Inverter Selection Guide: Choosing the Right System for Your Caravan

An inverter is what turns your battery's stored DC power into the AC power your appliances actually run on. Choosing the wrong one — or skipping it entirely — is the difference between a 48V system that runs your induction cooktop and one that just charges phones.

Why 48V Systems Need an Inverter

Your DCX 48V battery stores DC power. Standard household appliances — induction cooktops, microwaves, coffee machines, air conditioning — run on AC power. The inverter is the component that makes that conversion, and it's not optional if you want to run mains-style appliances off your battery.

The DCX 5000W Inverter Range

OzX offers two 5000W pure sine wave inverters, differing only in solar input voltage range — both share the same core specification:

• Output: 5000W continuous
• Integrated 13.2V 100A supply — runs your caravan's 12V accessories directly from the same unit
• Integrated DC-DC charger input (unregulated) — flexible charging setup options
• Included: base plate and plug-and-play connectors for straightforward installation
• Warranty: 3 years
• Dimensions: 650 x 400 x 350mm, 26.5kg

60–120V Solar Input Model

Suited to standard solar array configurations — the entry point for most caravan and RV solar setups.

120–450V Solar Input Model

Built for larger, higher-voltage solar arrays — the right choice if you're running (or planning to run) a bigger panel setup and want headroom to expand.

Sizing Your Inverter to Your Load

A 5000W continuous rating covers the vast majority of caravan appliance combinations — induction cooktops, microwaves, coffee machines, and air conditioning can all draw from the same 5000W inverter, though not all at their peak draw simultaneously without careful load management. Pair this with your battery sizing to make sure the battery behind it can actually sustain that draw for as long as you need it to.

Why Integrated 12V Supply Matters

Both DCX inverters include a built-in 13.2V 100A supply, which means you're not running a separate DC-DC charger just to keep your caravan's 12V accessories powered — lighting, water pumps, and USB charging all run from the same unit as your AC appliances.

Frequently Asked Questions

Do I need an inverter if I have a 48V battery?
Yes — the battery stores DC power, but standard AC appliances (induction cooktops, microwaves, air conditioning) need an inverter to convert that DC power into usable AC power.

What's the difference between the two DCX inverter models?
Both are 5000W pure sine wave inverters with identical core specifications — the only difference is solar input voltage range (60–120V vs 120–450V), which determines what size solar array you can pair with each.

Can one inverter run air conditioning and induction cooking at the same time?
The 5000W continuous rating can handle a range of appliance combinations, but running multiple high-draw appliances simultaneously at their peak draw needs careful load management — pairing with a larger battery like the DCX 48V 14.3kWh or 16.1kWh gives you more headroom.

Do I still need a separate DC-DC charger with a DCX inverter?
Both DCX inverters include an integrated DC-DC charger input (unregulated) and a 13.2V 100A supply built in, reducing the need for entirely separate charging hardware — though your specific setup may still benefit from additional charging options depending on your solar and driving-charge configuration.

What's the inverter warranty?
3 years on both DCX 5000W inverter models.
