Sunsynk L5.3 5.32kWh battery with isolator
The Sunsynk L5.3 is a 5.32kWh IP65 battery that ships complete with its isolator and cables. Spec it when you want the whole battery side of a new install to arrive as one line on one order.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
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.
