aPower S

Direct Solar Connection, Maximum Energy Capture

The aPower S is a new-generation home energy solution that integrates formerly external inverter with battery storage into a single unit.

The fully integrated design allows direct solar connection, maximizing solar energy capture and storage. With high capacity and strong load-handling capabilities, it can power diverse home appliances, delivering reliable energy storage for whole-home backup and unrivaled energy freedom.

aPower S

Exceptional Solar Adaptability,
Unlock Full Solar Potential

The aPower S is designed for maximum solar compatibility, adapting to solar panels of all mainstream brands, various orientations, and tilt angles, unlocking the full solar potential in any scenario. Boasting high solar input support, the aPower S future-proofs system upgrades to higher power panels. The all-in-one design simplifies installation and reduces deployment time, perfect for current needs and future scaling.

Accommodate Large Solar Input

A single aPower S unit can access 20 kW solar panels, particularly ideal for large properties such as custom-built homes and small commercial buildings, making the most of the available roof space for solar generation and ensuring consistent maximum charging even when solar radiance is poor.

Accommodate Large Solar Input

Easy Access to Complex Solar Setups

Equipped with multiple solar input channels, the aPower S can access various independent solar arrays, particularly useful when panels are spread across different roof planes or buildings. Homeowners can also make investments in an incremental manner, starting from limited arrays and expanding as needed.

Preparing for Future Panel Upgrade

Each solar channel in the aPower S is deliberately designed with an input capacity2 higher than what most solar panels require. The extra capacity handles occasional solar energy surge, while also allowing for panel upgrades, allowing it to work with the next-generation solar modules with higher power rating.

Reliable and Long-Lasting Power Backup

Superior Operation Stability

Superior Operation Stability

The aPower S delivers UPS-grade3 power quality with instant response and ultra-stable power output, and is fully compatible with a broad range of household appliances, ensuring uninterrupted and reliable energy delivery at all times.
Meet Advanced Energy Needs

Meet Advanced Energy Needs

A single aPower S offers an industry leading 15 kWh of storage capacity, providing long-lasting whole-home backup. If your energy needs grow, the system can be scaled up to 15 units per aGate for 225 kWh of capacity, perfectly suited for large properties where there are a bunch of energy-intensive applications.
Rapid Charging

Rapid Charging

With up to 8 kW charging power, the aPower S stores energy rapidly, reaching full battery reserve in only 2 hours. It is always ready to power your home or handle unexpected outages.
Black Start — Automatic Energy Restoration

Black Start — Automatic Energy Restoration

Even during severe, multi-day outages when the battery is drained and the grid is still down, the aPower S can automatically be recharged using intelligent black start technology when the sun rises, resuming power to your home without manual intervention.

Higher Profit Potential

Higher Profit Potential

With an industry-leading 60 MWh warrantied throughput, the aPower S generates increased economic value for homeowners by enabling energy trade via virtual power plant (VPP) programs that earn you extra revenue.

Industry Highest Round-Trip Efficiency

The aPower S sets a new benchmark for round-trip efficiency (RTE)5 of up to 90.5%6 for residential energy storage. It minimizes energy waste and ensures more of your generated power is stored and available for use. This in turn translates to improved economic viability.
Optimized Energy Harvest from Solar

Optimized Energy Harvest from Solar

The solar input channels on each aPower S are managed by the proprietary Global MPPT7 algorithms that intelligently adjust to changing light conditions and maximize energy yield from every solar array for battery storage.
