I have a similar issue in the winter. I don't worry about charging LFP to 100% every day. I do manage how low they will go before charging from the grid because I want some reserve available if we get a power outage in early morning.
Are you referring to the Pytes V5 or the Pytes 48100R? The V5 has a different form factor and I saw one post which said the V5 uses CATL cells. None of the Pytes literature I have seen gives any clue?
Sorry, my mistake; that model number was for the 48100R; the V5 uses a cell with UL 1973 file # MH64238, which is also a REPT cell, but it doesn't specify the exact model.

What I like so far about the Pytes is that the company has a good USA presence, online documents, downloads, firmware, will respond to email and also answers the phone for tech support. And, lastly the 8 racks I have installed all started up at 50% charge six months after manufacture, no issues, errors, etc.
Now its time to see how they perform over the coming years.
The inside wall of my garage where my SolArk is mounted has no room so I am going with the exterior enclosure just outside that wall. I like all the features which @glandpuck mentioned plus the integration with my SolArk.
