With a storage system, you don't waste any solar energy.

Hoymiles HiBattery AC Storage

The Hoymiles HiBattery AC It's more than just a battery – it's your personal energy storage system, as easy to use as a household appliance. Developed by Hoymiles, a leading microinverter manufacturer whose technology is already in use on over a million balconies, this storage system finally makes your energy independence complete.

Store the day's solar energy and use it whenever you need it: in the evening for cooking, at night for your appliances, or the next morning for your first coffee.

Simple & flexible: Smart AC coupling

Forget complicated installations, waiting for an electrician, or drilling holes in your walls. The Hoymiles HiBattery AC has radically simplified energy storage. The process is so simple that you can do it yourself in minutes: Unpack your storage unit, place it anywhere you like – on the balcony, in the basement, or even in the living room – and plug it into a standard household outlet.

The secret behind this simplicity is the intelligent AC couplingUnlike complex hybrid systems that require extensive rewiring directly at the solar modules, the HiBattery AC operates on the alternating current (AC) side of your household network.

Another special feature of the Hoymiles storage system is its universal compatibility and seamless integration with existing systems. No matter which balcony power plant or microinverter you already have, the HiBattery AC is the perfect upgrade. Digital setup is also incredibly easy: via Bluetooth and Wi-Fi, your storage system is connected to your network and ready to use in less than 60 seconds.

Maximize energy savings – with operating modes

A battery storage system only pays for itself if it helps you save real money and significantly reduces your dependence on the power grid. The Hoymiles HiBattery AC was designed precisely for this purpose and offers two intelligent operating modes that maximize your savings.

Saving while you sleep: The self-consumption mode

This is the core function of your storage system. During the day, when your balcony solar system produces more electricity than you consume, the HiBattery AC automatically recharges with up to 1,92 kWh of pure solar energy. Instead of feeding this surplus into the grid for a few cents, you store it for later. At night, when electricity prices are high, the storage system then supplies your base load appliances, such as the refrigerator, Wi-Fi router, and devices in standby mode, with your own free solar power. This intelligent energy reallocation alone can save you around €280 per year.

Outsmarting electricity prices: The time-use mode (TOU)

Your HiBattery AC works for you – even on rainy days or in winter. If you use a dynamic electricity tariff, your storage system becomes a smart financial tool. In time-of-use mode, it automatically charges when electricity is cheapest on the exchange, typically during the night. It then releases this cheaply purchased energy during the expensive peak demand times in the evening. This way, you avoid the highest electricity prices and use market fluctuations to your advantage. This strategy alone can save you an additional €70 per year.

Together, these two modes result in maximum annual savings of up to €350. This means your investment in the HiBattery AC can fully pay for itself in less than two years, granting you long-term financial freedom.

Technology: Performance and efficiency

Behind the simple operation of the HiBattery AC lies state-of-the-art technology designed to get the maximum out of every kilowatt hour.

Peak efficiency for maximum yield

Efficiency is the crucial measure of how much of the stored energy you can actually use in the end. The HiBattery AC shines here with industry-leading values: A bidirectional DC/AC efficiency of 96,5% and AC round-trip efficiency of 86% This ensures that hardly any energy is lost during conversion and storage. Every ray of sunshine captured by your modules is thus optimally utilized and converted into cash for you.

Expand storage capacity to up to 11,52 kWh

A Capacity of 1,92 kWh The HiBattery AC is ideally sized to cover the base load of a typical household overnight. This is the perfect start to energy independence. But your needs can change – perhaps you're planning an electric car or your family is growing. That's why the HiBattery AC is designed to be future-proof.

You don't have to invest in a huge system from the start. Start smartly with one module and expand your capacity whenever you're ready. You can up to six HiBattery AC units connect and your The total capacity can thus be expanded to an impressive 11,52 kWh.Your energy independence simply grows with you.

Safety first: Built for your home

When you install an energy system in your home, it must be absolutely safe. Hoymiles has implemented a multi-layered safety architecture in the HiBattery AC, based on the highest industry standards, guaranteeing you complete peace of mind.

Long-lasting & safe LFP cells

Prismatics operate inside the storage unit Lithium iron phosphate (LFP) cellsLFP is considered the safest and most stable lithium-ion chemistry, resistant to thermal runaway. These cells meet the stringent safety and durability requirements of the electric vehicle industry and are designed for over 6.000 charge and discharge cycles. A comprehensive 10-year warranty underscores this commitment to quality and protects your investment for the long term.

A multi-stage protective shield

We've thought of everything to protect your home. The security of the HiBattery AC is based on several interconnected layers:

The brain (BMS)The advanced battery management system (BMS) continuously monitors voltage, current, and temperature with 48 protection levels. It actively protects against overvoltage, overheating, short circuits, and other potential risks.
The Guardian (Dual MCU)A second, independent microcontroller (Dual MCU) acts as an additional safeguard. It constantly monitors the function of the main system and, in the unlikely event of a malfunction, can immediately interrupt the power supply – a double safeguard that is unique in this class of device.
Physical lifesaversFor emergencies, even physical safety mechanisms are integrated. An internal fire extinguisher and a pressure relief valve offer ultimate protection against unforeseen events.

Built for all weather

Whether indoors or outdoors, the HiBattery AC is equipped for any environment. Thanks to the IP66 protection rating It is completely dustproof and protected against powerful water jets – perfect for use on the balcony in all weather conditions. An integrated self-heating system also ensures reliable operation even in freezing temperatures. up to -20°CAnd so that he never disturbs your peace, he works with below 17 dB quieter than a whisper.

Intelligently measure and control yields

The HiBattery AC is more than just a passive energy storage device. It's an active and intelligent part of your home that adapts flexibly to your needs. Compared to its predecessor, the Hoymiles MS-A2, the HiBattery AC offers improved compatibility with electricity metering systems. While the MS-A2 often required a proprietary, less flexible solution, the HiBattery AC relies on open and intelligent networking.

Your system can now work directly with common smart home components to optimize energy flow in your home. This means the battery not only reacts intelligently to data from your inverter, but also monitors total household energy consumption in real time. This dynamic adjustment is made possible by direct compatibility with external devices.

For example, you can use Shelly Smart Plugs & Smartmeter or the Ecotracker from everHome to tell the HiBattery AC how much power your devices are currently using. The battery then precisely adjusts its output so that you draw as little power as possible from the public grid. This smart control ensures that your self-consumption is maximized and you reduce your electricity costs as effectively as possible.
