Refrigerator draw on LP mode
I'm evaluating my total amp draw in order to properly size a new solar system with lifepo4 batteries and all that entails. My Fridge is a Norcold N821 2-way. The decal inside says it draws .8 amp...

Thanks for your post. I do appreciate what you do. I am a professional paid engineer. (and a **** good one at that) I deal with reality everyday. When I say/suggest my solar panels generate 140 watts, I'm not talking about the manufacturers published wattage, I'm talking about what they actually do, . . . sitting here, right now. I keep track. Currently, I have 3-240 watt Kyocera panels flat mounted on the roof, an MPPT controller and a 1000 watt PSW inverter. I'm not giving away all the details of what I do to make it work. Hire me if you want to know.

Hi Chum lee,
I'd love to have hired you in 2005. But....unless you have a Tardis we could use I guess that won't be happening.
Using the 'usual' 5 hour number the solar harvest for the system is about 3600 watt-hours. It may be that your duty cycle on the fridge is lower than mine.
Iirc the Kyocera are a pretty high voltage panel. I suspect that extends the number of harvest hours to a number greater than the 5 hour "guesstimate".
Thanks for your reply.
