EG4 6000XP PV connection

[bigbass57]

I am running 5 - EG4 6000XP inverters. I have 30 - 395W bifacial panels. According to the EG4 panel sizing calculator I can have 11 panel per MPPT 1 string each meaning I can have 22 of my 30 panels connected to the first inverter. My question is do I have to have panels connected to each inverter or can I hook them up to the first and second inverters only with no panels on 3-5? Thx

I would put some on each inverter. That will give you massive surge power when the sun is shining.
It is generally said to "have more" on your master inverter. With that said, every time you turn the inverters off, it seems to designate a master. I guess this is the order of turn on so easily mitigated.

As for 11 panels, I wouldnt.

You need to run the cold weather calculations for your area.
Im in Wi, and I can only have 9 370 watt panels with my max low temp of -21F

Cold raises voltage. It is recommended to have a buffer.

Current wiring I have 7 panels on the first 4 inverters MPPT #1 nothing on #2 with no panels on the 5th inverter. I do have more panels coming in the future. I did the EG4 calculator with my lows reaching -15 and my highs at 114 degrees. This is where I got the 11 panel number. I attached the report from the calculation. Of course my main concern was whether or not to have panels connected to each inverter. Thx

Do 10, Sleep well
Trust no one.

Speaking of, 10 is an even number. If your situation ever changes, like shade in the winter, you can easily divide the string into 2 new strings and help out shading issues.

I mention this because I ran into this problem with my string of 9.
I cant divide in half!

I like that idea. My thought was to do 10 per inverter once I receive more panels. One good thing for me is I do not have shade.

I'll vouch for that. I've seen peak spikes of 5600w on a 4Kw array here in Canada on -20c days

Wow!!
