Hoymiles HiBattery 1920 AC
A 1.92 kWh LiFePO4 balcony battery that is AC-coupled and plugs into a normal socket, with 800 VA output, IP66 and a 10-year warranty.
- Best for balcony solar setups
- Plug-in battery
- 1.92 kWh
- IP66
- Made by Hoymiles.
- Capacity: 1.92 kWh LiFePO4, rated for at least 6,000 cycles.
- AC-coupled: it connects to a microinverter or a home socket and needs no change to an existing solar system.
- Output: 800 VA on the grid port and 800 VA (1,200 VA for 10 seconds) on the off-grid Schuko port; AC input up to 1,800 VA.
- Model: Hoymiles' site does not show an MS-A2. This page covers the HiBattery 1920 AC (HB-1920-AC-SV), Hoymiles' 1.92 kWh AC battery.

Specifications
Last checked on 11 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 1.92 kWh |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LiFePO4 |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | At least 6,000 cycles |
| ExpansionExtra battery units that add storage to the same system. | Not stated in the sources we read |
| Power | |
| AC output, grid-connectedThe lower output allowed when it feeds power into the home's circuits or the grid. | 800 VA nominal and maximum, single-phase, 230 V. Hoymiles says it can be customised to up to 2,000 VA in the S-Miles Home app |
| Backup outputA separate socket that keeps selected devices running when the grid is down. | Off-grid Schuko port: 800 VA, peak 1,200 VA for 10 seconds |
| AC charging inputHow fast it charges from a wall socket or the grid. | Up to 1,800 VA (7.83 A) |
| Charge and discharge powerHow fast the battery can take in and give out energy. It sets how many devices it can serve at once. | 1,000 VA nominal and maximum for the battery (charge and discharge) |
| Round-trip efficiencyThe share of the energy you put in that comes back out. The rest is lost as heat. | Up to 87% highest round-trip efficiency; 96.5% highest bidirectional efficiency |
| Solar | |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | None: AC-coupled, so solar comes in through a microinverter or the home circuit |
| Grid connectionThe supply type it is built for. Check it matches your home's supply. | Single-phase, 230 V, 50 Hz; grid compliance VDE-AR-N 4105:2018 |
| Connection and housing | |
| Dimensions (L × W × H)Check the space before you buy, including room around it for airflow and cables. | 460 × 240 × 203 mm |
| WeightMatters for lifting, wall mounting and moving it. | 24 kg |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP66 |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Charging and discharging from -20 to 55 °C; self-heating for low temperatures |
| Noise levelFan noise while working. | Below 17 dB(A), natural convection, no fan |
| ConnectivityHow you monitor and control it, usually through an app. | Bluetooth and 2.4 GHz Wi-Fi, LED indicator and app |
| CertificationsSafety and grid standards the maker says the product meets. | IEC 62477-1, IEC 62619, IEC 63056, UN 38.3, EN 61000 (EMC), VDE-AR-N 4105:2018 |
| Warranty | |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 10 years |
Compatible with
What Hoymiles says this product works with. Anything not listed here is not confirmed.
- Solar systems
- Hoymiles says it plugs into any socket and connects to a microinverter without changes to an existing solar system.
- Mounting
- Wall-mounted or floor-mounted (mounting accessories sold separately).
- Charging modes
- Self-consumption mode and time-of-use (TOU) mode.
Rules where you live
Rules for plug-in batteries differ by country. Hoymiles' datasheet describes plug-and-play use with a Schuko socket and lists German grid code VDE-AR-N 4105. It does not say whether a UK version or UK plug exists. In Great Britain, plug-in solar kits of up to 800 VA have been legal since 27 August 2026, but the rules exclude plug-in batteries.
Check the rules, incentives and tariffs for your own country in our country guides.
Strengths and things to check
Strengths
- AC-coupled: no change to an existing solar system
- Plug-and-play with a Schuko socket
- IP66 and fanless, below 17 dB(A)
- 10-year warranty and at least 6,000 cycles
- Self-heating for cold weather
Worth checking before you buy
- Only 1.92 kWh, and Hoymiles states no expansion option
- Whether it counts as a plug-in product depends on your country: check the rules below
- The datasheet shows a Schuko plug, which is not a British plug
- Heavy for a balcony unit at 24 kg
Change log
We record changes to this page here, so you can see when figures such as the warranty were last updated.
- 11 November 2026
- Page published. Warranty at publication: 10 years. Hoymiles' product list showed no Where to Buy link for this model. Figures are from datasheet REV1.1 (2025); Hoymiles also sells the larger HiBattery 4020 AC and 4020 X, which this page does not cover.
Where this information comes from
We have not tested the HiBattery 1920 AC. Every figure above comes from Hoymiles' datasheet for the HB-1920-AC-SV (REV1.1) and its product page, last checked on 11 November 2026. We found no product called MS-A2 on Hoymiles' website. A value these sources do not state is shown as not stated.
We do not show prices, because they change often and differ between sellers.

Common questions about Hoymiles HiBattery 1920 AC
Can I use the Hoymiles HiBattery 1920 AC as a plug-in battery in my country?
It depends on local rules. Hoymiles describes plug-and-play use with a Schuko socket. In Great Britain, plug-in solar kits up to 800 VA are legal since 27 August 2026 but the rules exclude plug-in batteries. Check our country guides.
Is there a Hoymiles MS-A2?
We found no product of that name on Hoymiles' website. The closest match is the HiBattery 1920 AC, a 1.92 kWh AC-coupled plug-and-play battery.
How much can the HiBattery 1920 AC store?
Hoymiles lists 1.92 kWh of LiFePO4 capacity with at least 6,000 cycles. The datasheet states no expansion option.
