They need to be in good condition and fully discharged. Max charge amps will occur only briefly then the charge rate will start to taper. Your charging settings need to be correct including temperature compensation. Any other charge inputs need to be disabled during testing, such as solar, wind or hydro. </span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d">Check for THD on the generator output. If the waveform deviates much from sinusoidal the inherent power will be reduced. Radians have been known to instigate high THD rates on generator feeds during charging, especially in Generator input mode. Trying the Support mode is good advice. </span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d">(We had <a href="https://millersolar.com/MillerSolar/case_studies/25_GFI%20Tripping/GFI_Tripping.html">this case</a> a while back.

We are having some with charging from the generator, as the generator charging seems to be limited to about 4500Watts +/- (20amps AC) when charging through the Radian. It is a Kohler 8.5RES generator and we have the AC input limit set to 30amps and the Gen input set to 30amps. The house load is only about 200Watts when we are charging. The system is at 2200ft of elevation, but I don’t know if that makes enough of a difference.</p></div><div><p class="MsoNormal">The Gen output voltage seems pretty good and holds around 234V-236V while charging.</p></div><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">Any thoughts as to why it may be limiting would be appreciated.</p></div><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">Thanks,</p></div><div><p class="MsoNormal">Amos</p><div><p class="MsoNormal"><img border="0" width="113" height="59" id="_x0035_CC32611-8A5B-4A47-87A2-F9960470DCBE" src="cid:image001.jpg@01DA0768.64B46C70"><span style="font-size:9.0pt;font-family:"Helvetica","sans-serif";color:black"><br><br> Amos Post<br> Integrity Energy<br> W 802.763.7023<br> C 802.291.2188<br> </span><a href="http://www.ienergyvt.com"><span style="font-size:9.0pt;font-family:"Helvetica","sans-serif";color:black;text-decoration:none">ienergyVT.com</span></a></p><div><p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Helvetica","sans-serif";color:black"> <a href="https://www.facebook.com/integrityenergyllp?ref=hl">Facebook</a></span></p></div></div><p class="MsoNormal"> </p></div></div></body></html>
