How to protect 24v battery bank from low voltage

[ice2484]

I was wanting to make sure battery voltage does not get to low on 24v battery bank.

Would this be a good product to use with 24v 1500 watt power inverter

You tell us. 23.6 volts on a resting 24 volt battery is less than 0% SOC. You normally do not want to go below 50% which is 24.48 volts. So you tell us if that is what you want.

Power inverter cuts off at 21v. Try to cut it off sooner without
destroying batteries.

I think one of these may be more appropriate, since they have a selection of higher voltage disconnects than your inverter, which is typically too low:

12 / 24v autodetect, and you choose the amperage you need.

The highest cutoff voltage for the first BG model on that page is 12V. A bit low for stopping at 50%.
Maybe some of the other models have higher voltage cutoff options? Read the manual, not just the specifications.

I agree but we have a difference in operations.

For me, an LVD isn't used as a catch for 50% DOD, but is a last-ditch effort to stop a runaway load or forgetful operator from going too far before causing major damage. 12v in this case is better than the typical 10.7v you see on some inverters.

What should be done if you hit the lvd is to modify your monitoring, conserve power, or switch to a larger capacity battery. Not good for the battery, but serves as a handy reminder to fix the issue at hand when one does bang up against the lvd, otherwise it will start to cost you.
