This informative webinar features SunWize Senior Engineer Rob Rallo, who has over 25 years experience designing off-grid solar, hybrid, and battery backup power systems.
This educational webinar will cover several topics related to PWM charge controllers, MPPT charge controllers, and 60-cell solar modules.
The first portion of the webinar will discuss voltage set points, temperature effects, and voltage losses between the array and solar charge controller. We will review appropriate calculations and best-practices related to these topics when designing off-grid solar systems.
The next portion of the presentation will cover appropriate design considerations for 60-cell (24V) solar modules when integrating into battery based systems. This section will include calculations for charge controller and battery bank voltages when using 60-cell modules.
Finally, we will discuss performance differences between PWM and MPPT charge controllers. When deciding what controller to use, it’s important to understand the limitations of each controller type, their advantages/disadvantages, different capabilities & features, as well as understanding the correct amount of power you can expect to produce with each type of controller under various conditions.
Make sure you are adequately sizing your system’s exact equipment & specifications with appropriate power output calculations, temperature effects, and line loss considerations!
