AC Master 24/2500 inverter (230 V 50/60 Hz, EU Schuko plug)

The Mastervolt AC Master 24/2500 inverter (part number 28022500) is designed to convert a 24 V DC input, typically from batteries, into a 230 V AC output at 50 or 60 Hz. It delivers a pure sine wave, which is critical for safely powering sensitive electronic equipment aboard your boat or vehicle.

The Mastervolt AC Master 24/2500 inverter delivers a continuous power output of 2500 W at an ambient temperature of 40 °C. It can handle peak loads up to 3000 W for 3 seconds and up to 4000 W for 0.2 seconds, which is useful for devices requiring high start-up current.

This inverter produces a pure sine wave. This waveform is identical to that of the domestic power grid and is ideal for powering all types of electronic devices, including the most sensitive ones, without risk of damage or malfunction. Typical harmonic distortion is less than 5%.

The Mastervolt AC Master 24/2500 inverter requires a nominal DC input voltage of 24 V. It is designed to operate with 24 V battery systems.

The inverter provides an AC output voltage of 230/240 V (± 3 %) and a frequency of 50/60 Hz (± 0.1 %). These parameters can be adjusted using DIP switches 1 and 3 located on the device.

The efficiency of the Mastervolt AC Master 24/2500 inverter is 88%. This means that 88% of the input DC power is converted into usable AC power, with the remaining 12% lost as heat.

For the AC Master 24/2500 inverter, the minimum recommended cross-section for the DC input cables is 50 mm². Using adequately sized cables is critical to ensure safe and efficient operation.

The ground terminal of the AC Master chassis must be connected to the central ground point of the vehicle or boat. Proper grounding is essential for the safety and correct operation of the device.

The Mastervolt AC Master 24/2500 inverter is equipped with multiple protections to ensure system safety and durability, including:

Over-temperature protectionOverload protectionShort-circuit protectionBattery low/high voltage protectionAC overcurrent protection (via circuit breaker)

Yes, the AC Master 2500/3500 (including the 24/2500) allows parallel configuration with 2 to 15 identical units to increase output power. When creating a multi-unit system, it is imperative to use only identical AC Masters with the same part numbers and to ensure that one unit is configured as the master.

The AC Master 24/2500 inverter can be remotely controlled. It has a port offering two functions: a remote switch and a CAN termination jumper. Control can be performed via an LCM port or the DIP switches. In a multi-unit system, the remote switch must always be connected to the master unit.

The energy-saving mode reduces battery consumption when no load is detected. The inverter scans the output and switches to energy-saving mode if the detected load is below a threshold value. It reactivates if the load is approximately 2 to 3 times higher than the threshold. This mode is enabled by setting DIP switch 7 to '0', and the threshold value is adjusted using DIP switches 4, 5, and 6. It is not available in master/slave mode.

The Mastervolt AC Master 24/2500 inverter is equipped with a European (Schuko) AC output socket. It also allows for hardwired connection for fixed installations.

The DIP switches on the Mastervolt AC Master 24/2500 inverter allow configuration of several important parameters:

DIP Switch 1: Sets the AC output voltage (230 V or 240 V).DIP Switch 3: Sets the AC output frequency (50 Hz or 60 Hz).DIP Switches 4, 5 and 6: Sets the energy-saving mode threshold value.DIP Switch 7: Selects energy-saving mode or master/slave mode.DIP Switch 8: Selects LCM remote control or DIP switch control. Always disconnect all DC and AC power sources before changing DIP switch settings.
