IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS - THESE INSTRUCTIONS CONTAIN IMPORTANT SAFETY AN OPERATING INSTRUCTIONS FOR
THE KI CHARGE CONTROLLER MO EL NUMBERS MNKI -HWB, AN MNKI -HWW.
If you do not fully understand any of the concepts, terminology, or hazards outlined in these instructions, please refer installation to a qualified dealer, electrician or
installer. These instructions are not meant to be a complete explanation of a renewable energy system. All installations must comply with national and local electrical
codes. Professional installation is recommended.
ENERAL PRECAUTIONS :
WORKING WITH OR IN THE VICINITY OF A LEA ACI BATTERY, SEALE OR VENTE IS ANGEROUS. VENTE
BATTERIES GENERATE EXPLOSIVE GASES URING NORMAL OPERATION. FOR THIS REASON, IT IS VERY
IMPORTANT THAT BEFORE SERVICING EQUIPMENT IN THE VICINITY OF LEA -ACI BATTERIES YOU REVIEW AN
FOLLOW THESE INSTRUCTIONS CAREFULLY.
If service or repair should become necessary, contact MidNite Solar Inc. Improper servicing may result in a risk of shock, fire or explosion. To reduce
these risks, disconnect all wiring before attempting any maintenance or cleaning. Turning off the inverter will not reduce these risks. Solar modules
produce power when exposed to light. When it is not possible to disconnect the power coming from the Photovoltaics by an external means such as a
combiner, cover the modules with an opaque material before servicing any connected equipment.
o Not expose to rain or snow. NEVER attempt to charge a frozen battery. o not smoke around batteries.
When it is necessary to remove a battery, make sure that the battery bank disconnect breaker is in the off position and that the PV breakers, grid
breakers and any other sources of power to the inverter are in the off position. Then remove the negative terminal from the battery first .
To reduce risk of battery explosion follow these instructions and those published by the battery manufacturer as well as the manufacturer of any
additional equipment used in the vicinity of the batteries.
Avoid producing sparks in the vicinity of the batteries when using vented batteries. Provide ventilation to clear the area of explosive gases. Sealed AGM
and Gel batteries do not under normal conditions create explosive gases. Refer to the battery manufacturer's documentation. Be especially cautious
when using metal tools. ropping a metal tool onto batteries can short circuit them. The resulting spark can lead to personal injury or damage to the
equipment. Provide ventilation to outdoors from the battery compartment when installing vented batteries such as golf cart T-1 05 batteries. The addition
of a spill tray is also a good idea.
Clean all battery terminals. Very high currents are drawn from the batteries; even a small amount of electrical resistance can result in overheating, poor
performance, premature failure or even fire.
Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes. Wear complete eye and clothing protection. Always
avoid touching eyes while working near batteries. If battery acid or battery terminal corrosion contacts skin or clothing, wash immediately with soap and
water. If acid enters the eyes, immediately flood with cool running water for at least 1 5 minutes and get medical attention immediately. Baking soda
neutralizes battery acid electrolyte. Keep a supply near the batteries
o not work alone. Someone should be in the range of your voice or close enough to come to your aid when you work with or near electrical equipment.
Remove rings, bracelets, necklaces, watches etc. when working with batteries, photovoltaic modules or other electrical equipment. Power from an
illuminated photovoltaic array makes a very effective arc welder with dire consequences if one of the welded pieces is on your person.
To reduce the risk of injury, connect only deep cycle lead acid type rechargeable batteries. Other types of batteries may leak or burst, causing personal
injury or damage.
Wiring methods used shall be in accordance with the Canadian Electrical Code, Part I.
Wiring must be done in accordance with the National Electrical Code Article 690 ANSI/NFPA 70. Use Class 1 wiring methods for field wiring connections
to terminals of a Class 2 circuit. Use only 1 4-1 0 gauge AWM wire. Select the wire gauge used based on the protection provided by the circuit
breakers/fuses. Overcurrent protection must be installed as part of the system installation. Refer to the wiring diagrams provided in
this manual for breaker/fuse/GF I sizes and model numbers.
WARNIN : This unit is not provided with a GF I device. This charge controller must be used with an external GF I device as required by the Article
690 of the National Electrical Code for the installation location.
Use of attachments or accessories not approved by MidNite Solar could result in damage or injury.
Before making any connections verify that the circuit breakers are in the off position including the inverter breaker. ouble check all wiring before
applying power.
While every attempt is made to provide accurate documentation, the accuracy of this manual is not guaranteed and may be
updated at any time without notice. Installer assumes all responsibility.

