MidNite Solar Kid Manual

The KID Solar Charge Controller Instructions
The KID Main Electrical Connections
The following pages contain wiring instructions, diagrams and system images.
WARNING: Unlike some controllers The KID uses the PV negative and Battery negative to
measure current so they must stay isolated from each other. PV negative must NOT be
electrically common in any way with battery negative or undesired operations will occur. Load
switching is also done in the negative leg. The positive load connection is not switched.
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 20 for wiring instructions with the wall mount bracket. The connections for PV input,
Load 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.
PV Input: Connections from the solar panels go here.
Load: Connections to the controlled load (load control function).
The Negative lead is switched. Load positive is connected to battery positive.
Battery Out: Connections to the battery bank go here.
PV 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 the standards and national electric code.
Important! All cable used must be suitable for the Hazardous Locations area.
