MPPT 75/15 Smart Charger does not cut off load when reaching low level set

Hello


My MPPT 75/15 Smart Charger does not cut off load when reaching low level set.

Why could this be?

I've activated user defined Algo 1 and se 25.00 V and 28V but not cutted even 24.8 reached...

Any hints?

FW: V1.46 and V2.23 Bootoader V1.10

Have you tired 'always off' to see if the load output turns off under that?

I've now noticed that even no load connected 0.2A is displayed at load output.

Setting alyways off solved the wrong display and connecting a load, load is turned off.

Setting always on works too.

Now I will test with values... Will post if it works...

Did still not work.

Now I've compared all values from an other one I have 100/15 charger and this one has

Rx port function: "Load output configuration" as default

where new one had other one, I don't remember which one :-(

I think it was "Load output on/off normal"!!

I have not set this value on the other one, so this seems to differ from this 2 models

or old fw version....

Where are the infos about this configurations?


I've also removed the jumper is on the VE.Direct connector as mentioned in an other post.

And yes de delay is exactly 2min after reaching the state to power off or on.

I thought the delay was if you change the configuration, but it is applied everytime a state change is reached...
