The Victron Inverter 12/250 is a compact 250VA pure sine wave inverter that converts 12V DC battery power to 230V AC. It suits small off-grid loads, mobile installations and backup applications where a lightweight, reliable inverter is needed without the complexity of a full inverter/charger.

Key features

• Output, 250VA continuous at 230V AC from a 12V DC battery bank
• Waveform, pure sine wave, compatible with sensitive electronics and inductive loads
• Monitoring, VE.Direct port for use with Victron GX devices or the VictronConnect app
• Connection, IEC socket output for direct appliance connection
• Weight, 2.6 kg, suited to space-constrained installations
• Protection, built-in low battery voltage, overload and over-temperature protection

Product overview

The 12/250 sits at the entry level of Victron's VE.Direct inverter range. At 250VA it isn't intended for high-draw appliances, but it copes well with small continuous loads: LED lighting, phone and laptop charging, small fans and low-power tools. Pure sine wave output means it won't cause the issues that a modified sine wave inverter can with switch-mode power supplies or motors.

The VE.Direct interface is what separates this from a basic inverter. It integrates with Victron's monitoring ecosystem, including the Cerbo GX and Color Control GX, giving visibility of inverter status, load and fault conditions through the VRM portal. That makes it a practical choice for small off-grid systems where monitoring still matters.

The IEC output socket takes standard IEC-fitted appliances directly. Protection circuits cover low battery cutoff, overload shutdown and thermal protection, and all reset automatically once the fault clears.

Applications

• Small off-grid cabins or shelters with limited 12V battery storage
• Campervans and motorhomes needing a 230V AC outlet for low-power devices
• Marine installations needing a compact 230V source from a 12V bank
• Backup power for small loads such as routers, lighting or phone charging
• Monitoring-integrated off-grid systems using Victron GX devices

Installation notes

This inverter connects directly to a 12V DC battery bank. DC cable sizing and fusing must be appropriate for the current draw at full load. Installation should be carried out by a qualified electrician or experienced installer. The unit is not grid-connected and does not require G98 or G99 notification, but all AC wiring from the IEC output must comply with BS 7671.
