Running household 240V appliances in the middle of the bush is no longer a luxury reserved for massive motorhomes. Whether you want to cook on an induction cooktop, brew fresh espresso on the trail, run a portable air conditioner, or power heavy tools on the job site, a reliable high-output inverter is essential.
Building on the popularity of the 2,000W model, DC Direct is excited to announce that the Invicta 3,000W Pure Sine Wave Inverter (12V to 230V), featuring an integrated Automatic Transfer Switch (ATS) and built-in Safety RCD Protection, is now available for pre-order.

Why the Integrated ATS & RCD Safety Switch Matters
Standard off-grid inverters often require external safety switches, complex sub-boards, or manual transfer relays to be safe and compliant. The Invicta 3,000W model integrates all these critical components directly into the chassis:
-
Integrated Safety RCD (Residual Current Device): Provides immediate electrical hazard protection against earth leakage, safeguarding you and your family when plugging in 240V appliances off-road.
-
Automatic Transfer Switch (ATS): When your rig is plugged into mains shore power (at home or a caravan park), the ATS automatically passes grid power directly to your outlets. The moment you unplug, it instantly switches back to drawing battery power from your inverter with zero interruption.

Frequently Asked Questions
What DC battery setup do I need to run a 3000W inverter?
To pull a full 3,000W load at 12V DC, your inverter can draw upwards of 250A to 300A continuously. We strongly recommend pairing this inverter with a high-discharge LiFePO4 battery bank (such as a 200Ah–400Ah lithium bank) equipped with a BMS rated for high continuous discharge currents.
At DC Direct, three Invicta lithium batteries suit this kind of load particularly well:
-
The Invicta SuperSlim Lithium 12V200Ah (SNLSS12V200BT) carries a 250A continuous discharge rating, enough to cover the full continuous output of this inverter from a single battery.
-
The Invicta Xero Lithium 12V200Ah (SNLX12V200BT) and 12V300Ah (SNLX12V300BT) are rated at 150A continuous each, so these generally suit lighter continuous loads or are paired in parallel when running closer to the inverter’s maximum draw.
Any battery can be checked against an inverter using a simple formula from its specification sheet: Nominal Voltage x Max Continuous Discharge = Watts. For example, 12.8V x 250A = 3,200 Watts, which comfortably covers a continuous 3,000W load with some margin to spare.
What is the benefit of a Pure Sine Wave inverter over a Modified Sine Wave inverter?
Pure Sine Wave inverters output a clean, smooth electrical wave identical to the 230V AC power supplied by the grid. Modified sine wave inverters produce harsh, blocky square waves that can overheat motors, create humming noises in audio gear, or permanently damage sensitive appliances like coffee machines, laptops, and battery chargers.
How does the Automatic Transfer Switch (ATS) save battery power?
When you plug your caravan or canopy into 240V mains grid power (e.g., at home or a powered campsite), the built-in ATS detects the incoming grid power and automatically bypasses the battery inverter. This powers your 240V outlets directly from the grid, preserving your auxiliary lithium batteries for when you go off-grid.
Is an RCD safety switch required on an off-grid inverter?
Yes, fitting an RCD (Residual Current Device) switch is a vital electrical safety requirement for 240V installations. It instantly trips power if an electrical fault or short occurs, protecting users from hazardous electric shocks. Having the RCD integrated directly into the Invicta inverter saves installation cost and time.
Can I mount the inverter in any orientation?
The Invicta 3000W inverter should be mounted in a well-ventilated, dry compartment with sufficient clearance around its cooling fans. Avoid mounting it in unventilated boxes or near flammable gases. Speak to the DC Direct Team for professional wiring and installation advice.
