The perfect addition to any off-grid system, whether for a caravan or a cabin, the Renogy 3000W Pure Sine Wave Power Inverter acts as a DC to AC converter, allowing you to power your household appliances. Unlike modified sine wave inverters, this 3000W inverter is a pure sine wave, capable of producing cleaner, smoother, and more reliable electricity to operate tools, fans, lights, and other electronics without interference. Many off-grid systems require a 12V solar inverter to power everyday electronics, and this one includes multiple protections to help things run smoothly and safely. The AC priority function enables the inverter to automatically switch from the battery (DC) to the mains (AC) and vice versa whenever the utility company takes or loses power!

1. Is this inverter suitable for overnight caravan use??

Yes. The low-noise intelligent cooling system is designed for quieter overnight use in caravans, RVs and cabins, helping keep sleeping spaces more comfortable while running essentials like fridges, fans and CPAP devices.

2. Will it fit under my caravan seat or side cabinet?

Yes. With its slim 92mm profile and compact 482 × 220mm footprint, this inverter is ideal for under-seat storage, side lockers and tighter off-grid battery compartments.

3. Does UPS backup keep Wi-Fi and CPAP running?

1. The built-in UPS function switches from AC to battery within 50ms, helping keep Wi-Fi routers, CPAP machines, fridges and work laptops powered during outages.

4. Can I use this inverter with a 24V battery system?

No. This is a 12V pure sine wave inverter, so it must only be used with a 12V battery bank. For 24V systems, please choose a 24V-compatible inverter model.

5. Will this inverter work with lithium batteries?

Yes. It is compatible with 12V lithium batteries, including LiFePO4, as long as the battery system matches the inverter’s 12V DC input requirement.

Please note: DC cables aren't included. You'll need to supply your own.

6. Does this inverter include a built-in RCD?

No. This inverter does not include a built-in Residual Current Device (RCD / safety switch). For installations in Australia, an external RCD rated ≤30mA must be installed on both the AC input and AC output side by a licensed electrician to comply with: AS/NZS 3000 (Wiring Rules) AS/NZS 3001.2 (Electrical Installations – Transportable Structures) This is the standard installation method for Australian caravans, cabins and home backup systems, and is commonly used by licensed RV and residential electricians.

7. What size inverter should I buy?

Choose an inverter based on: 1) Appliance wattage Add the total wattage of all devices you plan to run at the same time. Example: Fridge: 500W Air conditioner: 800W Total: 1300W A 3000W inverter gives extra headroom for startup surges and future upgrades. 2) Battery voltage This model requires a 12V battery system. 3) Installation space Its slim 92mm thickness makes it easier to fit under caravan seats, in side lockers or compact battery bays.

8. What cable size should I use, and is it included?

For best performance, use the shortest and thickest DC cables possible to reduce voltage drop. Recommended: up to 3m: 25mm²–35mm² longer runs: 35mm²+ Please note: DC cables are not included and must be sourced separately.
