  • Page 7: Scope

    The Classic is designed to regulate DC input from PV, and Approved Hydro and Wind turbines for other DC sources please contact MidNite Solar tech support.. The Classic 150, 200 and 250 are designed to work with 12, 24, 36, 48, 60 and 72 volt battery banks.
  • Page 8 •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 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.

    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 if this is not the first removal of this cover there is a cable connecting the cover to the electronics.

  • Page 13: Mounting The Classic

    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. For your convenience the Classic has four one inch knock outs that are pre cast.

    Classic Stacking Cable Routing and Installation Guidelines The Classic uses a 4 conductor phone cable to communicate with other Classic's or other MidNite products. This cable is a standard 4 conductor phone cable and simply plugs into the jack on the Master Classic labeled slave. Plug the other end into the master jack on the second device (Slave).

    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 mm ) copper is generally sufficient. For systems with a battery breaker sized 100 amps and smaller 8 AWG (10 mm ) copper is required.

  • Page 21: Dc Gfp (Ground Fault Protection)

    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.

  • Page 31: Mode Is Off

    Mode is OFF The Classic is unique, it has multiple charging algorithms for just about any DC input. Because we support such a wide variety of DC inputs we have also added a software “ON” and “OFF” feature. This software “Switch” basical- ly turns the relay off effectively disconnecting the input source so the Classic will not charge the battery.

If you are making your own cable be sure be sure to insert cable end all the way into the phone terminal to get a good contact.

  • Page 43: Arc Fault

    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.

  • Page 44: View Faults And Warning's

    SENSITIVITY: This parameter determines how sensitive the Arc fault detector will be 1 being the most sensitive and 15 the least. This parameter is set to 10 from the factory. If you experience nuisance tripping you can raise the sensitivity one digit at a time. Follow the instructions below to make adjustments or disable Arc fault.

When entering the "LOGS" menu, you will see two items displayed there. The top line is lifetime kW- Hours for the Classic and below that is time spent in float today.
  • Page 46 The HOURLY log menu (actually captured every 5 minutes), works very similar to the DAILY log menu, except that the time stamp above the word TIME is the time, shown in 24 hour format, that the data was captured that day. The category of data captured is of course more suited for minute by minute capture rather than the maximum data statistics captured on a day by day basis in the DAILY log screen.

  • Page 49: Dealer Information Screen

    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.

  • Page 67: Hypervoc

    For example, the Classic 150 has an input voltage rating of 150 operating volts, if the Classic 150 is connected to a 48 volt battery bank, the HyperVOC voltage limit will be: 150V + 48V a total of 198 Volts that the Classic can withstand without breaking. When the Classic input voltage rises above 150 volts it will switch off (stop outputting power).

  • Page 100 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.
