Mine looks to be newer.i purchased my system oct 2024.
Btw does anyone know what size battery lugs fit on this inverter? I am trying to buy some premade wires to connect my breaker to inverter.
Thanks

You can fit 2/0 lugs. 5/16ths.

They emailed me the firmware in January 2025. Maybe you have the newer hardware (can operate parallel, ASP) ? I have the previous model (ASF)
If this is a clone of the SRNE ASP 10kw inverter, I was able to fit 4/0 gauge 5/16 lug battery cables on mine. It required removing the plastic inserts from the inverter's battery cable inlets, but it does fit.

A few weeks ago, before I upgraded the firmware, I had observed a situation where the SGP briefly switched to pass-through while the load was low (30% perhaps? Too lazy to look it up) and SOC was high over 70%.
I did not understand it and the explanations on this forum (load spike) did not apply, and even if they had applied, they made no sense.
Today something else happened. I was charging the EV with 30A instead of the regular 15A, which means the AIO is already at 75% right from the beginning.
Had turned off the hot tub first, of course.
I was watching on SA how we were at 8500W. Suddenly it's 9500W (wife did use hair dryer?) ..and leg 1 was pulling 5400W.
Leg 2 around 4100W.
I thought that each leg had a hard 41A (5000W) limit?
She used the hair dryer for 5 minutes until I ran out and disconnected the EV (easier than turning off her hair dryer)
I continued to charge the EV with 15A then.

That's interesting. I can't think of any reason.
There is a surge / overload rating.
Did it go to bypass?

No, it did not. Grid input was available though.
I think 5400W was just below 110% and from the graph, it was just about 5 minutes, from 10:22 to 10:27.
Wait, it looks like she stopped the blow dryer at 10:24 for a few seconds. So, it was definitely under 5 minutes.
How can I see if an error was reported using SA? I cannot go to the physical unit right now.

That's still a nice cushion. I've never pushed my ASF or ASP's that far. Thanks for testing it.
I don't believe you can. I've never found a way, if it's possible.

We know that the inverter's output limit is 10kW.
How do we know that the limit per leg is 5kW?
I believe there are some brands/ models that offer e.g.12kW total but each leg is NOT limited to 6kW.
I went to the unit a few hours after the event and there is no fault code or anything visible on it.

It's essentially 2 5kW units in the same box, bypass is rated for 7.5kW per leg.
There are, I don't quite understand how they work when they are high frequency.
Thanks for checking.

Excellent explanation, so easy. Appreciated.

Well hell, got a bit too complacent and didn't watch for wind....
Probably a total loss I suspect...won't know till I can test/check it in the sunshine....snow expected tonight.
- $500 arrrrgh!

Guess the moral of the story is to do a sturdy install eh...

....AND.....GRID IS DOWN! For the first time since I got this system going something like 1.5 years ago... I get to use it for REAL! LOL!
All is working pretty much as expected. Furnace, Internet, Office, Computers, refrigerator .. kitchen .. TV/Radio/Living Room... NICE!!!
Also got to go around with a lamp and plug in to various outlets... Pretty much the west side of house is good on PV/Battery Power...East Side is off due to grid connection...also bathrooms off...maybe should address that in the future
and all with my one shattered panel....

one thing that doesn't work which I'd like to work is my Ring Security Camera on the front of the house.

That seems to be the case here, but we're a bit overcast so hard to say, but I have my panels in two sets of four each and they are both putting out about the same power and about right for the overcast...
