What to know before buying

Listing details to confirm

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.

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.
