MidNite Solar Kid Manual

The KID Solar Charge Controller Instructions
Manual EQ- Manual Equalize it will do a single EQ cycle on the batteries if
enough power is available from the solar source.
Auto EQ- Auto Equalize allows the batteries to go through an EQ cycle in the days
interval programmed in the unit, defaults to 30 days, Days can be adjusted by the
user for the required interval for the specific batteries. Day count will be reset back to
day 0 every time the unit loses power. If not enough power is available in the day an
EQ is scheduled, it will skip and wait for the next scheduled day.
To set EQ parameters:
Press Main Menu and select Battery,
Go to EQ and press Enter,
Press the SETUP Button to adjust the EQ Voltage and Time.
To start a manual EQ cycle:
Press Main Menu and select Battery,
Go to EQ and press Enter,
Select START,
The EQ Cycle will begin.
Battery Charge Stages and Meanings / Setup
Bulk MPPT
This stage of The KID means; that The KID will be putting out as much current as it can trying to charge
the batteries to the absorb voltage set point. This is also known as constant current mode.
Absorb
This stage means that The KID will maintain the absorb set point voltage until the batteries are
charged or it reaches Float stage. At this stage The KID is not putting out maximum current, as
that would increase the battery voltage over the Absorb set point. This is also referred to as
constant voltage mode. The battery is considered “full” at the end of the absorb charge cycle.
The absorb time is proportional to the bulk time. (i.e. the time bulk takes to reach the
absorb voltage.) The battery it’s considered “full” at the end of the absorb charge cycle.
Float
The Float stage follows after the Absorb stage has been completed. At this point the
batteries are considered full and The KID's incoming current is adjusted to maintain a
full battery as system loads turn on and off.
Equalize
The intent of an equalization charge is to bring all battery cells to an equal voltage by a
deliberate overcharge. The goal is to return each battery cell to its optimum condition
through a series of voltage controlled chemical reactions inside the batteries.
