I'm working on a small system for my shed; planning to use the Eg4 3000 ehv-48 inverter with an EG4 LifePower4 48V battery. I'm a little concerned about the inverters PV input voltage range, but not convinced I'm looking at it correctly.
There's enough space to mount 4 panels on the south facing roof. Looking at panels from Santan (half-cut, mono, PERC), the typical 300-350 watt panel has an operating range (VMP) of about 30-35V, and the EG4's PV input range is 120VDC - 450VDC. So, if wiring in series, the strings output voltage (4panels x 30volt = 120v) would just barely be enough to work. Is this close enough, or, should I be shopping for a different inverter? Or, is there a different way to solve it?
