Phoenix Inverter 1200–5000 VA

Classic Victron sinewave inverter with VE.Bus port: the Compact 1200, 1600 and 2000 VA series for 12 and 24 V, plus 3000 VA models (12/24/48 V) and 5000 VA models (24/48 V). SinusMax technology provides high starting power, and via VE.Bus the inverters can be connected in parallel and in a three-phase system.

What it is for

Pure 230 V sine wave from the battery

Phoenix Inverter converts 12, 24 or 48 V battery voltage into a pure 230 V sine wave. The manufacturer describes it as an inverter for professional applications: hybrid HF technology gives small size and weight, while SinusMax provides very high starting power, allowing the inverter to start demanding loads such as fridge compressors and electric motors.

The VE.Bus port lets you connect up to six identical inverters in parallel or build a three-phase system (star only), and connect a panel, GX device or computer to change settings.

  • Compact 1200, 1600 and 2000 VA series for 12 and 24 V,
  • 3000 VA models (12, 24, 48 V) and 5000 VA models (24, 48 V),
  • without a charger and without a source transfer switch — for that there is MultiPlus or Quattro.

Features

What the Phoenix Inverter can do

SinusMax — starting power

Peak 2,400 W (1,200 VA) to 10,000 W (5,000 VA). The manufacturer emphasises that conventional HF technology cannot provide such reserve power.

Parallel and three-phase

Up to six identical inverters in parallel — six 24/5000 units give, according to the datasheet, 24 kW / 30 kVA. Three-phase system only in star (Y); delta is not supported; Compact also allows split-phase.

VE.Bus

Inverter Control panel, GX device (for example Cerbo GX) for monitoring and VRM, VE.Bus–NMEA 2000 interface, and via MK3-USB — a computer with VictronConnect or VEConfigure.

Programmable relay

Alarm as standard (also for pre-alarms). You can set it, for example, to start a generator. Rating: AC 230 V / 4 A, DC 4 A up to 35 V and 1 A up to 60 V.

AES mode

Automatic Economy Switch reduces no-load and light-load consumption by about 20%, slightly “narrowing” the sine wave. In 3,000/5,000 VA units it is enabled with ds5; in Compact — only from a computer. It works in single operation.

Search mode

Reduces no-load consumption by about 70%: the inverter switches off and checks every 2 seconds whether a load has appeared. By default it switches off below 40 W and stays on from 100 W. In Compact it is enabled with ds6; in 3,000/5,000 VA units — from a computer.

Protections a–g

Short circuit and output overload, battery voltage too high and too low, temperature too high, 230 V fed to the output and excessive ripple on the DC input.

−40 to +65 °C

Fan cooling, humidity up to 95% non-condensing. Continuous power decreases with temperature — for example, 3,000 VA: 2,400 W at 25 °C, 1,700 W at 65 °C.

Output regulation

Voltage 210–245 V and frequency 50 or 60 Hz — 230 V / 50 Hz as standard. The most important settings are changed with DIP switches, all settings — from a computer.

Installation

Where and how to install

Qualified electrician only

The battery is a permanent energy source — even a switched-off inverter may have dangerous voltage at the terminals. Before work, switch off AC and disconnect the battery. There are no user-serviceable parts inside; do not operate the unit without the covers fitted.

Protection class I — earthed enclosure

Connect the enclosure to earth, the vehicle chassis, or the grounding plate or boat hull. If you suspect an earth fault, the unit must be switched off and protected against being switched on again.

  • A dry, ventilated place as close to the battery as possible, with at least 10 cm of free space around it. Never in a damp, dusty or gas- or dust-explosion-hazard area.
  • Wall mounting — rear hook and two holes; vertical or horizontal, vertical cooling works better. The interior must remain accessible after installation.
  • Heat-resistant surroundings: no chemicals, plastics, curtains or fabrics nearby. Never directly above batteries.
  • For transport and storage, disconnect the battery cables; store between −20 and +60 °C, in a dry place.
  • DC and AC cables with fuses and switches; replace protection devices only with the same type.
  • On Compact units, reverse battery connection damages the unit (it may blow the internal fuse).

Do not lift heavy models on your own. 3000 VA weighs 18 kg, 5000 VA — 30 kg. Access to the terminals is gained by removing the four screws of the front panel.
Parallel and three-phase operation

Up to six identical inverters of the same power; DC cables of the same length and cross-section, at least 10 cm clearance below, above and beside each unit. UTP cables directly from unit to unit (and to the panel), with no splitters. In the system, only one panel or one remote switch. Three-phase system — star (Y) only.

Settings

DIP switches and computer

3000 and 5000 VA models

By default, the inverter is set for single operation: 230 V, 50 Hz, AES off, relay — alarm. The most important settings are changed with DIP switches, all settings — from a computer (VEConfigure3 via the MK3-USB interface). Parallel and three-phase operation is configured with software: up to three inverters — VE.Bus Quick Configure, from four onwards — VE.Bus System Configurator.

  • ds5 — AES: off = disabled, on = enabled (single operation only).
  • ds4 — voltage: off = 240 V, on = 230 V.
  • ds3 — frequency: off = 60 Hz, on = 50 Hz.
  • Save: with the inverter switched on (preferably with no load), hold the “Up” button for 2 s — the “overload” and “low battery” LEDs will flash. ds8, ds7, ds6, ds2 and ds1 remain in the off position.

Firmware. This manual applies to version xxxx400 or later. Older units can be updated if the 7-digit number starts with 26 or 27; if it starts with 19 or 20 — it cannot. In xxxx1xx firmware, ds1 and ds2 are used to set single, parallel or three-phase operation. For parallel operation, the easiest option is to set all inverters identically.

