Programming the Midnite Kid MPPT to charge a lithium battery

[@M.Neville]

Always nice to see Ryan explain in videos, so easy to follow and understand. Great job filming!

Glad it was helpful

Thank you! just what I needed. Very easy to follow. Midnight Solar instructions a little difficult to follow for an old man like me. Switching my lead acid battery to lithium on my travel trailer.

just like to say you have one of the best info to for the diy especially for the midnite mppt cause they are a great set up just lacking instructions thanks for the great video

[@aroundthehomesteadwithsuer3497]

Thanks James! If you ever have any specific questions particularly about Midnite products we are always happy to answer them and do a video!

[@zachreyhelmberger894]

Awesome video!! Will look up specs for the 12V 100Ah DJLBERMPW battery.

[@aroundthehomesteadwithsuer3497]

Sounds good, Glad the video was helpful

My go to source for messing with my midnite controllers

Glad it helps

Where do we get a kid that jack o lantern color?

[@aroundthehomesteadwithsuer3497]

Well, it helps when your wife knows the head of the powder coating shop down the road lol, She said she wanted it orange, and they made it metalic orange.

Where can I get a midnite charge controller control board please let me know

[@aroundthehomesteadwithsuer3497]

email support at Midnite [e-mail] they can help you find where to buy one

Im going to have to call midnite support because i never got an option to choose a battery type. It wont let me lower my max voltage either under 30v.

[@aroundthehomesteadwithsuer3497]

Sounds like it was previously set up for maybe 48v, You will want to do a factory restore ad set it up correctly. Turn off the PV and battery power and wait for it to go dark. Now hold the left and right arrows and apply battery power only. Keep holding the arrows for about 5 seconds after the display lights. You should then get the screens asking for battery type and settings etc

@aroundthehomesteadwithsuer3497 I tried factory reset and it worked I guess. It's still won't let me drop the max voltage below 28.9v for float. I'm trying to set up for my power queen battery that shows it 100% at 27v. I believe midnite hasn't ruled in real lithium charging if you can't actually control the voltages. Also I connected my whizbang jr. And it shows my battery at 100% at 26.4 but it should only be at 60 or 70 percent from storage. I'm feeling like agm was the way to go. Yes I'm going by the parameters power queen has suggested for the battery. I'll keep trying to figure it out. I'm calling support today for a full rundown to make sure the kid isn't faulty. Also after auditing my whole system and checking all connections, when I trip my breakers for my pv array the kid still shows incoming voltage at 23.4v but no amps and says resting. My dad has one wired the same way and his never did that. I'm on the stress train lol.

@@enki2gold Something is definitely odd as Float should be allowed to go almost to 0v. As for the WBjr did you program the capacity and the efficiency and has it gone through a complete charge cycle? Definitely call Midnite, I would ask for Shawn or Jim Parish

I purchased a Kid and an enjoybot 200 ah lithium I have been trying to get the specs you say I need...especially the absorb time. Here is what they told me....The absorption time is actually the charging time, which depends on the charger or charging settings you use. For example, if your battery is 200Ah and your charging current is 40A, then the absorption time is equal to 200Ah divided by 40A, which is 5 hours. The absorption time should be set to the maximum value as much as possible, so it can also be set to 6 hours. If your charging current is 20A, then the absorption time is 200Ah divided by 20A, which is 10 hours. The absorption time should be set to the maximum value as much as possible, so it can also be set to 11 hours. Does that sound right to you? Thanks for your video and help.

[@aroundthehomesteadwithsuer3497]

Sounds a little odd but it could be they are using Absorb as a simple voltage to indicate full. I am assuming they are passively balanced this the long Absorb Time.
