Wrenches,<br>
I have a customer that is reading voltage with a
non-RMS meter in the following scenario: 4000 watt Onan RV
generator (older) at ~5500 foot elevation...its output is connected
to the "AC in leg 1" of an OB VFX3648 using (customer installed, I
came on this job after-the-fact) 10 gauge running about 75'. Genny
fires up, feeds AC IN in VFX, sends about 1.7 KW to the batts, while
also running moderate loads in house <i>another</i> 75' away, again
through 10 gauge. <br>
<br>
She is complaining about the voltage reading ~95 volts
at times in the house. Voltage at genny is still around 120 (I am
told) I suggest up sizing wire to 6 gauge, which they do but voltage
is still in the 105 V range in the house, same scenario. As the
batts come up to charge and input tapers, voltage also comes up
some. Shouldn't the voltages be read with an RMS type meter to be
accurate? She thinks the inverter is not working right though I've
tried to explain to her that in standby the inverter is not
inverting, its just passing genny power through, unchanged other
than the load its pulling to charge the batts.<br>
<br>
Other insights to voltage drop in this case other than
an RMS meter? Does it matter if the last loads are seeing just 105
volts?<br>
<br>
Thanks,<br>
Bill<br>
