Harbor Freight? 4 kW into a 4 kW charger? What's the altitude? I believe that 4 kW generator is actually only 3.5 kW continuous rated. By the time you derate for altitude, and then account for the generator not being built to be a prime power unit, its probably reasonable to derate it 50%. Then yet another thing, those gennies are 240/120 so you only get half the rated power at 120 vac, and it unbalances the load on the generator. Is that Conext 240/ 120 or just 120vac ? <o:p></o:p></p><p>Its just going to be a head ache for everyone until they buy something much better. They really need something in the 6.5 kW to 9 kW range, and 240 to 120 transformer if the Conext is not the 240/120 model, so that the generator is loaded evenly. <o:p></o:p></p><pre>Ray Walters<o:p></o:p></pre><pre>Remote Solar<o:p></o:p></pre><pre>303 505-8760<o:p></o:p></pre><div><p class=MsoNormal>On 12/15/20 1:57 PM, Sindelar Solar wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p>Dave,<o:p></o:p></p><p>I would first suspect the generator, not the inverter. Check its output voltage and Hz under load. If it's overloading, either (or both) voltage and frequency will drop below the acceptable range and the inverter will unlatch its input relays, wait for a bit, relatch and ramp up input amps until it again overloads and the cycle repeats. You may reduce either (or both) charging amps and overall input amps, broaden the frequency and minimum voltage acceptance ranges (I don't recommend this), adjust the AC output voltage of the generator, or advise them to get a better gennie.<o:p></o:p></p><p>Allan<o:p></o:p></p><div><p class=MsoNormal>On 12/15/2020 11:14 AM, Dave Tedeyan wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><div><p class=MsoNormal>Hi All, <o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I am going to service a system where the homeowner is telling me that their Conext SW4048 had been working fine for 14 months, and then all of a sudden recently stopped being able to charge the batteries from the generator.
