PV Voltage and Charging

[dgd]

Think that that AC = A/C=Air Conditioning (probably).

Alternating Current IS always mandatory!

Phew!  That's a relief, I was thinking my DC battery bank would have to be replaced with an AC bank
Thankfully I have plenty of air so conditioning it isnot an issue. Although I'm not sure how to condition the air before it hits my turbine blades. But it's an AC turbine too so that may be ok if it becomes mandatory...

Update and question:

It was cloudy all day yesterday so I thought I'd start from scratch. I shut down Whizbang and via my 65 amp inverter/charger, I ran a 3 hour EQ at higher 31v, then a charge/float all night at standard 27.6v. My SG is now up to 1277, which is higher than I've ever seen. A great starting point.

Question: Even without the Whizbang data the Classic can determine peak SOC? I say this because Classic is no longer charging batteries (346W on a 1700w day (sunny, not so hot)), even though it's set, and active, in absorb mode. That seems pretty cool, would someone explain?

I'll now turn Whizbang back on which should exit Classic from absorb mode and set tomorrow up for EA observations.

Edit:  With an obviously full battery EA has been sitting between 4-5 for almost 2 hours. 690ah*1% = 6.90 but it looks like an EA of 5 should work here.

Edit*2:  After re-setting EA to 5 and rebooting, Classic jumped into float mode almost immediately.  Leaving absorb time at 8hrs because I don't see any downside in doing so and, with Air Conditioner  soon running all day I'll not hit float mode again until late October (eat it, northerners  )

What do you mean you shut down the Whizbang ?  It is just an amp monitor . 
I guess I don't understand what you are doing .
Your video link says it is not there any longer .

I turned it off so EA would not interfere. It's back on now.

The whizbang being on or off will not interfere with anything. It just monitors the amps going in and out of the battery .
The way to turn ending amps on and off is to set it to zero and uncheck the box that say " Use WBjr for ending amps" .

But maybe that is what you mean . I am not sure if you mean  you go to the Config  menu for  AUX 2 and disable it there ?

I realize that but didn't want to take any chances so I shut it down at AUX2. Anyway, I was able to determine proper EA which is what I sought to do.

Now to see if current settings return SG to peak level again.
