Have you ever thought of a career in teaching? I have to commend you on your patience when a beginner (we are in beginner’s corner aren’t we?) asks questions which may not match your superior intellect or use the correct terminology. Bravo on your boundless encouragement of those less confident...

I seen on YouTube that Growatt has something similar to Charge Block. But if I can’t get the required VOC to power the charge controller, is there another solution you’d recommend I look at? Is there such a thing as an inverter that uses mains power to power the charge controller?

Haha, no, definitely not expecting them to work at night. I think my main concern is that I go and buy the Growatt inverter, four panels and a battery and find out that on a really cloudy or winter’s day, the panels can’t power the charge controller. The shed has mains power which I’m fine with...

So the SPF 5000 says 150v ±10V so I’ve aimed for 160. That’s the best I can do really with the size of the shed roof - four panels at around 40-43 volts. If the VOC drops at night, how does the charge controller continue to work? Does it rely on a battery? If no battery, does it just stop workng?

Thanks Bentley, that clarifies things. So another real newb question…does a panel’s VOC drop in low sun or at night or is the VOC constant? I’ve found four panels that can supply 160v VOC which is slightly more than what the SPF5000 asks for. But will this drop at night and therefore go below...

Thanks Sunshine So just to confirm, even if the inverter is connected to the mains, I still have to reach 150 VOC? Thanks

I’ve searched for the answer on this but unfortunately didn’t get anywhere so apologies in advance… I’ve just built a shed which I want to be off-grid. The roof can only accommodate three panels - does this rule out the SPF5000 because the panels can’t generate 150v to power the inverter? If I...
