Hi,
After a very helpful discussion regarding a batch of panels I picked up, I picked up an EG4 6000XP. There were more affordable options but I wanted to get into the EG4 ecosystem, as I may use more of their stuff in the future. I'd appreciate a quick check on my plan to make sure I don't have any glaring errors.
This is a fully off-grid setup. I have a pile of First Solar FS-6470A-P panels that were quite cheap, so I don't mind using more than I need. I plan to wire two separate parallel strings into the EG4. The EG4 will output to an AC panel and I am only planning to use the AC output without any battery control. I have a Zendure Superbase V which will use the AC power to charge its internal batteries. I already have a pair of strings of different panels going to the Zendure's DC input that are out of scope of this question.
The FS panels in question are 470W, 2.46A, 224.3 VOC. I am not accounting for outside temperature at this time but will recalculate if my plan makes sense (I live in the Northeast so it will be very cold in the Winter).
My plan is as follows: 7 panels in a parallel string to each MPPT on the EG4. This should give a max voltage of 224.3V, wattage of 3290W and amperage of 18.27 per string which are within the limits of the EG4's spec according to the manual. The amperage is above the 17A optimal rating but well below the 25A limit.
The Zendure's max AC input is 3600W at 240V. My expectation is that since there's no communication between the EG4 and the Zendure it's no different than plugging in any other dumb appliance. Even though the EG4 could pull in a maximum of 6580W with this setup, The Zendure will pull what it pulls. I realize that I'm using far more panels than I theoretically need to, but the panels were cheap, and I want to oversize to account for the winter months where sun can be hard to come by on some days.
Does this setup make sense? My biggest concern is using the EG4 without a closed-loop battery system, but according to this page it is a supported configuration, and I believe the configuration is referred to as "PV Grid Off". I assume that any excess power taken in by the inverter will just go into some magical wormhole or something (as you can tell, I'm not very smart).
Thanks in advance!
