We just switched from a Renogy 48v 3500 watt all in one inverter to a Growatt 48v 5000w ES inverter over the weekend.
We have 8 Renogy solar panels that are rated for max 40 VOC with 32 volt typical output. With the Renogy inverter, we were limited to a maximum of 140 volt input so we ran two sets of 3 panels (i.e. around 90-120 volt input).
However, it seems like the Growatt needs a minimum of 150 volts and can take up to 450 volts. We changed the former set up to now be 2 sets of 4 panels, and it is charging the batteries, but I'm wondering if it would be better to have one set of 8 panels all in series? Having 2 sets fo 4 panels means we are pushing between 125 and 150 volts depending on solar strength.
Also, the panel shows 230 volt right now at the top - wouldn't it only be able to provide 120 volts with just one inverter and need a paired inverter to create 230/240 volt? The instructions on set up are not as easy to follow compared to the Renogy manual.
Would I need to switch my generator input to 240 volt? If I do, why does it only have ground, load and neutral connections? I assume it is because there would be a need for other load wire to go to a second inverter - but not sure as this is the ES version.
