The Sunforce 7-amp solar charge controller handles up to 105 Watts of power from a 12-volt solar panel. This controller prevents any overcharge of a 12-volt battery. LEDs display charging and charged status.
A solar charge controller regulates the voltage and current or amperage coming from the solar panels going to the battery and prevents the solar panel from overcharging the battery.
A charge controller is the layer of protection for your solar system. They are designed to protect the battery from overcharging and to prevent reverse current to panels during the night. They also regulate the voltage that comes from the solar panel which can vary with the sun conditions and may peak as high as 26 volts for a 12 volt nominal output solar panel. The solar charge controller manages the charging of your 12V battery. Once the battery is full the solar charge controller stops the respective solar panel from overcharging your 12V battery and prevents reverse current. When the charge of the battery goes down, i.e. voltage goes down, the charge controller will sense this and allow the solar panel to recharge the battery.
Yes, each 7-amp solar charge controller has a blocking diode installed within the wiring to prevent reverse current.
No, the 7-amp solar systems are designed to be permanently installed.
A solar charge controller is needed when you have 15 Watts of solar energy or more.
The 7-amp solar charge controller has a maximum input of 105 Watts from a solar array. The 7-amp solar charge controller is designed for a 12-volt system only. 12-volt nominal output solar panels should be connected in parallel to keep the voltage at 12 Volts.
Please note that since not all batteries reach 14.2V, the green LED light may not always come on. It is always a good practice to verify your battery status with a voltmeter or indicator. Your battery may be fully charged at a level of 13V, plus or minus, and not require further charging.
Yes, this charge controller comes with a 1-year limited warranty.
