Projecta Automatic 9-32V 45A 3 Stage DC/Solar Battery Charger, 1 Year Warranty. Following the enormous success of the IDC25 DC/Solar Battery Charger, Projecta has now released a 45 Amp version that combines many of the market-leading features of the original, with a much larger output designed to deliver faster charging and handle more demanding applications. Allowing you to charge your 12V second/auxiliary deep cycle battery on the go, the IDC45 is shock, vibration and dust proof. The unit is also water resistant, making it suitable for both in-vehicle and under-bonnet installation.
Able to charge simultaneously from both solar and alternator (9–32V) inputs, IDC45 can also function as an MPPT solar controller and features dual charging modes for compatibility with both smart and conventional alternators. Loaded with a host of safeguard features, the easy to install unit includes over/under voltage, anti-sparking, reverse connection and over temperature protection systems to ensure peace of mind.
The IDC45 provides the ultimate solution for the most demanding DC/Solar battery charging applications.

  • Dual Input Operation: Simultanous dual battery charging from both solar and alternator inputs, no manual switching required
  • Dust, Splash & Shock Proof: Sealed to IP67, IDC45 will resist dust, water and shock damage, making it ideal for under bonnet installation
  • 80 Degrees Celsius: IDC45 can safely operate (at a reduced charge rate) in extreme temperatures up to 80° C, as found in engine bays in hotter climates
  • Temperature Compensation: IDC45 will continually adjust its charge voltage to suit the battery temperature, protecting it from overcharge and overheating
  • Push Button Chemistry: Adjust battery chemistry at the touch of a button for optimum charging
Dual input operation:

Simultaneous dual battery charging from both solar and alternator inputs (9–32V) with no manual switching required. The unit prioritises solar charging as its default and automatically adjusts to the alternator if sunlight is insufficient, reducing the power usage placed on the vehicle’s electrical system.

Dual charging modes:

Engineered to work with both smart and conventional alternators. The introduction of smart alternators has resulted in many conventional dual battery systems being ineffective. The advanced switch-mode technology of the IDC range enables greater efficiency, exceeding 94% at typical full load conditions, converting your vehicles alternator power to a more complete charge.

25A solar MPPT:

Using sophisticated Maximum Power Point Tracking (MPPT) solar regulator technology, the IDC range of chargers operate as advanced solar controllers, maximising the power generated from the panels to provide a comprehensive and total charge to your auxiliary battery.

Multi-chemistry charging:

The IDC range of chargers suit todays different battery technologies, including everyday automotive batteries and the newer Lithium battery technology. For automotive batteries, multi-chemistry technology enables the user to tailor the charging profile to suit the battery type: Gel, AGM, Wet and Calcium batteries.

Multi-stage charging:

Utilising sophisticated electronics, the IDC range of DC/SOLAR chargers provide an advanced multi-stage charging process to produce a safe and comprehensive charge, a must for deep cycle and lithium batteries.

Q & A

  • Can this charge a 24 lifepo4 battery from an alternator?

    Hi There,

    The Projecta IDC45 is not suitable for charging lithium batteries.

    The output voltage is also only 12V and is not suitable for charging 24V batteries.

    A suitable alternative would be the following:
