Re: [Emc-users] How come.... Batteries

Redox flow batteries might be a cheaper alternative. It might be likely not all available charging cycles are used for a long lasting battery. 20 cent per kWh hour, price for electricity I found in USA is in the range 7 - 23 cents per kWh, with an array on roof storage cost might be if you are

Re: [Emc-users] How come....

If you are building a battery-based power system and space and weight are not issues then what you should care about is the "total watt-hours per dollar". Here is an example,... You have a 100 amp-hour lead-acid battery at 12 volts. If it is lead-acid then you can only discharge to 50% if you

Re: [Emc-users] How come....

Great analysis, Chris.  There's no way I'd use any lead acid battery technology in a new off-the-grid solar power system. A friend of mine replaced his old lead acid batteries with a home brewed Tesla Power Wall, built from the battery from a wrecked Tesla Model S automobile. Part 1 (23

Re: [Emc-users] How come....

One of these days I'm expecting to see someone build a power wall style installation that uses lithium ion power tool batteries plugged into sockets. Imagine a closet full of Ryobi ONE+ 18 volt batteries. Buy them used, old ones on clearance etc. The practical aspect is the ONE+ batteries have

What would be very useful is a little PC box made so it's built in peripherals leave a 64K free space between 640K and 1024K in the default location for LIM EMS 4.0. Even better would be a 32 megabyte chip on board for a hardware implementation of EMS. With today's tech-fu that chip could be
