Phocos SI350-12230



Phocos SI350
Pure Sine Solar Inverter 350W, 12/24V to 110/230V

350Wac Pure Sine Wave off-grid Inverter for 12/24Vdc to 230Vac/50Hz (opt. 110V/60Hz)


This new product line of inverters converts 12V-DC or 24V-DC energy from battery (within an PV Off-Grid system) into clean, stable 110V-AC or 230V-AC power, that is ideal for powering demanding home appliances. Phocos inverters are designed for high efficiency. Integrated advanced microprocessor technology combined with pure sine wave output makes them the perfect choice for use with high-end electronics and electrical equipment. Thanks to their low weight and long lifespan, the SI series is also ideal for mobile and outdoor applications (e.g. RVs, cars, and many more).

An extra advantage: THD < 3 %. As a special, high-performance benefit, Phocos True Sine Wave Inverters offer a THD (Total Harmonic Distortion) of less than 3 percent, providing top performance and superior efficiency. Overload, short circuit, DC over/under voltage, and overheating protection are standard on all models (350/700/1500W). Now, even typical home appliances (supplied from AC outlets) can be powered by small solar home systems (12-48 voltage range).


  • Input/output fully isolated for increased application flexibility
  • Input / output protected against over- and undervoltage
  • Low power saving mode <1 W (350 W) boosts system efficiency and reduces costs
  • Advanced microprocessor optimizes operation processes while reducing energy consumption
  • Certified for mobile applications (RVs, cars, and others)
Please choose one of the available DC input and AC output parameters. Within the SI-350 series are 4 different devices available, separately for specific parameter (12V/110V, 24/110V, 12V/230V, 24V/230V). See product data-sheet.
