I was initially going to go put in a 24V system (MPPT, inverter & batt) in my ambulance conversion, but now I'm looking at 48V All In One systems. But I'm really stuck on the concepts of Wake Up voltages and Start Up voltages. In threads that reference these terms, the MPPT wake up voltage appears to be higher than the minimum voltage needed. I'm not even sure if this is an MPPT issue or AIO or even panels or all of the above.
I will have four 385W panels with Voc of 36.2V.
First, I was looking at the EG4 3KW, but now looking at a PowMr 5000W POW-LVM5K-48V-N SRNE rebadge with a 120-450V range. While I can theoretically hit the range with my panels in series, since my panels will be laying flat on the roof I worry that I have to wring every possible volt out of usable sunlight and I need to reconsider.
Can anyone point me in the right direction or enlighten me on this issue? Is wake up voltage the same thing as start up voltage? Does an MPPT's voltage range consider in a system's overall efficiency?
