Beta KIDs

thats about a 15% load, Was it a DC load or AC , how long did you have it going. 
(sorry keyboard malfunctioning no question or other marks...)

Westbranch thanks for the reply.  I had a PSW inverter connected to the batteries and  750 watt light connected to the inverter. i tried to up load a picture of the display but for some reason it did not work. i had the load on for  8-10 minutes the batteries were down to 12.6 volts.

I don't have a Kid, but most controllers, once they reach float will not start a bulk charge again on the same day unless the voltage sinks to below the ReBulk Voltage setting.

Maybe the Kid is the same way. Most of my experience is with PWM CC which do not have very many electronics. I just looked at the Kid display and it went into Float OK after the load was removed. So maybe everything is OK.

At 12.6V you still have essentially a battery that is still at 95% +- charged.

see chart about 3.4 of the way down...

Hi Kent3,

It is normal for many MPPT CCs to remain in Float Mppt  when there is a load that exceeds the PV input power capability,  UNTIL the battery voltage descends to a ReBulk Voltage setting.

Regarding one of your earlier posts,  it is surprising to me that with ZERO PV input power that the KID would remain in Float MPPT,  as that should mean that the "Converter" is running,  but producing no power.  There could be some reasonable delay in the KID deciding that the Converter should be shut off,  and the CC going to Rest,  or similar state.

And Kent,  what is the nature of the Input to the KID?   What is your battery capacity?  Just curious.

[ And WB,  that Table in the link is for RESTED batteries,  FWIW ].

Currently I have 3- 150 watt panels in parallel (soon to be in series for 24 volt battery bank) also 1 more 150 watt to be installed when weather is warmer.

Currently using 4 - 12 volt batteries in parallel.

OK Kent,

Sounds great,  glad that you will be moving up to a 24 V system.  Have Fun,   Vic

Hi Vic, that was my point, (should have added more info) that with a 15% load on his battery and reading 12.6V, it is in reality fully charged, at least Grtr than 95%.
When he took the load off it probably went up to +- 13V.

[Vic]

OK WB,  well,  was trying to understand something else that you mentioned -- the 15% reference ...  could not understand,  15% of what (?) ...  went back to look at all of Kent3's other posts,  but still  could not figger it out.

BUT,  anyway,  perhaps the batteries are COLD,  or HOT,  or not ...  and if AGMs  the noted voltage vs SOC COULD be a bit difference ... and so on ...  difficult to guess.

Thanks,        Vic

Hi Vic, I used his system description of 440 Ah and applying an approx load of 65A gives about a 15% instantaneous load, so for a load test that is fairly light but good enough to see what your battery condition is... his only dipped to 12.6V. = healthy battery to me.  It was a test of that type that let me know my old AGMs were dying fast as I saw a crack of the whip or Coup de fouet rebound effect after the test of +-10% load.  YA its a crap shoot trying to sift through this stuff a times

OK WB,

That makes sense,  just did not see ANY signature line at the time of the post above ...   must be blind.

Sometimes,  if someone adds a Sig while another user is logged onto a site,  that Sig will not appear until that other user logs off and back on.

Otherwise,  am just BLIND.  Thanks,    Vic

No worries mate...

Midnite/Mario,

I have a new old issue with my kid. I didnt mention it before because it was around a firmware update and I was willing to wait to see if it would solve it. I did initially but the issue is back in full force. FW for kid is1722. What takes place is the the controller goes into a screen lock where the screen is light and blank after a day of charging and it does not go back to regular operation until a power cycle even when the it get solar input the following day.

Cheers...

Damini, What is the setting for the LCD power mode?

main menu-> MISC-> LCD-> what is the setting there?

Mario

[dapdan]

Mario,

The lcd was set to eco. I set it to normal to see what it would do. I had to do power cycle again to get the controller to respond as it was hung on the blue screen.

Cheers...
