Hi i have some doubts about the voltages points of my midnite...
i didn't find nothing on manual on how to see the target voltages already temperature compensated..
but from what i read here in some posts its possible to see it in lcd...

I'm do all my monitoring remotely trough  MODbus, in the modbus register i can't see any register with this target voltages temperature compensated.

Question how to check the target voltage temperature compensated in the lcd and how to read it from modbus ?

thanks

The classic output voltage when at absorb or float is the temp compensated setpoint voltage, as the classic measures it. Its already compensated. Thats why it reads different from the setpoint.

I havent heard about any place to see the setpoints translated to current temp levels. But you could work it out easy enough by adding the 5mV per C diff from 25C.

Register ADDRESS    4243  holds the present temp comp'd battery regulation set point voltage.

(VbattRegSetPTmpComp)    That's, register 4244   or address  4243   and includes the
decimal 10th in there as well.

In the MNGP, the   CHARGE----T-Comp----VIEW menu shows this value.

Thanks a million bob ...
Is the register new or always had been there ?
Now I have a easy way to check the target vs the real when changing from bulk to absorb and float.

Best regards

It has always been in there I think.   In fact, it would probably have been just so that we could debug things properly.

It's quite an important number to be able to see I think.
