## At a glance

- Designed to stack with a Solarbank 4 Pro system, with the listing claiming expansion by up to five BP5000 modules.
- The page describes each module as 5kWh and the expanded system as up to 30kWh.
- The listing claims IP66 dust and water resistance and operation from -20°C to 55°C.

## Pros

- Stackable design allows capacity expansion within the stated Solarbank system compatibility.
- The listing gives installation temperature and IP ratings, useful when planning an outdoor location.

## Cons

## Before you buy

- The listing is inconsistent about system capacity: one feature says scaling from 5kWh to 3kWh, while another states five 5kWh modules can bring the system to 30kWh. It also gives two dimension sets, and the title names Solarbank 4 Pro while the detailed compatibility text calls it Solarbank 4 E5000 Pro. Confirm the intended battery, system compatibility and dimensions before purchase. Installation or removal requires the system to be completely powered off with PV and AC inputs disconnected. The listing says two people should carry the 42 kg battery.

## Less suited to

- Anyone seeking a portable battery or a product for carrying frequently.
- Buyers who need a clearly consistent capacity and dimension specification without further confirmation.

## Customer feedback

The page provides aggregate ratings but no customer-review summary. The ratings are mostly five-star, with some lower-star ratings, but they do not establish what buyers liked or disliked. They cannot resolve the listing's conflicting capacity, compatibility and dimension details, which matter when matching this heavy expansion battery to an existing system.

## Frequently asked questions

### How many BP5000 batteries can the system use?
The listing says up to five BP5000 modules, but its stated system capacity is contradictory. Confirm the supported configuration and total capacity for the exact Solarbank model.
### Can the battery be moved around easily?
It is listed at 42 kg and marked as not portable. The manufacturer text recommends two people carry it.
### Can it be installed while the Solarbank is running?
No. The listing says the system must be completely powered off and PV and AC inputs disconnected before installation or removal.
### What is included in the package?
The feature text lists one BP5000 battery, two fixed brackets, six M5 × 10 mm screws, four M6 × 50 mm expansion screws and two wall mount fittings. The separate included-components field is only a slash, so check the selected listing's package contents.
