Understanding energy storage is becoming increasingly important, as customers in fire-prone areas experiencing Public Safety Power Shutdowns desire a way to make their homes more resilient. This course is a good introduction to this topic. I especially appreciated the energy consumption spreadsheet provided free of charge with this course.

This course have been an elevation in knowledge as far as my career as an installer is concerned having gone through the difference between both storage systems.

by Shaun Dorman 03/30/2020

Lion is the current best technology available in remote parts of Africa with a unstable grid , In south Africa specifically we have what we call Load shedding where the grid turns off for 2-4hours daily . 5 Years ago Lead acid batteries along with a charge controller (Charging from the grid during non shedding times )this howerever is a poor metod to charge the batteries . 5 years later new tech came out like L-Ion batteries technology came out the likes of tesla/LGChem etc . These batteries require far more expensive BMS example The cheaper inverter technology does not suit L-ion and other . further videos would be appreciated with regards to BMS Compatibilities .

Great course, kept me glued to the screen, loads of information on different system types available.

by Ricarte Nunez 02/25/2020

The contents are great starting with introduction and the client qualification if the latter needs a battery for its PV system. The spreadsheet was a great tool in the calculation of Watt-Hours used per day which is essential in the calculation of the capacity of the PV system. Students may appreciate the topics presented for about an hour of listening to the lecturer.
