OK I'm sorry if this is beating a dead horse, here, but I just need to know definitively how this works. The general consensus has been that it's a pain and not really worth it and that one should just use the overpriced proprietary expansion batteries etc. But please just humor me. \
If I want to use my power station on a regular basis to power my home (as I have been doing), and expand it using say, a 48V golf cart style battery hooked up to its solar charging port, and be able to charge that battery from solar panels at the same time... is that possible? And what exactly does that look like?
Is it just Panel Array > Charge controller > external battery > Power station solar input?
I currently have an Oupes Mega3 (3kWh) with 2x B2 expansion batteries (2kWh each) for a total of 7kWh. It's actually been a great setup for powering just the lights, fans, fridge, router and screens for my little house. It does tend to be at 10% in the morning, though, and I'd love a bit more, but these damn 2kWh expansion batteries are a grand each. For that price, I can get 5kWh with a big fat after market battery. The one thing I love about the Oupes is that the power station and each of the expansion batteries has its own MPPT with 12-150V of input, which not only makes it very easy to scale up your solar input with your storage, it also gives a ton of flexibility for the type of janky setups I love. I currently have 3 different arrays of different sized panels charging them. A 48V battery could charge one of these nicely. I'm just wondering how I would do it without having to disconnect and reconnect stuff every morning and night. Or burn my house down...
TIA!
