Guess I need to upgrade my inverter then because my load and DoD of my LFPs are essentially being dictated by how quick I can charge it at this stage. Or how slow I can charge I should say.
Curious... Battery size? Load size? What DoD do you usually run to?
 
@AlphaJohn - What do you use to monitor it?
Is there a way to shut down the system before it reaches a certain battery voltage?
Right now we just guessing because we dont want to reach the BMS cutoff.

I have Sonoff's to see in & out via Home Assistant:

As for when it hit close to empty no don't use anything for automation as base load 120W can easily handle 4 hours without a fuss. We normally home for high use and for that we gauge via a V meter eg:

That said, I have yet to see my Sako battery drop below 26.4V even with 4 hour sessions. Battery just take longer to charge back up. My battery does have a % graph but that is inside a box so not of much use.
 
When gaming yes.

Base doing nothing is 120W during LS and 70W when we out of LS.

120W is to ensure fan kicks in.
Makes sense then why they charge up so quickly then... My wife and I both work from home so the batteries are constantly being loaded. Also have cables running to power our TVs.

200 Ah in total. Have a spreadsheet to calculate load - Its a bit of a guessing game but I calculate between 150 and 250 Watts during work hours. It can't be more than 360W cause I've never had the 50% load bar appear on the Mecer. I reckon I am discharging to maybe 75% DoD if its full when LS kicks in. If thats the case, it will take 5 hours to charge back up at 10A, but it takes about double that time because I am still using it while it chargers most of the time. Unless I'm sleeping.

Thanks! I reckon i'll get one of these with the colour indicator so the wife can see... red means stop.Screenshot 2022-10-19 at 13.41.50.png
 
Here's a nice shot of the inverter switching straight to float charging after LS, then just about getting through a full charge cycle before LS strikes again. The later took about 12 hours :/

Loadshedding be gone once more!

Finally installed again at new place, now I'm waiting my battery from China to add to the current batteries
