The PV voltages listed are for reference and are not intended to be the only PV voltages supported.
Classic owner’s manual (continued) Figure 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 if this is not the first removal of this cover there is a cable connecting the cover to the electronics. Do not pull hard or fast as damage could occur. To remove the front cover of the Classic in preparation for installation, remove the 4 Phillips head screws with a #2 Phillips screwdriver.
Classic owner’s manual (continued) Figure 2 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 owner’s manual (continued) 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 the 1 inch close nipple into the E Panel as shown in the E-Panel directions. The 1” close nipple, 3 locknuts and 2 plastic bushings are included with each E-Panel. One locknut acts as a spacer.
Classic owner’s manual (continued) Figure 6 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 71 for more details.
Classic owner’s manual (continued) 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. Sealing the Classic does not make the unit water resistant. To seal the Classic install the solid plastic knock out covers into any unused knock outs and snap the upper vent cover onto the Classic as seen in the photo below.
Classic owner’s manual (continued) “Follow-ME” Charging coordination Follow-Me will allow Classics to share charge stages, as well as Battery temperature info and Ground fault coordination. Follow-Me also allows you to program a single Classic for Equalize charging and it will instruct all the others to Equalize as well. You do need to set the Equalize parameters in each Classic. For the Battery Temp sensor you will need one BTS only and it can be on any of the Classics.
Classic owner’s manual (continued) Addressing the Classics You can assign unique addresses to each networked Classic. This is not necessary for Follow Me to work but it is necessary if you want to view multiple Classics from a single MNGP. To address a Classic simply use the MNGP that is plugged into that Classic, or plug the MNGP into that classic and hold the Left arrow button down and tap the up or down button. The normal default address is 10 so going up will take you to 11 and down to 9.

Moving the cursor left or right using the Left and Right arrow keys, selects the next data points to the left or to the right of the present cursor position. The flashing cursor is short and may be hard to detect at first so you may have to look for it. The cursor aligns and centers itself right on the dot itself that is selected.
Classic owner’s manual (continued) Classic Lite Programming The Classic Lite is based on our Classic charge controller. It has all of the same features, Power and versatility minus only the Graphic Display, and arc fault detection. It can be used in all of the same applications. For the advanced features to be accessed and programmed, you will need to use the Local Application software (available at www.midnitesolar.
Classic owner’s manual (continued) Programming There are four separate ways to program a Classic Lite. 1-The programming is done using Dip Switches under the front cover of the MNLP. 2-The Classic Lite can be programmed with an independent MNGP. 3-The Lite can be Networked with a standard Classic and programmed using the standard Classic’s MNGP 4-The Classic Lite can be programmed using the Local App (Through the Ethernet connection) software available at www.midnitesolar.
Classic owner’s manual (continued) Now you will need to use the supplied tool (Toothpick) to place all 15 switches in the correct position. All the information on the switches can be found on the labels on the MNLP as well as in the tables below. Keep in mind if any of the switches are set to Custom the Lite display becomes a LED display only and you will need to use the included PC software or a MNGP to program the Classic.
Classic owner’s manual (continued) Section 1 Switch settings explained Mode: Switches 1 and 2 (Section 1) On Section 1, the first 2 Switches are used to select which Solar Mode will be used. For “Solar” Mode: set switches 1 and 2 to OFF . This is the optimum setting for virtually all solar installations. For “Legacy “ Mode: Set Switch 1 to OFF and Switch 2 to On. Legacy Mode can be used in cases where the Open Circuit Voltage is close to the battery voltage.
Classic owner’s manual (continued) Section 2 Switch settings explained DHCP or Static IP address Switch 1 (Section 2) On Section 2, Switch 1 when on will enable DHCP.
