[RE-wrenches] UL3741 inverter listing for residential roofs

[jay via RE-wrenches]

HI All,

I”m wondering if there are any rack companies that have a listed product for 
residential roofs?

The only inverters I’ve found have been for larger commercial size.  

Living in an area with lots of flat roofs, ( OK super low slope) it would be an 
option vs micro or other power electronics

thanks in advance

jay

Hi Jay,

Ironridge XR is 3741 listed, but only with Tesla MCIs (for now), I believe.

Best,
Blake

[RE-wrenches] Sol Ark 12 k PV monitoring

[William Miller via RE-wrenches]

Friends:



I have been through the manual and I can’t find anywhere where you can see
on the inverter front panel the PV volts or amps for each of the MPPT
inputs.  Am I missing something?



Thanks,



William Miller

[RE-wrenches] Neutral run to critical loads sub-panel

[William Miller via RE-wrenches]

Friends:



I found a grid-tie battery-backup system with a 120/240 VAC critical loads
sub-panel that has no neutral run to it.  All of the 120 VAC loads have
their neutrals land in the meter panel.



I have always felt instinctively that the neutrals should land in the
breaker panel that feeds the circuit.  I have looked through the NEC to
find a passage that spells this out but I can seem to find one.



Is this a code requirement?  Is this recommended practice?



Thanks in advance.

Re: [RE-wrenches] Sol Ark 12 k PV monitoring

[William Miller via RE-wrenches]

MD Electric:



I touched the screen and it did not respond.  Could the display be
defective?



This unit is a 12K-P.  The serial number is blank.  I am not sure I am
looking at a manual for the 12K-P.  The Sol-Arc website shows only the
12k-2P.  Are there differences in the operation of the P versus the 2P?



Thank you for your time.

Re: [RE-wrenches] Sol Ark 12 k PV monitoring

[William Miller via RE-wrenches]

Michael:



This is my first experience with a Sol-Arc and I did not install it.  I
touched the screen gently and then less gently. There was no response.  I
could only navigate by using the arrow keys.



I see now there is a frozen touch screen recovery procedure.  It involves
pressing the Esc button for 7-10 seconds.  I will try that.
