HiTech 3-in-1 Direct Flow DC Charger

HiTech 3-in-1 Direct Flow DC Charger – Smart Combined Battery Charger

The HiTech 3-in-1 Direct Flow DC Charger combines a DC-DC (alternator) charger, an MPPT solar controller, and a 240V AC mains charger in a single compact unit — eliminating the need for three separate devices. It's designed for caravans and motorhomes that want one clean, integrated charging solution for their battery bank from every available power source: solar, alternator and shore power.

Direct flow technology manages charging from each source intelligently, prioritising and balancing input across all three so your battery gets the fastest safe charge available at any given time — whether you're driving, parked in the sun, or plugged into a powered site.

Key Features

• 3-in-1 Design – DC-DC charger, MPPT solar controller and AC mains charger combined in one unit
• High Combined Output – up to 100A combined charging current across all sources, with a 60A fast-charge mode and a 30A slow-charge mode
• Smart Management – automatically prioritises and balances charging from solar, alternator and shore power
• 240V Shore Power Input – plugs into a standard NZ powered site, accepting up to 40A input
• MPPT Solar Charging – accepts solar input up to 26V at up to 60A for efficient panel charging
• Multiple Battery Profiles – selectable charge settings to suit different battery types
• Comprehensive Protection – overvoltage, undervoltage, current limiting and thermal protection

Brand Quality – a genuinely multi-source charging solution from HiTech Power Solutions, backed by the manufacturer's 1-year warranty and built to keep your batteries charged and healthy from wherever your power comes from.

What size charger do I need for my battery bank?
A general rule is a 10–20% charge rate. For a 100Ah battery bank, a 10–20A charger is appropriate; for 200Ah, a 20–40A charger; for large lithium banks of 300Ah and above, a 40–60A charger significantly reduces charge time. Faster charging isn't harmful provided you don't exceed the battery manufacturer's maximum charge rate — this unit's 60A fast-charge and up to 100A combined output suit larger banks well.

Can it charge from solar, the alternator and shore power all at once?
Yes. The unit's smart management automatically prioritises and balances input from all three sources, so you get the fastest safe combined charge available whenever more than one power source is connected.

Will it suit my battery chemistry?
The charger offers multiple selectable battery profiles to suit different chemistries. If you're unsure which setting matches your battery bank, contact us with the battery make and chemistry and we'll advise the correct profile.
