Shipping Container System Up and Running

Super Beginner here, I took my first steps over the past 4-5 months putting together a small system; 4000 watts of panels on the roof of a shipping container, two Growatt Inverters (only one in use - the second is for expanding the system), and two EG4 batteries.

Now it's time to understand the nuances of the system...


Reading the data on the inverter at 1 pm today; with a super clear sunny sky, 94 degrees, I get a reading of 13.6 +/- Kwh from the panels and 219 volts.
Is this good power production for used panels, which are 400 watts each (10 panels) and 48 open circuit volts each?

Thanks in advance

Thanks copec... Does the reading I'm seeing 13.6kw/h mean that at that rate of charge, in one hour it will produce 13.6kw/h's?
 
Great minds think alike! Shipping containers and solar go together perfectly.
Your setup looks awesome!

I’m currently trying to get my bms to communicate growatt has terrible manuals

Man... Thanks... Yeah, the shipping container project is fun... A bit of a challenge keeping a big metal box cool, but it's working out.
Good wishes with your bms communication challenge!

Trust me I’m dealing with that now. I just insulted and framed this 12x8 room in the 45’ box. Huge difference in temperature.
What are you doing with your box?

The back half of 40' is storage, and garden supplies, and the front is a small studio apt for when my kid visits.

Looks good.

Nah, it means that it has collected 13.6kw/h so far that day.
