Solar charged battery system providing electricity for audio system


Recommended Posts

Whole range of inverters that will go with the batteries, I would suspect the quality would vary as will price. Don't forget the battery is 400V d.c. so specialised market and specialised safety requirements in the design, creepage and clearance etc.

Also depending on the set up you are still connected to the mains due to feed through tariffs etc, or are in the UK. My mate had a power cur in the area and couldn't use his battery!

Its not the DC that's the problem its how you generate the AC, basically its a fixed frequency amplifier of 120V/60Hz with in this case a 400V input... So you need a source for your 60Hz, a nice sine wave, then how do you amplify it... Your 120Vs is about 170 peak so where does the excess go, or do you chop and reduce before the conversion to sine...

Its all this that can create noise.

How its designed is what makes the difference, multi layer heavy copper, buss bar designs with filtering are best...
