What I found is a Sunny Island mini-grid system behaving oddly. The generator, when started with the SI, would run for a few minutes and then shut down. Further investigation revealed that the SIs were indicating that the inverters were sending lots of power back to the generator, even with the Sunny Boy turned off. <o:p></o:p></span></div><div style="font-size: 11pt; margin-top: 0in; margin-right: 0in; margin-bottom: 0pt; margin-left: 0in; font-family: Calibri, sans-serif; "><span style="font-size: 12pt; font-family: Arial, sans-serif; "><o:p> </o:p></span></div><div style="font-size: 11pt; margin-top: 0in; margin-right: 0in; margin-bottom: 0pt; margin-left: 0in; font-family: Calibri, sans-serif; "><span style="font-size: 12pt; font-family: Arial, sans-serif; ">I don’t know if this was actually the case, nor can I grasp how this could happen.
