Anker SOLIX launched the SOLIX XE in the UK and Ireland, a residential energy storage system that integrates the battery, inverter, and battery management system (BMS) into a single architecture.
The proposal seeks to simplify the installation of home storage while using software to automatically adapt charge and discharge cycles to solar generation, household consumption, and electricity price variations.
The system starts with a capacity of 7 kWh and can be expanded via stackable modules up to 42 kWh. Additionally, up to three units can operate in parallel, bringing the total maximum capacity to 126 kWh.
For power conversion, 5, 6, and 8 kW versions are available, while the highest power model is designed to handle high single-phase domestic loads, including electric vehicle charging.
Anker SOLIX: A residential BESS designed as an integrated system
The XE architecture eliminates the need to separately install the inverter, battery, and BMS. This reduces external wiring and concentrates elements that are traditionally part of a modular installation into a single unit.
From an engineering standpoint, integration has a significant consequence: it decreases the number of interconnections required during installation and allows much of the configuration to be completed before the equipment reaches the site. Anker claims the system can be commissioned in approximately five minutes.
The storage unit uses 314 Ah LFP cells and is specified for up to 10,000 charge and discharge cycles, with a 10-year warranty. Lithium iron phosphate chemistry is widely used in stationary systems due to its stability and lifespan characteristics, which are particularly relevant when a battery must perform numerous cycles over years of operation.
Three MPPTs to better leverage solar generation
The XE incorporates three maximum power point trackers (MPPT) and supports up to 15 kW of solar input. This configuration allows for the independent management of different panel groups, a feature especially useful in homes where photovoltaic modules do not necessarily have the same orientation or tilt.
The importance of MPPTs is evident throughout the day. A roof may have panels facing different directions and receiving varying levels of irradiance.
By electrically separating the groups using multiple trackers, the system can seek the operating point that maximizes energy extraction from each set instead of treating the entire PV installation as a single homogeneous source.
The architecture is also prepared to perform two daily cycles. One possible strategy involves storing energy during solar generation hours and discharging during peak nighttime price periods. Subsequently, the battery can be recharged from the grid when rates are lower.
The battery begins to function as an energy operator
Here, one of the most interesting elements of the XE appears: Anker PowerOS uses AI-based energy management to coordinate the battery with household needs, PV generation, and electricity prices. According to Anker, the platform can connect with more than 870 European electricity providers.
This transforms the role of storage. The battery ceases to be merely a reservoir for storing solar electricity and begins to function as a manageable energy resource.
The software can determine when to conserve energy, when to use it to power domestic loads, and when to charge from the grid by taking advantage of lower-price periods.
The economic value of the system then depends on a combination of factors: energy capacity, available power, conversion efficiency, number of cycles, consumption profile, and tariff structure. AI does not create additional energy; it optimizes the timing of when available energy is used.
