So, I have a 10a controller. If I attach 3 100w panels in series, I will in theory producing at 50+ volts. If I am producing 12v output, am I going to have over amp issues with the controller? Thanks, and remember, we learn from you, so please, if you are going to faceplant, do so quietly;)

I have 3 slightly different voltage panels(1-18.1, 2-18.9). Can I wire them in series? And any particular order?

Any reason I can't use 12 and 16 gauge speaker wire to connect panels?

Does the difference between panel voltage and battery voltage affect efficiency?

So I have a 10 amp Tracer AN and expect to be putting 280 theoretical watts at 36v, and putting it into a 24v battery pack. My max amps coming in should stay under 10 amps, but stepped down to 24v, the theoretical amps outbound are 11.6. Should I be concerned?

I have several 30w (17.4v, 1.74a @ pmax) panels I was thinking of rigging a DC/DC converter with 5v 3a output. Am I leaving power on the table?

So, a friend of mine bought a "100w" panel from Giant of Sun to use as a 5v phone charger. I know this is a noob question, but when I but my volt/ammeter on it and attach a load(battery) the meter shows 5v but the other gauges show zero. ?!?

I have a HF 100w kit, as well as 200w renogy panels on a epever 20amp mppt scc. Right now I have a single 100aH SLA . If I am charging/operating usb and 12v devices, does the scc provide the power directly to those devices, or is it both charging the sla and drawing from it to charge said devices?
