Well, I might have just made my first big beginners mistake! I bought some used panels which were rated at 29.8v max output at up to 8 amps. Being filled with cleverness and self confidence I believed the word max meant "maximum", e.g. that the voltage would not exceed 29.8v. Alas, I hooked up a couple, out them in full sun, and recorded 65v at 8.3 amps in my multimeter.
The problem is that I was also planning to not get a charge converter but to use this with my Anker 767. It can draw 20amps at 60v.
Ooh, I thought I had nailed this one
Now I'm looking to try and find a voltage buck converter to cap the output of the panels at 60v. Any suggestions? It seems like I've gone to this trouble and now only have an inefficient way to shunt power to the Anker 767.
Context: this is an off grid workshop battery
(Shout out to watchdoc for the great Anker threads)
