How buying this works
Roam Wired does not stock this item. The button above hands you over to the seller's own shop, where you place the order, pay and arrange delivery directly with them. Nothing is added to a Roam Wired basket, and we never see your payment details.
We list it because it is the part our calculator would specify for a build like yours, not because we make the most on it. How we make money
Delivery and returns
Delivery cost, delivery time and the returns window are set by the seller, not by us, and Roam Wired's own £10 / free-over-£250 UK delivery does not apply here. Check their delivery and returns terms on their product page before you order.
Your consumer rights, including the 14-day right to cancel a distance sale, are against the seller who took your order.
Warranty and support
The manufacturer's warranty is handled by the seller you buy from. If something fails, raise it with them and quote their order number — we cannot open a claim on your behalf.

Overview
12V 3000W HF Inverter Charger Pure Sine Wave High-Frequency
3,000W inverter, charger and UPS, still only 113mm thick and 7.7kg. The larger of the Core high-frequency units — induction hob, microwave and kettle territory, in a case that fits where a low-frequency unit never would. Also sold as a 2,000W.
- 3,000W continuous at 30°C
- 6,000W surge for 100ms, 4,500W for 3s, 3,600W for 35s
- 230V AC ±3%, 50Hz ±0.1Hz
- Under 20ms UPS transfer, 91% peak efficiency
- Under 10W no-load, THD under 4%
- 7.7kg, 432.4 × 305 × 113.3mm
Derating is the number to plan around
Renogy rate this at 3,000W at 30°C and state that output degrades above that. In a van in August, in a cupboard, ambient is comfortably past 30°C — which means the 3,000W figure is a laboratory number, not a summer afternoon number. Give it real airflow, or accept that it will quietly back off exactly when you are using it hardest.
Check the battery can supply it
3,000W at 12V is around 270A of DC draw. Several packs cap continuous discharge at 100A or 150A, so pair this with a bank rated to 200A or more, and size the DC cable and fuse for the full current over a short run.
Before you order
Operating range is −20°C to 50°C, wider than the PUH inverters, so it tolerates a colder locker. Bluetooth is a separate module. 230V work should be certified by a qualified electrician.
