Inverters Stacked

[davidbrady]

Hey Al,

He's talking about the battery DC voltage stiffening capacitors. They're aluminum electrolytic and the Trace SW4024 uses 23,400 micro-farad of these things! These types of caps have self-healing properties. They can break down when left on the shelf for prolonged periods of time which results in high leakage current when first turned on. The more they're used the more they heal and return to normal functioning. I never turn my inverters off. These are industrial units built to work for 24x7 for 15 to 20 years.

My power board design removes the caps from the power board and places them on their own capacitor bank PCB - as seen in this post. This way, if the capacitors ever fail it's a very simple swap out to new.
