The KID Solar Charge Controller Instructions
MNBTS Battery Temperature sensor
Standard on Marine versions, optional on all others. The published ratings of most batteries are made
at 77 degrees F (25°C). Mother nature as well as man doesn’t always allow the ambient temperature to
hover around 25°C while charging batteries. 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 this temperature, you do not need a BTS
(Battery Temp Sensor). If you live in Alaska or in the Sahara desert, you will want a BTS. It will prolong
the life of your batteries. 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.
Stacking:
Twin Mode:
The KID stacking port is used for two things. When your power requirements grow and more
charging current is required, you can add a second KID and have it act like a 60 amp controller. This
requires that the PV input and battery outputs of two KIDs be paralleled, You accomplish this outside
of The KID in a suitable junction box. See pages 22 and 40 for stacking set-up. Make sure to use
wire and breakers of suitable size for each KID. Since you will now have a 60 amp output capability,
you might think that a single 60 amp breaker after combining the output is acceptable? However,
each KID accepts 1 0AWG wire max. A 60 amp breaker does not protect 1 0AWG wire, so two 30 amp
breakers will be required. The same situation exists for the PV input. Make sure that wires are not too
small for the overcurrent devices.
1 4AWG = 1 5 amp breaker
1 2AWG = 20 amp breaker
1 0AWG = 30 amp breaker
8AWG = 50 amp breaker
6 AWG = 60 amp breaker
Note:
Do not use the BTS with the
stacking jumpers installed.
