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

Hi daimyo . I'm sorry that the Dynamic Load Control feature of our recent patched firmwares does not do any of those things. It only provides the serial commands that allow such things to be done by a computer connected to any one of the inverters. You would need to write the software yourself. I wo...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Someone has just popped up on the South African Power Forum claiming to know about the installation that burned, and wanting to "put the record straight" . Trouble is, he appears to be delusional. He claims: (a) there was no over-current protection, when a blade fuse is plainly visible in the before...

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

Hi daimyo . Thanks for your kind words. So maybe the best way is to wait some more time and then to install 73.00e FW? Yes. We will probably bump 73.00e from beta to release early in the new year if no one reports any problems. Do I need to turn OFF other two inverters when doing FW upgrade on one? ...

Battery is 15s 180 aH CALB

Asorbtion setting is 52.5 V
That's plenty of absorb voltage for that battery, so the limited charge current is a mystery to me.

The latest firmware can always be found via the Firmware section of the index, which is in the first post (first page) of this thread.

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.

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 inverter repairs and hardware modifications

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...

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!
