Thank you for this article, although, in my opinion it falls short of identifying the best way to prolong the health of a battery back up system.
The strong advice of EV manufacturers and even Apple iPhone is to NEVER, OR AT LEAST RARELY WHEN YOU ARE PLANNING A LONG TRIP, CHARGE YOUR LITHIUM ION BATTERY TO 100%!
I have had my LG Chem battery for 4 1/2 years and only charge it to 80%.
I do the same for my Electric Vehicle and my iPhone. Regularly charging these batteries to 100% will shorten their lifespan…PERIOD!
I have tried for years to get responses from the Solar battery industry, and this magazine as to why they fail to educate customers to this fact and have yet to receive a reply?
Oh My!

In reply to Rose and Clifford Hare.

Yeah, no, that’s just not the case. First of all, what “inverter system” costs 20.000 dollars? A 3000VA inverter costs about 1.500 dollars, and that powers more than “5 items”. 10kWh of battery storage are around $3500-4000.
I got 30kWh installed 8 years ago and the system is still going strong, last time I checked I still got over 29kWh out of a full charge (which is probably partly because these rack units have a buffer). The batteries have effectively doubled my PV yield, and the entire system (+PV) paid itself off already. Heating the house with geothermal heatpump and absolutely loving it. But I get that burning stuff was mankinds greatest invention and is so ingrained in our culture that it’s really hard to get away from that.

wooh having just spent over $20,000 for an inverter system that can only power 5 items,which was eye opening in itself to now reading the batteries might last 10 years is all,well the installers said for another $20,000 I had room to put another battery in the box to power more things just eye opening we have a 926 sg ft house built in 1958 and for all that expensive money they won’t last as long as the solar panels do!
