Victron Energy Inverter Smart 3000VA, 12/3000, 24/3000 and 48/3000 230V12V, 24V or 48V 3000VA sine-wave inverter with Bluetooth

Overview

Three battery voltages are offered for the 3000VA Inverter Smart: 12/3000 (PIN122300000), 24/3000 (PIN242300000) and 48/3000 (PIN482300000). All give 2400W continuous at 25°C, 2200W at 40°C and 6000W peak, enough to start compressors and power tools; efficiency is 93%, 94% and 95%. The 12V unit measures 533×285×150mm, the 24V and 48V units 485×285×150mm, all 19kg. Victron calls for 400–1200Ah and a 400A fuse on 12V, 200–700Ah and 250A on 24V, 100–400Ah and 125A on 48V.

• 1600VA to 5000VA continuous at 25°C
• Full bridge and toroidal transformer, peaks up to 10000W
• Built-in Bluetooth plus VE.Direct port
• ECO mode with adjustable wake-up and shutdown power
• Programmable relay and two-pole remote on/off connector
• Single units only: no parallel or three-phase operation

How it works

The Inverter Smart turns the DC of a 12V, 24V or 48V battery bank into a 230V sine wave, adjustable from 210V to 245V at 50Hz or 60Hz. Victron uses a full-bridge stage with a toroidal transformer, which gives the surge capacity needed by motors, LED drivers, halogen lamps and power tools. The unit is short-circuit proof and shuts down on overload, battery voltage too high or too low, overheating, 230V fed back to its output and excessive DC ripple, restarting automatically within set limits.

In ECO mode the inverter drops to a search state when the load falls below the shutdown level (default 50VA) and pulses the output every 3s to look for a load above the wake-up level (default 60VA); Victron quotes about 85% lower no-load consumption. Low-battery shutdown, restart and charge-detect voltages are adjustable, and an optional dynamic cut-off lowers the shutdown voltage as discharge current rises, which mainly benefits OPzS, OPzV, gel and AGM banks.

Installation and compatibility

The inverter hangs on the supplied wall bracket in vertical position; horizontal mounting is allowed but cools less well. It needs a dry, ventilated place close to the battery, never directly above it, with 10cm free all round. There is no internal DC fuse: the manual gives an external fuse, cable section and battery capacity for every model, for example 60A, 16mm² and 75–200Ah for the 48/1600, or 400A and 400–1200Ah for the 12/3000. Battery bolts are M8, tightened to 11Nm at most.

The AC neutral is bonded to the chassis at the factory, so a residual current device on the output works; the link can be moved for a floating output. The chassis earth conductor must be at least half the battery cable section. Units cannot run in parallel or three-phase. To switch loads to shore power or a generator Victron points to the Filax2 transfer switch or to an inverter/charger. The remote connector accepts a switch, an ignition signal or a lithium BMS.

Monitoring and settings

Every setting is made in the VictronConnect app over the built-in Bluetooth, or through the VE.Direct port with a VE.Direct to USB interface: output voltage and frequency, ECO levels and search interval, low-battery thresholds, dynamic cut-off curves and relay mode (inverter, alarm, low battery, fan or off), plus firmware updates. With a VE.Direct cable the inverter appears on a Cerbo GX or other GX device, or on a GlobalLink 520, for remote monitoring in the VRM portal. The Inverter Control VE.Direct panel adds a wired on/off switch.
