I have read that this system could potentially damage the front end of engine i.e. side loads on crank shaft bearings? I’d be interested to hear your comments on this (my engine will be a Volvo D2 55hp). :

This information is NOT correct. The following extract is from letter received from Volvo France confirming that the load from Integrel is within the engine's tolerances.

We have also conducted independent testing with Rolls Royce Royce labs where, after a series of 1,000 engine hours, we dismantled the engine, removed the crankshaft and bearings. Results showed no discernible abnormal wear on the engine than in normal operation.

Extract from a letter we received from Volvo Penta, France:

We, Volvo Penta Europe Office France, authorize the installation of the Integrel 48V generator on our range of compact D2 50/60/75 engines, according to data provided by the manufacturer:

Peak electrical power output: 9kW
Maximum mechanical power at the crank at 3200rpm: 13.6kW
Electrical power at 1400rpm: 7,5kW
Mechanical power at the crank at 1400rpm: 9kW
Maximum torque at the crank (occurs at 1400rpm): 62Nm

Wishing you good reception,
