    Growatt 3000TL LVM 48P-AC output wire size

    I don't think I've seen an installation with the conduit actually being put all the way into the unit. Just close to it, then the wire is put through. I'm not sure that conduit would fit into the openings. The holes for the PV and DC inputs are about 1 1/2".

    Growatt 3000TL LVM 48P-AC output wire size

    This might be a ridiculous question...where would the ground wire go? (the 8/2 wire noted above) There is only a positive and a negative port for the PV input. I just want to be sure this will work before I order the wire. Thanks for your patience everyone....

    Growatt 3000TL LVM 48P-AC output wire size

    Would it it be better to have the inverter and batteries near the breaker box? I thought I would be making it worse to have such a long run from the combiner box to the inverter.

    Growatt 3000TL LVM 48P-AC output wire size

    My unit is the 48V. The manual of this Growatt specifies 8 gauge for the AC output. Does it matter how long of a run that is? My distance between the unit and the breaker box will be about 260 feet. My panels are going into a Watts247 combiner box, then into the Growatt. Does the combiner box...

    Help with Growatt SC 48120 installation

    You are correct, my friend. I linked to the wrong manual...hence the mismatched number of pv inputs. Here is the spec sheet for my unit.

    Help with Growatt SC 48120 installation

    The Growatt is an all-in-one unit. My 60' run would be coming from the farthest panel, along the roof, then down into the combiner box. What would be the proper gauge wire for connecting the panels to the combiner box?

    Help with Growatt SC 48120 installation

    Correction: I just received the Growatt and unboxed it. It only has 1 PV input. The diagram in the online manual showed two inputs.

    120A Charge controller from Watts 247

    Does anyone have experience with this particular charge controller? One picture of it looks generic...another shows "Growatt". https://watts247.com/product/sc48120/ Thanks!

    Making a parts list for new 24V system with used Santan panels

    I appreciate the help. I may just not use all 12 panels. It's getting pricey to try to use all of them. That leaves me some spares in the event of damage or failure. Thanks again!

    Making a parts list for new 24V system with used Santan panels

    Two values for max PV Voc: The product states 150V (138V @ 77 degrees F) I don't understand the range. So, I would be better off to just use a single charge controller? 80A? 100A?

    Making a parts list for new 24V system with used Santan panels

    I was planning to use 2 of the 40A controllers (see my OP). I had hoped it would work well to put 6 panels facing east and 6 facing west, then run 3S2P to each scc. I could probably only face south by tilting some of them. I wondered if it might be a waste of money to buy a higher amp scc...

    Making a parts list for new 24V system with used Santan panels

    I should be receiving my 250W used Santan panels this week. I haven’t ordered anything else yet. I initially planned to use a LV2424 all-in-one, but they keep going out of stock…and I can see some benefits of just building a 24V system. I’ll list the main parts I’m planning to use, based on...
