Updating to Solar Charge Controller MPPT 150-100 rev2 SMART v1.58_A059.dup causes MPPT to oscillate between 0 and max power (currently 800watts) over several seconds. Can you email me v1.56 please. This installation has worked perfectly for some years, but this firmware update instantly broke it.
Further to the above, I can change the Max Battery charge rate to about 43Amps successfully. Beyond that, it oscillates, providing little charge to the batteries. That is far less than the 100Amps spec.
I have also this problems on this version Max 24A can load
Normally a have 60-70A
We need the old version 1.57 .
have this Firmware anybody ? And can send this please
Dear all, thank you for reporting this.
We're investigating this with top priority. It seems incidental (only affecting some systems/units) and happening only when the system's PV open circuit voltage is around or below 70VDC.
Just now we have put the previous version (v1.56) back on to Victron Professional. And also removed v1.58.
To revert to v1.56, login to Victron Professional at https://professional.victronenergy.com, there download the file.
And then you can install it using either the Remote firmware update feature in the VRM Portal, or using VictronConnect. Manuals:
All the best, Matthijs
Ps. for any co-readers: so far, v1.58 was only installed and available on a limited scale. It has only been available on VicProf, Dropbox and VRM Remote Firmware updates. It has not been available through official versions of VictronConnect. And only shortly during the beta version of it a while ago.
