SmartSolar Temperature Compensation changes voltage in the wrong direction

Hi all,


i'am using a SmartSolar MPPT 100/30 with firmware 1.54 and a external ve.net temperature sensor.

When setting the temp. compensation to -30mV, on temperature below 25c, in my case 18c, the voltage is lowered from 29,4V to ~29,25V instead of 29,55V.

When setting the compensation to 30mV (plus) it works as expected.

Is this a bug?


Thanks so far


Marco

Hi Marco, just let 30mV without sign, the mppt should adapt to the needs.
