Re: Bricked or not bricked...this is the question....

All opto-couplers seem to deteriorate slightly with age, so if it was marginal then, it could well be unable to handle a firmware update now. Ordinary communications (commands and responses other than firmware updates) operate at 2400 bps, where there is four times the time for the opto-coupler out...

sunny day but 0V from PV

Hi guys. I've a little problem. I think it's an hardware problem, but I’m not so sure. I've not found solutions in the forum so I ask if you have any idea. The problem is that my Axpert 5k 0.8pf doesn’t see the PV. Icon of panels is NOT present, but I’ve a good voltage (about 105-109V) and batteries...

Re: Bricked or not bricked...this is the question....

I'm intrigued to note that the update happened at 12 blocks per second, some 20% faster than it usually happens. I wonder if that means that a normal update is usually slowed down by several retries. I'm also surprised by the crazy erase times, but that doesn't seem to be a real problem. Warning to...

Re: Bricked or not bricked...this is the question....

It looks to me from all the repeated data blocks that the data is becoming corrupted between the PC and the microcontroller in the inverter-charger. Weber and I have noticed that not all communications boards are created equal; some seem to have more trouble than other operating at 9600 bps (the sp...

Bricked or not bricked...this is the question....

Hi guys. This is my first post in this great forum and I don’t speak english well so don’t kill me if I do mistakes. I’ve a huge problem with my Axpert MKS 5k (0.8f - SolarPower24). In the past I upgraded the firmar to version 73.00c withtout any problem. Now, trying to update to 73.00e the inverter...
