What does that .35 KWH mean to a boat's electric
system, do you know?
?? KWH is thousands of watts per hour. 0.35 Kwh is 350 watts for one hour. If that is the total consumption
of the machine from start to finish of making a loaf of bread then for a 220VAC machine you are looking at 32 amphours from a 12VDC battery/inverter. If the machine is 120VAC then about 29 amphours from a 12VDC battery/inverter.
- - But if that is the machine's power usage per hour, then given a 3 hour heat and mixing/kneading time that is 1050 watts total. The voltage requirement of the machine makes a slight difference.
- - If using a 220VAC machine that is approximately 4.8 amphours of AC power. If using an inverter on 12VDC batteries you are looking at about approximately 96 to 100 amphours out of the batteries.
- - If using 120VAC machine that is 8.75 amp hours of AC power. Again about approximately 90+ amphours of battery
- - So running that type machine strictly off the batteries through an inverter is rather expensive.
- - It is the long hours of running that makes running it off an inverter not very economical. Depending upon the cycle program you input into the machine the run/bake times can vary dramatically and likewise the power drain would vary significantly.
- - Running if off an operating engine
high output alternator
or shore power
or a genset that is also being used for battery charging
, watermaking, and other AC power hogs makes more sense.
