Quote from: Roger & Susan in Home2 –
The energy guide says this refrigerator uses 330 kW per year.  333000/(24*12) = 37.7 watts per hour.  In 24 hrs that would be 904 watts.

I'm nitpicking, but it's kWh  and would be watt-hour.  Watts (and kW) are measure of power. kWh is energy.

Probably about right Roger, my coach has a 5A+ phantom loading. The duty cycling on the refer would be (hopefully) ~30%.

I hesitate to try to charge any battery at more than 20% capacity.

Bulged many batteries long ago.

My guru buddy will only do 4 mk8g8d's and 500 watts of solar to fix residential refer Issues. Or pass the biz.

What kind of "issues" are being addressed in residential refers by doing four 8d's by your guru?

Battery bank size/ solar size and power consumption (whether residential or other) boils down to just this:

Is the goal to be energy neutral (i.e. no need to run generator) and without depleting the batteries below 50% SOC.

OR

How long can you go without running the generator without depleting batteries below 50% SOC.

No right or wrong answers-- certainly cost and weight are variables in this equation.

sounds like a "calculation" o me, not a "problem", which was my point. Plus a one size fits all approach doesn't speak to analytics, just personal preference.

I don't think I have a "problem" with three 8D's and a residential and no solar. But my times sitting still and not boon docking are usually a Nascar weekend.

What wolfe10 said.  Most other brands also have much larger parasitic losses according to him.  We do not.

More batteries can be recharged quicker to lessen the .44 GPH gen fuel use and the gen smell and noise.

We prefer dry camping where possible and dislike the gen noise around the campsite

I think over an average day a 500 watt solar system should recharge four 8d's back to acceptance voltage fairly well.

Some gen run time by the second day?
