Status: Just an idea
Solar Power is the solution to power future households. But to make use of its advantages a good storage of the electrical energy is essential. Best would be to save a sunny days energy to be available at night. More and more charging and inverter devices are on the market but storage is still too expensive today.
My Idea is to use several 12V plumb lead acid batteries being controlled by XMOS to make up one big storage at 24V. They are individually charged and recharged for best performance and optimized for a long battery life. One could use different capacities and even different life time stages. So with cheaply available batteries from the secondary market, we can make affordable and competitive storage.
