Heat King 450 MAX Solar Panel

Solar Benefits on a Heat King

A ThermoLite® 40W solar panel comes standard on all Heat King models to offer:

  • Increased battery life: Keeping batteries charged year-round will negate failure from extended periods of low charge levels and proliferation of sulfation.
  • Fuel savings: Reduce load on the engine with alternator working less and reduced cycle-sentry operation.
  • Extended component life: Run time is reduced, alternator offloading and reduced starter engagement
  • Improved employee efficiency: Cut time spent managing low battery alarms and battery breakdowns.
  • Optimized telematics: TracKing can operate 24/7 without risk of depleting the battery.
