Sheet curated by JouleSpecs — We check every spec sheet against the manufacturer's own documentation: each value carries its source and the date we read it. Published Sept. 22, 2026 · Last updated Oct. 6, 2026 · Data verified Sept. 22, 2026

Jackery SolarVault 3 Pro Max AC is a lithium iron phosphate battery that connects to the home grid bidirectionally: it can both feed energy in and receive it. Toward the home it feeds in within the simplified threshold for plug-in systems; with verification by a licensed electrician and a request through the app it can go higher.

The battery expands by stacking up to five modules of the same type. If the grid fails it switches to the backup outlet within 20 ms: it is a backup function, not a professional UPS, and it does not switch in 0 ms. With only the internal battery, the backup outlet gives less power than with an external battery connected. Below 0 °C it activates battery pre-heating before charging. If the internet connection is poor, Bluetooth remains, showing real-time data but not the history.

The rest of the data comes from one page on the manufacturer's site, cited row by row in the table above.

A manual or a datasheet counts as a source even when the original file is hosted elsewhere: what matters is the document, not the server. Where that happens, it is stated above.

02 · The numbers

What it really costs

Cost per kWh 287.700 €/kWh midpoint of the estimated range — on nominal capacity

How we worked it out

price: 725
nominal capacity: 2.520

Battery life cycles 3650 cycles warranty years

the manufacturer does not state the guaranteed total energy throughput, which for heavy users is often the limit that runs out first

How we worked it out

stated cycles: 6000
warranty years: 3650

Cost of stored energy 0.079 €/kWh warranty years

the manufacturer does not state the guaranteed total energy throughput, which for heavy users is often the limit that runs out first
on nominal capacity: the manufacturer does not state the usable figure, so the real cost is higher
without conversion losses, which the manufacturer does not state: the real cost is higher

How we worked it out

price: 725
nominal capacity: 2.520
battery life cycles: 3650
round-trip efficiency: 100
energy delivered over the whole life: 9198

Energy density 98.800 Wh/kg

on nominal capacity: the manufacturer does not state the usable figure, so the true number is lower

How we worked it out

nominal capacity: 2.520
weight: 25.500

These numbers are calculated, not stated: they have no source to cite, they have a formula you can redo. The price used is the manufacturer's list price, which is stable and the same in every country — not a shop's price on the day.

03 · Summary

Pros and cons

In favour

It connects to the home grid bidirectionally: it feeds energy in and receives it.
It expands by stacking up to 5 batteries of the same type.
With a dynamic or custom tariff it optimizes energy use automatically: it draws from the grid when rates are low and feeds it back when rates are high.
Below 0 °C it activates battery pre-heating before charging it.

Worth knowing

It feeds into the home within the simplified threshold: going higher needs an electrician and a request through the app.
With only the internal battery, the backup outlet gives less power than with an external battery connected.
With a poor internet connection Bluetooth remains, which gives no access to the data history.
