Re: [RE-wrenches] Low Frequency transformer off-grid inverter options

[Kienan Maxfield via RE-wrenches]

Mac,

Victron would work quite well as well. The biggest drawback is that they don't 
have a single unit for 120/240, but stacking two units works great and they 
have been really good for surge capacity in my opinion.

I admit that I am biased. I've been using Victron for 6 years, and 3 years ago. 
About 3 years ago, I switched away from Outback and Schneider and started 
primarily using Victron. When I did, my equipment failure rate plummeted. In my 
own experience, Victron has been significantly more reliable, so I've become a 
real Victron advocate. Obviously, the other brands do have some advantages. 
Outback's online platform (optics RE) is the best for making it easy to adjust 
settings remotely from any device like your phone. Contact me off-list if you 
are interested in Victron, and I'll give you a lot more info about Victron.

Thanks,
Kienan Maxfield

Fully appreciate everyone's input.

The Midnite Rosie sounds interesting for sure.  Midnite is a great company with 
great support.  Smart people answer the phone and that really counts for a lot.

How are you getting your hands on these?  I can't seem to find much info, no 
spec sheets etc.  None of my vendors have them and Midnite is estimating Apr 
2023 as the release date.

I also have a Midnite Solar Rosey, both are connected to the same battery so 
it's an equal comparison. The Rosy inverter will surge right through and finish 
the job, the XW is not in  the same league when comparing surge capability.

 A bonus is that the Rosey is really quiet as it does not have that big heavy 
transformer making noise under heavy load. It is easy to install as it is not 
as heavy. So far it's a game changer in regards to inverter hardware that I 
have tested.

Happy to hear that ! When it is on the market and gets reviewed and 
tested for split phase balance, surge, and has a networked/monitored all 
in one power system it will be great.


Costing, a 10 year warranty and training also.

worse lately (could be a load issue), brown outs, dimming etc


He wants to upgrade the system, get remote monitoring etc.  I tried a 
test with a Sol-Ark 12, and it won't start these large motor loads.  I 
was a little surprised by that but I know they aren't as good as the 
low freq transformer based inverters at these surges.


I confirmed that its not just an overload from imbalance because the 
240V loads will also overload it.  I got an inrush measurement of 48.5A 
Ac @240 (but it didn't start the load before Sol-Ark would shut off)


What are my options?
Schneider XW Pro 6848
Outback Radian 8048 (Is this a low freq device?)
Sunny Islands are beasts but weird to work with and not user friendly

Any others I should consider?  He does have some significant 120 only 
loads so I don't think the Outback vfxr are a good choice.


Is it as simple as saying if the Magnum can start this load, the Radian 
should?


I appreciate your input!

Hello i have an XW Pro that starts a 2 HP induction motor reliably, i

Fully appreciate everyone's input.

The Midnite Rosie sounds interesting for sure.  Midnite is a great company
with great support.  Smart people answer the phone and that really counts
for a lot.

How are you getting your hands on these?  I can't seem to find much info,
no spec sheets etc.  None of my vendors have them and Midnite is estimating
Apr 2023 as the release date.

Re: [RE-wrenches] Low Frequency transformer off-grid inverter options

[William Bryce via RE-wrenches]

I run the XW6848 in my shop. When running my CNC plasma table the XW will
shutdown due to exceeding its output rating if it is a long cut on metal
when the 4HP compressor kicks on.
I also have a Midnite Solar Rosey, both are connected to the same battery
so it's an equal comparison. The Rosy inverter will surge right through and
finish the job, the XW is not in  the same league when comparing surge
capability.

 A bonus is that the Rosey is really quiet as it does not have that big
heavy transformer making noise under heavy load. It is easy to install as
it is not as heavy. So far it's a game changer in regards to inverter
hardware that I have tested.

Re: [RE-wrenches] Low Frequency transformer off-grid inverter options

[Chris Sparadeo via RE-wrenches]

I have a client with a large woodworking shop…cabinet table saw, large 20”
240V bench planer, chop saws, compressors and a vacuum system. A single Sol
Ark 15K takes care of these loads flawlessly. It seems that that inductive
load snag with the smaller models has been resolved with the 15K.

Best,

Hi Mac

The radian is low voltage transformer
Based. Has hella surge capacity 

I would consider what web based monitoring system he wants and go with that 
platform. 

Regardless of system I’d install soft start/vfd on the larger units. Just 
easier on everything.

The solark 12 doesn’t seem to be good for larger loads and doesn’t do out of 
balance well, and limited to 6kw per phase. The new 15 might be better, not 
sure. Numerous YouTube videos showing side by side vs XW and radian. Both run 
stuff over their rating which the SolA won’t run even though its under its

Re: [RE-wrenches] Low Frequency transformer off-grid inverter options

[bzp via RE-wrenches]

Larry.


Hera's an idea. Put a 1:1 isolation transformer of suitable power rating 
between the inverter and load. The iron core will act as a energy 
storage element allowing for a cleaner ac waveform during start.

Hello Wrenches,

I have a new client that has ran a pretty decent wood shop for
about 10 years on a Magnum 4448.  He's got some large loads,
planers, saws, compressors vacuums etc.  They are really nice,
heavy duty pieces of equipment.  Amazingly, the Magnum has been
able to start these loads for the most part for 10 years, but he
has reported that it has gotten worse lately (could be a load
issue), brown outs, dimming etc

He wants to upgrade the system, get remote monitoring etc.  I
tried a test with a Sol-Ark 12, and it won't start these large
motor loads.  I was a little surprised by that but I know they
aren't as good as the low freq transformer based inverters at
these surges.

I confirmed that its not just an overload from imbalance because
the 240V loads will also overload it.  I got an inrush measurement
of 48.5A Ac @240 (but it didn't start the load before Sol-Ark
would shut off)

What are my options?
Schneider XW Pro 6848
Outback Radian 8048 (Is this a low freq device?)
Sunny Islands are beasts but weird to work with and not user friendly

Any others I should consider?  He does have some significant 120
only loads so I don't think the Outback vfxr are a good choice.

Is it as simple as saying if the Magnum can start this load, the
Radian should?

I appreciate your input!
