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
I know it is an old thread, but I am seeing the exact same thing with my smart solar 100/40 ver 1.61 (latest version), but it does not seemed to have been answered here. I posted my question/experience here: https://community.victronenergy.com/questions/225175/smart-solar-mppt-temperature-compensation-flipped.html
Hopefully there will be someone answering any of these.
pushing the bug up again
Hi Marco, just let 30mV without sign, the mppt should adapt to the needs.
Michel
but how can that be the solution if is simply wrong. this leads into damaged batteries and must be fixed!
hello!
did anyone can give a proper answer for this issue?
Anyone from Victron will ever respond this?
Hi all,
Indeed, nothing has changed in terms of temperature compensation, despite the new FW ver. 1.63.
I have checked it thoroughly this time. As somebody stated before, put the numbers without "-" sign.
I believe it works well with "-" sign in case you have remote BVM device installed, but I do not need it in my application.
More important is how you set other critical parameters in your system.
