I want 6 240w panels they would be the santan ones about 30v a panel. Was thinking 3 in series parallel 1.
Should be 90v at 18 amps or so. I wonder if 2 epever 40 amps could run a group of 3..hmm
Any suggestions anyone?
Or should I just stick with what I have.
6 100w monocrystalline hf panels 2s1p
60v 10amps into morningstar ps-mppt-25m usually see 15 amps go into battery bank. Today I saw 15a of just one 240w panel with said cc after mppt conversion . And 8 amps in at about 30v
Together it should be close like 1kw. But I can return all 6 hf panels and switch to 240w santans

2s1p = 2 panels in series, just 1 string of panels, 2 total panels in the array.
2s3p = 2 panels in series to a string, 3 strings in parallel, 6 panels total.

Assuming you have a 24v system, right? If this is 12v you're going to be in trouble.

On The SanTan 240w Panels:

The VoC is the number to pay attention to when calculating voltage for your SCC, those panels are 37.2 VoC which limits you to 2s strings. Yes, you could do a 2s3p system with fuses on each string and get your 1440w max to the batteries, it should top out about 36a-ish so a 40a should be plenty. A 2s3p system should give you about 74v @ 25a going into your SCC.

On The HF 100w Panels:

If you're getting 60v @ 10a to the charge controller that means you've got those in a 3s2p config. 3 panels in series to a string, 2 strings, 6 panels total. It sounds like you've either got shading or angle issues because your Morningstar (Is this the one?) should be pretty much maxed out at 25a-ish. The HF panels are known to have issues working in parallel with each other and that may be a significant nerfing on that array.

Best case scenario would be to add the new Santans on their EPEver controller in parallel with the existing HF panels for 2Kw-ish of panel, but that may not be physically possible.

If you can only have 1 set, then go with the SanTan's for 1440w of panel over the HF. In a perfect world if you had another SCC that could take 150-200v of PV input I'd put all 6 of the HF panels together in series as a single string to avoid the paralleling issues. Sadly you're just over the max VoC of that Morningstar's 120v limit unless you take out a panel and go to 500w in 5s1p on it.

As a side, how did you get the HF panels into 3s2p without lopping off their stupid SAE connectors? Adapters? You won't be able to return them if they've got MC4's or the lime on there.

Today on a cloudy day I saw almost 35 amps out of the EP ever with the Harbor freight panels the the morning star with 2 of the Santana fathe Santana panels was about 16 amps
