Victron Mppt 100/20 Load output not stable?

Hi,

A question for the experts. I charge a 24V gel battery during the day via a Victron MPPT 100/20 and convert it back to mains power at night via an inverter.


I use the load output with the custom algorithm to switch an external relay.

Actually, the discharge of the battery should be interrupted at 24.6V. But that doesn't always work. Sometimes the load output is only interrupted below 24.6V. Tonight, for example, it was only at 23.7V.


How can this be?

Why doesn't it switch reliably?


That's what I don't understand.


Thanks

Might need a real load.

Have you tried the TX port method (see 5.2.4 in the manual)

What do you mean?


No, I have not tried TX. Doesn't mean anything to me
