Hi Everyone,
Honestly: I am not an electrician and understanding 12V has been a challenge - I am very new but just like learning and growing. Like most people here I started to build my own portable solar generator because of Will Prowse's YT videos. Fast forward 8 months of thinking I have this all figured out (my own arrogance) I thought all I had to do is crimp, plug and play...uh, not quite! I bought Will's book which was helpful - so I took that and tried to create a 24V system. I won't bore you with my setup - only the relevant parts: Panels, SCC, batteries, fuses, and wiring. I know that pictures are good so I have included one. More reading is required but I don't know which topic to tackle. I may have the wrong fuses but I'm willing to put myself out there for utter ridicule...but hopefully I learn something new.
question in a nutshell: why the major voltage reduction reported by SCC - is it because of my inputted values that I clearly don't understand?
Dilemma: From what I understand, the panels are supposed to bring in around 38 V each when not connected to anything and around 31V when it is (according to the panel specs). Wired in series I scope around 112-115 Volts on the multimeter just before I plug them into my generator, great! However, when I plug the panels into the SCC it reports around 26-35V incoming...it'll flash that it recognizes around 103V and then a few seconds later it'll read around the 20-35V mark. The amps are around 0.6A incoming. So, clearly I don't understand electricity and their values....I think. I've learned how to program the SCC through the MT50 - but some of the terms I don't understand (but will read up on)...here are my values I've inputted: It was hard to get a spec sheet from SOK (I'm not a FB user for their page) - so i found one from a reseller to get my values.
