This system provides backup functionality and off-board energy generation with a battery, suitable for portable or off-grid uses. For traditional residential installations, APsystems features the QT2 and QT2W microinverters, which can connect to between four and eight modules. These are complemented by a 10 kWh AC battery, which, according to Eberhard Löffler, Business Development Manager DACH at APsystems, can be retrofitted to existing systems and expanded up to 80 kWh.
High-Capacity Storage for Commercial & Industrial Applications
For commercial and industrial segments, APsystems showcases its 241L water-cooled AC battery. This system boasts a gross capacity of 241 kWh, with 217 kWh usable, and a 0.5 C-rate, enabling approximately 120-125 kW for both charging and discharging. Löffler explains that water-cooling ensures continuous operation by managing temperature extremes. The 241L is designed to retrofit existing AC-connected installations and can be multiplied for larger needs. APsystems also provides hybrid solutions that directly integrate with new PV plants, offering backup capabilities. For very large projects, they supply bankable container solutions up to two and five megawatts.
