Re: PIP-4048MS inverter

Hi Weber, Thank you and Coulomb for taking the time to investigate this bug! We note that we have already determined that your second problem—the exit from an otherwise timed absorb stage when the charge current falls to 1 amp—is not caused by any of our patches, and is not a bug, as it has the pote...

Re: PIP-4048MS inverter

What's the feeling amongst timed absorb users? That would be a very welcome change for me! I've got 4 100ah gel batteries in series. I've read somewhere that "Gelled cells should be charged at no more than the C/20 rate, or 5% of their amp-hour capacity." (http://www.electrovehicles.co.za/understan...

Re: PIP-4048MS inverter

So I can't replicate your problem. I don't understand why you seem to imply that the problem would be seen quicker with the current limit at 2 A compared to 10 A. Please see the comparison of charging at 10 amps vs charging at 2 amps below. http://sinux.ch/img/Capture5.PNG Absorb should in theory b...

Re: PIP-4048MS inverter

Sorry I forgot to reply to some of your questions : Don't go to any trouble, but perhaps you remember if it is possible to power up your inverter without the battery connected, but AC input present? No It's not possible to power my inverter without the battery connected. Is it possible that your Ras...

Re: PIP-4048MS inverter

Thanks for the kind words. I note that I didn't have much to do with finding and fixing the premature float bug. That was coulomb. But I am responsibile for the changes to current reporting that you are having a problem with. Sorry I forgot to mention Coulomb! Thanks to all! and thanks for the kind...

Re: PIP-4048MS inverter

Hi @ weber I've installed the firmware 73.00a on my inverter. Works great! Thanks for all the time spent on this! I installed it because my batteries were never fully charged with the old firmware (early exit of absorb stage). I'd like to report a bug/regression : From version 72.70c beta, you've "i...
