APsystems Unveils Scalable AC-Coupled ESS and High-Power Quad Micro-Inverter
At Solar & Storage Live UK 2025 in Birmingham, Maxime Boiron, Global Marketing Director at APsystems, presents the company's latest solutions. The display features a scalable AC-Coupled Energy Storage System and the new QS2 quad single-phase micro-inverter. This sponsored content, part of EUPD Impulse's Innovation Hub, highlights products for UK residential applications.
APsystems' Scalable Energy Storage for UK Households
APsystems introduced its AC-Coupled ESS system, comprising charger and battery components. The system offers flexibility with both single-phase (5 kW in and out) and three-phase (12 kW) charger options. These chargers pair with low-voltage batteries, available in 5 kWh, 10 kWh, and 15 kWh capacities. The battery system is designed for scalability, allowing up to 32 batteries to be connected in parallel, achieving a total capacity of 160 kWh. This architecture supports applications such as maximizing self-consumption, providing backup power for household appliances, and enabling off-grid system functionality. The ESS is also being developed for interoperability with broader energy management systems, including HVAC products and EV chargers.

Introducing the High-Power QS2 Micro-Inverter
APsystems also presented the new QS2, a second-generation quad single-phase micro-inverter. This unit delivers 2200 W AC output power and is capable of connecting four individual high-power modules, each up to 600 W. The QS2 incorporates four Maximum Power Point Trackers (MPPTs) and comes with a 25-year warranty. It is also backward compatible with APsystems' DS3 series, simplifying integration for existing users. This product is positioned as a solution for social housing projects, offering operational efficiency advantages for UK installers.
