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.

"That builds an ecosystem when it comes to storage for the UK household." Boiron · APsystems · 01:18

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.

"I believe this product is going to be a great fit to social housing, providing operational efficiency to UK Installers." Boiron · APsystems · 02:51

Hello, very glad to welcome you at Solar & Storage UK in Birmingham this year in 2025. We are on AP System stand and I Maxime Boiron, Global Marketing Director of AP System. What we are seeing here is an AC-Coupled ESS system that includes charger and battery. So you got different options. You have single-phase charger like this one, a 5 kg in and out in terms of power. You got three-phase charger. This one is a 12 kg charger that works with three-phase grid. And you got to pair those charger with low-voltage battery. Here we are showing a 10 kWh low-voltage battery, but we have a range of 5 10 or 15 kWh battery. And you can put them in parallel to reach up to 160 kWh. So you can put actually up to 32 battery in parallel. So that builds an ecosystem when it comes to storage for the UK household. can work to maximize self-consumption. They can also be used as backup for certain appliance on the house. And you can even work them as an off-grid system. That's what we provide here together with of course our micro-inverters that pair with them on the roof. Whether those are multi-module micro-inverters on the three-phase side or dual micro-inverters on the single-phase side, depending on the circuit of the household. have the ability to monitor all of that on the monitoring system during the lifetime of the system. And we are making those systems more interoperable as well when comes to energy management systems so that it can run with HVAC products, EV charger and a lot of other solutions that we are now seeing penetrating UK households. What we are also introducing on the market here in the UK is the new QS2. It's a second-generation quad single-phase micro-inverter providing 2200 W AC output power and connecting four different high-power modules up to 600 W each. It has 4 MPPT, guaranteed up to 25 years and is backward compatible with our DS3 series. believe this product is going to be a great fit to social housing, providing operational efficiency to UK Installers. For further information, I invite you to go on our website ap-system.com, where you'll find useful resources such as video tutorials, webinar registration and a lot of documentation that will guide you through our solution.
