<div dir="auto"><div>The only issue I've had was with a high end induction range shutting down when the battery inverters frequency shifted to control some AC-coupled PV inverters. After some testing, it became clear that the induction range was fine up to 63.0 Hz, and would immediately shut down at 63.1 Hz. Programming the battery inverters to top out at 62.5Hz solved the problem.</div><div dir="auto"><br></div><div dir="auto">Blake</div><div><br></div><div data-smartmail="gmail_signature"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div><span style="color:rgb(136,136,136)"><br></span></div><div><div dir="ltr" style="color:rgb(136,136,136)"><div dir="ltr"></div></div><span><p dir="ltr" style="line-height:1.38;margin-top:12pt;margin-bottom:12pt"><span style="font-size:12pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;font-weight:700;vertical-align:baseline;white-space:pre-wrap">Blake Gleason, PE | Employee Owner</span><span style="font-size:12pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;font-weight:700;vertical-align:baseline;white-space:pre-wrap"><br></span><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;vertical-align:baseline;white-space:pre-wrap">Director of Innovation and Technical Excellence<br></span><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;vertical-align:baseline;white-space:pre-wrap">O: 510-845-2997 x128</span><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;vertical-align:baseline;white-space:pre-wrap"><br></span><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;vertical-align:baseline;white-space:pre-wrap">C: 510-867-5878</span></p><div style="color:rgb(34,34,34)"><font color="#000000" face="arial, sans-serif"><a href="http://sunlightandpower.com/" style="color:rgb(17,85,204)" target="_blank"><img width="211" height="109" src="https://ci3.googleusercontent.com/mail-sig/AIorK4yjk0tWxLYJdmm8ixByIvVlZ8qHwp7MBdjlqQNVO7hj39UcwfDd-aKPNU5cBLNHLCKqOqC-w-9FROD8" alt="sunlightandpower.com" style="margin-right:0px"></a><br></font></div><div style="color:rgb(34,34,34)"><font face="arial, sans-serif"><br></font></div><div style="color:rgb(34,34,34)"><font face="arial, sans-serif"><a href="https://linktr.ee/SLP_Socials" style="color:rgb(17,85,204)" target="_blank"><img width="152" height="28" src="https://ci3.googleusercontent.com/mail-sig/AIorK4wmYY0xXFzX-5yuRXvlOjP9uoFrUg4y1unXDQvTBQr5HVpFDvICelbuEoFiS7A5OgrP9l9BZg76XfMB" style="margin-right:0px"></a><br></font></div><div style="color:rgb(34,34,34)"><font face="arial, sans-serif"><br></font></div><div style="color:rgb(34,34,34)"><font color="#000000" face="arial, sans-serif">1035 Folger Ave.</font></div><div style="color:rgb(34,34,34)"><font color="#000000" face="arial, sans-serif">Berkeley, CA 94710</font></div><div style="color:rgb(34,34,34)"><a href="http://www.sunlightandpower.com/" style="color:rgb(17,85,204)" target="_blank"><font face="arial, sans-serif">www.sunlightandpower.com</font></a></div><div style="color:rgb(34,34,34)"><font color="#000000" face="arial, sans-serif">License #326203</font></div><div style="color:rgb(34,34,34)"><font face="arial, sans-serif"><br></font></div><p dir="ltr" style="line-height:1.38;margin-top:12pt;margin-bottom:12pt"><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;vertical-align:baseline"></span></p><div style="color:rgb(34,34,34)"><font face="arial, sans-serif"><a href="https://benefitcorporationsforgood.com/" style="color:rgb(17,85,204)" target="_blank"><img width="75" height="75" src="https://ci3.googleusercontent.com/mail-sig/AIorK4zNQnLwwA2Gfw-r6Z26JjX-0mPWU3DAfpN9q1TYxOilMCJROy3kEKcfAW6arJoJ3mxp0vPD6WZUXCcN" style="margin-right:0px"></a> <a href="https://www.amicussolar.com/" style="color:rgb(17,85,204)" target="_blank"><img width="107" height="64" src="https://ci3.googleusercontent.com/mail-sig/AIorK4zKriewlV0wT2ND5dRYfEXBEecnnLnjY2QJld2uXi95WOSRJxqD2atMe60r9ESy-AUZZYDJf3YzW989" alt="https://www.amicussolar.com/" style="margin-right:0px"></a> <a href="https://calssa.org/" style="color:rgb(17,85,204)" target="_blank"><img width="136" height="45" src="https://ci3.googleusercontent.com/mail-sig/AIorK4x_pi6qJbETKHrniRlikSghWRw1ZhF64UNkTmIpyZYVyu2Ls_JzgxRzHy5a9IO1D0EbbBDqpWeKLVRe" alt="https://calssa.org/" style="margin-right:0px"></a></font></div></span></div></div></div></div></div></div></div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Mon, Jun 30, 2025, 8:18 PM Chris Sparadeo via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto">Jason,</div><div dir="auto"><br></div><div dir="auto">I’ve installed several Sol-Ark inverters in off-grid applications with induction cooktops and have had zero issue.

I actually have off grid customers with induction, uses much less energy and with outback have had no issues, on whole home backed up loads with solark, again no issues, I can't say how much it is used in an outage but it does work.<br>
