Epever battery settings. Bluetooth app?

[Aussie Collie]

I've just connected my 5415an controller to my two 12v, 100ah lithium batteries in series.
I have the ble-01 connected and I'm going through the battery settings.
So far I have these settings. Some are default, some I have put in:

Boost duration(m) 120 (default)
Equalise duration 0
Temp. Comp. Co-efficient 0
Over Voltage Disconnect 31.2 (default)
Over Voltage Reconnect 29.4 (default)
Equalise Charging Volt. 28.4
Boost Charging Volt. 28.4
Float Charging Volt. 27.2
Boost Recon. Charge Volt. 26.4 (default)
Charging Limit Voltage 29.2 (default)
Discharging Limit Volt. 21.2 (default)
Low Volt. Disconnect 22.2 (default)
Low Volt. Reconnect 25.6 (default)
Under Volt. Warning 24.0 (default)
Under Volt. Warning Reco. 25.6 (default)

Could somebody please tell me if any of these settings need changing, which ones and what to?

Did you fully charge both 12V before you put them in series? If not, you need to do so, and you may need to do this periodically.

Settings look fine.

Thanks.. Yes, did that. All good that way.

The settings I'm most worried about are the "Boost Duration" and "Charging Limit Voltage"

It really depends on how much current you're pushing. However, in retrospect, 2 hours is usually longer than needed. See how long your absorption cycles take to drop to 0.05C and set your boost duration accordingly. My guess is closer to 30 minutes.

and "Charging Limit Voltage"

I don't know what that means without looking it up in the manual.

Well, it depends on how you want to do things, doesn't it?
Me, I have much lower charging limits, due mainly to the fact that I like to not fully charge my (LFP) batteries - I can afford it, I draw very little - and that the (Pylontech) BMS on them goes red in the face LEDs if they reach 28.4 anyway.
So I have 27.8 as max... anything.

27.8V will absolutely take a LFP battery to 100% SoC depending on tail current.

I was wondering how you are making out with your scc settings. I have the epever also and the amps stay to the max (30) until the batteries reach 27.5 (under Charge) then cuts off all charging until it goes down to 26.5 (no Charge, a little load, 50 watts). I thought the amps should go down when the batteries are reaching full charge. Do you experience similar issue?.

 

[Jim Burrow]

The charge amp will drop down to 1 or two amps. then will go into a float.
I personally don't have wi-fi and the only battery readings I get is from the LED screen on my 2424lv which is basically, the battery voltage, current and wattage.

Setting up EPEvers for 24v 8s LiFePO4. This would be my settngs.

Boost duration(m) 180
Equalise duration 0
Temp. Comp. Co-efficient 0
Over Voltage Disconnect 31.2 (default)
Over Voltage Reconnect 29.4 (default)
Equalise Charging Volt. 28.4
Boost Charging Volt. 28.4
Float Charging Volt. 27
Boost Recon. Charge Volt. 26.4 (default)
Charging Limit Voltage 28.4
Discharging Limit Volt. 21.2 (default)
Low Volt. Disconnect 22.2 (default)
Low Volt. Reconnect 25.6 (default)
Under Volt. Warning 24.0 (default)
Under Volt. Warning Reco. 25.6 (default)

yes, mine does not do that, it stays at boost till turns off charge when it thinks batteries are full. And since there is 20+ amps coming in it thinks its fully charged when its really only 70-80%. I don't understand
