Good information as usual, I'm leaning towards a Sunny Boy invertor with wind turbine capable. We get a lot of wind in the winter and a lot of sun in the winter.
I just looked at all my bills for one year. my average KWH per day is = 38. So an 8 KW system would be about right! That is a lot of panels. I may start with a 5 KW but rack for an 8KW. I'll need to see if I have the room on my Shed roof. Shed is 24×40Older model Sunny Boy have MPPT algorithm options for wind/hydro turbine. The newer models only algorithms for PV.
At least for wind, a dump load and voltage limiter is required between turbine and Sunny Boy.
If intermittent wind power is fed through a UL-1741 inverter, whenever power drops to zero the inverter will forget grid had been good, waits for 5 minutes of DC present while monitoring grid before feeding again.
You might want a DC coupled solution for wind.
Of course, if lithium battery and BMS that can disconnect, might still need a voltage limiter. I would think with lead-acid just a diversion regulator and dump load would be sufficient.

My solar was installed with a SunnyBoy inverter.How do I use Suny Boy? It is 240v inverter

Are you saying that what's marked as Neutral need to be connested to one of the panel phases??Either connect it a dual breaker of a 120/240V panel
? would you be so kind to provide drownings to how to use single phase 240v investor. I'm sorry but I'm confused ?. Appreciate your time. ?If your inverter has L1, L2, N connections, then typically it will auto-recognize 208V, 240V, 277V when all three are connected.
I use some of mine that way. Others, I hung as replacements where only L1, L2, Ground were wired through conduit.
In that case, I placed jumpers differently to tell the Sunny Boy which voltage to expect.
The ones I'm using also have jumpers to specify positive vs. negative ground PV array (grounded by GFCI fuse inside inverter.)
Another model I've used is transformerless and has ungrounded array. Most of the newer one are like that, but it is more important to have PV panels which don't suffer from "PID", degradation which occurs if grounded in a way they don't like.
So it is not a single phase inverter. I like it
ThanksMultiple orientations. 8kW PV will be just about right for a 5kW inverter without clipping.
