iTECHDCDC40 | DCDC and MPPT Battery Charger | 12V/24V 40A

A$ 399AUD · price may vary

Model: DCDC40
Specifications: 0

Overview

The iTECHDCDC40 keeps your battery charged no matter the battery type or size.

The iTECHDCDC40 charger incorporates an MPPT solar controller allowing charge from solar panels or blankets. When the vehicle runs, the DCDC charger will charge via the alternator; when the vehicle stops, the iTECHDCDC40 will continue charging via your solar panels/blankets (if added).

Exclusive to iTechworld DCDC chargers is a function known as Solar Power Priority (SPP) which represents the preference for solar input. This allows you to set your iTECHDCDC40 to use solar input over the vehicle alternator's input at the push of a button. Solar Power Priority places less load on the alternator, is better for the environment and helps to reduce fuel consumption.

Designed and developed in Australia for Australia, the iTECHDCDC40 is IP67 Waterproof, Dustproof and vibration-proof. Built with a heavy-duty metal case uniquely designed to help with heat dispersion, the iTECHDCDC40 is suited and warranted for under-bonnet installation. Mounting brackets are included in the case design, allowing for easy installation in your setup.

Many vehicles now have smart alternators that do not produce a high enough voltage to charge auxiliary batteries; the iTECHDCDC40 works by enhancing the voltage to the auxiliary battery regardless of the alternator type; the enhancement of voltage is also valuable for overcoming voltage drop from long cable runs to caravans and camper trailers.

If your car has a smart alternator, the iTECHDCDC40 has you covered with its easy-to-connect 3-pin Anderson, which allows operation with any alternator.

A unique feature of the new iTECHDCDC40 is the ability to accept a wide voltage input range from either solar or vehicle input, with the maximum input voltage now being 32v. As the iTECHDCDC40 accepts higher input voltages, it opens the door to 24v inputs as well as some larger voltage solar panels commonly found in residential installations.

The new iTECHDCDC40 is compatible with all battery types but comes into its own when paired with iTechworld lithium batteries. All iTechworld lithium batteries have low voltage protection and will enter "safe mode" to protect themselves when their voltage dips below 10v. There are various methods to bring an iTechworld lithium battery out of safe mode, but the new iTECHDCDC40 will get an iTechworld lithium battery out of safe mode automatically; if the lithium battery enters safe mode, turn off any load on the battery and the iTECHDCDC40 will take care of the rest, it's that simple.

How to read this datasheet

Detailed specifications for iTECHDCDC40 | DCDC and MPPT Battery Charger | 12V/24V 40A have not been published yet. iTechworld lists this charge controller in the Charge Controllers, and we add fields as the manufacturer releases them — in the meantime, ask your distributor for the datasheet before ordering.

For a charge controller, the figures that matter most are maximum PV open-circuit voltage, the hard limit that must survive cold-morning Voc rise, supported battery voltages (12/24/36/48 V) and chemistries, conversion efficiency, typically 96–99% for a good MPPT unit and whether it offers a load output, temperature compensation and remote monitoring. In any system with a battery and a separate array, the controller is what protects the most expensive component and determines how much of the array's output actually reaches storage.

Before you buy a charge controller

The checks below apply to any charge controller. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Size the current rating from array watts divided by battery voltage, then add at least 25% margin for cold, bright conditions where panels exceed their rated output.
Check the maximum PV input voltage against the array's Voc at your coldest expected temperature, not at 25 °C — Voc rises as temperature falls, and exceeding the limit destroys the controller instantly.
Confirm the controller supports your battery chemistry with the right charge profile. Lithium, AGM, gel and flooded batteries need different absorption and float voltages.
Prefer a unit with temperature compensation or a battery temperature sensor if the bank lives somewhere that gets hot or cold.

What people get wrong

Sizing on rated array watts alone and ignoring the voltage ceiling, which is the most common way controllers are killed.
Using a PWM controller with a high-voltage grid-tie panel — the voltage mismatch wastes a large share of the panel's output.
Running the load output beyond its rating instead of wiring heavy loads directly to the battery through a fuse.

Price and availability

iTECHDCDC40 | DCDC and MPPT Battery Charger | 12V/24V 40A is listed at A$ 399 (AUD). Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in your country: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports iTechworld locally before ordering.

iTECHDCDC40 | DCDC and MPPT Battery Charger | 12V/24V 40A — frequently asked questions

How much does iTECHDCDC40 | DCDC and MPPT Battery Charger | 12V/24V 40A cost?

iTECHDCDC40 | DCDC and MPPT Battery Charger | 12V/24V 40A is listed at A$ 399 (AUD). The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

Who makes iTECHDCDC40 | DCDC and MPPT Battery Charger | 12V/24V 40A?

iTECHDCDC40 | DCDC and MPPT Battery Charger | 12V/24V 40A is a iTechworld product, listed under charge controllers with model reference DCDC40. The iTechworld brand page lists the rest of its range so you can compare across the catalogue.

Is iTECHDCDC40 | DCDC and MPPT Battery Charger | 12V/24V 40A right for my system?

That depends on what it has to connect to. For a charge controller, check conversion efficiency, typically 96–99% for a good MPPT unit, whether it offers a load output, temperature compensation and remote monitoring and type: MPPT or PWM against the rest of your equipment before price enters the decision. Confirm the controller supports your battery chemistry with the right charge profile. Lithium, AGM, gel and flooded batteries need different absorption and float voltages.

Where can I buy iTECHDCDC40 | DCDC and MPPT Battery Charger | 12V/24V 40A?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer — buying in-channel is what keeps the manufacturer's warranty valid.
