[RE-wrenches] Problems with Conext SW inverter

Tue Feb 4 17:33:09 EST 2020

No problems that I know of and about 15 that work fine. I only use the
XW for my clients but many out there. 

You said the voltage decreased
below absorb when you tried, EQ will not start unless it has gone thru
absorb to float. 

The work around to start EQ without going thru the cycle
is to program a bulk, absorb, and float for the EQ voltage. 

Other ways
also like shortening absorb time to one minute.  

You also know that you
should never EQ a battery that is not charged without monitoring bat temp
and being on site.  

EQ does have to be enabled in set-up BTW. It is not
the firmware either unless it was a botched update. 

Do not forget to
reprogram any changes you make! Good Luck!

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.

an off grid system? If so, the generator needs to be running to execute EQ
on the inverter.

 Thank you,   Maverick

    I recently discovered a critical problem with a
client's SW inverter and I want to know if others have encountered this.
It's an SW4024 with Flooded Lead Acid batteries. The system is configured
using the Custom Battery setting: Bulk and Absorption are set to 29.2 V.
Equalize is set to 32 V. The problem is when Equalize is enabled, the
system goes through Bulk and Absorption just fine. However, when it
switches to Equalize it doesn't actually equalize. What I observed was the
voltage actually decreased to 0.5 V below the Absorption Voltage setting.
