install "whole home" backup systems, but we need to dump a load that is on
a downstream subpanel. A common need is to shed pool equipment like
electric heat pumps and pool pumps when utility power is lost. In other

For many LFP batteries, while some say you can charge at the C1 Rate, most
want you to charge at the C2 or C3 rate.
While you don't have to get them full all the time like lead, as long as
you are cycling regularly, it is still a good idea to get them to full
regularly. Now if they are a backup
Hi Mac,
Below is what I use from Schneider for 200A grid-tie. They finally made
it easy, not inexpensive though. Offgrid version firmware out in the
fall.

Jay, I do not know/use this brand. Got this off the internet. Looks to
me like they are telling you max charge is 100A but max life is 30 - 50a
charge.
only a 5 year warranty so Good Luck !

Hi Jay and all, I belive Steve meant C/2 or C/3; just a typo. My oldest
set of LiFe is almost 10 years? It has a fastest charge rate of C/0.2
because the 10 kWh is charged by 1.6 kW solar. These batteries are doing
