Midnite Kid Basic Solar Charging Kit What will I need? Talk to your renewable energy supplier who will help you purchase the solar modules, module mounting hardware and batteries appropriate for your needs. Then use the Midnite Solar KID Charging Kit to tie it all together as a safe and reliable system. Solar modules- what to buy The KID is an MPPT "Maximum Power Point Tracking" charge controller. This type of controller optimizes the match between the solar array (PV panels), and the battery bank.
Midnite Kid Basic Solar Charging Kit Planning Ahead: Things to consider when selecting a location for the BIG BABY and KID: Length of wire- The longer the wire the more voltage drop (power loss) you will have. If you need to run a long distance, it is recommended to use a larger size wire for that specific connection. The KID wall mount terminals will hold a maximum wire size of #8, the internal terminals will accept a maximum wire size of #10.

Midnite Kid Basic Solar Charging Kit Open the Big Baby by removing the 2 screws in the front. Remove the bottom nut from each strain relief and insert them, with threads to the inside, through the top and bottom knock out holes. Firmly hand tighten the nuts to secure the strain reliefs to the Big Baby. The Conduit adapter will go in the top of the BigBaby.
Midnite Kid Basic Solar Charging Kit All of your Negative wires will come to this busbar. To install it there are 2 screws in the KIT that will attach the black mounting brackets to the BigBaby. Big Baby Wiring NOTE: Please consult your KID manual or see http://www.midnitesolar.com/pdfs/10-293-1_REVE_KIDManual.pdf for accessories that might need to be wired at this time such as ground wires, load and load wiring, etc.
Midnite Kid Basic Solar Charging Kit The breakers when installed should have the letters right side up and the breaker handles should be in the off position. (HINT) When stripping wire, it is recommended to only strip enough insulation off the wire to fit into your connecter, approximately 3/8" for this breaker and for the negative busbar. Why use Ground Fault Protection? A Ground Fault Protection (GFP) will disconnect the solar array from the power system in the event of a ground fault.
Midnite Kid Basic Solar Charging Kit Wiring the GFP-63 breaker The positive PV wire connects to the bottom (the ++ end) of the MNDC-GFP63 breaker on the left-hand side. From the top of the MNDC-GFP63 breaker on the left-hand side, the wire wraps around to the bottom of the PV Breaker. The wire from the top of the PV breaker goes up to the PV + connecter in the KID. The negative wire connects to the negative bus bar. Followed by the white wire from the MNDC-GFP63.
Midnite Kid Basic Solar Charging Kit Mounting the ground bus bar At this time, you can install the non-insulated grounding bus bar in the mounting hole right next to where the battery wires will come into. You will use the fastening hardware for this. Note that the Green wire from the GFP -63 will go right into it. This also where the ground wire goes that is connected to a ground rod or other approved grounding system.
Midnite Kid Basic Solar Charging Kit Estimate the length of wire needed to go from the Big Baby to the KID terminal block. Cut and install two #10 negative wires of appropriate length to the negative bus bar, then two #10 positive wires to the top of the two breakers (the - - end). Pass all four wires out of the top strain relief. Connect your Earth ground wire to the Ground busbar and run that out the top of the KID with the other four wires.
Midnite Kid Basic Solar Charging Kit Marking your wires is ALWAYS a good idea Wiring the KID Controller To make the final connections to the KID, take the two solar wires coming from the top of the Big Baby and pass them through conduit and connect them to the PV Plus and PV Minus terminals. Pass the two remaining battery wires from the Big Baby through the conduit and connect them to the Battery Plus and Battery Minus terminals. When making the KID connections, polarity matters.
Midnite Kid Basic Solar Charging Kit Do NOT make the final connection to your battery terminals at this time or you will be working with live wires! We recommend installing the MNKID at the highest point in your installation. Since the wiring comes out the bottom of the MNKID, it is easier to run the conduit straight down to the BIG BABY. The mounting bracket for the MNKID has a plastic knock out on the bottom right hand side. It is much easier to remove than the one for the BIG BABY.
Midnite Kid Basic Solar Charging Kit Please see http://www.midnitesolar.com/pdfs/Kid-Manual-1797-REV-E.pdf for Startup procedures and other accessories that might need to be wired at this time such as Ground wires, AUX controls, battery temperature sensors, etc. Once you are sure that your wiring is completed, your polarity is correct, and your settings are correct, you are ready to power everything up: 1. 2. 3. 4.
