MPPT charge controller
How does the MPPT work?
The MPPT charge controller operates at extremely high audio frequencies which are of the 20 to 80 KHz range. The MPPT charge controller compares the output of the solar panels with that of the battery voltage. Then it determines the power the panels need to produce to charge the batteries.
Most of the MPPT charge controllers have an efficiency level of 92 to 97 percent in the conversion process. You gain power in winter by almost 20 to 45 percent and 10 to 15 percent in summer. The actual gain depends on a lot of factors like the temperature, weather and the battery's state of charge.
The grid tie systems that are becoming popular day by day with the solar panels being available at affordable prices have inbuilt MPPT charge controllers. The efficiency of the MPPT conversion in the grid tie system is somewhere between 94 to 96 percent.
The ideal conditions for optimum performance
The MPPT charge controller works best during winter and on cloudy days when there is requirement for extra power. During cold weather the sun does not shine brightly and there is a greater need to recharge the batteries. The solar panels should be fitted with the MPPT if you want sufficient amount from less sunlight. Also when your battery's charge is low the MPPT feeds more current into them.
The benefits
The advantage of using the MPPT charge controller is that they operate at extremely high audio frequencies which are designed with very efficient transformers and small mechanisms. To design these high audio frequencies is a very risky thing due to problems that the circuit can face while broadcasting such as in a radio transmitter that causes interference. Here it is very important to remove all noise.
Another advantage of using the MPPT charge controller is that you save on your wiring charges. The smaller gauge wiring can be used, The solar panel array can be very far from the charge controller. So it is essential to reduce the cost of wiring. When the voltage is doubled the current that is passed through is reduced to half which means you can use less wire.
Digital MPPT charge controller
The MPPT charge controller is the only solar charge controller that can match with solar panels of any size along with any type and size of battery. The Outback MX60 is one of the charge controllers that can match up to the high voltage panels made for the grid tie applications and also for battery charging applications.
The Outback MX60 MPPT charge controller helps your PV system to perform at the highest level. The Outback MX60 gives you the advantage of using a high output voltage PV array with a low voltage battery. For example you can use a 60 volt PV array to charge a 24 volt battery.
This requires less wire and reduces power loss from the PV array to your battery location which can help maximize your PV system's performance. The Outback MX60 charge controller is user-friendly with a backlit LCD display used for monitoring and programming purposes of your system.
The Outback MX60 can be connected to the Outback Mate System Controller that allows 8 MX60 controllers to be monitored from at least 300 feet far location. The Mate also has a port to connect to a PC for system monitoring and data sorting.
