12 Volts / 350 Watt Water Resistance IP20 Developed for professional duty, the Phoenix range of inverters are suitable for the widest range of applications. The design criteria have been to produce a true sine wave inverter with optimised efficiency but without compromise in performance. Employing hybrid HF technology, the result is a top quality product with compact dimensions, light in weight and capable of supplying power, problem-free, to any load. Microprocessor control provides excellent protection against accidental misuse. Battery cables included. Extra start-up power A 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. The 24/800 model, for example, is capable of starting a typical refrigerator.
