Residential fridges

[Pete Masterson]

Nope... AGMs must be charged at a lower voltage to avoid damage. I note that the Link 2000R would float at about 13.5 volts with the wet cell setting, but floats at 12.9 volts with the AGMs. (The charging rate is preprogramed -- you simply (well, it's not _that_ simple) set the kind (wet, AGM, gel cell) and the battery size (amp hour rating) into the controller and it chooses to do whatever it is it does.)

The dual inverters in my coach have 4 breakers that control what they serve. I've not gone to the trouble to figure out what each breaker serves individually.

I can see the advantage of having a smaller, true sine wave (my inverters are modified sine wave, which is less efficient for the refrigerator) dedicated to the refrigerator. 

While parked in Oregon, I checked temperatures in the refrigerator during the day (when the generator was unusable) and it took about 6 hours for the interior to get into the 'danger' zone on the refrigerator thermometer I use.

Hi Pete,
Aren't the charger settings for AGM the same as  Lead/acid.? (not like Gel)
The new 450 LXi has a single smaller inverter for the fridge (1500 true sine wave.) I turn the 2, 3600 watt ones off and turn the fridge down(really up) for night.
