  • The Best Overall Value – Combination of performance, features and competitive price results in the best controller value on the market.
  • Extremely High Reliability – Failure rates of less than 2 per 1,000 units.

  • No Need to Derate – Designed with a 25% safety margin, controllers may be used up to their full “nameplate” ratings.
  • Expected 15 Year Life – Controllers carry a full 5-year warranty, with an expected operating life of 15 years or more. SHS™ controllers and our Sure Sine inverter carry a two-year warranty.
