premises that need to keep multiple circuits alive for many hours rather than run a single high-draw appliance briefly. The battery, inverter, and BMS ship pre-wired in one cabinet, so installers skip the component-matching work that split systems usually require, whether the deployment sits in an industrial park off Enterprise Road or a lodge near Naivasha.
The unit carries the same stackable architecture as the rest of the range, so businesses can chain additional units together as demand rises instead of decommissioning the existing setup. With KPLC load-shedding sometimes stretching past a single day in parts of Nairobi and upcountry Kenya, 58.9kWh gives commercial sites enough headroom to run refrigeration, security systems, and office equipment simultaneously through an extended outage.

Note: Fields marked “platform standard” reflect specifications consistently documented across Yunqida’s 512-series LiFePO4 all-in-one ESS range. Please confirm exact dimensions and weight against the unit’s printed nameplate at installation, as configuration-specific figures can vary by batch.
Who This Is Best Suited For
- Commercial and industrial sites — warehouses, small factories, hotels — that need to run several circuits at once through long outages
- Multi-tenant or mixed-use buildings where backup power must cover shared systems (lifts, pumps, corridor lighting) alongside individual units
- Solar installers designing larger commercial ESS setups who need maximum capacity from the 512-series without upgrading inverter class
