Guidance please EG4 6000 xp off grid set up

[Goatfarmer]

Okay guys
Stay with me lol
I'm learning as I go with my partner on our off grid homestead. (No current grid connection) We use just a generator right now but just purchased our first jump into solar.
Here's what we have so far
One Eg4 6000 xp
Two 48v 100 amp hour batteries (just a starter pack so to speak)
And we have 21 290 watt panels to work with

So the plan is a ground mounted wooden structure cause we have an abundance of lumber right now.
The string calculator says I can do two strings of 10 even with possible 32 temps here in FL.
Should I cut down to 9 to play it safe tho? as I've seen mentioned or would I be good with 10?
Next question apart from wires and my fuse box is there anything is I need for this to get going? Like an additional kill switch for the PV or is that not necessary for the AOI with no grid connection. Also have questions about grounding rods. One? Two? aWas planning on doing the extension cord method I saw in wills video as we aren't powering much right now other than small camper AC and fridge/ phone chargers and we aren't sure where our final structure will be in the years coming.
The electrical system will be housed in a shed located under the solar array.
In a small travel trailer right now with a 2000 watt generator, and building a small 150sq foot cabin. Then eventually a house. But that's later.

Anyway I appreciate if you stuck with me and greatly appreciate any information. I know I have lots to learn, finding this group has been a huge blessing for me!

Also do I need a chargeverter to use my generator to charge the batteries? And if so, could I possibly just use the chargers that came with them connected to my generator? Would I have to disconnect them completely from the inverter if so? Sorry if those are stupid questions.

The 6000XP Inverter is good for up to 480V DC on each of the MPPT inputs. Voc on those solar panels is 39.5V each. Even at 32F (0C) the voltage is only going to go up to about 420V.

One rod for the equipment ground is sufficient.

Nothing wrong with having an alternate method of charging batteries like a Chargeverter but depending on your budget I would go ahead and connect the gen to the AC Input on the Inverter and use the built in charger, its already paid for. If for some reason that doesn't work then get a stand alone charger.

EG4 recommends using generators with THD under 5%; higher THD can cause problems. Chargerverter will clean "dirty" power. So, depends on which generator you have.

You can maybe by a 240v generator that has <5%THD for what the chargeverter costs these days.

I have a nexpow yh2200i
It is an inverter generator
I cannot find an exact number for the THD percent but google says most generator inverters are like 3%?

 

[kampto]

That nepow is 120v, I think it will work to charge 6000xp if hooked up to a specific input leg. Have tried that yet so cant say.

I got this one, says 1.2% THD, havent connected to my 6000xp yet been using with other things.

You can use a 120V generator, but keep in mind that the load will be limited to 120V. The generator will have to be connected to L1-N

Thank you!

Thank you!

You would need a 30 amp capable 120v cord to use it to its fullest 28 amps.

Thank you!

I'm going to wire mine up with 6/3 romex and just so in the future, if I ever get a 240v inverter, I'm all set.
