I’m planing a “simple” solar setup for my new house:
- 15 * 355Wp LG solar panel ~5325Wp total
- 20kWh lithium battery storage (2* LG RESU10H probably)
-> the objective objective is a self-consumption grid-tied system
and I’m blocked by several points:
one-phase vs trhee phase inverter ? can i use a 3-phase inverter (better performance, easier to feed the grid) if my grid entry is one-phased ? (most common setup in households)
better to use one 5kW inverter or 2*3kW ? it seems to me that using stacked smaller inverters allow the SP to produce usable power at lower input voltage ? and stacking would allow me to get 6kW output for night time or backup power.
I often see both standard SYMO and SYMO HYBRID inverters on existing setup: what is the interest of having both when the Fronius guide recommend only one depending on the existance of battery storage or not…
Thx a lot for the infos !
