EG4 6500EX-48 "HELP"

[David Mitchal]

I have an EG4 6500-48 Inverter/Charger that I need to connect to the Grid for A/C IN. The manual suggests #4 wire, but how do I connect #4 wires to the Main A/C Panel and what size breaker do I need for 120v system??? What am I missing? And please keep it simple.
HELP!!!
Thanks,
David

I have an EG4 6000 and am using 60 amp double pole breakers in a sub panel right beside my inverters. POwer is fed from my main panel to this sub panel and then to the inverters. If you are operating only as 120 volt, you may only need a single pole breaker and your manual should inform you as to the amp rating. Just be sure that you are not trying to back fed a panel with your inverter output that has the AC input to your inverter.

The 6500EX-48 has a built-in breaker at the a/c IN but how do I get 120v from the Main Grid panel using #4 wire? Do I need a single pole 60amp breaker and that's it?
Thanks

I'm sure you have seen this, but this is how I started my journey.

 

[David Mitchal]

Been there numerous times, no help, thanks anyway.
Nowhere in the manual does it say anything about the connection of A/C IN other than the wire size. Not one word about breaker size.

That's not completely true. While the manual doesn't specifically use the word "breaker". Page 42, specifications lists the MAX input current as 60A. Then at the end of the manual there is a certification that indicates the max output current is 54.2A.

 

[David Mitchal]

Found it! It is on page 6 of my manual.
There is limited info on the Eg4LL V2 Batteries.

I am using (2) 60A single pole breakers. (1) for each of my two 6500EX units.

The units will throttle to 60A max if bypass demand + charging demand >= 60A.

It will remove battery charging amps as bypass amp need increases. You might see a sligjt voltage dip when this happens. I tested mine at max and my voltage usually rock stable at 117V dipped to 113V when it hut the throttle.

EDITED: I've made this my build thread, so while there is an OP question below if you keep reading I'm slowly posting updates of my entire system. Mods please feel free to move if desired. System summary: (2) EG4 6500s for 120/240V config. (40) Hyundai 390W panels in 10s4p to stay under 500VDC...

Thanks! Where did you find single pole 60 amp breakers for Homeline Load Center that uses Square D push in breakers?
I have not been able to find them anywhere.

I have QO breakers, but Siemens makes a single pile 60A in the homeline style

Siemens 60 Amp Single-Pole Type QP Circuit Breaker Q160 - The Home Depot

Siemens offers a wide array of thermal-magnetic circuit breakers that are the key element for overload and short-circuit protection of your home's electrical system. To provide additional protection Siemens

[David Mitchal]

That would be it!
Awesome, thank you

 

[David Mitchal]

I didn't think a Siemens breaker would work in a Homeline Load Center.

 

[PreppenWolf]

Poking around it seems they do fit but are not UL listed as a direct replacement. I don't see a Homeline 60A single pole. You might have to buy a two pole breaker and only use one pole?

 

[David Mitchal]

Yeah, thanks, that is the only option I could come up with also. Do you think using the square D two pole would be safer than the single pole Siemens?

 

[PreppenWolf]

I would say yes, but only because I have no experience with the Homline style breakers and I know there are a lot of "it's close" style breaker boxes.

Great response,
Double pole it is ?

I'm facing the same thing, I have a 6500EX and a 60 amp double pole breaker and am wondering if it is ok to use 1 pole to run my a 120v load center.

Would anyone know, and am wondering if that's what David did and how it turned out?

 

[BentleyJ]

Electrically a double pole breaker is no different than 2 single pole breakers installed next to each other. You would be able to use only 1 pole of the breaker safely.

Mechanically the poles are tied together so both will trip even if the problem is only present on one leg. The mechanical link is either accomplished by an externally handle tie or internally and in that case there would only be one handle.

Thank you BentleyJ I appreciate the help!
