Howdy y'all!
Can't tell you what a great resource this has been, between the forum itself, watching Will's videos, etc... Great community and super happy to be here.
Here's what I've got put together (ordered) so far:
- 16s 100ah fortune (Overkill) batteries (48v)
- Overkill 16s BMS
- 2s3p (6) Hanwha 425w 72 cell panels (10a/42v)
- Victron MPPT 100/45 TR
- Victron Quattro 48/5000
- Victron Cerbo GX
- MRBF (2 lug) fuses attached to battery positive and 150a fuse for inverter, 50a fuse for charge controller
This is all going on a 20' shipping container using unistrut racking - code compliance is not an issue on this particular setup but still want it to be safe and well thought out.
- I know a combiner (midnite or otherwise) would be "best", but since I'm maxing out at 100v/33a short circuit (more like 80v/25a real world) and the runs are relatively short (everything lives in the container) would doing MC4 15a fuses to protect each series and then a 3-1 connector be sufficient? It represents a pretty significant savings, ease of installation, etc. Do I still "need" a disconnect between the controller and the panels?
- Grounding... The plan is to install a ground rod right next to the container, which will be bonded to container itself (probably a WEEB lug) and all the equipment. Was going to use WEEB lugs to daisy chain each panel to the next, then throw a WEEB lug (or 2) on the unistrut. Is this sufficient? Fortunately the container is up against a bank and not at all a "high point" in terms of lightning strikes, which lessens that risk to a certain extent.
Really appreciate your feedback on this!
