Flex ware inverter bypass slide [RE-wrenches]

[Walt Ratterman]

Just thought I would chime in here....  Walt Ratterman

I have trained and installed dozens of Outback three phase and quad
systems in Africa and other remote applications, and I tend to think
that the system where the slider turns everything off, and then requires
manual intervention to turn what you want back on, is perfect.  I tend
not to like everything being real automatic, without thought, and there
are lots of cases where we want to turn everything off, (without
bypassing the inverter and turning the inverter to load connection back
on.)

I am getting ready to install my first batch of Flexware three phase
systems in Africa as soon as the equipment gets there, and am hoping
this design is still pretty much the same.

(Chris:  can you let me know if there are any parts or pieces that
usually came in the PSDC and PSAC boxes that don't come with the
flexware?  Like TBB's, positive bus bar for the DC breakers, etc.
etc....Just want to be prepared.... when I get into the middle of
nowhere...

Thanks,

Walt

So - for you - I guess its because you prefer the "rocker" style AC 
bypass we had used on the PS2 - which I actually liked better too - but 
its just not possible to do this when you have multiple single pole 
breakers to control with the AC bypass mechanism - as in a quad 
configuration.

We went to the AC bypass slider plate configuration on all of the 
FLEXware systems to make them more consistent to wire up... previously 
the wiring on the PS2 was very different than the PS4 wiring...  

I also don't understand then why anyone would like the MIDNITE slider 
plate - it doesn't even allow you to read any of the ON / OFF labeling  
or the amperage markings on the breakers!  Its hole for the handle is 
extremely tight and covers up the entire front of the breaker's face.  

I also strongly disagree with the use of two separate bypasses for AC L1

and AC L2 when a dual inverter system is installed - this allows you to 
bypass one leg of AC while the other is still on the inverter.  This 
will fry 240VAC motors and possibly fry common neutral branch circuits -

resulting in a fire hazard.  Its simply not a safe and compliant design.

 

Any other opinions out there?  

Do you think it is OK to not be able to turn off the AC bypass breaker?



Do you think having two separate bypasses when two inverters are stacked

is acceptable?  

Tell me what you think - I'll be here all night if needed...

This is gonna get exciting I think...
