Sunsynk 20.48kWh HV battery system
Sunsynk's 20.48kWh HV battery system is a complete high-voltage storage build specified as a single line item. It is aimed at new installs where the load calculation lands well beyond what a wall-hung battery can sensibly cover.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Specifying storage at this scale from loose parts invites errors, so a packaged HV system earns its place on the order. You quote one product, order one product and commission one product, and the capacity headroom means the design survives the customer adding loads later. Sunsynk backs it with a proper ecosystem in this catalogue: a dedicated cabinet, a series BMS and single battery units for future extension, which keeps the upgrade path inside one brand and one supplier relationship.

What it pairs with
The battery cabinet with door made for this system (SUN-HV-20.48-BATTRACK-DOOR) is the obvious first addition, with the HV series BMS (SUN-HV-BMS) managing the stack and the 5.12kWh single battery unit (SUN-HV-5.12-BATT) available when capacity needs to grow. Inverter choice and stack limits vary with model and firmware revision, so work from Sunsynk's current pairing and stacking list.
A battery system, not a generator: what it delivers depends entirely on the inverter it is paired with, and the family is listed single-phase in this catalogue. Total capacity is 20.48kWh. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
