Charge Controllers

Batteries need protection from excessive charging, and from deep discharge. G-teck offers several charge controllers for the professional market. To quickly charge the batteries the best way possible, is a very challenging task. To meet this demand it takes an advanced 3 (4) step PWM modulated charge controller of high quality.

The Morningstar charge controller ensures the right amount of energy-flow to the battery at any given time. The result is a battery bank of general high state of charge, as well as battery longevity.

Most of the regulators have the following features:
  • Temperature compensation of the charging voltage.
  • Easily adapted to suit different kind of batteries (also NiCad)
  • Protection from deep discharge
  • Low self consumption (1 – 10 mA)
  • Different voltages, 12Vdc – 48 Vac
  • Optional digital display
  • Models with diversion load for regulation of wind or hydro power
  • High quality
  • Models from 4A – 60A
