These days, I recommend using DC optimizers that are attached to each module. They provide MPPT tracking on a module level, and make engineering calculations simpler.
They are also much cheaper than microinverters, safer, and more reliable.
- mitthrowaway2 3y agoAny specific examples that you would recommend?
- cyberax 3y agoTigo optimizers are nice, and you can have just one optimizer for 2 modules. It's mostly meant for commercial bifacial modules, but it can work just fine for 2 completely separate modules. You can also use their cloud monitoring thingie to remotely track each DC optimizer's health. Or you can use SolarEdge optimizers, they are simple and cheap (<$100 per module). Both support automatic shutdown, so you can safely de-energize the entire system if needed. It's a problem for classic string inverters.
