Sun2000 optimizers - how to?

Dear members,


just got my PV system installed. The inverter is a Sun2000 5ktl M1, 10pcs 450W halfcell panels with a Sun2000 optimizer on each. All panels are on one string.

Now the panels do not face exactly the same direction, also there is some shading on some panels.

My question is how effective/intelligent are the optimizers? Can they bypass panels completely when shaded letting the others do their work without limiting them?
What exactly are the restrictions/limitations of these optimizers?

Thanks.

Hello,
optimizers are for this job that You described. When (for example) three of PV panels are in full sun and last are shaded by something, optimizer just bypass weakest panel. So, the worst or temporary shaded panel will not be a blocker for current. I have Foxess T10 with 545W Jinko panels (in 2 strings) and I used for under all panels (18 pcs) optimizers TIGO TS4-A-O.

When I compare my PV production before vs after I installed this optimizers, I see the difference. My daily drawing chart of total kWp production is smoother and at the end of day my installation produces more kWh comparing to days where was without optimizers.

Just remember. Shaded panel is the weakest part (and also a blocker for current) in your string. Using optimizers you are removing this issue from your installation.
