I purchased a Growatt SPF 3000TL LVM-ES and am trying to figure out what the solar mppt max voc is. In the manual on page 4 it says the mppt range is 150v - 250v and a voc of 300v. But on page 12 it says max PV array open circuit voltage is 250v. If the unit can handle it I would like to set my strings up to have 258.3v voc and an optimal operating voltage (vmp) of 208.6v. However, I don’t want to mess up my inverter. I’m fairly new to this stuff and might be interpreting something wrong in the manual.
If any can give me some insight it would be greatly appreciated.
