COTEK SD Series Power Inverters

The SD series is a pure sine wave (THD < 3%) inverter designed especially for the most demanding mobile and off-grid applications. SD series provides up to 90% of high efficiency and wide operating temperature range (from -20°C~+50°C) designed for many harsh environments.

The N+X parallel redundancy framework design can greatly improve the power system’s flexibility and thus the system’s volume and weight are remarkable reduced. SD series features a built-in transfer switch and synchronized operation with utility AC source. SD series can be used for N+1 (N≦14) redundancy and the ability of enlarge the capacity (Users can install maximum 15 units of inverters together in parallel in order to provide the power expansion).
