Cotek's SD series are pure sine wave (THD < 3%) inverters designed especially for harsh mobile and off-grid environments. The SD series provides up to 90% efficiency, throughout an extreme operating temperature range (-4°F~+122°F). The N+X parallel redundancy framework design can greatly improve your power system's flexibility, so the overall system volume and weight can be reduced. SD series inverters feature a built-in transfer switch and synchronized operation with utility AC power, and can be used for N+1 (N≦14) redundancy, with the ability to expand the system to include up to 15 SD inverters in parallel.
The SD3500 inverter is rated for 3500 watts of continuous power, with a 6000W surge capacity. Dimensions (WxHxD): 11.4" X 5.05" X 17.17 inches
