Proven reliability

• The full bridge with toroidal transformer topology has proven its reliability over many years.
• The inverters are short circuit proof and protected against overheating, whether due to overload or high ambient temperature.

High start-up power

• Needed to start loads such as power converters for LED lamps, filament lamps or electric tools.

ECO mode

• When in ECO mode, the inverter will switch to standby when the load decreases below a preset value. It will switch on and check every few seconds, adjustable, if the load has increased again.

Remote on/off connector

• A remote on/off switch can be connected to a two-pole connector or between battery plus and the left hand contact of the two pole connector.

LED diagnosis

• A red and a green LED indicate inverter operation and status of the different protections.

To transfer the load to another AC source: the automatic transfer switch

• For our low power inverters we recommend our Filax Automatic Transfer Switch.
• The Filax features a very short switchover time (less than 20 milliseconds) so that computers and other electronic equipment will continue to operate without disruption.

Available with different output sockets

• Schuko, UK (BS-1363), AU/NZ (3112) or IEC-320 (male plug included)

Installation

Location of the inverter

1. Ceiling mounting (inverted). / Not recommended
2. Base mounting. / OK
3. Vertical wall mounting, fan at bottom. / OK (beware of small objects falling through the ventilation openings on top).
4. Vertical wall mounting, fan on top. / Not recommended
5. Horizontal wall mounting. / OK

For best operating results, the inverter should be placed on a flat surface. To ensure a trouble free operation of the inverter, it must be used in locations that meet the following requirements:

• Avoid any contact with water. Do not expose the inverter to rain or moisture.
• Do not place the unit in direct sunlight. Ambient air temperature should be between -20 ºC and 40 ºC (humidity < 95 % non condensing). Note that in extreme situations the inverter’s case temperature can exceed 70 ºC.
• Do not obstruct the airflow around the inverter. Leave at least 10 centimetres clearance around the inverter. When the inverter is running too hot, it will shut down. When the inverter has reached a safe temperature level the unit will automatically restart again.

Connection to the battery

In order to utilize the full capacity of the product, batteries with sufficient capacity and battery cables with sufficient cross section should be used. See table:

Recommended DC cable cross-section (mm2)
0 – 1,5 m| 4 mm²| 2,5 mm²| 1,5 mm²|  | 6 mm²| 4 mm²| 2,5 mm²
1,5 – 3 m| 6 mm²| 4 mm²| 2,5 mm²|  | 10 mm²| 6 mm²| 4 mm²

Recommended DC cable cross-section (mm2)
0 – 1,5 m| 6 mm²| 6 mm²| 4 mm²|  | 16 mm²| 6 mm²| 4 mm²
1,5 -3 m| 10 mm²| 10 mm²| 6 mm²|  | 25 mm²| 10 mm²| 6 mm²

The inverters are fitted with an internal DC fuse (see table above for rating). If the DC cable length is increased to more than 1,5m, an additional fuse or DC circuit breaker must be inserted close to the battery. Important note: for UL certified (NEMA GFCI) inverters it is mandatory to install a fuse or DC circuit breaker close to the battery, even if the cable length is less than 1,5m.
Reverse polarity connection of the battery wires will blow the internal fuse and can damage the inverter. The internal fuse is not always replaceble (see table above).

Wire size for connecting the inverter chassis to ground

• The earth conductor from the earth lug on the chassis to ground should have at least half the cross-section of the conductors used for the battery connection: see Appendix B.

Connection to the load

• Never connect the output of the inverter to another AC source, such as a household AC wall outlet or a generator.
• The inverter does not have a fuse in the AC output. The AC cabling is protected by a fast-acting current limiter in case of a short circuit and an overload detection mechanism which mimics the characteristics of a fuse (i.e. faster shutdown with larger overload).
• It is important to size your wiring properly based on the inverters’ power rating.

Connecting the inverter neutral output to the chassis/ground

• The AC output is isolated from the DC input and the chassis. Local regulations may require a true neutral.
• In this case one of the AC output wires must be connected to the chassis, and the chassis must be connected to a reliable ground: see appendix A.

Remote on/off connector

• A remote on/off switch can be connected to the two-pole connector. Alternatively, the left-hand contact of the connector can be switched to battery positive: useful in automotive applications, wire it to the ignition contact.
• Note that also the front switch needs to set to either On or ECO for the inverter to start.

Configuration

The inverter is ready for use with the factory settings (see specifications), and can be configured with a computer (VE.Direct to USB interface cable needed), Apple and Android smartphones, tablets and other devices (VE.Direct to Bluetooth Smart dongle needed).

Operation

LED definitions

ECO Mode

Set the front switch to ECO mode to reduce the power consumption in no-load operation. The inverter will automatically switch off as soon as it detects that there is no load connected. It then switches on, briefly, every 2.5 seconds to detect a load. If the output power exceeds the set level, the inverter will continue to operate.

