Solar use recharging cycle. (5 Viewers)

I had a lot of help from the Fun community recently with the setting up of my solar and lithium. I thought I'd start a new chat regarding the use of the various things and recharging. Currently we're enjoying a decent bit of sunshine so that's been useful working things out.

My shunt reading this morning was 74% as shown. From what I've read bringing the ah back to zero is goal. Is this correct? Are there any other stats from this screenshot I need to consider?

It is.

Charge current to zero, and SoC % to 100%.

All things being equal, they amount to, more or less, the same thing.

So if there's no alternative power source to charge, hookup, or alternator because we're not driving and the overall charge is dropping each day, what percentage would you expect our appliances to fail to work?

One of the advantages of LiFePO4 lithium batteries is that the voltage stays very constant as the batteies discharge.

All of the appliances on our Sterling Power batteries continue to work right down to the point at which the BMS switches off the batteries to protect them.

Not recommended to do that too often !!

We actually have a 200ah LiFePO4 battery, so good to know we can take it that far. As it's a new installation it's going to take a bit of time to figure it out. The good thing is all the gas stuff is still here if we go to far.

You may find if you allow your battery to get that low that the BMS turns it off that you may have difficulty recharging it again, personally I'd be finding some method of charging it when it gets down to around 15%, go for a drive or get on hookup.
