Blueplanet 3502xi inverter

The KACO 3502xi inverter works longer than the competition.

  • 95.5% CEC efficiency ensures low energy losses
  • Wide MPPT range allows string sizing flexibility with all PV modules and temperature ranges
  • Low start-up voltage more solar power harvest time
  • Newest generation IGBTs and advanced MPPT algorithms

KACO blueplanet Inverter Benefits

  • Pre-wired & separable integrated DC/AC disconnects
  • Connection box directly connects multiple inverters
  • The low start-up voltage allows earlier wake up and longer production than the competition
  • Multiple knock-outs on bottom, sides and back offer great installation flexibility
  • easyINSTALL T-bracket minimizes mounting process to approximately 15 minutes
  • KACO inverters are up to 50% lighter than comparably sized inverters
  • No fan cooling outlets on the sides allows for less side clearance
  • Field selectable voltages allow 208V, 220V or 240V grid settings
