Well then I retract my previous statement.

First, I very much appreciate your honesty. I also appreciate that you showed the information for the parts to compete with my proposed electrical solution.

However, your product is likely not something you would use in a home solar setup. This is more of a camper/RV power system. A real system would be significantly larger and more robust. Adjust costs accordingly.

I agree with you on the scale of the electrical solution I showed. It is a very small setup, and I used that specifically because it was a simple all-in-one turnkey solution. Getting into a system large enough for a home gets more complicated because we have to raise questions about where that home is to design a solution. Different countries have different regulations as far was what equipment is used to comply with local codes and ordinances. The solar panels on my house in the USA and the batteries in my basement along with the support devices and wiring would be different in a country like Australia. The costs would be significantly lower too for an equally performing system in Australia.

I would love for home Hydrogen systems to offer a superior performance or pricepoint to current purely electrical ones, however I see that to be difficult simply with the require conversion losses for consumption. One angle Hydrogen could succeed is in energy storage assuming the technology is developed to do so where the Hydrogen would be used for combustion for home heating. However at this point I don't know of any technology that would be even close to more efficient, better performing, or less expensive than many other non-Hydrogen solutions on the market right now.

I keep watching the space though and hoping Hydrogen can be a viable energy. I'm just not seeing it yet.
