I’m just having fun with an anker 521 while I renovate my house, I have it in a cabinet with my laptop, homepod, everything I charge, would love to feed it from solar.
It only accepts 65W from solar (11-28V = 5.5A, 65W Max), however they ship the thing with a 100W panel (28.5 open circuit, 4.5A)
Guessing I can find pretty much any panel I want in that ballpark, as long as the open circuit’s not above 28v
With anything else in electronics I laugh at kids saying “not too many amps on supply it’ll explode!!!” but ai was wondering if I found a, say, 200w panel that kept under 28v, would that be fine, or are MPPT controllers cranky when working with such drastically oversupplied panels?

Panel will probably be around 20 feet from the battery, any major considerations I need to worry about for this, or will power drop be negligible?

Finally, I’d like power monitoring on this (battery doesn’t have any telemetrics, its pretty basic)
Was thinking some sort of current clamp on the DC/solar input just before the battery, also measuring voltage, so I can establish power. Would then brodcast over MQTT/home assistant via an ESP.
Happy to DIY this, just curious if anyone has any recommendations for power monitoring at this voltage range
