Scope
This Manual provides safety guidelines and installation information for the Classic charge controller. It
does not provide brand specific information about photovoltaic panels, batteries etc. Contact the
manufacturer of other components in the system for relevant technical data.
Introduction
The MidNite Classic charge controller is unique in its ability to be used for a great variety of DC input
sources. The Classic is designed to regulate DC input from PV, Hydro, Wind and other DC sources..
The Classic 150, 200 and 250 are designed to work with 12, 24, 36, 48, 60 and 72 volt battery banks.
The Classic can be installed stand alone or as a multi-unit networked installation.
Standard features of the Classic charge controller include:
*3 input operating voltage ranges 150, 200 and 250 VDC
*Multiple DC input options (example Solar, Wind or Hydro)
*Wizard driven setup interface including voice and help screens
*Graphical display
*Previous 180 days of operational data logged
*Internet ready
This Manual covers Classic 150, Classic 200 and the Classic 250. It covers the installation, wiring and
use of the Classic charge controller.
WARNING Warnings identify conditions or practices that could result in personal injury or loss of life.
CAUTION Cautions identify conditions or practices that could result in damage to the unit or other eq-
ment.
MIDNITE SOLAR CHARGE CONTROLLER INSTALLATION GUIDELINES AND SAFETY
INSTRUCTIONS
This product is intended to be installed as part of a permanently grounded electrical system as shown in the
system configuration sections. The following important restrictions apply unless superseded by local or national
codes:
•The System's DC Negative conductor must not be bonded to earth ground . The Classic does this with its
internal Ground Fault Protection circuitry. The battery negative and ground are not bonded together directly but
are connected together by the Classic’s internal GFP device. All negative conductor connections must be kept
separate from the grounding conductor connections. The equipment ground terminal inside the Classic must be
6 | Page
connected to Earth Ground for the internal DC-GFP to work.
• With the exception of certain telecom applications, the Charge Controller should never be positive grounded.
• The Charge Controller equipment ground is marked with this symbol:
• If damaged or malfunctioning, the Charge Controller should only be disassembled and repaired by a qualified
service center. Please contact your renewable energy dealer/installer for assistance. Incorrect reassembly risks
malfunction, electric shock or fire.
• The Charge Controller is designed for indoor installation or installation inside a weatherproof enclosure. It
must not be exposed to rain and should be installed out of direct sunlight.
For routine, user-approved maintenance:
• Turn off all circuit breakers, including those to the solar modules, batteries and related electrical connections
before performing any maintenance.
Standards and Requirements
All installations must comply with national and local electrical codes; professional installation is recommended.
The NEC in the USA requires a DC ground fault interrupter for all residential PV installations. NEC2011
requires an ARC FAULT detector on all charge controllers and inverters operating above 80VDC. Both of these
devices are built into the Classic.
DC and Battery-Related Installation Requirements:
All DC cables must meet local and national codes.
Shut off all DC breakers before connecting any wiring.
Torque all the Charge Controller’s wire lugs and ground terminals to the specs found on page XX.
Copper wiring must be rated at 75° C or higher.
Keep cables close together (e.g., using a tie-wrap) as much as possible to reduce inductance.
Ensure both cables pass through the same knockout and conduit to allow the inductive currents to cancel.
DC battery over-current protection must be used as part of the installation.
Breakers between the battery and the Classic must meet UL489 standards.
Breakers between the DC source and the Classic must meet UL1077 or UL489 standards.
Design the battery enclosure to prevent accumulation of hydrogen gas at the top of the enclosure. Vent the
battery compartment from the highest point to the outside. A sloped lid can also be used to direct the flow of
hydrogen to the vent opening. Sealed (AGM, Gel etc) batteries do not normally require ventilation. Consult your
battery manufacturer for details.
WARNING: PERSONAL PRECAUTIONS DURING INSTALLATION
WARNING BATTERIES PRESENT RISK OF
ELECTRICAL SHOCK, BURN FROM HIGH SHORTCIRCUIT CURRENT, FIRE OR
EXPLOSION FROM VENTED GASES. FOLLOW PROPER PRECAUTIONS.
• Someone should be within range of your voice to come to your aid if needed.
• Keep plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
• Wear complete eye protection. Avoid touching eyes while working near batteries. Wash your hands with soap
and warm water when done.
7 | Page
• If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters an eye, flood the
eye with running cool water at once for at least 15 minutes and get medical attention immediately following.
• Baking soda neutralizes lead acid battery electrolyte. Keep a supply on hand in the area of the batteries.
• NEVER smoke or allow a spark or flame in vicinity of a battery or generator.
• Be cautious to reduce the risk of dropping a metal tool onto batteries. It could short the batteries or other
electrical parts that can result in fire or explosion.
• Never wear metal items such as rings, bracelets, necklaces, and watches when working with a battery or other
electrical current. A battery can produce a short circuit current high enough to weld a ring or the like to metal,
causing severe burns.
Classic power curves
figure 2.1
figure 2.2
8 | Page
figure 2.3
The graphs above represent the max power output for a given input for each Classic. Using and understanding
these power graphs will help maximizing Classic’s output power and aid in selecting wire and
breaker/disconnects. The built in set up wizard also helps select breakers and wire sizes. Notice that lower
battery voltages and lower PV input voltages result in higher continuous output power. The PV voltages listed
are for reference and are not intended to be the only PV voltages supported. The battery voltages listed show the
most used battery bank configurations. Other voltages are also supported. The Classic battery voltage parameters
are fully user adjustable.
For example: if you are using a Classic 250 and 48v battery bank, the maximum continuous output power based
on 25 degree C ambient is 55 amps when using a PV array that yields a Maximum Power Voltage of 180 volts.
The same set up using a bit higher voltage modules that result in a 200V Maximum Power voltage will result in
only 53 amps. Although 55 to 53 amps is not a significant change, it does give you the idea that all things being
equal, lower voltages are a bit more efficient.
Below are the labels present on the Classic.

Unpacking the Classic
When you receive your Classic you will want to unpack it and make sure everything is there and in
good shape. Refer to Figure 1.1. Included in the Classic package should be:
*Classic charge controller
*Battery temperature sensor
*Snap on upper vent cover
*Knock out covers 4 screened and 4 solid
10 | Page
*User’s manual CD, printed installation instructions
*1 ten foot custom USB cable
If anything is missing or damaged please refer to Page 2 for details on contacting us.
Figure 1.1
Removing and installing the front cover on the Classic
Removing the front art deco cover is required to gain access to the wiring compartment.
Be aware there is a cable connecting the cover to the electronics. Do not pull hard or fast.
Damage will result.
To remove the front cover of the Classic in preparation for installation, remove the 4 Phillips head
screws with a #2 Phillips screwdriver. Lift the front half of the Classic casting off. You will need to
unplug the display cable. It works the same as any 10” long 6 conductor phone cable.
To re-install the front cover of the Classic you will need to plug in the display cable and carefully route
it around the components on the circuit board as you set the cover in place. See Figure 1.2 Do not force
the cover if it does not seat into place easily stop and look for any cables or wires that may be
interfering. With the cover seated in place install the four Phillips screws with a #2 Phillips screwdriver.
