Pros: power output, rated output
Cons: AC outlet count, repairability
A tested solar over-voltage condition cleared automatically once voltage dropped, avoiding a manual reset.
Pros: power output, rated output
Cons: output stability, voltage regulation
The protection system continuously watches cell voltage and is repeatedly described as reassuring and well developed.
Pros: rated output, peak output
