Re: Surge Protection Devices - Single Phase and Single Pole - WHY ?
It does depend on your local wiring standards. In North America, the neutral and green wire ground are connected together in the main panel neutral+ground bus bars. So, by itself, green wire ground a…2 · -
Re: Mixing 2x6v 210ah with 1x12v 130ah
MPPT and PWM controllers are not magic... Shaded solar panels (or dense cloud cover) just do not provide much energy. If one part of the array is in sun and another part in some sort of shade, wiring…1 · -
Re: Pump won't start on power from Inverter
It appears that your pump may have a VFD built in (Variable Frequency Drive). Many "simple" electronic power supplies with AC input use a pair of diodes and a high voltage capacitor to rect…1 · -
Re: Reducing start up current on air compressor for off grid
Does it look like you are getting a better starting/running current profile (soft start)? Watch the temperature of the electric motor... Most (some, many, most?) VFDs use square wave current of some …1 · -
Re: Reducing start up current on air compressor for off grid
You could also (possibly) use an NTC (negative temperature coefficient) resistor: Higher resistance when cold, Lower resistance when hot. http://www.newark.com/pdfs/techarticles/ametherm/Ametherm_PPT…1 ·
