COTEK SL Series SL2000-112 2kW 12VDC 115VAC Pure Sine Wave Inverter/Charger

Manufacturer Part#: SL2000-112

COTEK is committed to providing proactive service, innovative technology and total quality assurance since COTEK was established in 1986. COTEK is a technology-oriented company focusing on developing, designing and manufacturing product.

The COTEK SL2000 inverter/charger is a pure sine wave inverter designed for mobile and renewable energy applications. This powerful charger can be used to recharge your batteries by plugging into 120-volt AC power from either from the grid or a generator. COTEK has integrated several advanced protection features including:

  • DC input over/under voltage protection
  • Internal over temperature, battery over temperature and heat sink over temperature
  • AC output short circuit protection
  • AC input short circuit protection: Breaker (50 Amp)
  • AC input under/over voltage protection

The SL2000 is easy to install and is a good cost-effective option for smaller off-grid and mobile power systems.


  • All in one design: Bi-direction inverter and charger
  • 4 stage charging function with Max. 100A
  • Up to 12KW AC bypass capability (thru 2 legs , 50 Amp each)
  • Intelligent software for power management: Power sharing and generator function
  • Fan controls by load and temperature
  • -20C~40C full load operation without derating
  • UL458 with marine supplement, CSA 22.2, FCC approved
