you know morning YouTube so we're out in the solar garden shed and I've got the tracer 2210
a and charge controller there and I've had this installed about two and a half years in the shed
it's been working just fine everything's running normally reason we're out here is I wanted to
answer another viewer question regarding using this Mt 50 remote display so I've got this Mt 50
remote display plugged into the charge controller and I'm using this to charge the two batteries I
have in here and just as a quick summary up on the roof of the shed I've got a pair of 15 watt
amorphous panels and then I have a pair of 60 watt polycrystalline panels that are in series
and then those two are in parallel so you can see I'm getting like 3738 volts on the solar
panels charging the batteries at fourteen point one volts so I've had several viewers asked how
do you change the battery charging parameters using this remote display I did a video a couple
years ago where I showed changing the parameters using the solar station monitor program on a PC
and I did that for my 4s lithium battery bank 16 volts today I'll show you how to do that on this
controller without plugging a PC in it's a little more involved and I'll show you what the problem
is here and then we can look at how to fix it so if I click on the Escape key I go into the menu
mode so most of the charging parameters are in this number 4 control parameters and you hit OK
to go in there so I have the gel battery tight specified although I'm running a GM or sealed
batteries and the reason I did that is because the gel battery type doesn't have any equalization
charge so I've got one of these 12 and power power sonic batteries in my backpack sprayer
right there so then up here in my jumpstart pack I've got a 26 amp hour AGM battery in there and
that charges through the lighter plug okay so let me show you the problem here so I we're coming
at this and I have that battery type and I can go through some of my charging parameters here
I've got the voltages charge a limit over voltage and these are the two main things that you might
want to change your boost charge voltage and your float charge voltage and there's also different
disconnect and reconnect voltages and here's the equalization time so that one's zero minutes boost
charge is set up for two hours hundred twenty minutes so if I wanted to change this I would
just hit OK it's going to prompt for a password I mentioned that in the previous video you can find
a link up there so I just hit OK I don't have a password loaded and there I get the prompt
I can change battery type I can change amp hours and I can click OK and save that change and then
I can come down here so let's say I want to go down here and I want to change my boost charge
voltage because I was looking at the power Sonic datasheet and they give some charging voltages
over here and they said the boost charge should be 14 4 to 14-7 so I'm a little bit low the float
voltage is right they said thirteen point five to thirteen point eight but I would like to raise
that boost voltage so let's go there I'll hit okay I can't change that voltage what do I do
well what you have to do is come around here back to the Stark you have to come to this screen this
is the only thing you can change and what you want to do is you hit okay and I want to change
this to user so I want to have a user-specified battery type by go okay and I save that 200 is
the default so there we go we'll save that page and then I want to come down to the next page
that's okay you want to keep this rated voltage I keep it on auto and that's the default temperature
compensation which i think is okay so what you need to do is go through all of the settings or
the battery type that is closest to what you want and write down all the settings for that battery
tight so I did this in a text file I'll put a link to this text file up on my Google Drive
page and put that link in the video description and so I've got all these voltages and then I
marked the ones that I want to change so I might want to change this 14 to two maybe fourteen five
pick the middle of that range and then likewise I might drop the float charge voltage a little bit
so we'll just go down the screens here I've got the over voltage 16 the charge limit is 15 over
volt is 15 equalized voltage I'm just going to set this to the same as my boost charge voltage
later I'm going to set the equalized time to zero if there's no equalized time and the voltage is
the same as the boost charge there's basically no equalization going on and then here we have boost
charge voltage I wanted to run this up a little bit here so let's go over and I want to go up to
fourteen point five and I want to run the float maybe down to thirteen point seven I want to try
to get it in the range of what annular recommends there's my boost charge float charge and then
let's see I think all these thirteen to twelve point six that's okay those are okay I think those
are okay and then here is where I have to change the equalization time I'll leave the boost time
on a hundred twenty minutes so that's two hours basically says charge at the higher voltage for
two hours in the morning and then switch over to float charge well save so we've got zero
minutes equalize two hours boost and then we're back there and now I have a custom user-defined
battery type so I've still got user 38 amp hours and I've set all my parameters so that's the way
you can change parameters the only one you can change is the user mode now on my older charge
controller I've got the MT five remote display and it only has the three basic battery types it's got
flooded sealed and gel and you can't change any of those parameters the MT 50 controllers have that
user-defined battery type and with user-defined you can change every single parameter but yeah
there we go it's driving the battery voltage up so I think that's a success anyway that's how you
change battery voltages it's a little bit tedious on this controller as compared to the solar
station monitor app because area you have a mouse and a keyboard and you can cut and paste and the
other advantage on the solar station monitoring program is you see all the parameters at once
here you can only see two things at a time the boost voltage float voltage and you change one
digit at a time it's a little bit more tedious but it is doable even if you just want to change
one voltage you've got to do all the voltages luckily there's really only maybe three or
four things in there you've got your boost voltage your float voltage your equalized
voltage boost time and equalized times hope that helps clear up the mystery of how you
change the battery charging parameters on one of these MT 50 remote displays so yeah
if you have any other questions post up in the comment section below and I'll put some of the
other MT 50 display videos over here on the left side and as always thanks for watching
