INTORDUCTION 

We have many solar battery charge controllers - up to 50A - but they 

only work on one battery bank. This unit will charge TWO house battery 

banks or one house bank and your motor start battery as well. Too often 

the motor start battery is forgotten if you are camped in the one spot for 

a long time.   

Features: 

Will charge 2 completely separate battery banks at the same

time or even single battery. 

Works with 12V or 24V systems

Highly efficient PWM (Pulse-width modulation) charging

system 

Provides up to 10A charging current (Limited by size of your

solar panels) 

Electronic protection from over charging short circuit or

accidental reverse battery connection 

Specifications: 

Max solar input voltage: 30V (12V system), 55V (24V system)

Battery input voltage range: 8-15V (12V system), 8-30V (24V

system) 

Max output current (both channels): 10A

Overnight self-consumption: 4mA

Dimensions: 153 x 76 x 37mm
