So I was able to get a hold of Signature and he said that the 18 is not a hard ceiling and that the inverters will just only draw 18amps. Said I couldn't hurt them. Told him I'd be running 207vdc into them at 19amps (assuming the panels are putting out full power) and he said that would be...

Thanks guys. I appreciate the input alot.

Hi Tim, so looks like 20amps. I included the panel label below. Also included is a diagram of the set up with where I understand the fuses should go. Look correct? So I need four 20amp fuses for this set up? Sounds like we have similar setups. I also have 6kw of panels going into the two...

Hey Tim, this is from a while ago but I am looking to get some fuses per this older discussion. I have a 5S2P set up sending 205 Vdc at 19amps into a Growatt 3000 LVM inverter. I attached the specs for it. I'm wondering what amperage I should get for the fuses. I called the place I bought it...

Yes to everything you wrote. I don't have a tilt angle or compass heading for you though. Sorry.

So one of the strings is all oriented the same, the other string has a slight difference between the two but not too much. So, 20 panels total, 2 parallel strings of 5 panels each. 2x So 15 are all the same, while the last 5 are at a slightly different angle but not much. Thanks for your help

The imp is 9.48 A and the Isc is 10.37

Oh, charging current is how much is going to the battery. I see, so I guess the PV input is the number I have to look at. 18Amps sure seems low. fingers crossed it can handle more than that.

Thanks Robby, according to the manual, the 80Amp number is the Max PV charging current, while the max PV input current is 18Amps. I don't know what the difference is between charging and input. I'll call them tomorrow and see. Thanks for trying buddy. I know this is an old thread.

I'll reach out to growatt and/or signature solar tomorrow too to find out if the 18Amp max is going to be an issue. Cheers!

Hey Robby, ol visionguild here. I'm sorry to bother you. I'm finally starting to hook things up. I know, ridiculous how long it's taken me. So I was looking at the manual and it says the max amperage for the inverter is 18amps. I see you have 22Amps listed and I do have the 5S2P set up...

Ok. Thank you Hedges. yeah, they're all going to be in the sun pretty equally. No real shade around except in the early morning as the sun gets over some trees, but after 10 till about 6pm they'll all be getting equal sun.

Thank you so much for all your help. I can't tell you how much I appreciate it. Good folks on here. Cheers Tim.

Perfect. Thanks. So I guess I'm ok on not using fuses then as I'm only putting 2 strings together but I should get blocking diodes for the two that are facing slightly different angles. Would I be getting two diodes? One for each + string coming from each group or just one on them after...

Thanks! I thought so. just saw your email about the junction boxes. Duly noted. Thanks. Ok, last question! Take a look at the pic I included, do I just need fuses on the + ? And on the two groups on the left, since I do have two groups in parallel facing slightly different directions...
