good afternoon YouTube so this is the mt50 remote display that's on
my EP ever 20 amp Tracer charge controller
and I've had a number of requests from viewers to do an overview of how I have this set up I've
made a series of videos over the last few years showing particular details but people want to
see an all-in-one summary so right here you can see I've got the solar coming in there's not much
power coming in the sun's just going over the house and as far as solar panels I have two 60
watt 12 volt panels in series and two 15 watt 12 volt panels in series so that's about 150
watts total open circuit voltage will get up to 43 volts I think and then about three and a half
amps short circuit current on there and I've got my DC load here and I can turn on a light
the load will go up to about half an amp and the OK button can be used to turn that load on and off
so there I've turned the load off and it goes to zero amps I can turn it back on and it jumps
up to half an amp this system has two batteries I have my Harbor Freight jump start battery which is
26 amp hours AGM sealed lead acid battery so my Harbor Freight backpack sprayer is also plugged
in and has a 12 amp hour sealed lead acid battery and if we go here if you hit the Escape key you
come into the menu I'll just step down here to the device info sometimes people get confused
by this screen this is all read only and it just tells you what this charge controller is rated at
so it's rated for up to 24 volt battery up to 20 amp charge current and up to 20 amp on the
DC load output now I'm running 12 volt battery but it still says 24 so that's where people get
confused sometimes it's like how do I change that to 12 well it auto detects the voltage and then
we can come down here to number four is where the parameters are so I have this set up with
the user battery type and that's important because the user battery type is the only setting that you
can change the parameters on and then here's my battery amp hours like I said I've got a 26 amp
hour battery and it's in parallel with a 12 amp hour battery when you have batteries in parallel
you add the amp hours when you have batteries in series you add the voltage I'll talk about the
user setting a little later here so if we go down here here's the temperature coefficient I never
changed that and then you can see it's picked up the 12 volt battery and then here what I've done
for my user battery setup is I took the seal old lead acid battery settings and I modified them
slightly I think I left the over voltage the same but I set the charge limit to 14.7 the power Sonic
data sheet lists 14.4 to 14.7 and then over here I left these basically unchanged but I'm not using
those per se especially the equalization charge so I'll show you that in a little bit here and
then here's the Boost charge so I think I dropped that from 14 7 to 14 6 and then the float charge
the power Sonic data sheet listed 13.5 to 13.8 so I picked 13.7 just a little under the maximum
and then these are the reconnect voltages I left these unchanged you can change them if you want
and then the low voltage warning and the disconnect 11.1 or 10.6 volts you can change
those if you want and then what I did here on equalize time this is one I changed because I
don't want to equalize these batteries I just set that to zero minutes so there's no Equalization
so if you do that it doesn't matter what you set the equalize voltage to because it'll never run
and then I maxed out the Boost time up to 120 minutes and then you're back to the beginning
so anyway let's go back up here that was the control parameters uh load set I just have
it set to I believe just manual control so that way the OK button turns it on and off so anyway
there's that device parameters that's just where your serial number is I set the ID on this one to
two I've got two of these displays I've got one and then this is zero zero two so if I ever were
to connect these on a network this would show up as controller number zero zero two and the
other one would show up as zero zero one you can change the backlight up to 120 seconds and then
you can also set the time and date there so that's where you do that I have a video on that and then
there's where you change the device password and like I said if you're going to change it
you better remember it and write it down multiple places and if you change the password and then you
forget what it is this unit is it's not brick but you can't change anything ever again you're stuck
with the settings so yeah you got to be careful with that device password but if you're going to
change it you better remember what you changed it to and then you can look at your failure that's an
error log I don't have anything in there nothing there and then meter parameters I think that's
just the software version and whatnot and okay and you're back there so anyway that's all the
settings in there like I said I just took the sealed lead acid settings and then copied those
into the user setting and then I change the Boost and Float voltages basically and then
turned off the equalization charge so anyway that's all the settings in there so hopefully
this video helps you understand all the various parameters in there see it all at once so yeah
that's basically an overview of how I have the mt50 display and the charge controller set up
so this should be very applicable to most of the EP ever BN series charge controllers or any of
them that have the user battery mode so you need the user battery mode to be able to change things
if you're using sealed flooded or gel all those settings are basically read only yeah hopefully
that helps go through all the settings all in one video so I'll put card links to all the detailed
videos where I showed the particular settings that I did a little more detail if you want to
see those anyway if you have any other questions about that post up in the comments section
below give the video a thumbs up if you found it helpful and as always thanks for watching foreign
