by connecting six units in parallel
Midea Energy, the residential energy storage system (ESS) division of home appliance maker Midea Group, showcased the PowerNexus All-in-One and OmniX standalone ESS at Solar & Storage Live UK 2026.
The PowerNexus series features a built-in hybrid inverter and battery storage, and is available in single- and 3-phase configurations. The single-phase configuration is available in two power classes: 3-8 kW and 10-12 kW. The 3-8 kW variant uses 5 kWh battery packs, while the 10-12 kW variant uses 7 kWh battery packs. Both variants support up to 12 battery packs stacked vertically, for respective storage capacities of 5-60 kWh and 7-84 kWh.
The 3-8 kW variant is equipped with 2 or 3 MPPTs and supports a PV array range of 6 to 12.8 kW. The 10-12 kW variant features 4 MPPTs, supporting a PV capacity of 20 to 24 kW. Excess PV generation charges the battery, which can provide emergency backup during a grid outage. The ESS switches to backup mode within 10 ms of a grid outage.
The 3-phase ESS has a rated power output of 5 to 15 kW and a storage capacity of 5 to 60 kWh or 7 to 84 kWh. It has a maximum PV capacity of 30 kW with 2 MPPTs and a transition period to backup mode of <10 ms.
In comparison, the OmniX ESS connects a standalone hybrid inverter (nominal power output range of 15-30 kW) and an 84 kWh storage bank with external wiring. It uses 314 Ah and 7 kWh battery units for storage. This ESS features 3 MPPTs and supports up to 200% DC/AC oversizing of the respective full-load power output, with a maximum of 60 kW PV capacity. According to the company, its capacity can be expanded to up to 90-180 kW/ 504 kWh by connecting six units in parallel. It can be paired with the grid in an AC-coupled PV-plus-storage configuration as well as with a diesel generator via a dedicated port.
Midea Energy's sister company, Hiconics, also displayed the PowerInfi and PowerX1 residential ESS at the show.
TaiyangNews has recently published its "Balance of System (BoS) Components 2026" report, featuring inverters, storage and technology trends presented at SNEC and Intersolar Europe 2026.
