The voltages I have quoted are taken from a smartguage which is connected across the battery terminals. I will report back with other suggested readings.

You are correct , I am using a victron multiplus to charge when the TP is on , but with 300 ah of Lifep04 ( 2 x150 ) they are capable of accepting 2x100amp charge , just trying to reduce engine hours / diesel. ( In the winter, summer is not an issue with our solar array 830w.)

90 + amps - voltage = 13.1 ( just after starting b4 TP engaged ) 44 amps - voltage = 13.7 ( after TP engaged ) 10- 20 amps - voltage 13.85 tp 13.95

OK , I will report back.

Hi , I think Nicknorman can answer this - I have a beta 43 ( 2006 long spline cranknose ) fitted with a Travelpower 3.5kva , powering a Victron 12/2500/120 whilst charging. I see about 100amps from the Victron , plus whatever the leisure alternator output , this starts at about 90amps , drops to 50 when the T.P. is switched on, but rapidly falls to 10-20amps. As I have a hybrid LA/ Lifepo4 battery bank ,it can receive up to 200amps no problem, so how can I make better use of the leisure alternator ? I am thinking a Sterling advanced alternator regulator could do it. The L.alternator is a 175amp and rarely gets above 60 deg c.
