I have a couple and they can routinely produce 104-105% of rated power through the EB150.
so, what should a beginner start with 300 watt panels, or 100 watt panels?...just looking so far...
prob will build a 24 vac system...I may go to a 48volt system
I started out wanting 12v panels, then the panels I wanted were sold out, so I opted for the 24v panels. I have 2/25v/200w panels, ordered now..I don't think it really matters, larger panels can be found cheaper often, and I suppose less connections/wiring, but heavier. largely it depends on your application and preference and the space you have available, not your level of expertise. Large panels are more often used for stationary residential or commercial systems, small panels on boats and vehicles, but plenty of vehicles opt for large panels too.
Small correction 24V DC
How large of a system are you intending to build (what array size, inverter size?) and what purpose/application?
Thanks for the remarks! To be more clear too - my panels are around 22v open voltage, they say. Since I'm running a 24 volt system (MPP Solar, as you show here) I needed to bind them together in pairs to get "over" the 24v input so it would work. <-- All of this isn't news to you, I'm sure.Something doesn't sound right, maybe take a meter to them to make sure the Voc is good on all of them? Also, the -MSD version is 145 VDC max PV input. I would run them in series.

Yes, as Steelhead alluded, running all 4 in series will get your array voltage up towards the MPPT sweetspot.Is there a "better" way to set up these four (4) 100-watt panels that feature 22± voc each
