If you want a DIY-friendly option, it's best to look towards DC optimizers. They are installed on each panel and they provide a steady 48V output. They also do MPPT tracking on the panel level, so you get the best possible performance if you have some shading.
Unlike microinverters that are notoriously unreliable, DC optimizers so far have excellent long-term reliability.
- nanomonkey 2y agoAre you suggesting using a DC Optimizer from your solar panels to charge 48V batteries directly? This would be interesting. It's the first I've heard of optimizers being used for anything other than prior to an inverter.
- cyberax 2y agoYou absolutely can do that. You still need a charging controller and a BMS, obviously. But you can avoid the AC round-tripping.
- nanomonkey 2y agoNice, the 48V batteries I have already have BMS's...any suggestion for a nominal 48V DC optimizer and charge controller?
- cyberax 2y agoTigo is known to work. I've heard that SolarEdge DC Optimizers don't work without a SolarEdge inverter connected to them.