DIP under the front panel. In 3000/5000 VA models, the switches and the “Up” button are on the board inside; the switches can be left in the set position so the settings can be reproduced.

ds1, ds2control method: ds1 off / ds2 on — switch on the enclosure (factory default; also with GX or VE.Bus Smart dongle without a panel); ds1 on / ds2 off — Multi Control panel or VE.Bus BMS; ds1 off / ds2 off — remote 3-position switch
ds5frequency: off — 50 Hz, on — 60 Hz
ds6Search mode: off — disabled (factory default), on — enabled
ds8save: switch from off to on and back to off — the three LEDs flash four times

On the Compact, output voltage and AES are set from a computer or a VE.Net panel. The factory settings were written by software, so in a new unit all switches except ds2 are in the off position and do not reflect the settings.

Diagnostics

What the LEDs mean

3000 and 5000 VA models have four LEDs: “inverter on”, “overload”, “low battery” and “temperature”. Below are the situations from the fault table in their manual. Error codes for parallel and three-phase systems: VE.Bus errors; the Victron Toolkit app also shows the current codes by flashing.

Will not start after switching on

Battery voltage too high or too low, or no voltage at the DC terminals. Check the battery voltage and connections.

“low battery” flashes or stays on

Flashing: low battery voltage. On: the inverter has shut down due to low voltage. Charge the battery and check the connections.

“overload” flashes or stays on

Flashing: the load exceeds the rated power. On: the inverter has shut down due to overload or short circuit. Reduce the load.

“temperature” flashes or stays on

Ambient temperature too high or load too large. Move the inverter to a cooler, well-ventilated place or reduce the load.

“overload” and “low battery” flash alternately

Low battery and too much load. Charge the battery, reduce the load, use a larger battery or shorter, thicker cables.

“overload” and “low battery” together

Flashing — ripple at the DC terminals above 1.5 V rms (3000/5000 VA); on — the inverter has shut down for this reason. Check the cables and battery capacity, then switch the inverter off and on.

“inverter on” flashes in a VE.Bus system

Together with a flashing “overload” LED, this is an OK code — the unit is healthy and waiting for the others. A flashing “inverter on” LED on its own with the system switched off is a VE.Bus error, for example a damaged UTP cable. Switch off all devices, check the wiring and switch on again. You can read the details with VE.Bus System Configurator or Quick Configure.

“overload” and “low battery” flash after saving

This is how the inverter confirms that the DIP switch settings have been saved (the “Up” button for 2 s) — it is not a fault.

One alarm LED is on, the other is flashing

The LED that is on indicates the alarm that caused the inverter to shut down; the flashing LED indicates the alarm that would have caused it to shut down next.

Compact series — three LEDs: “inverter”, “eco mode” and “alarm”

“inverter” is on

The inverter is on and supplying the loads from the battery.

“eco mode” is on

The inverter is operating in energy-saving mode and supplying the loads.

The three LEDs flash four times

Confirmation that the settings were saved with the ds8 switch — this is not a fault.

“alarm” flashes

Early warning: low battery voltage, high temperature, overload or ripple at the DC input above 1.25 V rms. Charge the battery, cool the inverter or reduce the load, and check the cables.

“alarm” is on

The inverter has shut down after an early warning — check which cause occurred.

Will not start after switching on

Battery voltage too high or too low — or the processor has frozen: switch the enclosure switch off, wait 4 seconds and switch it back on.

Questions

Frequently asked questions about Phoenix Inverter

Will Phoenix Inverter switch loads to mains?

No — it has no transfer switch or charger. If you need an automatic transfer switch, the manufacturer recommends MultiPlus or Quattro: they switch in less than 20 ms, and their charger can be disabled.

How many inverters can I connect in parallel?

Up to six identical units of the same power rating. The datasheet gives an example: six 24/5000 units make 24 kW / 30 kVA. The inverters can also be connected in a three-phase system — star only — and the Compact series also in split-phase. All units should have identical settings.

Which fuse and cable for 24/3000?

300 A fuse, 50 mm² cable per pole for lengths up to 5 m and 90 mm² for 5–10 m. Recommended battery: 200–700 Ah.

What is different about the Compact series?

These are 1200, 1600 and 2000 VA models for 12 and 24 V in a smaller enclosure. The 1200 and 1600 VA models come with 1.5 m battery cables and a G-ST18i plug on the output, the 2000 VA model has M8 screws and a spring terminal. They also have VE.Bus, parallel operation and three-phase operation.

How can I reduce no-load current consumption?

AES mode reduces it by about 20%, and Search mode by about 70%: the inverter switches off with no load and checks every 2 seconds whether something has switched on. In the 3000/5000 VA models, AES is enabled with switch ds5 and Search with the computer; in the Compact, it is the other way round: Search is switch ds6, AES is the computer. Both work only in single operation.

Can I change the voltage to 240 V or 60 Hz?

Yes. In the 3000/5000 VA models, switch ds4 selects 230 or 240 V, and ds3 — 50 or 60 Hz. In the Compact, switch ds5 changes only the frequency, and the voltage is changed from the computer. From the computer, voltage is set in the range 210–245 V.

How do I connect the inverter to Cerbo GX?

Use an RJ45 UTP cable to the VE.Bus socket. GX provides monitoring and the VRM portal. To change settings from a computer, you need the MK3-USB interface.

Do I need an RCD for Phoenix Inverter?

The output neutral conductor is connected to the enclosure specifically so that the residual current device (RCCB) fitted on the inverter output will operate. The enclosure must be earthed or connected to the vehicle chassis or hull.