The KID Wind/Hydro Charge Controller Instructions
Mounting The KID:
There are three methods of mounting available for The KI :
1. In wall mounting.
This is very useful for RV’s, some boats and cabins or just about anywhere you want a built in look.
You will need to ensure that the wall is not so thick as to obstruct the wiring that enters through the
bottom surface of The KI . The conduit wire holes in the bottom of the casting are 0.28” (7mm)
away from the back mounting flange. So if your wall is more than 0.25” (6.35mm) thick, this may
interfere with accessing the wiring behind the wall. The conduit nut or adapter also takes away from
this narrow wall allowance. You may be able to remove some material from the back surface of the
wall to increase clearance.
Mounting holes are designed for #1 0 (5mm) screws.
The hole cut into the wall must be very accurate. A template is provided at the end of this manual.
The back cover of The KI may also be used as a template.
The casting on The KI is 8.65” (21 9mm) x 4.54” (11 5mm) with a .400 (1 0mm) radii on each corner.
Mounting holes are designed for a #1 0 (5mm) screw. The center to center dimensions are 8.763”
(222mm) x 4.5” (11 4mm) The KI has a depth of 1 .45” (37mm) from the mounting flange to the
back surface.
The KI mounted in the wall
Important! A minimum of 2" (50.8 mm) free space is required
behind The KI after mounting to prevent overheating.
IMPORTANT!
o not mount in a zero clearance
compartment. Overheating may
result. 3" clearance in front of fins is
required. The KI produces heat in
normal operation. Free flowing
ventilation around The KI is
required to prevent overheating and
shutdown. This is especially true in
hot environments.
See page 1 3 for wiring
instructions.

The KID Wind/Hydro Charge Controller Instructions
11 | Page 1 0-268-2 REV -
2. Surface mount.
The Wind KI comes pre-installed into the wall mount bracket. These instructions apply to KI s that
are field installed into the wall mount bracket. The KI 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. Metal Romex
strain reliefs are designed to clamp down on Romex shielded cable. You will most likely be using
individual 8 AWG conductors and therefore the outer sheath to protect the conductors will not be
there. Be aware that excessive clamping pressure from the strain relief will bite through the wire
insulation and short the conductors to the case. Not only can this cause fires, it is very hard to
troubleshoot.
Make the wire connections to the terminal block inside The KI , replace the back plate and then
assemble The KI to the wall mount adapter. Use the #1 0 x ¾” Plastite screws provided to secure
The KI to the wall mount adapter.
Secure the plastic wall mount adapter to the wall
using appropriate screws (not provided). Make
sure the screws are adequate for the weight of
The KI . The wall mount adapter is intended to
use #1 0 (5mm) screws.
RI HT: The KI wall/surface mounted.
Locate and twist out the
knockouts in the bottom
section of the wall mount
adapter.
IMPORTANT!
o not mount in a zero clearance
compartment. Overheating may result. 3"
clearance in front of fins is required. The KI
produces heat in normal operation. Free
flowing ventilation around The KI is required
to prevent overheating and shutdown. This is
especially true in hot environments. See wiring instructions starting on page 1 6

Optional rain Shield .
Required for approved marine applications.
The KI shown with the optional Rain/ rip Shield.
The rain/drip shield is required for code compliant marine applications.
The addition of the rain/drip shield does not make The KI weatherproof.
Install The KI where it will be protected from rain, spray, snow or other moisture.
The use of Loctite®Threadlocker 222 (Purple) is recommended to prevent the marine mount from
loosening due to vibration.
The KI should be rotated no more than 1 5º to maintain protection from the rain/drip shield.

