Key features

25A DC-DC output charges auxiliary battery with a multi-stage algorithm (bulk, absorption, float) regardless of alternator voltage
Inbuilt 20A MPPT solar regulator accepts direct solar panel input up to 50V open-circuit voltage
Compatible with LiFePO4, AGM, gel, calcium, and flooded lead-acid battery chemistries — selectable via mode switch
Wide input voltage range of 9–32V DC accommodates smart alternators, EFB and AGM start batteries in modern vehicles
Dual-input intelligence prioritises and combines DC-DC and solar inputs simultaneously for maximum charge rate
Automatic temperature compensation adjusts charge voltage to protect batteries in extreme Australian conditions
Compact, fan-cooled aluminium enclosure with IP22 protection rating suits under-bonnet and enclosed-compartment mounting
LED indicator array displays charging stage, input source activity, and fault status at a glance
Reverse polarity protection, over-temperature shutdown, and short-circuit protection on all ports
Supplied with mounting hardware and connection leads — ready to install straight out of the box

Overview

The KT Solar KSDC25A is a 25A DC-DC battery charger with an inbuilt 20A MPPT solar regulator, purpose-built for 12V dual-battery systems in caravans, camper trailers, 4WDs, and motorhomes. Unlike basic voltage-sensing isolators, the KSDC25A employs a true multi-stage charging algorithm — bulk, absorption, and float — to deliver a full, correctly profiled charge to your auxiliary battery regardless of your vehicle's alternator type. Its wide 9–32V DC input range fully supports modern smart alternators, EFB, and AGM start batteries, while the inbuilt MPPT solar input accepts panels up to 50V open-circuit voltage and harvests up to 95% conversion efficiency for maximum solar yield.

Whether you're running a lithium LiFePO4 drop-in, an AGM deep-cycle, or a traditional flooded lead-acid battery, the KSDC25A's selectable battery chemistry profiles ensure every setup gets the correct charge voltages and temperatures. Dual-input intelligence lets the unit draw from your alternator and solar panels simultaneously, giving you the fastest possible recharge during long touring days on Australian outback tracks, coastal caravan parks, or remote free-camping spots. Automatic temperature compensation protects your batteries through Australia's extreme seasonal conditions, while the compact, fan-cooled IP22 aluminium enclosure fits neatly under the bonnet, in a caravan tunnel boot, or inside a camper trailer's battery compartment.
