APsystems’ latest QS2 microinverter model, an addition to its Quad series product, can deliver up to 2.2 kW single-phase output
The company also introduced its AHS-6.3 series Solar Battery Hybrid Controller, designed to operate in off-grid and backup mode
On the digitalization front, APsystems promoted its smart BESS AI model, APbot, and APdesigner, all blended with AI algorithms
APsystems, a Module-Level Power Electronics (MLPE) solution provider, with presence in microinverters, energy storage, and rapid shutdown devices, participated in SNEC 2025. During the show, it promoted its latest microinverter, solar battery hybrid controller, and advancement in artificial intelligence (AI) enabled digitalization.
Focusing on distributed generation (DG) scale PV applications, the company displayed its new Quad QS2 single-phase microinverter. It is a multi-channel product, featuring 4 MPPT channels in contrast to standard microinverters that connect with individual PV modules. Each channel supports a single PV module. This inverter is rated for an output power of up to 2.2 kW, indicating its compatibility with PV modules, each with a capacity of at least 550 W. The company emphasized that, regardless of partial or localized shading conditions, it can deliver module-level optimized output compared to a standard string-level counterpart. In terms of safety, it can restrict individual module's operational DC output voltage to below 60 V, mitigating any potential risk stemming from high voltages. In addition, its compatibility with other commercially available single-phase microinverters, such as DS3 and QS1, makes the system design flexible, says the company. For wireless communication between multiple QS2 models, it uses ZigBee communication protocol.
Beyond module-level microinverters, the company introduced its latest AHS-6.3 series Solar Battery Hybrid Controller. Designed to operate in off-grid or backup mode for both home and telecom applications, it supports lead acid or lithium-based batteries in 3 different voltage classes – 12 V, 24 V, and 48 V. Equipped with MPPT channels, it can deliver up to 6.3 kVA single-phase output. However, the company did not mention the number of integrated MPPT channels of the displayed product. While it operates in off-grid mode, during grid failure or shutdown, it switches to UPS mode in under 5 ms and provides backup power to emergency-connected loads.
Apart from new product launches, APsystems promoted its new smart digital energy management system, which is blended with AI. Empowered with historical energy generation data and consumption along with local energy prices, its BESS AI model enables charging or discharging schedules for balcony and residential storage systems. The company stated that this system enables smart and efficient energy use of different storage systems.
Furthermore, the latest APbot, built on an AI architecture, can improve customer interaction compared to its predecessor, says the company. Alongside the above-mentioned smart digital products, the AP Designer, a tool for PV design, is embedded with AI algorithms. This tool now offers image recognition, real-time simulation, and 3D modeling, according to the company.