• The default ECO mode wake-up minimum power is 15 Watt.
• The default ECO mode search interval is 2.5 seconds

Note that the required ECO mode settings are heavily dependent on the type of load: inductive, capacitive, non-linear. Adjustment may be needed.

Protections and automatic restarts

Overload

Some loads like motors or pumps draw large inrush currents in a start-up situation. In such circumstances, it is possible that the start-up current exceeds the over current trip level of the inverter. In this case the output voltage will quickly decrease to limit the output current of the inverter. If the over current trip level is continuously exceeded, the inverter will shut down: wait 30 seconds and then restart.

After three restarts followed by another overload within 30 seconds of restarting, the inverter will shutdown and remain off. The LEDs will signal shutdown due to overload. To restart the inverter, switch it Off, then On.

Low battery voltage (adjustable)

• The inverter will shut down when the DC input voltage drops below the low battery shutdown level.
• After a minimum delay of 30 seconds, the inverter will restart if the voltages rise above the low battery restart level.
• After three restarts followed by a low battery shutdown within 30 seconds of restarting, the inverter will shutdown and stop retrying. The LEDs will signal low battery shutdown. To restart the inverter, switch it Off, and then On, or recharge the battery: as soon as the battery has risen and then stays above the Charge detect level for 30 seconds, it will switch on.
• See the Technical Data table for default low battery shutdown and restart levels. They can be changed with VictronConnect (computer or app).
• Alternatively Dynamic Cut-off can be implemented, see https://www.victronenergy.com/live/ve.direct:phoenix-inverters-dynamic-cutoff

High battery voltage

Reduce DC input voltage and/or check for a faulty battery- or solar-charger in the system. After shutting down due to a high battery voltage, the inverter will first wait 30 seconds and then retry operation as soon as the battery voltage has dropped to acceptable level. The inverter will not stay off after multiple retries.

High temperature

• A high ambient temperature or enduring high load may result in shut down to over temperature.
• The inverter will restart after 30 seconds. The inverter will not stay off after multiple retries.
• Reduce load and/or move inverter to better ventilated area.

High DC ripple

• High DC ripple is usually caused by loose DC cable connections and/or too thin DC wiring. After the inverter has switched off due to high DC ripple voltage, it waits 30 seconds and then restarts.
• After three restarts followed by a shutdown due to high DC ripple within 30 seconds of restarting, the inverter will shutdown and stops retrying. To restart the inverter, switch it Off and then On.
• Continuous high DC ripple reduces life expectancy of the inverter.

Mounting instructions

Mount the inverter with four screws vertically up- or downwards or horizontally up- or downwards (as indicated in Figure 1) against a sturdy wall or horizontally on a suitable ground surface (as indicated in Figure 2). Keep at least 4 inches (10 cm) clearance with respect to other apparatus/objects. Beware that IP21 only applies to the lower mounting method depicted in Figure 2; otherwise IP20 is applies. Do not mount the inverter upside down to a surface.

Appendix A

Connecting the inverter neutral output to the chassis/ground

The AC output is isolated from the DC input and the chassis. Local regulations may require a true neutral. In this case one of the AC output wires must be connected to the chassis, and the chassis must be connected to a reliable ground. Inside the inverter a provision has been made to be able to connect the neural and the chassis; the way to do this is explained below.

Please be sure to disconnect the battery when connecting the neutral to protective earth (PE).
An internal PE wire, which is used to connect the neutral and the chassis, is accessible after removing the plastic cover. A Torx T10 screwdriver is needed to loosen the four screws which hold the plastic cover.

In the pictures below the two possible connections of the PE wire are shown:

For the 250 VA, 375 VA and 500 VA inverters:

1. Neutral floating
   • Position of the PE wire (indicated by arrow):
2. Neutral connected to protective earth
   • Position of the PE wire (indicated by arrow):

For the 800 VA and 1200 VA inverters:

• For these inverters the earth wire from the chassis can be either connected to FJ1 (neutral floating) or to FJ2 (neutral connected to earth/chassis).
• The labels FJ1 and FJ2 are printed on the circuit board. The default position is FJ1, i.e. neutral is floating.

Appendix B

Wire size for connecting the inverter chassis to ground

The earth conductor from the earth lug on the chassis to ground should have at least half the cross-section of the conductors used for the battery connection. The maximum conductor size that fits the earth lug is 25 mm². Use the table below to find the correct cross-section for the earth conductor.

Cable cross-section

to battery| to protective earth
1.5 mm²| ≥ 0.75 mm²
2.5 mm²| ≥ 1.5 mm²
4 mm²| ≥ 2.5 mm²
6 mm²| ≥ 4 mm²
10 mm²| ≥ 6 mm²
16 mm²| ≥ 10 mm²
25 mm²| ≥ 16 mm²
35 mm²| 25 mm²
