The Brat Solar Charge Controller Instructions
Troubleshooting
Problem
Possible Cause(s)
Solution
Batteries do not charge
Incorrect system Voltage selected
Set S1 -3 to correct system voltage
Not enough sunlight reaching the panels
Reposition panels, check for shading
wiring error
Verify all connections

Glossary
Absorb............................... A charging state where the battery is held at the absorb volt setting for 2 hours.
Amp................................... A measurement of electrical current.
Amp-Hour.......................... A measurement of electrical power. Amps x Hours.
Auto-EQ............................. An equalization charge that will attempt to start every thirty days.
AWG.................................. American Wire Gauge.
BATT..................................Battery or Battery Bank.
Bulk....................................A charging state where all available power goes to the battery until it reaches
the Absorb voltage setting.
EMI.................................... Electro Magnetic Interference. Electrical noise.
EQ..................................... Equalization charge. An extended charge to match charge level on battery cells.
Float...................................A charging state to maintain a fully charged battery.
LED....................................Light Emitting Diode.
LVD.................................... Low Voltage Disconnect.
OVD................................... Over Voltage Disconnect.
Minus................................. Negative power connection
Parallel...............................A mode where the Load circuit is used to increase The Brat's charging capacity.
Plus....................................Positive power connection.
PV...................................... PhotoVoltaic.
