Description
AC and DC coupling in perfect interaction and from a single manufacturer: the all-purpose SMA Sunny Island Charger 50 MPPT Solar Charge Controller. Its broad DC input voltage range makes configuration possible for almost any PV module.
Thanks to the integrated MPP tracking system, the charger guarantees an energy yield between 15 to 30 percent higher than that of conventional shunt charge controllers. Unique in charge controllers of this power range: the high protection class, fanless operation and broad temperature range enable its use even under extreme climatic conditions. Easy installation and automatic control through the SMA Sunny Island Charger 50 MPPT Solar Charge Controller make commissioning super simple.

SMA is considered somewhat of a legend in the solar world and manufacture some of the best quality and most reliable solar inverters, charge controllers and other components on the market backed by an excellent service team and guaranty conditions.
A charge controller or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery.
Charging your battery at 12 volts and 20 amps will take five hours to charge a 100 amp hour battery. By multiplying 20 amps by 12 volts, 240 watts is how big of a panel you would need, so we’d recommend using a 300w solar panel or 3 100 watt solar panels.
The basic difference is: With a PWM controller the current is drawn out of the panel at just above the battery voltage, whereas. With an MPPT controller the current is drawn out of the panel at the panel “maximum power voltage”. Basically the MPPT controller is a “smart DC-DC power converter”; up to 25% more efficient.
