[RE-wrenches] Problems with Conext SW inverter

[Eric Smiley]

It is of grid and, yes, the generator was running when I attempted to
equalize.
Schneider has no solution and it is just outside the 2 year warranty.
I am going to try a couple of things when I go back:

   - setting the battery type to the default for FLA battery - it is set to
   Custom battery right now;
   - installing an older firmware version, to see if it is just a bug in
   the last update.

However, based on the condition of the battery, I suspect the client has
never been able to properly equalize; despite thinking they were doing
everything properly.

A real shame they even released this inverter to the market. This will
likely be the third and last CSW that we end up replacing with a Magnum.
If anyone else has had issues with the CSW, I'd like to know. We know other
installers that believe this was a defective product from the beginning and
would like to press Schneider to compensate clients and installers who have
wasted far too much time and money trying to make it work as promised.
