Hello Dave,
Be sure you calibrate the flexnet and the inverter voltage. My gut feeling
is that the Delta voltage you have is too tight. If you have the system on
Optics, I'd set the LBCO pretty low, then observe how much voltage sag (or
where your voltage cliff is) you are getting at the dischar

I am using Flextime here so that we are only using Grid Zero mode from
2-6am, when there is no solar coming in. The rest of the time, the system
is in Grid tied mode so that we can take advantage of as much solar as
possible. But the battery bank is two strings of the NSB190 FT Bl
I agree with John also. one of the better-performing off-grid houses I
worked on used a 48 to 12-V Samlex converter. The 12-volt thick-walled
refrigerator was about 4 amps at 12 volts. The lights, radio, and small TV
drew very few amps each/ I also used an Outback 3648 inverter, which the

Hi all.
Anyone know what the tare loss and efficiency is of a 75 kw transformer?
And it would be run mostly at 1-10kw max.
This one specifically.

I’m just curious about it. The situation is 240vac grid at the street, 600’ to
the house 400 amps.
Why 400 amps on a house w
Hi Jay I have gotten this type of information directly from Hammond, I
would think from transformer to House line loss should be considered. From
my Experiance, people go to 400 amp services mostly for circuit count. I
have measured a few transformers in past but I don't know where data is
now.
Do you know the transformer impedance?

Should be easy enough to look up on the manufacturer’s website.

I have a new client wanting to upgrade an old system with DR inverter, 4
golf cart batteries Trace C40 CC and two small PV panels. The system was
definitely installed by a professional with breakers and switched and I am
looking at the photo the customer emailed to me and other than upsizing the

John; I had quite a few Trace DR series in the field back in the day, but
only one left alive today, fortunately in my guest cabin and not at a
client's house. They had a pretty OK waveform for a modified square wave
inverter, but some modern appliances were just a no-go with a DR, including
some m
