The primary difference is sustained output. The Mastervolt alternator is a standard design high performance alternator. They do deliver a high output for a short period of time, but as soon as they warm up they de-rate to 1/3 of their peak rate performance.
The Integrel generator has been optimised to offer the following
- Software limited at 9kW
- Sustained output ~8kW+
- Diode pack and other sensitive electronics have been removed to an Intelligent controller
- Removing the electronics allows better airflow and cooling, as does the large frame design
- The Intelligent controller:
- can determine if the boat is in gear or neutral and adjusts accordingly
- can be programmed to provide very high output at low RPM
- can be programmed to charge Lithium Ion batteries per a custom charge profile
- contains charge algorithms are altered by
- Engine power output
- RPM
- Temperature
- Engine power curve vs. propeller power curve
The Mastervolt alternator comes as-is with very little flexibility regarding configuration for the above parameters.
