Cotek Pure Sinewave Inverters

Click here to read more on how to select an inverter. Before choosing an Inverter for your needs, we recommend you read this page and note the definitions explained. This will help you understand why certain Inverters cost more and others less. These definitions can apply to all makes of Inverters whether they are supplied by us or not.

Cotek S Series

Offering superior quality pure sine wave output, the Cotek S series stand-alone inverters are available in 12/24/48V models from 150 to 1500 watts. They are ideally suited for electrical systems that already have a quality battery charger. Designed for industrial and recreational applications, their AC power output is capable of handling both heavy duty and smaller, multiple AC loads.

Cotek SK Series

The compact Cotek SK inverters are available in 12/24/48V models from 200W all the way up to the large and powerful 3000W pure sine wave power inverter. Built-in multistage power-saving control helps save your battery power for when you need it the most. Offering quality pure sine wave output, the SK series of stand-alone inverters are ideally suited for electrical systems that already have a quality battery charger.

Cotek ST Series

Cotek's ST inverters are available in 12/24/48V models from 600 to 2500 watts. Designed for fleet, utility and emergency vehicles to run tools, lights and equipment, the ST inverters feature power-saving functions and integrated automatic AC transfer switch that reacts in less than 14 msec. keeping mission-critical systems online. When not in use, the inverter enters power save mode, reserving battery power for when you need it the most.

Cotek SP Series

The latest SP series pure sine wave inverter from Cotek is available from 200W ~ 4000W and implements the state of art design topology with the following advanced functions: wide DC input voltage / wide operation temperature to fulfill the majority of applications; Low profile and stylish ID design with output voltage selectable dip switch (100/110/115/120 or 200/220/230/240 Vac). Extremely user friendly.

Cotek SD Series

Cotek's Parallel SD inverters are available in 12/24/48V models from 2500W to 3500W. Parallel design for power expansion. Automatic master mechanism to eliminate single point failure and optimize reliability. Built-in ATS and AC circuit breaker.

Cotek SE Series

The Cotek range of SE sinewave inverters have been designed to meet industrial and domestic needs. They satisfy the highest demands of comfort, safety and reliability. Any device designed for the public electrical network can be connected to them. The SE inverters are the perfect solution as sources of tension in any place where the public network is not available. In addition to its modern design and technical characteristics, the SE inverter is also easy and economical to use in almost all applications.

Pure Sinewave Inverters

This is the best output waveform you can get out of an inverter and all appliances are able to run off it without interference or overheating. Some of its advantages are as follows:

  • Output voltage waveform is pure sine wave with very low harmonic distortion and the same as the ESKOM supply
  • Inductive loads like microwave ovens and motors run correctly, quieter and cooler
  • Reduces audible and electrical noise in fans, fluorescent lights, audio amplifiers, TV, Game consoles, Fax, and answering machines
  • Prevents crashes in computers, unreadable print outs, and glitches and noise in monitors
  • It can be efficiently electronically protected in overload, overvoltage, undervoltage and over temperature conditions


Cotek remote controls provide more convenience while using Cotek DC-AC Power Inverter. Cotek remote controls work best with S1500 , SK series , ST series, and SR inverters. You can monitor the inverter performance at a glance, from everywhere at your home, boat, or RV. The LED display panel provides inverter power on, input/output and load status.
