Hi and welcome.
and have read almost the 60pages
my inverter is from 2016-04
i think this is my firmware (yes?):
Yes, you have firmware version 75.10.
why are you all talking about 72.40 or .60 or 70? do i have 75.10??
Interesting. Well, most of us have the single MPPT models. Yours is a D
ual MPPT model (PIP-4048 MSD
), with the 120 A of solar charging (ours are 60 A, and I think models from a few years ago had less than that). There were a few changes in 72.60 that accommodated the multiple MPPT models (there is also a triple MPPT version, and they seem to be making provision for future models as well).
I have to admit I was surprised that there weren't more changes to handle the multiple MPPTs. Now it looks like models that actually have the multiple MPPTs come with a different firmware than the single MPPT models. Now that this is mentioned, perhaps SolaMahn or another user has mentioned this already
This brings up an important point. With the patched firmware (both types), we have demonstrated a fix one major problem (the inability to charge properly) and several minor ones (many thresholds are not lithium suitable). The fact that many people are using or asking about this firmware indicates that there is a genuine need, it's not just a few isolated users having a problem due to some unusual environment or other detail. We can't keep patching more and more versions, and we're at the mercy of the manufacturer for supplying the raw materials that we need to generate the patch.
So I think it's time to get the manufacturer to incorporate the main fixes into the official firmware. Others have demonstrated that the manufacturer is willing to listen to users' needs and incorporate them into new firmware, so it's a matter of setting up communications with them to make this happen.
someone has a changelog of this one?
I've never seen a change log of the firmware. It would be good to have, and most software (firmware is software that is stored in hardware, so it's still software) have change logs.
save to go back to coulomb firmware?
No, it's almost certainly not safe to use a 72.XX based firmware (patched or not) in a machine that comes with 75.XX firmware. The first two digits are the major version numbers, which when changed usually indicates a major change with some compatibility loss. At minimum, I'd expect that you would not be able to see the two MPPTs' icons on the LCD screen. It's possible that they have a completely different LCD display, so the screen may make no sense at all.
Plus, until the manufacturer releases the 75.10 update files, it won't be possible to go back to the original software, in case there is any sort of problem. For whatever reason, it's getting harder to find these software update files.
