Developed for professional duty, the Victron Energy Phoenix Inverter is suitable for the widest range of applications. The design criteria is to produce a true sine wave inverter with optimized efficiency but without compromise in performance. Employing hybrid HF technology, the result is a top quality product with compact dimensions and light weight that's capable of supplying power, problem-free, to any load. Extra Start-Up PowerA unique feature of the SinusMax technology is very high start-up power. Conventional high-frequency technology does not offer such extreme performance. Phoenix inverters, however, are well suited to power up difficult loads such as refrigeration compressors, electric motors, and similar appliances. Virtually Unlimited PowerParallel 3-phase and split phase operation capability provide virtually unlimited power. Up to 6 units inverters can operate in parallel to achieve higher power output. Six 24/3000 units, for example, will provide 15 kW / 18 kVA output power. Operation in 3-phase or split phase configuration is also possible. Automatic Transfer SwitchTransfer the load to another AC source with the automatic transfer switch. If an automatic transfer switch is required it's recommend to use the MultiPlus inverter/charger instead. The switch is included in these products and the charger function of the MultiPlus can be disabled. Computers and other electronic equipment will continue to operate without disruption because the MultiPlus features a very short switchover time (less than 20 milliseconds).Computer InterfaceAll models have an RS-485 port. All you need to connect to your PC is the Victron Energy MK3-USB VE. Bus-to-USB interface (sold separately). Together with VEConfigure software, which can be downloaded free of charge, all parameters of the inverters can be customized. This includes output voltage and frequency, over and under voltage settings, and programming the relay. This relay can, for example, be used to signal several alarm conditions or to start a generator. The inverters can also be connected to VENet, the new power control network of Victron Energy, or to other computerized monitoring and control systems.
