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 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.
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.
Classic Power Curves 8|Page
Figure 2.1 The graphs above represent the max power output for a given input for each Classic. Using and understanding these power graphs will help maximize 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.
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.
*1 ten foot custom USB cable **Note. These items are optional email customerservice@midnitesolar.com for more information 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 as damage could occur.
Mounting the Classic The following section covers typical mounting arrangements. If you require additional details that are not covered here please contact our technical support team. The Classic is designed to be directly mounted onto the MidNite Solar E-Panel. The Classic can also accommodate other installation methods as well. Mount in an upright position out of direct sunlight when possible.
Classic has four one inch knock outs that are pre cast. The Classic has mounting locations and conduit locations are similar to other brands of charge controllers to facilitate ease of upgrading older technologies. Mounting the Classic directly to the E Panel: *Remove the front cover of the Classic. *Install the mounting bracket on the E Panel and start the upper mounting screw into the bracket leaving it about half way out so you can hang the Classic on this screw.
Install locknut here to act as a spacer. Alternative Mounting To mount the Classic to a plywood surface use 1 1/2‖ wood screws in the top key hole slot hole and the holes in the wiring compartment. Taking care to make sure the Classic is Plumb and Level. Dimensions See page 40 for more details. Sealed or Vented The Classic has the ability to be sealed for protection from salt air or dust. It comes from the factory Vented. If you live in a dusty or salt air environment you may wish to seal the Classic.
plastic knock out covers into any unused knock outs and snap the upper vent cover onto the Classic as seen in the photo below. Note that the Classic will be slightly de-rated (puts out less power) by sealing it. Refer to the specifications page of the owner‘s manual for the ratings in the sealed mode. To obtain the parts necessary to seal the Classic please contact our Technical Support Team. Refer to Figure 1.4 and 1.5 Figure 1.4 Figure 1.

Chassis Grounding In all installations the Classic chassis should be connected to ground. For systems with a battery breaker sized 60 amps and smaller 10 AWG (6 mm2) copper is generally sufficient. For systems with a battery breaker sized 100 amps and smaller 8 AWG (10 mm2) copper is required. For grounding conductor requirements on your specific installation please consult your local electrical code.
DC GFP (Ground Fault Protection) The Classic has internal ground fault protection (GFP) built in. Since 2008 the NEC requires a DC-GFP on all PV systems in the USA. The built in DC-GFP eliminates the need to purchase and install an external DC-GFP. If the internal grounding jumper is installed in a Classic, the battery negative and DC source negative must not be connected to the system grounding conductor anywhere in the system. Grounding of these circuits will defeat the GFP function.
Wiring the Classic WARNING: Shock hazard. Disconnect the batteries and input power before opening the Classic front cover When two or more Classics are paralleled onto one DC Source a blocking diode must be used between each Classic and the input source to isolate each Classic from the other ones. The Classic should be wired by a qualified professional and needs to meet all applicable electrical codes.
Figure 2.
DC Terminal Connector Figure 2.4 The Classic's DC terminal connector is located on the circuit board as shown in. The connector will take up to a #4 AWG. #4 AWG THHN when installed in the Classic and MidNite E-Panel is rated for over 100 amps and is therefore suitable for the highest power available from the Classic 150.
Temperature Current Limit The Classic has a current limit component which interacts with the temperature of the charge controller. If the Classic is exposed to extremely hot ambient conditions the output current will be reduced automatically to keep the charge controller safe, if the orange LED comes on, on the MNGP it means that the Classic is in current limit mode. If you believe the Classic is not hot and the orange LED is on, most likely the current limit set point is too low.
Connecting the Classic to the Clipper Not Yet Available Please email customerservice@midnitesolar for status updates on the Clipper. Maximum and Minimum Wire Size The Classic DC terminal connector will accept wire from #14-#4 AWG Commissioning the Classic The Classic will enter into the setup wizard upon initial power up. If the Classic does not enter into the setup wizard or you want to enter the wizard at any time follow these steps to get into the setup wizard. Press the Main Menu button.

