If you’ve followed this project from the beginning, you know that one of the reasons I wanted to go to a 48V DC system was for generating AC power.  At 48V, generally you get more capacity (in terms of power) for your money; because of it’s popularity in off-grid installations, there’s arguably more choice, particularly…

I mentioned in the previous post that a new battery  monitoring system was going to be built to allow use of run-of-the-mill charging equipment, and that it’s cost would be less than $100.   It’s also going to be internet connected–we’ll be able to log state of charge, voltage, and a number of other performance metrics…

Here’s where things start to get pretty interesting–and where money really starts leaving never to be seen again.  I’ve talked briefly about the battery pack itself, and still plan to write more about that decision process, but it’s in-hand and looks well suited to do the job. That’s the easy part.  Now we’re into figuring…
