I cannot find an
uninstaller for the
Midnite firmware
updater?
*Go to the C directory and find the folder labeled midnitesolar and open it. In
here you will find an uninstaller, simply double left click it to run it. After it is
complete you can delete the midnitesolar folder to completely remove any files
left behind
What is the
PASSWORD for the
Classic?
*All Classics use 142 for the password
I hear a singing sound
coming from my
Classic, Sort of a high
pitched whine that varies
*This is the inductors “Singing” when the Input voltage is really low. This is
normal and is no cause for concern, however if it bothers you then you can
disable it by going to the main menu and entering into tweaks. Look for
LoMax and set it to off and press enter.
Note: If the PV array is real low voltage and its max power point is close to the
battery voltage disabling LoMax will cause a slight loss in power as the Classic
will not be able to track all the way to the battery voltage looking for the
MPPT voltage
I have a classic that
came with a grey
“Magnum” Battery temp
sensor can I replace it
with a Midnite blue one?
*No the Magnum sensor was a different resistance value so those classics
where modified to use those sensors. Call customer service if you need help
with a new sensor
How can I verify that all
my fans work on My
Classic?
*If you unplug the battery temp sensor and use a flat bladed screw driver to
short out all 6 pins inside the jack (Carefully so as not to bend the pins) the
fans should all start spinning
How do I find the
“Wizard”?
*You won’t, we removed the wizard as it asked a lot of questions that did
nothing and was confusing, We replaced it with the Quick Start that comes up
when you first power the classic or do a factor restore
My fans run all the time
no matter what the
Classic is doing
*Check to make sure you did not pinch the Fan wire at the top in the casting
I remotely mounted my
MNGP (display) and
now it won’t power on
or it blinks but won’t
power up
*Check that you made the cable exactly the same as the blue one. Note that Pin
one on one end becomes Pin 6 at the other end (Mirror image)
*Try a heavier cable, We have found that off the shelf phone cables are good
for about 25ft max before the voltage drop is to great. We have found that
cable like Cat3 or Cat5E can go about 100ft no problem.
How many amps can my
Classic handle on the
input side? OR Can I put
too much PV on my
Classic?
*The Classic regulates very well so within reason there is no limit on the input
amps or PV wattage. We recommend you not exceed 150% of the capacity.
The Classic, just like a grid tie inverter, can be over driven on the pv side it
simply produces the max amount it is rated for.
My Classic is not
making the same amount
of wattage as I have for
Solar Panels?
*First it should be noted a solar panel is rated in a lab so in the real world we
typically see about 80% of what it is labeled (So a 100 watt panel becomes an
80 watt panel)
*Does the Classic say Absorb, Float or EQ? If so that means the battery is
nearly full and the Classic is throttling back to prevent over charging the
battery.
