From Robert at Maximum Energy
I have never used Tigo optimisers before. I want to replace 1 solar module in an existing system. The existing panel rating is 230W and I want to replace with a 310W. Can I install 1 x Tigo optimiser to the new 310W panel and connect it in with the remaining 230W modules in that string? I am not looking to monitor or anything like that, simply connect a panel of bigger wattage to an existing string.
Is the information from this article still valid?
