  • What conduit do I use from wireway to inverters?

    I have two LV6548 inverters and a 6x6 wireway. I have a couple of beginner questions, I don't know much about conduit: Knockout hole sizes: The knockout holes on my wireway appear to be different sizes side by side. If the holes are different sizes, how do I address that? Conduit and...
  • Is this diagram correct? What would I be missing or doing incorrectly?

    I made a diagram in Microsoft paint (sorry for the terrible artwork). Am I missing anything here (even little stuff)? I'm a beginner to solar and have been researching for a few months. The system will be totally off-grid and have no grid-tie in, with it's own separate subpanel. Thanks!
  • Safety check on my simple diagram please

    Plan to run this as a backup system for now, will grid tie eventually. The transfer switch is already hooked up but none of the rest is yet.
  • Where to place the class T fuses and busbars? Boxes, enclosures?

    I plan to have my two 4/0 battery cables running from the EG4 server rack in 1-1/2 conduit running to my wireway (and then up to each LV6548 inverter). My questions are: 1. Where do I place the first 350A class T fuse and fuse holder (I assume within 12 inches of the positive EG4 Rack busbar -...
  • Has anyone managed to get 4 gauge THWN wire to fit on LV6548 inverter?

    I have a 20 foot run between my inverter and panel, I'm using two LV6548 inverters for a split phase setup. It looks like that would be ~54 amps for each separate wire run to the panel. According to the charts I've seen online, 4 gauge seems to be the best choice here, and 6 gauge would be...
  • What happens if the panel draws more than the inverter can output?

    Let's say you have a split phase setup of two inverters such as MPP LV6548. Together they output somewhere around 100-110 Amps. What if you had a 200A panel and the AC kicked on or something and you drew above that inverter output amperage. What would happen?
  • What should I use for a disconnect in between my battery bank and positive busbar?

    I need 350A, 48V I believe. Six-5kw EG4 batteries. This is the only thing I've found so far but not sure if it's right. https://www.santansolar.com/product/dc-disconnect-on-off-switch-350a/ I have a 300A class T fuse there as well, but want some additional safety by being able to isolate the...
  • Two different branded LV6548s, will they work together?

    I bought my first LV6548 a few months ago from watts247 and it was branded MPP solar, I bought my second one a few days ago from them again, but this time it was branded "Rich Solar". They look identical, but I just wanted to confirm they will work together? I'm going to run them linked together...
