Hello wrenches,<div><br></div><div>Its been a while since I posed a question about this, but I thought I'd follow up. I got a chance to get a scope on the propane generator output. The voltage output of the propane generator has a significant "bite" out of the top of the voltage peak. Jay, I think you were right, the rms voltage was good, but the peak didn't match up with what the Heart inverter wanted to see.</div>
<div><br></div><div>Does anyone know what may cause a "bite" in the top of the voltage waveform of a generator?</div><div><br></div><div>Thanks<br><br><div class="gmail_quote">On Sat, Aug 18, 2012 at 8:23 AM, Jay Peltz <span dir="ltr"><<a href="mailto:jay@asis.com" target="_blank">jay@asis.com</a>></span> wrote:<br>
