Hi Bob
Is there any inherent advantage or disadvantage to non transformer inverters?

Tump,
I have a system exactly like this one and had similar AGS issues.
Once we ruled out conflicts between the internal Aux commands and
the AGS menu in the Mate,
we eventually figured out it was heat related. We were using the top
inverter on one of the quad
Quite a few of my friends and clients are involved in this disaster, now
the largest fire in California history. I told many of them of what they
can do to clean the air in their space. I hope this is useful to Wrenches!
Home Depot has the US made (metal case) Lasco box fan. If you tape a MRVE
I know its not the same equipment, but we recently had a Magnum
autostart doing strange things, and it turns out we had it set up for
the wrong generator configuration. With all the different types of
starting configurations on all the different generators, strange things
can happen.
We're
Hello Tump
You may want to go into the aux setpoints on the inverter being used to signal
a gen run condition and check to see
how it is programmed. It could be that the aux is being instructed to turn on
by the aux setpoints as set in the inverter.
If AGS tells it to turn on great but if inside
This is all great advice.
Remember that long wires can radiate RF. PV lines and the array can
make a good antenna for RFI as well as the battery lines.
I agree with Dave that both of those inverters are more than likely
similar. I know that the XW has a good filter on the battery line
My advice is it is more about the installation and the distance from the
inverter, and it's devices from the station location, than the make of
equipment. There are other things also that I do to fix noise and
interference. My wife is an extra class operator and several clients have
visited to
Mac,
As a ham radio operator, renewable energy installer and off-grid
system owner I can say that your customer is going to experience RFI
with most any inverter.
If you or he have no luck finding that ideal inverter I suggest
investigating the RFI mitigation
Hi Wrenches,
I have a HAM radio enthusiast that needs to replace their off-grid
inverter. He would like the inverter that puts off the least
interference. I don't know a whole lot about evaluating an inverter for
this, but I am reaching out for recommendations. Needing ~8kVa at 48V.
Thanks!
Answers to your questions/comments:
1. The same voltage in the panelboard would also apply to the junction box
in which it would be located (as suggested by Enphase). You have to bring a
240V 3-wire circuit to the Envoy in its enclosure. I don't see the
difference.
2. Enphase's IQ combiner is
I have a client w/ 8 stack of older VFX3648s, Off Grid. Presently connected to
a Mate 3 & older hub 10. The generator run time/shut down time is never the
same, sometimes 10+ hours of running while the inverters in “silent” mode. Gen
stays running despite full batteries, confirmed by battery
Jason:
Several issues come to mind:
1. I think the question that dictates is the insulation rating of the
Envoy and associated wiring as possibly exposed to voltages within the
panelboard. This is akin, but not identical, to the scenario described in
NEC 300.3(C). Insulation rating
