Hoymiles HiBattery HB-1920-AC-SV AC storage 1920Wh LiFePO4

The HB-1920-AC-SV from Hoymiles (MPN: HB-1920-AC-SV) is a smart solution for storing and using solar energy in private homes. It is particularly suitable for balcony photovoltaic systems and scores points for its compact design, easy installation, and comprehensive safety features. Thanks to AC coupling, the device can be connected directly to any micro inverter or household outlet – without any modifications to the existing PV system.

Highlights of the HB-1920-AC-SV storage unit

• Compact plug-and-play design (0.02 m³): Installation takes just a few minutes, regardless of location. Its low weight and compact dimensions allow it to be used even in the smallest of spaces.
• AC coupling: Flexible connection directly via the Schuko socket – compatible with many common micro inverters and balcony power plants.
• Bidirectional charging/discharging technology: The system intelligently controls when energy is stored or discharged. The self-consumption mode prioritizes the use of your own solar power, while the AI-based TOU (time-of-use) mode automatically optimizes based on tariffs and typical consumption times.
• High efficiency: Up to 96.5% efficiency during charging and discharging, up to 87% round-trip efficiency – maximizing the usable energy generated.
• High-quality LiFePO4 battery cells (>6000 cycles): Independence and reliable long-term performance thanks to state-of-the-art cell technology.
• Self-heating: For safe operation even at low temperatures (down to –20°C charging/discharging), ideal for all seasons.
• Natural convection: Fanless design and low-noise operation (<17 dB[A]), resulting in low maintenance and versatile placement.
• Comprehensive safety features: Internal fire extinguisher, pressure relief valves, IP66 protection (dustproof and waterproof), all components designed for maximum operational safety.

Intuitive installation and flexible placement

Thanks to its compact design (0.02 m³ volume), the HiBattery can be used anywhere where space is limited—for example, on the balcony, indoors, or in the utility room. The plug-and-play configuration requires no changes to the existing PV system or special electrical installations: simply plug it into the socket, connect it, and it is ready for immediate use.

Intelligent energy management for maximum solar yield

The system uses bidirectional charging and discharging cycles. In self-consumption mode, as much solar power as possible is automatically supplied to the household and only surplus energy is stored in the battery. The AI-based TOU (time-of-use) mode takes electricity tariffs and consumption profiles into account – charging takes place at low rates and discharging is targeted at times of increased demand. This significantly increases the self-consumption rate and minimizes the purchase of expensive grid energy.

Safety in every application scenario

The housing complies with protection class IP66 and is therefore protected against dust and strong water jets – ideal for balconies and outdoor areas. An integrated fire extinguisher and pressure relief valves provide active protection even in extreme situations. The fanless design with natural convection ensures whisper-quiet operation (< 17 dB) without any wear-prone components.

How does the system stand out in everyday use?

The combination of plug-and-play use, quiet and maintenance-free technology, temperature tolerance, and comprehensive safety ensures maximum suitability for everyday use. All relevant protective functions are integrated ex works and do not need to be retrofitted. The storage unit can also be easily taken along and reused when moving house.
