Corrections:
6:34 I over-simplified how the optimiser manages the current. In reality, the inverter first maximises the power from the panel by adjusting the voltage via MPPT, then performs a DC-DC conversion, decreasing the voltage to bring the current in line with the rest of the string.
7:45 Actually, some of the bypass diodes will only kick in if there is a difference in shading across that particular panel. If there is shading across the whole of the panel (as in the diagram) the optimiser should still be able to manage that.
14:17 Oops - the total production should of course be 3.6kW, not 4.8kW.
If you're getting a lot from my videos, and would like to support me in my efforts to help everyone, here are a few ways to do this:
1. I've not long started a Patreon account, which gives you access to the "pro" editions of my tools: [ Ссылка ]
2. If you're thinking of switching energy supplier to Octopus Energy. If you call them and give them my referral code ("blue-wind-201") and my name ("Gary Waite") and we'll both get a £50 credit to our accounts as a result! [ Ссылка ]
