Hi All, I have recently had installed a nominal 6000W system.
15 400W panels
6 West Facing
6 East Facing
3 South Facing
All on a Growatt Hybrid Inverter.
One string for the west panels and then the other for the east and south panels.
The south panels have Tigo optimisers fitted, in the belief that when the east panels fall into shade in the afternoons that they (the south) would continue to generate. This doesn’t appear to be the case in practice, and have the awful dread that the optimisers were needed on the east panels rather than the south to allow this to happen.
Is that correct, and what sort of output should I expect from 1200 W south facing panels in the afternoon hours? At 4pm today the west 6 were nearly at full nominal kWh producitivity (2.2 kWh vs 2.4 Max) where as my other string was only producing 0.25 kWh, and I’d be expecting much nearer the 1.2 kWh south facing that were still in full sun. I suspect my current reality is that the shaded east panels dictate the afternoon yield of that string. Hope that makes some sense, and that I can be put out of my misery and find a solution.
