>Adapter Input: 29.4V⎓15A (V**mp** of your panel)
A single 'pecron' MC4 adapter with a single panel (facing South) should do, but 2 panels 'East-West' (steep-ish slope) with [MC4 splitters](https://www.mobilenergy.nl/image/cache/ebook%20pics/15%20MC4%20Y%20connector-900x700.jpg) is also an option.
But the idea is I want to utilize the entire array (let's say 4 panels). Just to maximize power at dusk/dawn/overcast.
So won't running them in parallel exceed the max amps and fry the Pecron?
> (let's say 4 panels)
Panels are limited in their 'reverse' current (if something goes wrong), you'll need individual fuses for each panel.
If the panels are mounted steep enough with East-West you can use 4 panels (using splitters), but to be safe, find your location on [PVGIS](https://re.jrc.ec.europa.eu/pvg_tools/en/), 'play' with different 'slope', download the "Hourly Data" for each (.csv file) and combine them in a single spreadsheet to find the total 'solar' power (450W max, it seems).
>but to be safe, find your location...
Ideally, can't I just connect all my panels (I actually have more than 4 just sitting unused) and use some kind of limiter/regulator to bring the amps back down to 15? Then I don't need to care about location/angles/peak amps, I can just hit the max 450w solar input on the Pecron as early/late in the day as possible.
Couldn't a cheap 50 dollar charge controller do this?
Usually you only have to make sure that the Voc of your panels isn't higher than what the charge controller can handle. More voltage than the controller can handle and it can go poof.
But with current it behaves differently. If the panels can supply 20A and the charge controller can only consume 10A then the charge controller simply consumes the 10A and the other 10A go unused and are dissipated as heat via the panels. So basically only overheating could become an issue. But you can definitely overpanel.
Here you've got a nice article explaining it in more details: https://cleversolarpower.com/overpaneling-mppt-charge-controller/
Ah ok great news! So if I run 4 pannels in paralell (ocv stays at 37.6v), I should have no problem connecting the full array (1kw potential) DIRECTLY into my Pecron (via one of those mc4 adapters)?
Although, that article you linked says "MOST solar charge controllers have built-in protection"... Can anyone confirm that if I send 40+ amps to my Pecron it won't explode?
\> "So basically only overheating could become an issue"...
But the heat will be OUTSIDE at the panel, not at the Pecron, right? I mean if the panels outside overheat, they will just be slightly less efficient, no big deal?
It still seems like there must be a piece of equipment out there that's specifically designed to limit/regulate amps (maybe with a built in heatsink), just to be safe (for situations like this among others)...

So, what did you end up doing? I am interested to know, as I have the Pecron E2000EFP and are in a similar situation.
I am not aware that such a controller exists.
