Q: what is the difference between PWM and MPPT controller?
What is the difference between a PWM and MPPT charge controller?
Pulse-Width Modulating (PWM) charge controllers use complex algorithms to determine the amount of charge going to a battery and slowly taper off charging as the battery becomes full. One of the greatest advantages of PWM controllers is that they have been around for many years, are cheaper, and are available in a wider variety of sizes for different applications. Some drawbacks of using a PWM controller are that when sizing a system the controller must match the voltage of the battery bank, and PWM controllers are normally limited to 60 amps maximum.
Multiple Power Point Tracking (MPPT) charge controllers take into account the fact that a solar panel sometimes puts out variable output due to weather conditions, and can automatically match the voltage it is producing to the voltage of the battery in order to maximize charging efficiency. MPPT controllers have the capacity to handle more than PWM controllers and can go up to 80 amps, and allow for more expansion within the system. The main drawback is that MPPT charge controllers are much more expensive than PWM controllers.
When choosing between a controller it is important to gauge the size of the system. At a smaller scale, the difference in efficiency between PWM and MPPT controllers may not be noticeable enough to justify the price difference between the two controllers, but on very large systems the efficiency plays a much larger role in how well the system will perform.
Q: What is the RS232 communication function?
A: it is for setting and checking the parameters of wind turbine, battery, controller from computer. Software free.
Q: What is the USB data logging function?
A: It is designed for collecting parameters of wind turbine, battery, charge controller from controller into USB flash disk. You can check it on any others computer.
Q: can I buy 1 pc sample? what is the price?
A: of course, you can buy 1 pc, we always welcome clients to buy 1 pc as sample to make the test firstly. Then they will make sure this is good choice or not for their system.
The price for 1 pc sample will be same as for bulk order, no any extra charge.
Q: can I get a free sample for testing?
A: sorry, we don't supply free sample, since we provide each controller based on clients system detailed parameters, to make sure this controller will work very well, so it is customized for you especially, we have to ask for the cost.
