Morningstar Solar String Calculator

Morningstar Corporation, a company known for its high quality charge controllers has released a string calculator for estimating the proper sizing and configuration of solar panels when used with the Morningstar charge controller product line. One of the most difficult aspects of setting up a battery based system is the compatibility between the various system components which include solar panels, charge controller, batteries and possibly an inverter. The calculator takes into account the solar panel and battery specifications as well as information on the ambient temperatures to help you not only select the right charge controller for your project but to string the system properly to ensure proper function of your off-grid solar electric system. The results of the calculator show you the number of solar panels that may be wired in series and parallel to safely operate within the charge controller specified range. All you have to do is either select the solar panel you will be using from the list, or manually enter the specifications of the solar panel if you don’t see it on the list, enter the model of the charge controller, and enter the battery voltage and ambient temperatures and presto! The calculator will spit solar panel configuration recommendations. I’m glad Morningstar took a proactive approach to help customers figure out a confusing aspect of purchasing and using the right charge controller for their project. What do you think?
