Are 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.

You absolutely can do that. You still need a charging controller and a BMS, obviously. But you can avoid the AC round-tripping.

Nice, the 48V batteries I have already have BMS's...any suggestion for a nominal 48V DC optimizer and charge controller?

Tigo is known to work. I've heard that SolarEdge DC Optimizers don't work without a SolarEdge inverter connected to them.
