I guess what makes this different than EG4’s all in one inverter plus a 5kwh server rack battery, is the integration of software and hardware.

I think you have a great shot at being successful. Because the cheaper options, software isn’t great or fully integrated with the hardware.

These systems are a fraction of the cost of powerwall though.

I learned a lot about the DIY side of this from Will Prose on YouTube. It’s amazing how much markup Tesla has on top of LFP batteries.

Correct, integration is key for a seamless consumer experience.
