Description
The ComAp InteliCompact NT SPtM (Single Parallel to Mains) is a specialized controller designed for exactly what the name suggests: a single gen-set running in parallel with the mains (utility grid).
While the “MINT” version is for multiple generators, the SPtM is the “soloist.” It is the go-to legacy solution for small industrial sites or commercial buildings that have one generator and want to perform “no-break” power transfers or peak shaving without the complexity of a multi-gen-set network.
Key Features of the InteliCompact NT SPtM
-
Single-Gen Paralleling: Specialized software optimized for synchronizing one generator to the grid.
-
No-Break Transfer: Ensures that when the grid returns after a failure, the load is shifted back to the utility seamlessly without the lights flickering.
-
Peak Shaving: Automatically starts the generator when the building’s power demand exceeds a pre-set limit, saving on high-tariff utility costs.
-
Mains Protection: Includes built-in voltage, frequency, and vector shift monitoring to protect the generator from grid instabilities.
-
AMF Functionality: Full Automatic Mains Failure logic—it detects a blackout, starts the engine, and closes the breaker automatically.

Critical Buyer’s Guide: InteliCompact NT SPtM
To ensure you get exactly what they need, we emphasize these points:
-
Single Unit Limit: This controller cannot be used for paralleling two generators together. If they have two engines, they need the MINT version or the InteliGen 4 200.
-
No Internal Ethernet: Just like the rest of the NT family, this unit requires a plug-in module (like the IB-Lite) for any network or internet monitoring.
-
Modern Replacement: If a customer is looking to replace a failed SPtM unit, the InteliGen 4 200 is the current-generation replacement. It handles single-parallel-to-mains tasks much more efficiently and with better security.
-
Integrated Display: Includes the classic monochrome screen and physical buttons for “at-the-machine” manual control.
