The hole cut into the wall must be very accurate. A template is provided at the end of this manual. The casting on the KID is 8.65” (21 9mm) x 4.54” (11 5mm) with a .400 (1 0mm) radii on each corner.
Page 7 2. Surface mount. The Kid can be mounted on a wall using the supplied wall mount adapter. As a minimum you will need to supply ½” strain reliefs to secure the wires to the casting. Regular metal strain reliefs are available at any hardware or electrical store.

This bracket comes standard with Marine versions. There are two metal pieces that come with the Marine Mount Bracket. A collar that mounts to the KID and the Marine mounting bracket base. Mount the KID to the collar using four 8-32 screws and nuts provided. The kit is available in black or white.
Page 12 Threadlocker 222 (Purple) is recommended to prevent the marine mount from ® loosening due to vibration. The Kid should be rotated no more than 1 5º to maintain protection from the rain/drip shield. 1 0-268-1 REV P25 1 2 | Page...
Page 13 Remove the screw on the middle right of the back cover and gently remove the back cover. The connections for PV/Wind input, Load/Clipper and Battery out are available on the terminal block shown below, located inside The Kid on the backside of the circuit board. Observe polarity on all connections.
Page 14 The Kid Charge Controller Instructions Grounding Lug Grounding points are provided inside and on the back of The Kid. This ground is inecessary to satisfy the requirements of UL458 Marine and RV standard. Install the external ground lug as shown below with the hardware supplied.

DC voltage rating of the battery bank with a minimum of 5000 Amp interrupt rating. Fuses incorporated into the KID are not to be used as these NEC required overcurrent devices. The internal KID fuses are for internal KID operation only. MidNite Solar manufactures numerous circuit breaker boxes for this use.
Page 16: Aux Input/Output
The Kid Charge Controller Instructions Aux input/output: This 2 position terminal block is the aux input/output. Presently the KID supports only the MidNite Whizbang Jr battery status monitor to these terminals. The top terminal connects to the single wire coming from the Whizbang Jr.
Page 17 See the power graph at the end of this section. Battery voltage for the KID can be 1 2, 24 or 48 volts, so that means when you jump to a 24V battery bank, the KID can process twice the power than if it were connected to a 1 2V battery.

KID and have it act like a 60 amp controller. This requires that the PV input and battery output be paralleled, You accomplish this outside of the KID in a suitable junction box. See page 21 for stacking set-up. Make sure to use wire and breakers of suitable size for each KID.
Page 19 The Kid Charge Controller Instructions Stacking Jumpers MasterStacking Port Slave Stacking Port USB Connector Jumper settings for stacking: In the upper right corner of the circuit board there are two positions for placing jumpers. If not stacking (only one Kid) or stacking two Kids leave the jumpers off. The jumpers may be placed on one pin to be saved for later use.

Battery plus to battery minus to get your nominal voltage. A 1 2V battery should read between 11 .5 and 1 3.00. By the way if it does read below 1 2V, that is not a good sign Then measure it again at the KID terminals.
Page 21 The Kid Charge Controller Instructions The next set of screens are where you select battery type. Selecting the applicable battery type sets some important parameters that are specific to different battery chemistries. The first choice is Flooded. Use the up arrow to see all the choices. Listed below.
Page 22 AGM etc. batteries. Different manufacturers have different requirements. Differences may be subtle, but the KID is capable of very fine adjustment. There is no reason to guess as to these important settings. When done, hit the right arrow key to go to the Float settings screen.
Page 23 Turn on the PV input breaker so the KID has PV array voltage applied. The KID is not yet turned on, so you will need to turn it on. To turn the KID on, you will need to get to the INPUT Main Menu. Use the right arrow key to go to the INPUT menu and push enter.
Page 24 Rebulk is the Voltage set-point at which the Float stage will terminate and return to Bulk. In Float, the Kid will return to Bulk if a load placed on the battery bank reduces the battery bank voltage below the Rebulk set point for two minutes.
Page 25 The Kid Charge Controller Instructions Load Menu: All loads are connected to the LOAD terminals of the main KID terminal block. Programming the Load Functions determine how and where the load is connected. (Battery vs. Input). Hitting the right arrow key brings up the INPUT menu.

Page 29 The first (left) screen shows: The 9.5a as depicted above represents the PV array output current. BULKMPPT shows the state that the charger is in. BULKMPPT means the KID is going all out to put all available energy into the batteries.
Page 30 Setting up The Kid for use with a Whiz Bang Jr. (Sold separately) State Of Charge: The Kid in conjunction with the Whiz-Bang JR. offer a real battery tate harge meter. There is some set-up before using the WBJr. It is necessary to enter values for Battery bank size in Amp- Hours, battery efficiency, Battery temperature compensation reference, and percentage of change per degree C.

- Plug the other end into an available USB port on the PC. - Go to MAIN Menu on the Kid And scroll to the right to the TECH menu and press Enter. - Press the down arrow key until Firmware Update is selected and press Enter.
Page 32 Eco mode is the default mode. This mode will turn off the Backlight after 5 min of no user input on the keypad. Turning the backlight off helps reduce the idle power of the Kid by 1 /3 of a watt. This mode will also return the menus to the Main Status menu after 5 minutes has elapsed.
Page 33 LEDs as indicators, The top 3 LEDs refer to the Battery Capacity Meter function on the kid that indicates to the user the current battery status at a glance (refer to BCM Section for more info). The FLT LED will come on when the unit goes to Float. It will blink Slowly when the unit goes to Float MPPT.
