CE+T America’s Twin Sine Inverter Technology (TSI) is a revolutionary design concept that improves overall system reliability, performance and efficiency. Its scalable architecture and dual power input configuration eliminate the Single Point of Failure found in systems using traditional designs.


Designed for critical power applications the reliability and continuity of service are enhanced:
  • The TSI concept eliminates the greatest Single Point of Failure common to conventional systems.
  • The TSI concept is more Energy Efficient when compared to all other technologies without diminishing performance and protection.
  • Each TSI module can utilize both DC and AC sources to support load. While traditional inverters can only use a DC source such as a battery system, the TSI provides a redundant source of supply being able to transfer seamlessly to and from building power without disturbance to the critical downstream AC loads. The TSI provides Filtered AC Main power rather than raw unconditioned supply.
  • The TSI ‘Boost’ has built in Overload Capabilities Assuring AC Distribution Selectivity thus assuring maximum service to your facility.
  • Modular Inverters are paralleled to support capacity or redundancy requirements. Users can custom configure their system to efficiently meet their AC power needs. Modules are hot-swappable and can be added only when demand requires, without disruption to their system. This Scalable Architecture provides for “grow on demand” flexibility.
  • The Compact Size – High Power Density per module of each TSI equates to effective use of floor space within your facility.

Patented protected, TSI technology is designed for varied market applications and can be configured for multiple system platforms.


No Single Point of Failure:
Traditional inverter systems require a system Static Transfer Switch (STS) to act as a means to transfer to AC supply in the event of failure. The challenge with this architecture is that this STS becomes the single power path to your load and thus becomes your potential weak link in providing power to your critical loads. Each TSI inverter has an individual source connection to AC which eliminates the need for a system STS. Each module has the ability to remove itself from the system should it fail, and each module can operate as part of a bypass of AC power to your load. Unlike traditional STS’s; the TSI AC power path provides conditioned and regulated power while operating in this mode.


Energy Efficient:
TSI technology reduces system energy losses by more than 60% over traditional products without compromising output power regulation. Conventional Rectifier/Battery/Inverter systems operate at or around 85%. The TSI with its “Enhanced Power Conversion” (EPC) mode delivers reliable power in an unmatched rate of 95% efficiency.

Energy savings gained from the application of TSI are compounded when you combined the actual power (kW/hr) costs and the reduced cost of cooling . These costs are critical to the fiscal performance and the environmental impact of your business.


Filtered AC Mains:
Each TSI module provides your critical load protection from harmonics, spikes, surges and of course outages. Conventional Inverter systems utilizing a STS provide a direct connection from AC supply to your load therefore exposing your power sensitive facilities to the normal disturbances that occur when powered by commercial utility or generator supply. This exposure can cause disruption to your operation and, worse, damage.

The unique TSI concept and its protection afford you:
  • Unity Power Factor on AC input – it filters out the Harmonics therefore increasing PF
  • AC Power Filtering and conditioning – full sine wave output to your load
  • Compensation for Input Power Sags / Surges without drawing energy from your DC supply – protecting your DC system from unnecessary and life reducing short duration hits



Overload Capabilities Assuring AC Distribution Selectivity:
Properly designed distributions have the trip settings of circuit breakers set to allow for the device closest to the source of an overload condition, to interrupt at that point to isolate this type of fault while minimizing the extent of the disruption this causes. Allowing a short circuit or fault condition too far upstream from the source could unnecessarily cause disruption of service to a much larger section of your operation.

The TSI modules has an internal ‘Boost’ feature that can provide up to 10x the nominal current required to allow a short duration overcurrent situation to be isolated downstream. This ‘Boost’ requires no additional energy from the TSI’s upstream supply thus the breaker ahead of your inverter system is not exposed to this overcurrent and thus remains closed, allowing your properly coordinated breaker system to interrupt closest to the problem while maintaining the maximum amount of service to the rest of your distribution system.

The TSI 'Boost' provides:
  • Internal energy release to allow the downstream device to act and isolate closest to the source of a fault
  • Internal energy release without exposing upstream devices to the overcurrent thus keeping them in service longer
  • Energy necessary to allow your properly coordinated distribution system to act safely and properly in protecting your facility and assuring maximum service



Scalable Architecture:
Most businesses are expected to project demand well in advance of need. This means that businesses are either under-sizing or over-sizing their power framework in anticipation of future plans. Not guessing correctly here could impact your ability to grow and hence limit the expansion of your business. Common systems require you to compensate by either over-sizing your inverter system or the Static Bypass Switch (STS) within your system. Neither of these are required with the TSI as the modules are truly scalable and they have eliminated the need for a system STS.

Compact Size - High Power Density:
Space management is key for all businesses, especially those that are growing. The power density per module as integrated in to your overall system adds up to more power per square foot of physical floor space that may better be utilized in support of your business operation.
