Redarc 3000W 12V Inverter with ATS and RCD

3000W continuous output with a 6000W surge for two seconds

Automatic Transfer Switch moves between battery and mains without you touching anything

In-built Residual Current Device protects the 240V output against electric shock

Assists AS/NZS 3001 compliance in caravan and RV installations

IEC C20 input with IEC C19 and 15A GPO outputs, so the 240V side plugs in rather than being hardwired

Pure sine wave output suits sensitive electronics

Load-controlled cooling fan, so it runs quietly at lower draw and only ramps up under heavy load

Vibration-resistant aluminium shell built for corrugations and heat

Ships Australia-wide. Local pickup available from our Perth store.

Q: What can a 3000W inverter actually run?
A: High-draw equipment such as air conditioners, microwaves, toasters and coffee machines, or several smaller appliances at once. The 6000W surge rating covers the start-up spike from motors and compressors.

Q: How is the RS3 different from the older RS 3000W?
A: The RS3 adds an Automatic Transfer Switch and an in-built RCD, and uses plug-in IEC connections instead of a hardwire plate. It is a physically different unit as well, at 10.3kg against 8.2kg.

Q: Can I leave it connected when I plug in at a caravan park?
A: Yes. The Automatic Transfer Switch moves between mains and battery on its own, so you are not swapping leads or draining the battery when shore power is available.

Q: What does the in-built RCD do?
A: It acts as a circuit breaker on the 240V output, cutting power if it detects a fault, and it assists with AS/NZS 3001 compliance in caravan and RV builds.

Q: What battery do I need to run it?
A: At full output a 3000W inverter draws roughly 250A from a 12V battery before conversion losses, so plan on a bank rated to at least 300A continuous discharge. Our Custom Lithium Next Generation 310Ah is rated to 330A continuous, which covers the RS3 at full load. A smaller bank will still run the inverter, but not at full output for long.

Q: Do I need an electrician to install it?
A: No. The RS3 connects on the 240V side with plug-in IEC leads rather than fixed wiring, so a standard installation does not need one. The 12V side still needs correctly sized cable and fusing. Our Perth workshop fits and tests these if you would rather not do it yourself.
