SMA Sunny Island Charger 50 MPPT Solar Charge Controller

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.

SMA from its headquarters in Kassel, Germany, is the world’s largest producer of solar inverters and monitoring systems for photovoltaic applications.  As market leader for solar inverters SMA is setting benchmarks again and again. The leading-edge efficiencies of 98% and new technology ensures maximum yields and the highest user convenience. While SMA inverters are designed in Germany, the Sunny Central, the Sunny Island, and SMA SunnyBoy inverters in the 3 kW to 7 kW range are assembled in their new plant in Denver, Colorado.These inverters qualify for the ARRA recovery act and are UL and cUL listed. SMA launched its own SMA solar academy in Rocklin, California, in April 2011. The best solar power inverter from NASDAQ and Bloomberg listed solar components manufacturers at best price; suitable for all weather conditions.

What does a solar charge controller do?

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.

What solar charge controller do I need?

Make sure you have a charge controller that is large enough to handle the amount of power and current produced by your solar panels. Typically, charge controllers come in 12, 24 and 48 volts. Amperage ratings can be between one and 60 amps and voltage ratings from six to 60 volts.

How many solar panels does it take to charge a 100ah 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.

How do you calculate solar panel to battery?

Take the power produced by the solar panels and divide by the voltage of the batteries. For example: Example: A solar array is producing 1 kw and charging a battery bank of 24V. The controller size is then 1000/24 = 41.67 amps.

What is the difference between MPPT and PWM charge controller?

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.
