I hear you.
One of the concerns with larger panels is getting the minimum startup voltage. The Deye wants 150v ish .
The other issue is staying within the max wattage (6500W per inverter) stated on the sideplate.
I have 3 mppt's open with about 1.5kWp capacity left each.
So the tricky part...
I'm sorely tempted to go grab some of those panels, 18-20 (assuming they are 45-50v ish) would max out my system nicely.
Why the negativity?
I can't think of much that can break on a panel?
Or would it make more sense (the generator was this years upgrade) to go with my original plan of next...
Go to an auto paint/panel-beater type supply shop and get the double sided tape that holds car badges on.
You only have one chance at placement, so be careful, but that stuff really sticks.
I am totally off-grid running two houses with all of those things. Generator is there for cloudy days and when everyone is a bit heavy in these few weeks of winter. Summer I have more power than I know what to do with.
I'm not interested in being a "power policeman" and let everyone run what...
They are and that's my understanding as well.
Even on a practical level, if you are designing an inverter with feed back capabilities you would need to do all the bits that NRS is concerned about just to stop your product from trying to run the neighbourhood etc.
We are not the only market that...
That's all I did.
We had a three phase ESKOM connection so I spent some time looking at options and decided that since it was only the borehole and one of my machines that actually needed three phase it was simpler and easier to just go single.
So a single phase borehole pump and three 5kW...
