Hi, went with the Solahart 6.6kw.
21 x solahart Silhouette panels
The inverter was a Solaredge SE5000H
21 x solar edge P370 Optimises.
Full solar edge monitoring
The advantages are if one panels stops working, the rest continue to supply power.
The full monitoring let you know which panels are working and the wattage output.
Due to heat on roof issues optimises are better than individual inverters on each panel.
Check this with Solahart, my rep extremely well informed and articulate about the advantages.
Main thing to watch for is installation and the antenna for the system. Inverters need to go in a cool sun protected place, sometimes WiFi can struggle to get there.
Make sure this I working before you pay final instalment… cheers
