Hello,
This is my very first post and I'd like to start of by saying that I'm really glad there exists a forum for solar related stuff to help us advance.
My equipment
3 1000w on grid inverters
10 300w panels
2.5kw inverter
4 150ah batteries
Inverter 1=4 panels
Inverter 2=3 panels
Inverter 3=3 panels
All of these inverters plug into one strip of outlets on the 2nd floor attic.
I plug the 2.5kw inverter with the 4 12v batteries into a wall outlet closest to the main panel in the garage.
I don't have permission to tie up to the grid yet so I've been turning off the power to the mains and then plugging in the inverter and turning it on. Everything was working just fine. I then realized that my batteries weren't lasting as long as I expected, so I looked at my wires and realized that my wires were too thing and upgraded them to 8AWG.
Now this is where my problem started. The inverters were pumping out power like they should according to a few DC power meters that I picked up. The problem was that they seemed to be pumping too much power because the inverter in the basement which is acting to fool the on grid inverters on the roof keeps "flickering" when it's really sunny outside. I measured the voltage of the battery bank and it was 60 to 62V. I measured individual batteries and they were around 15.77V. I turned off a single inverter and the flickering stops, doesn't matter which one so I know it's not an issue with a faulty inverter. After I do this anD measure the battery bank it's 50V and individually around 12.66V.
The 2.5kw inverter is plugged up with only one plug that is connected to the output.
Can anyone help, because right know I have to climb into the attic and play flip the switch to control my solar output. I know my system is designed to be hooked up to the grid so the excess will be sold, but if you think about it, if the grid goes down for a day then the system will function exactly like it is right now and will "flicker" (the inverter will keep starting and stoping).
Thank you
Chuck
