sonnenBatterie 10 hybrid is a residential storage unit with lithium iron phosphate cells and a hybrid inverter included in the system. Capacity starts at 5.5 kWh and grows in 5.5 kWh steps up to 27.5 kWh by adding battery modules to the cabinet. It has an integrated backup power module: during a power outage it supplies only the selected appliances, not the whole home. It is compatible with Tigo Energy module optimizers. The grid connection is three-phase. Several units of this model cannot be connected together, so growth stops at 27.5 kWh.

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

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: 10000
warranty years: 3650

Power-to-capacity ratio 0.500 C

How we worked it out

continuous power: 2500
usable capacity: 5

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 grows from 5.5 to 27.5 kWh in 5.5 kWh steps by adding battery modules.
It is compatible with Tigo Energy module optimizers. source
The backup power module is already integrated: it doesn't need to be added separately.
It uses lithium iron phosphate cells.

Worth knowing

Backup power covers only the selected appliances, not the whole home.
Several units of this model cannot be connected together: growth stops at 27.5 kWh.
The grid connection is three-phase: with a single-phase supply it is worth checking with the installer first.
