Polar external battery housing
When the batteries cannot go indoors, this is where they live: the Polar external housing is a weatherable enclosure that holds four Polar battery modules behind a security cover. It moves the storage stack outside without leaving the modules exposed.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Four batteries fit inside, and the security cover keeps them shielded once the stack is built and closed up. That makes it the answer for installs where loft, garage or utility space has run out, or where the customer would rather keep the storage off the living wall entirely. It is a housing, so it supplies the enclosure and the cover, not the batteries or cabling. Ordering follows the trade pattern: the ex-VAT price on this page is your account rate, from UK stock, on any quantity.

What it pairs with
The housing is built around the Polar ESS line, so it pairs with Polar ESS batteries such as the Polar ESS 5.12 kWh battery, alongside a Polar ESS inverter like the Polar ESS 3.6 kW or 6 kW unit. Battery-to-battery cabling completes the internal run. Module fit and count depend on the Polar battery revision, so check the four-module layout against Polar's current Polar compatibility list before ordering.
Houses up to four modules; batteries, inverter and cabling are separate lines. Site the enclosure to the manufacturer's outdoor guidance. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
