IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS-THESE INSTRUCTIONS CONTAIN IMPORTANT SAFETY AND OPERATING INSTRUCTIONS FOR

THE KID CHARGE CONTROLLER MODEL NUMBERS

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.

MNKID-HWB, AND MNKID-HWW.

GENERAL PRECAUTIONS

:
WORKING WITH OR IN THE VICINITY OF A LEAD ACID BATTERY, SEALED OR VENTED IS DANGEROUS. VENTED
BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. FOR THIS REASON, IT IS VERY
IMPORTANT THAT BEFORE SERVICING EQUIPMENT IN THE VICINITY OF LEAD-ACID BATTERIES YOU REVIEW AND
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.

Do Not expose to rain or snow. NEVER attempt to charge a frozen battery.
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
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. Dropping 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 15 minutes and get medical attention immediately. Baking soda
neutralizes battery acid electrolyte. Keep a supply near the batteries

Do not smoke around batteries.

remove the negative terminal from the battery first

.

Do 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 14-10 gauge AWM wire. Select the wire gauge used based on the protection provided by the circuit
breakers/fuses.
this manual for breaker/fuse/GFDI sizes and model numbers.

WARNING:This unit is not provided with a GFDI device. This charge controller must be used with an external GFDI 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. Double 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 KID:

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 KID. 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 #10 (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 KID may also be used as a template.
The casting on The KID is 8.65” (219mm) x 4.54” (115mm) 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 KID has a depth of 1 .45” (37mm) from the mounting flange to the
back surface.

Important!

behind The KID after mounting to prevent overheating.

A minimum of 2" (50.8 mm) free space is required

The KID mounted in the wall

See page 1 3 for wiring
instructions.

IMPORTANT!

Do not mount in a zero clearance
compartment. Overheating may
result. 3" clearance in front of fins is
required. The KID produces heat in
normal operation. Free flowing
ventilation around The KID is
required to prevent overheating and
shutdown. This is especially true in
hot environments.

The KID Wind/Hydro Charge Controller Instructions

2. Surface mount.

The Wind KID comes pre-installed into the wall mount bracket. These instructions apply to KIDs that
are field installed into the wall mount bracket. 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. 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.

Locate and twist out the
knockouts in the bottom
section of 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 KID. The wall mount adapter is intended to
use #10 (5mm) screws.

Make the wire connections to the terminal block inside The KID, replace the back plate and then
assemble The KID to the wall mount adapter. Use the #10 x ¾” Plastite screws provided to secure
The KID to the wall mount adapter.

RIGHT:

IMPORTANT!

Do not mount in a zero clearance
compartment. Overheating may result. 3"
clearance in front of fins is required. The KID
produces heat in normal operation. Free

to prevent overheating and shutdown. This is
especially true in hot environments.

The rain/drip shield is required for code compliant marine applications.
The addition of the rain/drip shield does not make The KID weatherproof.
Install The KID 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 KID should be rotated no more than 1 5º to maintain protection from the rain/drip shield.

The KID Main Electrical Connections

The following pages contain wiring instructions, diagrams and system images.

WARNING: 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
Load/Clipper:

Positive is not used.

Battery Out:

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 Wind/Hydro Charge Controller Instructions

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
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 DC 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

to

The KID Internal terminal block

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 KID are not to be used as NEC required overcurrent devices.
The internal KID 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 #10 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
