Stupid battery and solar questions
I figure I am going to have a lot of them, so I better put all in one thread :B. My situation: - I mainly want solar for running residential freezer and fridge, maybe also for charging my shave ...

my kill-a-watt blew a fuse. the tiny one
i need to fix it
and also while watts is the most common measure used around here
AC power is measured in VA 'volt amps', when comparing ac to DC resistive loads its so close as to be interchangeable, but with inductive loads like compressor motors , it will be off
the 69 watts is closer to the truth than 120w,
then add 10% inverter conversion loss
so i think you can safely calculate loads and run time using 75w for that freezer
what would really tell the tale is measuring the DC amps into the inverter, while running the freezer
for that you need either a clamp on DC amp meter or better yet
a DC power watt meter like the Turnigy or one of its Chinese clones
and the turnigy was a clone of the famous 'watts up'
meter used by RC model enthusiast
