Sunsynk · 5.32 kWh · IP65 battery pack (black)
Sunsynk W5.3 5.32kWh IP65 battery, black
The W5.3 in black is a 5.32kWh IP65 Sunsynk battery supplied with its cable sets. It earns its keep on retrofits, adding storage to a site that already runs a Sunsynk hybrid inverter without disturbing what is on the wall.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Retrofit work punishes messy ordering. The inverter and wiring are already on site, so what you want is the battery, the leads to connect it and nothing else. This pack keeps it that tight: battery plus cable sets under one part number. The black case sits comfortably next to dark hardware, the housing carries an IP65 rating, and 5.32kWh is a sensible first storage step for a typical household. If the customer later wants more, the same family scales without changing supplier.

What it pairs with
Its natural partners are Sunsynk's own hybrid inverters, the ECCO models (SUN-3.6-ECCO, SUN-5.0-ECCO) among them, with the battery to battery cable pack medium (SUN-CABLE-MEDIUM) on hand where more than one unit goes in. Which inverters accept which batteries can shift with model and firmware revisions, so confirm the pairing on Sunsynk's current compatibility list before quoting.
One battery, one job: it stores energy and needs a compatible Sunsynk hybrid inverter to charge or discharge. Each unit holds 5.32kWh. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
