Kid with Whiz Bang - how do I know current output

[CharlieBecker]

I don't see any status screens that shows how many amps are crossing over the shunt, either going into the batteries or coming out.  I must be missing something because otherwise what's the use of the Whiz Bang!

I'd like to see instantaneous as well as maybe a daily/weekly profile of my power in vs out.

Thanks!

Hi CB,

Did you set it up in the Aux menu?
What happens when you press the right arrow?

The WBjr besides displaying amps can be used for end-amps when charging

Yes as Doug said - maybe you did not set the Whizbang up in the menu's.

But just so you know, the Kid does not do any data logging so no histories will be available. Only what is going on in the present time.

Thanks Doug and ClassicCrazy, but I don't even see what's coming in/out.

Yes, it is set up in Aux menu, I also have EndAmps set for WBJr (Tech/Advanced menu) and 0.1amps (Battery menu).

The only 4 screens I have in status are:

3.4A BulkMPPT
127V Solar 43w

Input    Battery
73.8v      12.7v

0.1a  SOC  100%
330Ah Remaining

Load: Manual
0.0 Off

KWhr    KID   Ahr
0.0                2.0

I just did a factory reset which is why KWhr is 0.0.  I want to see what power is CURRENTLY coming in/out of battery.

Are there any plans for logging with a future firmware that you know of?

Thanks!

I think the first one in your list is the amps coming in from the panel .
The one next to the SOC would be the System amps or what is going into the batteries.  Though in your case I would think it being in Bulk most everything would be going into the batteries unless you had a lot of loads on at the same time then it would not show up in system amps.
If you turn your PV off and then turn a load on the system amps should show negative number - if not something with your Whizbang must not be wired or configured properly .

Page 30 of the owners manual - though I am not sure if any of the recent firmware updates changed these.
I am not by my Kid now so can not look at mine and see what it looks like.
What version of the firmware do you have ? Make sure you have the most recent one.

I believe the Kid owners manual is in process of getting updated and rewritten .

The screen Above is the WBJR status screen.

Is your battery change % set? (Usually 1%). I'm a little confused as to why your batts are at 100% SOC while the Kid is in BulkMPPT. Also, check your batt efficiency setting (generally 94%). If not, that may help explain it. Hope this helps!

I noticed the % change is lost on a kid power cycle and has to be reprogrammed back in (FW 1761).  All other WBJR settings remain.

Go back through all the settings again.

If the OP has just reset the KID, which I think I saw mentioned, then the SOC will say 100% until a full cycle is completed.  The KID has no way of knowing what SOC is at that point until it has worked on the battery.

Mario chimed in and mentioned the SOC screen is the WBjr screen.  I will try to add a little more color.  The amps on this screen are the amps that are going to the battery after any live loads have been met.  If your load is greater than the amps coming in on the first screen (status BulkMPPT) then you have more load than PV input and the amps on the SOC screen will show negative.

For example, I run about 2.2A of load at 12v,  24x7.  I pull this load direct off the battery through the shunt and it is picked up by the WBjr.  Right now, my SOC shows 91% and the amps on the SOC/WBjr screen is showing about -2.1a.  It is 2.1 because the battery voltage is closer to 13 after a good day of charging.  During the day, if I had 25A made available by the KID from the panels, the SOC screen would show 22.9a and the first status screen would show 25A BulkMPPT or similar.

Hope this helps.  It looks like you may be set up right and just needed some help with what you were looking at?
