Hi all,
Some one sent me a private message. There seems to be confusion about what I recommend--so here is a clarification.
Here is what I believe.
For systems under 500 watts it is hard to beat the Grape 40 amp controller. (snip)
Thanks pianotuna. OP here.
Just a follow-up based on a comment a couple of posts back by another poster about PWM controllers frying if getting too much voltage. If I have those solar cynergy semi-flex panels with the following specs (Vm 20V; Im 6.0A; Voc 22.8V; Isc 6.65A), and wire them parallel, will the Grape Solar handle that voltage OK (without "frying") It seems these panels have a somewhat higher voltage than regular panels. Thanks.
