Anker SOLIX Anker SOLIX BP3800 Expansion Battery
The short answer
Anker SOLIX lists this part for one power station on this site. Here is what they say.
What the maker says
Up to six BP3800 expansion batteries; capacity up to 26,880Wh | 'Expansion Batteries (3.84kWh each)'
These are the maker's exact words, copied from their own page. We do not reword them. That way you can see for yourself how strong the claim is. "Sold with this model" is a weaker claim than "works with this model".
Listed for these power stations
Listed for one model does not mean it fits another, even in the same family. Check your exact model before you buy.
Caveats recorded with this accessory
- Home Power Panel and transfer equipment require qualified installation.
- Model number NOT stated on this page. Batch 2 records the BP3800 relationship from the user guide; confirm the exact regional model before purchase.
