XW generator start question [RE-wrenches]

[Mark Edmunds]

Hi Dan, Jay 


You have the correct information Dan - the original design did need the
"run" signal, even with 2 wire units - the software upgrade we now have
will allow the system to look at the AC2 voltage to determine that the
generator is running so it can be a true 2 wire installation.

Cheers,

Mark

Jay,

Yes, the GSM is required to interface a generator to the XW, 2-wire
start or otherwise. The GSM also requires a "generator running" signal
in order to recognize a running generator and hold the 2-wire signal
"on". The GSM "run"
sensor circuit requires a 12 volt nominal (30 volts max) signal from the
generator, and requires another 2 wires between the generator and the
GSM, so for a "2-wire" start generator, actually 4 wires are required.
Xantrex has heard the complaints about this loss of a true 2-wire start
feature on the XW, and I understand that there's a software upgrade
available that will allow the GSM to recognize when there's AC line
voltage present at the AC input terminals of the inverter (AC 2 in, I
assume). This should eliminate the need for the 12 volt "run" signal
(and the extra 2 wires) from the generator to the GSM. I haven't tried
this upgrade myself. On the one installation I've worked on, I ran the
additional 2 wires, and piggy-backed off of one of the propane solenoids
for the 12 volt "run" signal. The GSM works fine this way.

I hope that helps.

| HI All,
|
| Do you need the generator start module to control a 2 wire start
| generator on the XW inverter?
