Sunsynk Busbar 300 energy management busbar

The Busbar 300 is Sunsynk's connection busbar for energy management system builds, giving the system's cabling a single common landing point. It suits installers specifying multi-unit Sunsynk installations where running every conductor to one terminal would get untidy fast.

Description

A busbar is the sort of part that never headlines a quote but halts a job when it is missing. Keeping the Busbar 300 on the same order as the Sunsynk inverters and batteries it serves means one delivery, one invoice and no mid-install parts hunt. It is a plain accessory from the same catalogue as the rest of the Sunsynk energy management range, so the kit list stays single-brand and the price on this page is the ex-VAT price on the invoice.

What it pairs with

Specify it alongside the Sunsynk hybrid inverters it will serve, such as the Sun 8K ECCO or the 12kW single-phase Classic, with the Sunsynk long cable set for battery to inverter covering the runs to it. Layouts vary with model and firmware revisions, so confirm the wiring arrangement against Sunsynk's current pairing and stacking list before finalising the design.

This is a connection accessory with no generation or storage capacity of its own; the inverters and batteries around it do the work. It is listed for single-phase Sunsynk systems. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.

FAQ

Sunsynk SUNSYNK-BB-300 buying questions

The ex-VAT trade price sits on this page and VAT at 20% is added on the invoice. The price is the same whether you buy a single busbar for one job or a handful for the van, because there are no minimum order quantities and no volume tiers to negotiate.
It carries no lithium cells, so it travels by parcel courier rather than dangerous goods pallet freight, and nobody needs to wait in for a kerbside drop. Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment. Add it to a larger Sunsynk order so the small parts arrive with the hardware they serve.
Out of stock at the last catalogue update, and the count on this page comes from the live stock feed rather than a manual list. In stock means in stock; if the number reads zero, the trade desk can tell you the restock position for this part number.
