If Gordon Moore’s Law is something to go by, the extraordinary processing leap in smartphone and other mobile gadgets has proved extraordinary: except for one particular little thing – lithium ion battery! And btw, yes, you do want to convert DC to DC when going from a PV array to a battery, at least if you want to so somewhat effectively the PV maximum energy voltage will almost never ever precisely match the battery charging voltage. But if you have a SolarEdge inverter, I bet you have MPPT optimizers and what you need to have is the grid transfer switch and the right hook up to automatically switch to battery backup when the grid goes down. I am also hopeful that flow batteries can compete well in the future as projected, but the present $ based on the Deutsche Bank report is clearly much higher.
Appears to me like there are a number of Tesla partners carrying out specifically that and they have set up an entire system for that. The #1 most important function is the automatic DC disconnect situated on the battery that will reduce the connection from the charging supply if any of the Lithium Iron cells are not adequately charging or discharging. If your battery only had 1000 cycles you can have three days worth and it will only final about 8 years so. but 5000 cycles is a entire new ballgame. The battery is rated for 2C. Its 1C rate is 2x 3.1A. So it ought to be very good for additional than the 8A rating, or about 12A.
The battery output straight feeds an external inverter to develop AC in a compete system. The aggressive method of Tesla (and Solar City) tends to make a lot of investors fairly uncomfortable-unless, of course, they take …Read More
