Image uploading problem fixed

We have just fixed a long-standing problem where registered users could not upload images (or any kind of attachment) to any forums except the For Sale/Wanted forum and those in the Production EV category, unless they happened to be Administrators, Moderators or AEVA members. So, for those of you wh...

I have taken photos of the unit but still need to figure out how to post them (will do once I figure it out).
Just drag and drop them into your post, then scroll down and click the Place inline button.

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

We have just bumped patched firmware 73.00e (the first with kettle compensation) from beta to release.

Many thanks to all who tested the beta version.

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...

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.

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.

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.
