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 covers several topics related to PWM charge controllers, MPPT charge controllers, and 60-cell solar modules.

The first portion of the webinar discusses voltage set points, temperature effects, and voltage losses between the array and solar charge controller. We review appropriate calculations and best-practices related to these topics when designing off-grid solar systems.

The next portion of the presentation covers appropriate design considerations for 60-cell (24V) solar modules when integrating into battery based systems. This section includes 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.
