Hey Jim, Could you walk me thru the way you calculated your solar panel requirements. I've got a recent Victron charge controller that reports instantaneous amps going into the battery and cumulative watt-hours for the day, but not amp-hours.
How did you determine you were short 3 panels based on knowing that your PV array produces 16 amps (instantaneous?) at noon?

Hi Steve
I'm sure Jim will get back to you. But in the mean time...
Remember volts x amps = watts. So the same can be said: volts x amp hours = watt hours.
If you divide your Victron reported daily watt hours by 12 volts, this equals your daily amp hours. I have a Victron 100/50 and the instant read is interesting, but you can easily see the effect of a cloud going by. So to me the instant read is not that useful.
He wants to generate 132ah during 5 hours of sunshine. He gets 19ah during the noon hour. Presently he generates 19ah*5hr=95ah. And that's optimistic bec 2.5 hrs before noon is not as good as noon, the ah(s) are tapering up to the noon reading. Ditto the second 2.5 hrs, the ah(s) are tapering down from the noon reading. So at 95 he's short 37ah (132-95). Doubling his 3 solar panels will give him (95ah*2=) 190ah. A good deal more than the 132ah he needs. So even on cloudy days, and considering the tapering up and down, he'll probably still get the 132ah per day he wants.
Hope the math helps.
Mike

So Jim in on another forum now, but I'm curious, too. I have AGM batteries, and I think the temp-sensor should be reporting battery temp. So I'm kinda thinking the place to mount the sensor is in the middle of the battery bank. I have 4 batteries, so I'd be mounting mine between the two outer pairs. Not on just a single terminal of one battery.
Can someone weigh it?

You're right, you do want it to measure the temperature at the battery. That reported temperature is used by the charge controller to somehow adjust the power it sends to the battery bank. I think the question is which battery to connect to. That may vary depending on any particular battery bank setup. Personally, I don't think the temperature around the batteries varies enough to really matter. I'd place it as close to the middle as is practical.
Just my 2 cents.

You're replying to a thread from 2019 and the OP hasn't been on the boards for 9 months. But that said, post #3 in this thread has a "shopping list" of what he used, including the boxes with Amazon links.
The other option you could take is going to a local hardware store and browse for solutions, if you're a bit creative and handy.2022 GMC Sierra 3500 AT4, CC, SRW, 6.6L L8T Gas, MYD 6-Speed
