Unitura 3000W Inverter Charger SRNE SR-RIC12-3KW 12V Pure Sine

There is one moment when an inverter has to prove itself. Not with a laptop. Not with a string of lights. But when the coffee machine kicks in, the fridge compressor starts and you need the hairdryer at the same time. The SR-RIC12-3KW is built for exactly that moment.

6000 watt surge. Double the rated power — and that is the exception.
Most 3000 watt inverters deliver roughly one and a half times their rating for a short burst. This one doubles it: 6000 watts of starting power. Motors, compressors, pumps and power tools draw a multiple of their rated power at start-up — and that is exactly where cheap units give up. Here you keep headroom instead of a shutdown.

Pure sine wave. No compromise for sensitive equipment.
Total harmonic distortion below 3 percent and a power factor of 1: an output cleaner than the supply in many holiday homes. Induction hob, CPAP machine, coffee machine, battery chargers, laptop power supplies — everything runs the way it should. No humming, no error messages, no premature wear.

Inverter and charger in one housing.
As soon as shore power is available, the unit switches over automatically: your loads keep running from the grid while the built-in charger refills the battery with up to 200 amps. If the power fails, the inverter takes over without interruption. One device, one cable set, no second charger in the cabinet.

Safety that normally lives in the fuse box.
An RCD earth leakage breaker sits on the 230 volt output — factory-fitted, inside the unit. You will practically never find this on a mobile inverter. Add protection against battery over-voltage and deep discharge, overload, short circuit and over-temperature, plus surge protection designed specifically for lithium systems. Tested to IEC 62109-1/2, EN 61000-6-1/3 and IEC 60335 — standards from fixed installation engineering, not from the accessories shelf.

From the camper into the engineering.
The SR-RIC12-3KW is not an AutoSolar in-house product. But what we know from thousands of camper conversions went into SRNE's development work: which inrush currents really occur in practice, which protective functions are missing in mobile use and what matters during installation.

Camper and motorhome. Coffee machine, induction hob, hairdryer, tools — with 3000 watts of continuous power the debate about what you are allowed to bring is over. Bluetooth on board: power, state of charge and fault messages are read straight from your phone.

Boat and onboard system. Seamless transfer between shore power and battery, with no restart of navigation or refrigeration. On the water, integrated earth leakage protection is not an extra — it is basic equipment.

Backup power, workshop and site. As a fallback during an outage, the SR-RIC12-3KW keeps heating controls, fridge, router and lighting alive without anyone moving a plug. On site it delivers 230 volts where there is none yet.

Straight talk. 3000 watts from 12 volts means around 300 amps on the DC side. That calls for short, properly sized cables, the right fuse and a battery bank that can actually deliver that current. Give us a call — we will size your system with you before you order.

Selected, tested and shaped by AutoSolar. So that 230 volts is exactly where you are.
