60 V charge controllers
Charge controllers are essential components of any solar power system that incorporates a battery bank. A good model can make your system safer and extend the life of your battery. A 60 V solar charge controller can be a good choice for both large and medium PV systems, depending on the amperage.
This important device controls the charging process, just like its name suggests. Typically, a 60 V solar charge controller will allow your system to:
A solar panel system with a voltage greater than 60 volts is beyond the capabilities of a 60 V charge controller. Verify the open-circuit voltages of your solar panels using the information provided in the product specifications. If your array's panels are wired in parallel, the system's voltage will be the same as that of a single panel. When panels are wired in series, the voltage increases while the current remains constant.
Multiply the voltage of your battery bank by the amperage of the controller to find out how many panels you can connect to your 60 V charge controller. For example, if you have a 48 V battery bank and a 60 V charge controller with a 40 A rating, you can run a system with six 320 W solar panels (48 * 40 = 1920).
One of the most important decisions to make when selecting a charge controller is whether to use PWM or MPPT.
In terms of cost, a 60 V PWM solar charge controller would be the best choice. Because of the simplified design, controllers of this type tend to last longer. A PWM charge controller has a lifespan of 10–20 years. Yet, efficiency is sacrificed for low cost and long life. A 60 V PWM charge controller would only be about 75% to 80% efficient and give you less control over the charging process. Furthermore, when the panel and battery voltages are different, this type of controller loses too much power.
If you're looking for a 60 V solar charge controller for sale, expect to pay more for one that employs MPPT technology. In return, you have greater control over the charging process and a higher efficiency of up to 99%. Depending on the brand, these controllers may last anywhere from 10 to 15 years. You can use a much lower voltage battery with a 60 V MPPT charge controller, saving on wiring.
