My Danfoss motors all use 24vdc.
When I power them off the 12 cell bank the aggregate total amp hour usage for refrigerator and freezer = 116 amperes hours. They are 18 CF units.
When I use a 24 volt power supply AC to DC 2,784 watt hours.
Through the power supply is 3,313 Volt Amp Hours.
But storage vs domestic power is one thing, and
CEF via AC powered battery charging, another.
If only interested in power drawn by the compressor use the topmost figures as a rough estimate, battery charging (CEF) may not be an important factor.
