Description

Half the cost of a first fix is the bits that are not in the box: an isolator from one wholesaler, cable from another, and a second visit when either turns up late. This pack removes that risk. Isolator and cables are included, the housing is IP65 rated, and the capacity is a straightforward 5.32kWh per unit. For a trade buyer that means fewer part numbers on the purchase order and fewer chances for a job to stall on a missing accessory.

What it pairs with

Pair it with a hybrid inverter from the same stable, such as the Sunsynk 3.6kW ECCO (SUN-3.6-ECCO) or the Sun 5K ECCO (SUN-5.0-ECCO), and add the Sunsynk long cable set (SYNKIP65-LONGCABL) where the battery sits further from the inverter. Battery pairing can vary by model and firmware revision, so run the combination past Sunsynk's current compatibility list first.

Single-phase family, and a battery on its own does nothing: plan for a compatible Sunsynk hybrid inverter on the same job. Capacity is fixed at 5.32kWh. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.

FAQ

Sunsynk SUNSYNK-L5.3 buying questions

It is on this page, ex VAT, visible without an account. VAT at 20% goes on at invoice stage. There are no volume brackets: the unit rate for a single battery matches the rate on a bulk order, and there is no minimum order value, so a one-off job costs no more per unit than a fleet buy.
By pallet. Lithium batteries are UN3480 Class 9 dangerous goods, so a DG-capable freight carrier handles it rather than a parcel network. Expect 3–5 working days (estimate). The dispatch clock starts at cleared payment. The drop is kerbside, so have someone on site to take it in.
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.
