Sunsynk · 5.12 kWh · HV series battery unit
Sunsynk 5.12kWh HV series battery unit
This is the 5.12kWh single battery unit for Sunsynk's HV series, sold on its own rather than as part of a packaged system. It is the part you order when an existing HV stack needs more capacity than it was first commissioned with.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Storage needs rarely stay where the original survey put them. A customer adds an EV or a heat pump, and the stack that was right last year now runs flat by early evening. Buying the single 5.12kWh unit lets you extend in sensible steps instead of quoting a whole second system, and it keeps commissioning familiar: same brand, same series, one supplier. The rate on this page is the ex-VAT rate on the invoice, whatever the quantity, which makes small extension jobs worth pricing properly.

What it pairs with
Keep it inside the HV family. The BMS for the Sunsynk HV series (SUN-HV-BMS) manages any stack it joins, and complete builds such as the Sunsynk 20.48kWh HV battery system (SUN-HV-20.48) are the towers this unit typically extends. Unit counts per stack depend on system revision, so check Sunsynk's current stacking list before committing an extra module to a quote.
A single battery unit for the HV series, not a standalone system: it needs the series BMS and a compatible Sunsynk hybrid inverter around it. Capacity is 5.12kWh per unit. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
