The KID Solar Charge Controller Instructions
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. creates a very accurate battery State Of Charge meter within The
KID. There is some set-up before using the WBJr and it will be necessary to enter values for Battery bank size in
Amp-Hours, battery efficiency, Battery temperature compensation reference and percentage of change per
degree C. Refer to the battery manufacturer's documentation for these values.
After installing the Whiz-Bang Jr. one full charge cycle (until float is reached) is required
before accurate readings may be obtained.
To enable the WBJR on The KID:
Press Main Menu button.
Scroll to the right, Until Aux is in shown in brackets, <AUX> Press Enter.
When the display shows FUNCTION: press the up or down arrow button until WBJR is selected.
Press the Right button until the * is next to Auto.
Press the SETUP button to setup the SOC portion.
Entering battery bank information:
Battery Capacity: This is the first screen after you press the SETUP button. Battery Capacity
per battery can be obtained from your battery manufacturer's spec sheet. This setting is the total
capacity of the battery bank and will largely depend on how your battery bank is designed.
Use the up and down arrows to adjust the capacity of the battery bank. Press the Right arrow
to go to the next set up.
Battery Efficiency:
Batteries are not 1 00 percent efficient and some loss does occur. This setting will improve
accuracy by taking this inefficiency into account. Battery efficiency will be different between
Manufacturers and will lower with age, 94% is a good starting point for most battery banks.
Your battery bank will reach 1 00% charge as soon as it hits float stage.
Use the up and down arrows to adjust the battery efficiency of
the bank Press the Right button to go to the next set up.
Battery Temperature Reference: This is a reference temperature used as a starting
point for temperature based charging voltage adjustments. This is the temperature at
which the battery manufacturer considers the temperature compensation to be zero,
usually this will be 25°C, but it may vary by manufacturer and battery type.
Use the up and down arrows to adjust the battery temp ref of the bank.
Press the Right button to go to the next set up.
Battery Change %: The change of battery capacitance in percentage above and
below of the temperature reference, usually will be 1 %.
Use the up and down buttons to adjust the battery capacity change percentage.
Press the SAVE button to save the whole set up.
Press the Status button and then scroll to the right to view the WBJR SOC screen.
This screen will show you the Output current going straight to the batteries after the loads, also
the SOC in percentage of the battery bank and also the Amp hours remaining on the batteries.
