Detailed overview: Jackery SolarVault 3 Pro balcony solar battery with 4 MPPT and a built-in bidirectional inverter
The Jackery SolarVault 3 Pro is a balcony solar storage battery that stands out through its built-in 1200 W bidirectional inverter, rather than requiring a separate microinverter as with some competing DC-coupled systems. This design simplifies installation: panels connect directly to the unit, which handles conversion and output to the home network on its own.
Its 4 independent MPPT controllers each accept up to 1000 W, for a total solar input of 4000 W, with the option of adding AC coupling to capture extra energy from an existing rooftop solar setup already fitted with an inverter. Bidirectional AC output is factory-set to 800 W to comply with typical self-consumption regulations, with an uplift to 1200 W possible after installation by a qualified electrician.
Its 2520 Wh LiFePO4 battery is rated for 6000 charge cycles, and its capacity extends up to 15.12 kWh by adding up to 5 BP2500 expansion batteries, with the option to link several SolarVault 3 Pro units in parallel to reach 45.36 kWh in total. IP65 rated against water and dust, it includes a heating system that allows continuous operation from -20°C to 55°C.
Installation is designed to be plug-and-play, and control runs through the Jackery app over Wi-Fi and Bluetooth, with an AI mode that automatically optimises charge and discharge cycles based on electricity tariffs and weather forecasts. Backed by a 10-year warranty, for a stated lifespan of 15 years.

Comparison
How does the Jackery SolarVault 3 Pro compare with other plug-and-play balcony batteries, for searches like "best balcony battery with built-in inverter"? Here is how it stacks up against two references already in the catalogue: the Growatt NOAH 2000 and the Anker Solix Solarbank 3 E2700 Pro.
| Criterion | SolarVault 3 Pro | NOAH 2000 | Solarbank 3 E2700 Pro |
|---|---|---|---|
| Capacity | 2520 Wh | 2048 Wh | 2688 Wh |
| Inverter | 1200 W bidirectional, built in | Separate microinverter required | 800 W built in |
| Solar input | 4000 W (4 MPPT) | 1800 W (2 MPPT) | 1200 W (4 MPPT) |
| Expandable | 15.12 kWh | 8192 Wh | Up to 16 kWh |
| Observed price | ≈ €719 | ≈ €389 | ≈ £897 |
In short, the SolarVault 3 Pro stands out for its already built-in bidirectional inverter and wider 4-MPPT solar input, which simplifies installation compared with the NOAH 2000. The latter remains notably cheaper for anyone willing to manage a separate microinverter, while the Solarbank 3 Pro sits at a higher price point with a more limited solar input. For an all-in-one setup with the inverter already in place, the SolarVault 3 Pro is a solid option today.

Our tester's review: Julien De Jurquet
The SolarVault 3 Pro sets itself apart with a built-in bidirectional inverter: unlike other DC-coupled balcony batteries that need a separate microinverter, this unit handles charging and 1200 W AC output on its own. Its 4 independent MPPT controllers, each sized for roughly a 500 W panel, cope well with mismatched orientations and partial shading, a genuine plus for balcony setups with uneven exposure. Factory output is capped at 800 W to fit typical grid-tied regulations, with an uplift to 1200 W available through professional installation. Expansion via BP2500 batteries up to 15.12 kWh, or up to 45.36 kWh by linking several units, leaves real room to grow. Our main reservation concerns availability: at the time of writing, the product is actively on sale in France and Germany, but its rollout to other European markets, including the UK, is still imminent. For a first step into balcony storage with the inverter already built in, it is a solid option.
Frequently asked questions: Jackery SolarVault 3 Pro balcony solar battery with 4 MPPT and a built-in bidirectional inverter
No, the unit has its own 1200 W bidirectional inverter built in. Solar panels connect directly to its 4 MPPT inputs, with no additional microinverter to install.
That is the factory default setting, aligned with typical self-consumption regulations for installations without formal registration. Output can be raised to 1200 W after installation by a qualified electrician, subject to local regulations.
Yes, up to 5 BP2500 expansion batteries can be added to a single SolarVault 3 Pro unit, bringing capacity to 15.12 kWh. By linking up to 3 units in parallel with 15 expansion batteries, total capacity can reach 45.36 kWh.
Up to 4 panels spread across its 4 independent MPPT controllers, each sized for roughly 1000 W, for a total solar input of 4000 W.
At the time of writing, the SolarVault 3 Pro is actively on sale in France and Germany. Its launch in the UK is imminent, with a pre-order early bird campaign already under way and full sales expected from October 2026.
