That's 'THINK' before you disconnect. DC under load can fiercely arc and is very dangerous. The arrows being away from the center are inferring disconnect. If they were toward the center it would be think before connect. The symbol I think you're referring to tells you which end is female and...

Hi Markus I just want to share my experience with pretty much exactly what you're doing. I'm a electrician in the uk but my experience with day to day maintenance of a battery bank is woefully low. I opted to over spec my inverter/charger and everything else I could afford for future use while...

Just a heads up I had this issue with my off grid mpp solar and couple of pylon batteries it only happened on a few led lights not all, turned out to be the dimmer module not liking the voltage changes. Changed it for a different brand and all is well. Fyi the dimmable leds in the house show the...

Hey i'm not really technically up to speed on the subject but I had a similar issue with different wattage panels and this article helped me out...to basically use matched panels :geek: https://solarpanelsvenue.com/mixing-solar-panels/ There is also the issue (and please correct me if i'm...

No constructive comment here, I hope you get it sorted but please say it's a ZX40ST "with a top speed of 25mph and achieves 0-20mph in approximately 20 seconds". That thing is just fantastic and I want one. Just sayin' :geek:

Hey Milty did you get this sorted? Just curious.

Outstanding!

Surely not all your panels are different ratings. You can series them by similar current ratings then parallel the groups. In my mind stepping up is just going to be a dramatic waste of current. Stepping up as you increase the voltage the current falls. You'll have the right voltage for your...

Funny you mentioned the 48v system and only 2 panels. It's exactly the situation I had as I was originally going for a 24v system. Changed my mind to 48v, found out the same panels are no longer available so got one very similar but just slightly over spec'd to the others and the 3 now produce...

I'm a little lost when you say 'parallel back bone', does that means essentially having the 9 panels in series and the 18 in series then paralleling them together into 1 x mppt/pwm? I would I suggest that will be bad as the whole system voltage will be dragged down to the side with the least...
