Which Optimiser should I use?
I have an 8kW SunSynk inverter, 2 x 5kWh batteries, and 5 x 455W solar panels. Two to three panels get a lot of shade from a tree in winter, causing my array power output to drop significantly. (In summer I peaked at 15.9kWh in one day, in winter it dropped to less than 3kWh.)
What DC Power Optimiser can I install? I live in Cape Town, so need something that I can purchase in South Africa.

I wouldn't listen to one person's viewpoint on Optimisers. Go with the general concensus. I have Tigo Optimisers fitted and they increased my output from day one. Thanks to the fitters, we were able to confirm.
Similar to Stuart, we are up around 7% on panels without optimisers.
I would agree adding more panels would be cheaper if your inverter can take more, and if you have the sapce, but if, like us, the roof is filled, that isn't an option.