helps determine when the Classic wakes up and when it goes to sleep. This setting tells the Classic when sunrise and sunset are to happen. The Classic will use this information on future features also. To set longitude and latitude coordinates you need to go thought the WIZARD that is the only way to gain access of this feature Configuring Auxiliary Input/Output The Classic includes two auxiliary ports which can be configured to become inputs or outputs.
Aux 1 Vent Fan Lo This mode will turn Aux 1 off above the voltage set point you program. It allows you to run a vent fan for a battery bank based on battery voltage. There is a voltage set point that you set and Aux 1 will turn off when the battery reaches that set point. The voltage has to fall 2 tenths of a volt below the set point for 30 seconds before Aux 1 will turn back on. Vent Fan High This mode will turn Aux 1 on above the voltage set point you program.
Pv V on High This Mode will turn Aux 1 on above a user set voltage based on the input voltage to the Classic ( V High) and turn Aux 1 off when it hits a low voltage set point (V Low). It also allows you to set a delay time in seconds the Classic will wait before turning Aux 1 on after reaching the V High set point. It also allows you to set a hold time in seconds the Classic will wait before turning Aux 1 off after reaching the V Low set point.
Aux 2 Float Low This mode will turn Aux 2 off whenever the Classic is in Float. Aux 2 will stay off until the Classic falls 3 tenths of a volt below the float voltage set point. Float High This mode will turn Aux 2 on whenever the Classic is in Float. Aux 2 will stay on until the Classic falls 3 tenths of a volt below the float voltage set point. Day Light This mode will turn on Aux 2 at sunrise and turn it off at sunset based on the PV input voltage.
Opportunity Hi This mode is PWM based and will PWM Aux 2 when the Classic gets within a certain range of the voltage set points for each charging stage (V High) and stop when it gets to a low set point (V Low). These set points are user adjustable and will allow the Absorb, Float and EQ timers to continue to run. You will adjust these set points to negative numbers and the numbers are an offset from the voltage set point. For example a -.2 would turn Aux 2 on 2 tenths of a volt below your set points.

See page 44 for entire Menu Map. Viewing Other MidNite Products on the Display The Classic is able to view other products or Classics connected to the network. For example: the MidNite Solar Clipper.
Arc Fault The Arc Fault Detector is a unique safety component included in every Classic, because safety is not an option, the engineers at MidNite take action as the 2011 NEC code requires. The Classic is the first charge controller in the world to successfully stop a series arc. The Classic can detect an arc in less than 100mSec.
In order for the Classic to read the new settings you must power cycle the Classic. Do this by turning the DC source (PV, Wind or hydro etc.) breaker off. Then turn off the external battery breaker. Than simply turn the 2 breakers back on starting with the battery breaker. View Faults and Warning's The Classic has some helpful safety features including the GFP (Ground Fault Protection) and AFD (Arc Fault Detector).

Communication Statistics are all Read/Write registers. You may write any value to these registers which will be incremented should the trigger for that counter occur. The most useful type of write may be to periodically reset the counters to zero. These are all lifetime counters and due to the number of MODBUS transactions may overflow to 0.

Dealer Information Screen For dealers‘ convenience the Classic has a display screen that can be modified to publicize the dealers‘ business information. This is helpful because the customer will know who to contact in case they want to report any problems regarding the product. This will also help to promote retailers‘ accessories that are compatible with the Classic. This screen is capable of 20 characters per row and four rows, for a total of 80 modifiable characters.
HyperVOC ™ Origins HyperVOC can be useful in overcoming an industry shortcoming in charging 48 volt battery‘s with standard panels. For example let‘s take a sample system with Solar World 165‘s that have a VOC of 44.1vdc. The industry has limited us to 2 of these panels in series making it hard to charge a 48vdc battery on hot summer days. With the Classic we designed in Hyper VOC to allow you to run 3 of these in series. 3 panels at 44.1vdc will give you a total VOC of 132.3vdc.

Default Battery charge set points The table below describes the default preset voltages for the different nominal battery voltages. This means that if you set the Classic from the QUICK SET Menu (see page 25) to a different battery voltage the Classic will take the default voltage set points. Note. If you manually adjust the absorb float or equalize voltage set point, and then nominal battery voltage is changed to a different nominal voltage, (e.g. from 24v to 12v or to 48v etc.
