Classic Manual Rev L

Insomnia – When enabled, will keep the Classic from going to Resting. This is intended for hydro
mode only where you may need time to open water valves and do not want to wait for the Classic to
wake up.
LED-MODE – This selection lets you pick the function of the six visible LEDs on a standard Classic.
LMX – LoMax. This enables the Classic to track the input voltage all the way down to battery
voltage. When disabled the Classic will stop tracking the input around 5V above the battery voltage.
When the input voltage is within a couple volts of the battery voltage, the inductors can “sing;” this
is usually not very loud and will do no harm.
Local App – Software to monitor Classic over a Local Network or Internet.
MNGP – Midnite Graphical Interface Panel, included with the standard Classic.
Mode – This menu lets you turn the charging ability of the controller On or Off, as well as lets you
select the DC input source.
Mod Bus – a standard protocol used for communications. We have published our protocol to allow
users to interface with the Classic. See www.midnitesolar.com for our Mod Bus protocol.
My MidNite – Web-based monitoring for the Classic.
NiteLog – When enabled, allows the Classic to log data in the evening when the Classic is Resting.
PV Shading – Indicates the maximum power point voltage is less than half the open circuit voltage.
Pwr Save – Allows you to adjust the time the MNGP backlight stays on.
Resting – The Classic is not charging the battery.
Shade – When enabled the Classic will show PV Shading on the display when the maximum power
point voltage is less than half the open circuit voltage.
T-Comp – Temperature compensation using a temperature sensor to measure the ambient
temperature of the battery bank and will adjust the voltage set points up or down accordingly to
ensure a full battery charge. There are 3 parameters to set: 1) Minimum adjusted voltage; 2)
Maximum adjusted voltage; and 3) Volts per degree C per Cell. Typically this is -5 mV, but please
consult your battery manufacturer.
VBatt– Battery voltage, measured at the battery terminals of the Classic.
Voc – Open Circuit Voltage, unloaded voltage measurement.
Vpv– Input voltage, measured at the input terminals of the Classic.
Web Access – Allows the Classic to send data over the Internet to My MidNite’s server.
