Seeing some posts about using a resistor to pre-charge (the capacitors?) the inverter. I have an MPP 2424LV-MSD that I hope to have batteries for in the next few days. I have seen lots of differing opinions on the subject. I read in one place that if the inverter is small, under 3000 watts was...
Introduction to terms In AC circuits, the current absorbed by a load can be represented by two components: active component I R and reactive component I Q. The active component I R, in phase with the supply voltage, is directly related to the output (and therefore to the part of electric energy converted into energy of different types: …
