Not much any more.. Manual says: recommended spec of AC breaker is 40A for SPF 3500 ES and 50A for SPF 5000 ES. I have a pending order for 32A, its to less? Pink

I have placed a order of breakers on aliexpress but they estimate 2 months delivery... thats forever to wait.. I ordered TOMZN ac and dc breakers who from my research should be in the sweet spot of great value, fair quality to fair price. Any ideas for some faster solution of good mid prized breakers? Aliexpress order can be canceled) Pink

Looks good if you want on grid too.. and price good too.. I just completed my 2 x Growatt SPF5000ES order with WIFI and Thailand Special Line delivery for 54k B . So now just wait for the delivery. And hope for the best. Pink

Yes. im tempted... im back and forward now on this Growatt deal and the Mpp Max 11kw. I guess its quite a few more Growatt here in Thailand.. So maybe future service and parts easier? Pink

I posted "Thailand Special Line" to the seller today and got a offer back: 2 x GROWAT SPF5000ES $595 EACH Shipping cost:236USD ship by Thailand Special Line including custom declearance and tax. Pink

What i see from the video he eliminated the Inverters ac inn fully so the ats used direct grid when no solar and no battery. I wanted to switch grid between inverter AC Inn and Main breaker box. Then when grid goes to main breaker box, inverter AC Out must close. Pink

That's why i was looking for a switch solution who close inverter ac out in same time as grid power switched. A remember solution for sure i will not get. Pink

If you for now ignore the ATS: If breaker box get power from grid. And inverter AC OUT is connected to Breaker box,, i guess would be a issue. In short it means AC Out got grid power. Pink

Im worried about the Inverters AC Out not ac In.. If ac out connected to breaker box for serving the load when grid routed direct to breaker box, then inverter will get power from ac In. Pink

Ok thanks for the info. I had the idea that i would make a easy way to re- route the grid back to main breaker box if need to disable grid from inverter. Then i come to think about inverter ac out would get back feed power from the breaker box grid. Now I'm thinking maybe skip that's part just connect all direct, then if need to switch back only move grid wires from Inverter breaker to breaker box again. Pink

I see there is a larger ATS with 4 ports on each side Could i use 2 for main grid ( beakers and inverter) and 2 for inverter ac out ( breaker box and none) So inverter ac out is off when grid is routed to breaker box? Pink

Yes i know, but could be an idea to longer life on the inverter to give it some rest? Regarding the main grid switch to either main breaker box or to inverter as we discuss before i guess i like the look and feel of the ats (in manual mode) better than the knife switch. Pink

Here is a setup with ats used with hybrid inverter Pink

Crossy. I asked a seller about the Special line and give link to Evereast, but i see also another link in your post to http://www.1express.net/index.html# Both correct for this special line service? Pink

Back on Inverter search. What i found today is MPP might sold out on the max11kw. I still looking around, and also noticed that Powmr have better reviews than MPPsolar on Amazon... Pink

After i see this video about MC4 Connectors i got worried about mixing connectors from different brands. Ex the connector on solar panel could end up to be different from what buy for cables to inverter. What's your view and experience on this? Pink

How is your panels taking very strong wind? I might expose my first row if panels for some more air than others for less shadowing. Pink

Here is a simple drawing of my plan for the one side of my roof. If any better idea for how to connect the 7+7 panels feel free to suggest Pink

Im looking for some easy online tool or template to show my panel setup, any ideas? Pink

What is the other options? Do you use any switch between grid and inverter vs breakers? Pink

Good point, check my update on the knife type switch Pink

How much usable average wh per month could i expect from 6600w panels? Could i calculate from your numbers, or your different setup will make it different? Battery limits not counted for now. Expect unlimited capacity for estimate Pink

Maybe i should use this one if back feeding is a issue: If i use 2 in for grid and 1 in for ac out (inverter) then ac out power cut together with grid cut from inverter. Pink

I have plan to use a Dual Power Transfer Switch between my grid line to inverter and direct to house breakers so if any issues with inverter I can easy change grid to go off or direct to house breakers. One think have bother my main: If grid is switch to house breakers and if not ac out on inverter is disconnected first from house breakers then will the inverter be back feed with grid power? I guess that's not wanted. I do have plan for breaker on ac out to.. Pink

Thanks, i guess im a bit low on my 20 x 330 (6600kw) to expect 800kw+ month. I might ad some more kw to my plan. Pink
