I have had a Sterling for about 7 or 8 years, initially with 200 Ah of battery, for the past season with 300 Ah. Alternator is standard Yanmar 55 Amp. At the beginning of this year I fitted an ammeter, so have been able to monitor current drawn. After a typical night of fridge running the voltage might be down to about 12.2 or 12.3. If we start up the engine early before the solar panels have had a chance to put some back the current is maximum 55 or more (additional from panels) for around 5 minutes, then gradually begins to reduce. Not had a problem with the alternator so far but will remember to test its temperature in the future.
