Hi, all. I've been reading over these forums and I'm having doubts on what I thought I "knew" and will humbly reach out for help.
After some late night research, I purchased 5 100 watt 12 volt 5.55 amp panels and a 20 AMP MPPT charge controller.
My belief was that I could run these panels in series (decreasing the need for larger cable to the controller) and deliver 500 watts, 90 volts at 6.7A to the controller over some 14/2 wire about 30 ft.
So, 5 panels, 100 watts each, 18 volt, 5.55 amps, I believe my math above adds up... but, something feels off, I got myself down a rabbit hole and I fear I may have made some errors.
Here are my MPPT specs:
* Nominal System Voltage: 12VDC | 24VDC Auto work
* Rated Battery Current: 20A
* Maximum Battery Voltage: 32V
* Max. Solar Input Voltage: 100VDC
* Max. PV input power: 12V/ 260W 24V /520W
* Self-consumption: <10mA(24V)
* Charge Circuit Voltage Drop: <=0.26V
* Discharge Circuit Voltage Drop: <=0.15V
I am charging a 375 AH bank with this set up and running 2 inverters, 600 watt pure sine and a 1100 modified sine.
We are officially Off Grid on our new property this next Monday, so I'm double checking my plans... and I hope it's just me having the jitters.
Did I screw up? Is this going to work? Please... man, my wife will kill me.
Thank you in advance for your help!
