1 x SOLAR CONTROLLER
Ideal for use on both automotive and deep cycle batteries. Featuring intelligent electronics that control DC appliances without over discharging the battery .Ideally suited to solar panels producing up to 20A, this is a highly advanced controller delivers a comprehensive 3 stage charge ( Bulk , Absorption & Float ). Ideal for caravans or boats where multiple solar panels.
The SBC-7120 is feature packed and the various threshold voltage limits can be arbitarily adjusted thanks to its microprocessor control.
The LCD cycles through each parameter, displaying in turn: the mode of operation, battery voltage, PV voltage, PV amperes, today's ampere hours, yesterday's ampere hours and the day before's ampere hours.
A dual-colour LED provides a quick visual status of the battery state.
Heavy duty terminals are provided to connect heavy guage wire (up to 10AWG) to the unit.
Internally, a 30A automotive-type blade fuse provides overload protection. A spare 30A fuse is provided.
SBC-7120 is a high quality PV charge controller, at a price point almost unrivalled in its class. The unit provides an LCD readout of the various system statuses.
The unit automatically determines the state of the battery and applies an appropriate charging regime. It uses a three stage Bulk/Absorption/Float charging system. The Absorption and Float voltages can be set anywhere from 12.0v up to 16.5v. When the battery voltage drops below the float level for more than 5 minutes, the unit will commence bulk charging. Once the absorption voltage has been reached, it will hold the charging voltage constant for one hour, then switch to float mode.
For a typical day consisting of 5 hours of useful sunlight, and with enough panels to provide 20A of short circuit current, the SBC-7120 can theoretically deliver up to 100 AH of charging current per day. For a 12 volt battery, this equates to at least 1200 watt-hours of charge per day though the controller.
At near full load, the integral chassis/heatsink becomes very warm to the touch. The heating is less pronounced when the PWM charge is at 100% duty cycle, which vastly reduces power dissipation in the MOSFETs.
Its quiescent current draw of 30mA makes it unsuitable for small battery banks (less than 10 AH) due to the overnight discharge. The microprocessor and battery status LED requires constant power to keep running. If the battery is disconnected overnight, the rolling three-day ampere-hour statistics will be lost.

|Maintains the Battery in a Fully Charged State
,,,Any battery left unused will lose its charge over time. The solar controller can be connected indefinitely to the battery to keep the battery fully charged by using a process called floating. This means the controller will stop charging when the battery is full and will automatically start charging the battery as required.
|Protects your Battery from Solar Power Discharge
,,,Solar panels are known for converting the sun's energy into electric power; however less known is that solar panels can also drain power. The solar controller prevents the solar panel from draining power out of the
