We built a better thermostat. engenity’s unrivaled SoliStat 2 is an easy-to-use, all-in-one temperature-controlled switch for DC-powered heating and cooling applications.

  • Switches up to 30 amps of current.
  • Runs on supply voltages from 6 to 24 volts DC.
  • Rugged and weatherproof: works in wet conditions and in temperatures from −40°F to 257°F (−40°C to 150°C).
  • Eliminates failure-prone mechanical components by using a calibrated RTD sensor, microcontroller, and solid-state switch.
  • Unprecedented 5-year warranty.

This table shows the standard available SoliStat models – however, SoliStat is fully customizable and not limited to these configurations. For details on the options available, see our page on customizability.
