HiQ TS208-5k75 Inverter Applications

Ground mount or rooftop commercial; TrueString inverters are usable where other solutions just won’t work - for example salty/moist coastal, hot desert and high altitude locations.

Solar carports/parking and shade structures; units may be mounted at any orientation, under modules, on racking without extra strengthening. This can place them clear of risk of liability from vandalism.

Designed for reliability

  • Robust system with NEMA 6 rated inverter, sealed and waterproof
  • Electrolytic capacitors are used in almost all inverters, and are a known source of long-term failure; we don’t use electrolytics, eliminating a common cause of issues
  • Distributed architecture ensures that if a problem did occur, only a small section of modules would be affected
  • Easy-swap replacement, plug & play means just unplug the connectors, plug in a new one, and the system sorts out the rest
  • Maintenance free - no fans, completely sealed
  • Included 10 year warranty may be optionally extended to 25 years