The KID Wind/Hydro Charge Controller Instructions
The KI Main Electrical Connections
The following pages contain wiring instructions, diagrams and system images.
WARNIN : Unlike some controllers The KID uses the Wind/Hydro negative and Battery
negative to measure current so they must stay isolated from each other. Wind/Hydro negative
must NOT be electrically common in any way with battery negative or undesired operations will
occur.
Clipper/Load switching is also done in the negative leg. The positive load connection is not
switched.
The only connection on the battery negative input should be the battery negative. The clipper/load and
wind/hydro each have their own negative.
Remove the back cover .
Remove the screw on the middle right of the back cover and gently remove the back cover.
These instructions are for use with units that are not using the wall mount bracket. See page 1 7 for wiring
instructions with the wall mount bracket.
Wind/Hydro Input :Connections from the Kid Clipper output go here.
Load/Clipper: The Load/Clipper Negative connects to the Clip Out terminal in the Kid Clipper. The Load
Positive is not used.
Battery Out: Connections to the battery bank go here.
Wind/Hydro Input, Load and Battery connections all require overcurrent protection. Choose breaker size based
on your wire size. If the breaker is too high an amperage for your wire size it will offer little or no protection.
Torque all connections to 7-9 inch pounds (0.80 - 1 .0 Nm).
Install according to all standards and national electric code.

The KID Internal terminal block
Wiring directly to the KID's internal terminal block .
If the terminal block in the wall mount bracket is not used, connections can be
made to the internal terminal block. Centered directly above the ½” conduit
holes you will find the main 30 amp 6 position terminal block.
This is where you will connect wind or hydro input, Clipper control conductor,
and the battery bank. The battery bank should use 1 0AWG wire (5.26mm2).
Wiring runs from the battery bank should be as short as possible. On the
included wiring diagrams you will notice an external 30 amp circuit breaker in
series with the battery plus wire. This is very important and is a requirement to
meet NEC guidelines for overcurrent and disconnect devices. The battery
overcurrent device regardless whether it is a circuit breaker or fuse must be rated for the C voltage rating of
the battery bank with a minimum of 5000 Amp interrupt rating.
IMPORTANT! Input, output, and load negatives must be isolated. They are not internally
connected.
Inaccurate current readings and damage may result from improper wiring.
Load Positive is internally connected to Battery Positive. Loads are switched in the negative leg.
Fuses incorporated into The KI are not to be used as NEC required overcurrent devices.
The internal KI fuses are for supplemental protection only. MidNite Solar manufactures numerous
circuit breakers and boxes for this use.
The NEC (and common sense) requires a disconnect and overcurrent protection on the input and
battery circuits. It is recommended to use #1 0 AWG wire and 30 amp over current protection for the
input and battery wiring. Overcurrent protection can be a fuse or circuit breaker but the use of a
breaker is best because you get the required disconnect at the same time.
All Midnite Solar din rail and panel mount breakers are rated for 1 00% continuous duty. MidNite
Solar manufactures Baby, Big Baby, Quad and other enclosure needed for mounting the circuit
breakers.
Connect battery positive and negative first. Then connect Input positive and negative. Then apply power by
turning on the external battery breaker. If the polarity is correct, the unit will power up. If the battery cables are
to be removed, remove power by turning off the external breaker and remove the fuse. Follow this procedure
each time the battery is connected/disconnected.
Removing any fuse while it's passing current will cause a spark which will damage the fuse holders!
Breaker sizing:
Breaker size is determined by wire gauge.
1 4AWG = 1 5 amp breaker
1 2AWG = 20 amp breaker
1 0AWG = 30 amp breaker

