Victron Smart IP43 Charger 12V 30A (1+1) 120-240V

The Victron Smart IP43 Charger 12/30(1+1) is a mains-powered battery charger designed for professional and semi-professional use. It accepts a wide input voltage range of 120 to 240V AC, making it suitable for use across the UK, Europe and North America. The (1+1) output configuration provides one main 30A charge output and one dedicated 4A output for a second battery, such as a starter battery.

Key Features

• 30A main charge output for 12V battery banks, with a separate 4A output for a second battery (1+1 configuration).
• Wide AC input range of 120 to 240V makes the unit compatible with UK, European and North American mains supplies.
• Bluetooth built-in via Victron's VE.Smart networking, allowing monitoring and configuration through the VictronConnect app on iOS and Android.
• IP43 rated enclosure provides protection against solid objects over 1mm and against water spray up to 60 degrees from vertical.
• Adaptive 7-stage charge algorithm covers bulk, absorption, float, storage, equalisation and recondition phases for lead-acid batteries.
• Compatible with lithium (LiFePO4) battery chemistries in addition to standard lead-acid types including AGM, gel and flooded.
• Temperature-compensated charging when used with an optional battery temperature sensor, protecting batteries in variable ambient conditions.

Product Overview

The Smart IP43 range sits above Victron's basic Blue Smart chargers in terms of build quality and output capacity. The IP43 enclosure is suited to workshop, vehicle or marine environments where some exposure to dust and moisture is likely. At 30A output on a 12V bank, this charger can handle battery banks up to around 300Ah comfortably in daily use, and larger banks in a maintenance or storage context.

The integrated Bluetooth module connects directly to the VictronConnect app without any additional hardware. From the app, installers and end users can monitor charge state, adjust charge algorithm settings, select battery type and review historical data. The charger also supports VE.Smart networking, which allows it to share battery voltage and temperature data with other compatible Victron devices on the same network, improving charge accuracy across a system.

The second output (the "+1" in the model designation) provides a constant 4A to a secondary battery, typically a vehicle or vessel starter battery. This output is isolated from the main output, so the two batteries are charged independently without risk of cross-discharge. This is a practical feature for motorhomes, boats and commercial vehicles where maintaining a separate starter battery is a requirement.

Installation Notes

This charger connects to a standard mains supply and should be installed by a qualified electrician in accordance with local wiring regulations. In the UK, any fixed mains connection must comply with BS 7671. Ensure the AC supply is protected by an appropriately rated circuit breaker. Battery connections should be made with correctly rated cable and fusing. When installing in a marine environment, follow the relevant standards for electrical installations on boats. If integrating with a LiFePO4 battery, confirm the battery's BMS is compatible with the charger's charge profile before commissioning.
