Hi,
I have been doing a lot of research. Contacting companies for quotes, watching youtube videos, looking through data sheets, trying to find DIY resources, etc. This forum has been a very valuable resource for me.
I am planning to install approx 40-45 panels. The estimates are around 16-18 kW. Specifically looking at the "Canadian Solar 400W Mono-crystalline Solar Panel (Black) | CS6R-400MS-HL" panels. These will be facing Southeast, so I'm not expecting full production.
I have decided that the benefit of microinverters or optimizers is not worth the additional cost for me. I really like the option of Fronius inverters with rapid shutdown modules. I get some shade in the area where the bottom row of panels will be installed during the early morning hours. I want to benefit from the shading software as much as possible.
Fronius inverters only come with two MPPTs. I am assuming that if I connect all the panels to only two MPPTs that I might not see the greatest benefit of the shading software. I am thinking that I could split the panels into three strings. Will the inverter shading software be more efficient if I split the panels into three strings across two inverters? Or, do panel bypass diodes and Fronius inverters work well enough with shade compensation that I won't see a significant enough benefit to make it worth having two inverters?