Inaccurate current readings and damage may result from improper wiring.
Load Positive is internally connected to Battery Positive. Loads are switched in the negative leg.
Wind KI s come pre-installed in the wall mount bracket. See page 11 if you need to re-install your KI into the
wall mount bracket. Select an indoor mounting location that is dry and protected from the elements. Try to keep
the wires to the from the Wind or Hydro turbine, battery bank and Kid Clipper as short as possible. imensional
drawings are provided in this manual to aid in installation. The KI with mounting bracket may also be used as a
drilling template.
High quality wall anchors are recommended for securing The KI to the wall.
Use caution to avoid any pipes or wires that may be running through the walls.
Unit must be installed in a vertical position.
The terminal block in the housing is factory pre-wired to the internal terminal block inside The KI .
Torque field connections to 1 0 in-lbs (1 .1 3 Nm).

Chassis round connection
The screw, nut, and terminal for grounding the chassis are included on all models.
The chassis ground (equipment ground) is required in an NEC compliant system. The chassis of The
KI is isolated from all internal KI circuitry. Wall mount versions have a short wire pre-installed in this
location. It can be found in the wiring area of the wall mount.
Wiring the rest of the system :
Under the “Wiring diagrams” section of this manual there are diagrams showing different system
configurations.
The KI works well with 1 2, 24, 36 and 48 volt systems.
The reason is that the KI has an absolute maximum output of 30 amps. Power is amps X voltage,
so for example, 30 amps output times 1 4 volts (charge voltage) = 420 watts. A 500 watt turbine would
be a good match for a 1 2V system. So this means when you jump to a 24V battery bank, the KI can
process twice the power than if it were connected to a 1 2V battery. In the case of a 48V battery, The
KI can process 4 times the power of a 1 2V battery. Twelve volt battery systems are used in marine,
RV and very small Renewable Energy systems. When possible, it is better to go with a higher voltage
battery bank, but that is not always practical in a mobile application.
The use of the Kid Clipper is required to protect the Kid from excessive input voltage. The Kid Clipper
is factory set to limit turbine voltage to 1 49 volts. It functions as a diversion load when the Kid enters
Absorb and then Float mode, keeping the turbine loaded and RPMs down at a safe level.
uring the Bulk charging phase, the Kid Clipper will help MPPT the turbine output by referencing the
customer supplied wind curve. See page XX for more information on entering wind curve data.

MNBTS Battery Temperature sensor
Battery temperature sensors are employed on many sophisticated chargers in order to compensate the
charge voltage based on temperature. If you are in an area where the ambient temperature is relatively
stable at 25C, you do not need a BTS all other areas can benefit from having a BTS. The BTS raises
the charge voltage when colder than 77 degrees C and decreases the charge voltage above 77
degrees F.
Temp comp is set for lead acid batteries, but is adjustable for other types in the Battery menu.
SYNC MO E:
Sync Mode allows for multiple KI s all on the same battery bank to work together. Each KI MUST
have its own isolated wind or hydro turbine and be wired as the manual shows for a single KI . In
this mode all downstream KI s get there programming and commands from the KI that is selected
as the Primary KI . All things like Float and EQ etc are shared between the KI ’s. See below for
jumper settings.
Note:
o not use the BTS with the
stacking jumpers installed.

Jumper settings for Sync Mode:
In the upper right corner of the circuit board there are two positions for placing jumpers. Unless
stacking three or more KI S in Sync mode leave the jumpers off. The jumpers may be placed on one
pin to be saved for later use. When stacking 3 or more KI s in SYNC mode jumpers should be placed
in both positions on the second and subsequent KI s. The jumpers should be oriented side to side
(horizontally).
Stacking Ports for Sync Mode:
Connect a standard four conductor phone cable (Sold separately) between the MASTER jacks of the
first two KI s.
If additional KI s are to be connected, connect a standard four conductor phone cable (sold
Separately) from the SLAVE Jack on the second KI to the Master Jack the next KI .
Continue in the same manner, Slave jack of one KI to the Master Jack of the Next KI in line. Up to
1 2 KI s may be connected in this manner.
USB Connector do not use in hazardous
environment
Serial communications from the stack port:
