My wife and I are homesteading in Hawaii. I almost have the house dried in. I am wanting to get my solar set up. I have a MPP Solar 5048GK that has MPPT. My panels are Sunpower 330w, 50.9Voc, 7.88amp monocrystaline. The inverter is rated for 5000 watts and the MPPT is rated for up to 450v.
A friend has told me to keep the voltage below 400v for longevity of the MPPT. The manual rates it up to 450v. I have calculated that I can run 8 panels in series and come up with about 408 volts. The problem is my wattage seems low.
My question is: Am I wiring them to get the most out of my inverter? Is there an alternative to be able to get more wattage without having to run larger than 10ga wire? I also have a large amount of these panels to use.
Additionally, I am going to have to run a modified toroidal step up/down transformer to split the 220v single phase inverter output to split phase. Is there a better option to achieve split phase?
Thanks!
