I'm looking at the Growatt/MPP/possibly EG4 Solar options now on the market.
After extensive research on panels, specs, understanding VoC, Currents etc. I realise I'm confused at split phase outputs.
Where I live we use a strange combination 115v, 50hz and also 230V 50Hz for bigger appliances. We use L1, L2, N. 3 wires in from the utility.
Now I'm seeing units being sold for USA as split phase once you have 2 in parallel.
But also I was advised that these have no low freq transformer so the 120legs can go out or sync? And I may have 115v on one side but could possibly have a difference under load on the other leg.
I'm not an electrician just an avid DIY is this how it works? In order to do split phase as I require into a panel with 2 120v legs and N,
I need
1). a split phase unit with a low freq transformer like a Growatt SPF 6000T DVM MPV.
And NOT
2) two 2 EG4 3KW models in parallel creating split phase
Any help here?
Also if this is the case, why is it that way?
