Introduced in 2008, the Princeton Power Systems' GTIB-100 was the first bi-directional inverter designed for advanced batteries, solar, on-grid and off-grid applications. The GTIB-100, is our flagship product and has been chosen for best in class microgrid applications around the world for the past five years.


  • Bi-directional
  • Demand Response
  • Peak Shaving
  • Island Mode
  • Demand Dispatch
  • Frequency Regulation


With 97% efficiency, the GTIB has built-in MPPT for solar arrays and high round-trip efficiency for battery charging.

  • Peak Efficiency: 97% (PV to Grid)
  • CEC Efficiency: 94.5% (PV to Grid)

The GTIB is compatible with advanced communication protocols including MODBUS RTU. The GTIB offers a wide input voltage range and EV Fast-Charging options. Wide DC input voltage range offers flexibility when selecting DC sources such as batteries and PV arrays.
