Hello Jason,
well, if you want to make dead sure that the charger is handling the additional fridge load while correctly charging your battery, what better chargers are there than the ones designed by the fridge makers themselves....
I'm talking about Waeco chargers.
And the beauty is, although they are powerful 25A units, you save big time compared to the other brand mentioned.
But before you
check out my profile for more info, may I suggest looking into solar to augment your boost/float charging with one or two 25A chargers in parallel.
That way you don't have to run the gennie for long periods of time.
Looking at your load requirement of around 2 amps average, you'll be using 96Ah over a 48 hour period, minus around 50Ah from a 100W or 120W solar panel, leaving about 50Ah for the gennie to put back into your batteries.
That's roughly 25% DOD for 2x100Ah, so you'd run your gennie every second morning for 1 hour (based on 2x25A chargers in parallel).
The solar panel will top off the charge to 100% during the rest of the day.
If only one 100Ah battery and one 25A charger are to be used, and no solar panel, you're looking at a 50% DOD per 24hr, and a daily gennie run time of at least 3 hours. But even then, it's recommended to fully top off the charge every week or so, by letting the 25A charger do its job for 12 to 24 hours.
These are the best options for good battery health and longevity.
If you don't want to
fork over excessively for a 25A quality charger, and still get all the bells and whistles, there is help.
Now, for all the other valuable information, pls
check out my profile.
Best regards, Peter
