Air conditioning on solar
So today I put together the three solar systems on the 8-D, hooked up the PowerJack inverter and then the 5000 BTU air conditioner. The Air conditioner is a Frigidaire unit that uses 446w/ 3.9a @120v....

Today it was 78 f out and I wanted to test the new panel vs the old and play with the air conditioner again.
Using the 245w Bosch mono and the 250w Navajo poly with a pair of Eco-w's on the combined 345 Ah bank I was able to run the window shaker for four hours.
The draw was higher than before once it got the pressure up but no higher than it's rating. I kept it in the sun to keep the compressor on.
Watts
Volt amps
The inverter was pulling 35a and under meaning the two panels tracking was almost keeping up. Once the voltage dropped a bit the controllers cranked it up to 200w + and I saw the occasion 17.75a each on the controllers.
Like I said the panels were almost enough and the bank was ever so slightly lossing the battle. After four hours the voltage under load did get below 12v after sitting just above 12v for a hour.
If I can do this for the limited times we need it with three panels flat, I will be thrilled. We don't need the trailer to be a ice box, just below 80f is nice.
Now I have to find out where to send the Power verter because it's as squirrely as the last one.
