Re: PIP-4048MS and PIP-5048MS inverters

Hi mates :). My first post here, but long time reader. I must thank the topic participants for the excellent info found on it! I to have a PIP-5048MSP for about 4.5 years.

Beta Version of Patched Firmware 73.00e for some PF0.8 models (introducing KettleKomp™) This is the fifth version of our patched firmware based on factory firmware version 73.00 for the PIP-4048MS and equivalents. This patched firmware has all the same patches as 73.00d and earlier patched firmware...

Re: PIP-4048MS and PIP-5048MS inverters

We have just bumped patched firmware 73.00d from beta to release. I note that we will be posting the beta version of 73.00e (with KettleKomp™ ) in the next few hours. It seems we failed to announce when we bumped patched firmware 72.20c from beta to release three weeks ago. Sorry about that. Many th...

The electrolyte in a NiFe cell is alkaline-based potash, which is just distilled water and potassium hydroxide. This is a commonly used plant fertilizer.

Re: Preparing the grid for EVs

Hi Luke . It's great that you're doing this. But we want to be good network citizens, so if you just tell us when you'd like us to charge our EVs, there may not be any need for any network upgrades. All commercial EVs have a built-in timer that let's us plug in as soon as we come home but only charg...

Is there a patched firmware version for the Axpert VMII 5kva (PF1.0, PV 120v-450V) aka PIP5048GE
No. Sorry. We need a manufacturer's firmware update file for it before we can do that, and no one has sent us one. All available patched firmware is listed in the Firmware section of the index page.

Re: PIP-4048MS and PIP-5048MS inverters

Coulomb and I have been working on a set of firmware patches to address the "kettle cut-off" or "premature source switching" problem. We had a major setback when we bricked one of monkeytom's inverters in the process (a new one is on its way to him). But as of today, I am testing the first working n...

Re: PIP-4048MS and PIP-5048MS inverters

I have a question. If, in my PIP4048, I would replace transistors, withstand higher voltage, and load software that would allow up to 66V, everything would work properly? if I understand correctly, I could raise the charging voltage to 66V Unfortunately no. For starters, you would need to upgrade D...

Re: Cell compression?

I can't help wondering if the authors are confusing megapascals with kilopascals. The strange numbers they are using, like 1.32, suggest they were working in non-SI units. Edit: But I can't find any units that would give round numbers for pressure. Nor can I find any that would give round numbers fo...

Re: Cell compression?

I don't think anyone is in danger of overcompressing their cells. That's an insane amount of pressure. It's 14 atmospheres! For the cells in Mexy, whose broad face is approx 0.12 m x 0.18 m, it's equivalent to a weight of 3 tonnes!

Re: Weber and Coulomb's MX-5

Many thanks to Mike Van Emmerik (Coulomb) for his help on Friday. With only 14 of the 16 worst cells replaced, we did a range test and found that it had gone up from 65 km to 78 km (to turtle mode in both cases). Then we examined the data logged by the CMUs and found that the cells that had gone to ...

Still trying to get my head around what is actually causing the loss of capacity. The house battery packs I've tested recently still have over 100% of the advertised capacity, one 200Ah pack is over 7 yrs continuous service and the other over 5 yrs continuous service. The 5 yr old pack has spent qu...
