Cotek SL-2000 Pure Sine Wave Inverter Charger, 2000 Watts, Low Frequency

Price: $975.00

Availability: in stock

Cotek's 12 volt SL models are highly versatile and affordable pure sine wave inverter chargers. Once installed, you can get AC house power, battery charging from grid power, and a pass-through for external AC all in one unit! This is the perfect compliment to a panel or two, guaranteeing you power even on the darkest of days. Low frequency inverters are ideal for larger loads and surges such as a saw or blower motor, as they can sustain large inrush currents better than other models. 


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
  • InverterAC output overload protectionInverter
  • AC output short circuit protection
  • AC input short circuit protection: Breaker (50Amp)
  • 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
