Re: PIP-4048MS inverter

Somewhere you mentioned that you sniffed the traffic between SCC and main controller. Is this data available anywhere? No. That method was long ago superseded by coulomb reading the disassembled code, for both the main controller and the SCC, to find out what they send to each other. Actually, for ...

Will this work with the hybrid-v series?
No. These operate very differently, so they can't use the same firmware.

If you are asking could something similar be done with the V series, I suppose that's possible, but Weber and I won''t be doing it.

Re: PIP-4048MS inverter

Progress has stalled on the firmware patches to implement a dynamic current limit. One of the reasons has been a hard drive failure on my computer.

I would imagine you can put a lower current fuse in place of the existing 80 amp fuse? Err, I suppose so, in a theoretical sense. But I'd say it would be severely frowned upon. That fuse is in your "toadstool" if you have underground power, or up on a pole if it's overhead power. And of course the ...
