The SRNE SR-IBC12-3kW Pure Sine Wave Inverter is a powerful 3000W inverter designed to provide reliable 230V mains electricity from a 12V battery system. Ideal for campervans, motorhomes, caravans and off-grid installations, it allows you to operate household electrical appliances without relying on an external mains supply.
Unlike a conventional inverter, the SRNE IBC12-3kW incorporates an automatic mains bypass function, allowing connected appliances to operate from an external 230V supply when available. When mains power is disconnected, the inverter can automatically switch back to battery power, providing a practical solution for motorhome and campervan electrical systems.
With Bluetooth monitoring, selectable operating modes and a 6000W peak surge capacity, this inverter combines high-output performance with intelligent power management.
Key Features
• 3000W Continuous Output – Suitable for powering a wide range of 230V electrical appliances.
• 6000W Peak Surge Capacity – Handles short-duration starting loads from compatible equipment.
• Pure Sine Wave Output – Delivers clean, stable electricity suitable for sensitive electronic devices.
• Automatic Mains Bypass – Automatically transfers between external mains electricity and inverter operation.
• Fast UPS Switching – Transfer time of less than 10 milliseconds.
• Built-in Bluetooth – Monitor operating information and fault conditions using a compatible mobile application.
• Energy-Saving ECO Mode – Reduces battery consumption when electrical demand is low.
• Remote Switching Capability – Supports external on/off control for convenient installation.
• Integrated Safety Protection – Includes protection against overload, short circuits, overheating and battery voltage faults.

Intelligent Power Management
The SRNE IBC12-3kW offers selectable mains priority and inverter priority settings, allowing the electrical system to operate according to your requirements.
In mains priority mode, an available external 230V supply powers connected loads through the inverter's bypass circuit. If the external supply is interrupted, the inverter automatically transfers to battery operation.
In inverter priority mode, battery power is preferred until the configured battery voltage threshold is reached, after which the unit can transfer to an available mains supply.
This makes the inverter particularly useful for campervan and motorhome installations where both campsite electric hook-up and off-grid battery power are required.

Frequently Asked Questions
Yes. This inverter is designed specifically for 12V DC battery systems and converts stored battery energy into 230V AC electricity. It is suitable for campervans, motorhomes and other off-grid electrical installations with appropriately sized batteries and wiring.
Yes, provided the appliance's operating power and starting requirements remain within the inverter's capabilities. The unit provides 3000W continuous output and can accommodate short-duration surge loads up to 6000W. Battery capacity, discharge capability and cable sizing must also be considered.
Yes. The built-in mains bypass function allows connected appliances to operate from an external AC supply when available. If that supply is interrupted, the inverter can automatically transfer to battery power in less than 10 milliseconds.
No. The SR-IBC12-3kW provides inverter operation and mains bypass functionality but does not incorporate a battery charger. A separate mains battery charger is required if you want to charge your leisure batteries from electric hook-up.
Yes. Bluetooth connectivity is included as standard, allowing operating information and fault conditions to be viewed using a compatible SRNE mobile application.
Yes. It can operate with a suitable 12V lithium battery system, provided the battery voltage range, battery management system (BMS), discharge current capability and installation are compatible with the inverter's requirements.
At full output, a 3000W inverter can draw approximately 290A or more from a 12V battery system, depending on battery voltage and conversion efficiency. High-current cabling, appropriate protection and a battery bank capable of supplying the required current are essential.
Yes. The ECO mode reduces standby power consumption to less than 3W under specified conditions. The inverter can detect electrical demand and resume normal operation when the configured load threshold is reached.
