Charge Control Systems 1-30 Amps

PWM and direct charge controllers are amperage limited and voltage tolerant.  Higher the voltage of the array and higher the battery bank voltage will allow more controller capacity.  The capacity of a 10 amp PWM charge controller in a typical maximum 50 volt system works like this.

  • A 12 volt battery bank is limited to about 120 watts of solar panels

  • A 24 volt battery bank is limited to about 240 watts of solar panels

Direct solar charging of 12V batteries with a solar panel does not use a controller at all.  The construction of the panel inherently limits the voltage and current to within the tolerable range for a 12V battery, including lithium.  The panels are limited to about 10Watts, or about 0.6A at 13V-14V.

5W Solar Battery Charger and Maintainer

DESCRIPTION

Equipped with premium monocrystalline solar cells, the Renogy 5W Solar Battery Charger and Maintainer manages your 12V lead-acid battery in daylight conditions by converting the sunlight into usable electricity and maintaining a healthy state of charge. The built-in MPPT (Maximum Power Point Tracking) charge controller intelligently manages the charging process and improves the charging efficiency by 10%-20%. The plug-and-play SAE connecter and included adapter cables make the solar battery charger maintainer a versatile fit for most applications.

Note: For some makes or models of vehicles, the cigarette lighter port may not operate when the ignition is turned off. In such cases, please connect the solar battery charger maintainer to the battery directly.
