Victron MultiPlus 12/500/20-16 230V

The MultiPlus 12/500/20-16 (PMP121500000) from Victron Energy delivers 500W continuous power at 230V and 50Hz. In addition to the sine wave inverter, which converts the 12V DC voltage of your battery into a perfect 230V AC 50Hz sine wave voltage, the Multi 500 is also equipped with a 20A battery charger and a 16A transfer switch. This makes it very interesting for a wide range of applications, and at a comparatively very affordable price.

Key performance features of the Multi 12/500/20

• 500W continuous power and 900W peak power for 12V battery voltage
• Device combination of sine wave voltage converter, 16A transfer switch, and 20A battery charger delivers pure 230V sine wave voltage and a clean 50Hz frequency
• can be used as a UPS solution for uninterruptible power supply thanks to the transfer switch
• can be used for grid-connected self-consumption systems that only draw power from the grid operator when the battery capacity is no longer sufficient or other programmable events have occurred
• programmable relay
• proven quality and reliability
• offers solid protection against overload and overheating
• versatile use in mobile and stationary applications
• can also be used for highly sensitive electrical devices
• can be used in UPS solutions
• VE.Bus connection

Programmable relay

The Multi 12/500/20 has a programmable multifunction relay that operates as an alarm relay in its default setting. However, this relay can be programmed for a variety of additional functions, such as a start relay for a generator.

Control and remote operation

Configuration is carried out via a 3-position switch (DIP switch) directly on the Multi. The maximum load current of the AC input can be set.

Lightning-fast, automatic 16A transfer switch

In the event of a power failure or when the generator is switched off, Multi immediately switches to inverter mode and supplies the connected consumers. This happens so quickly (in less than 20 milliseconds) that computers and other electronic devices continue to operate without interruption (uninterruptible power supply – UPS functionality).

Powerful, 4-stage battery charger
Adaptive 4-stage charging characteristics: Constant current ("bulk") phase, constant voltage ("absorption") phase, charge maintenance voltage ("float") phase, storage voltage ("storage") phase

The microprocessor-controlled battery charging system can be adapted to different battery types. The charging process is adjusted via adaptive control of battery usage.

Other highlights of the built-in charger include:

• variable constant voltage time
• 2 DC outputs for charging the on-board and starter batteries
• Extended battery life through temperature compensation
• less battery aging thanks to integrated storage mode
• less harmful gas formation thanks to battery protection mode

For a detailed description of the charger's features, please refer to the operating instructions, which can be found under "Downloads" above.
Backup system: AC power even during a power outage

The Multi 500 can be used in off-grid applications as well as in grid-connected PV systems and alternative energy systems. Software is available to detect a power failure.
