Hello everyone! I've an Easun SMX-II-3.6kW inverter and I think it's defective (maybe my fault IDK). I've updated the fw to the 6.67 version, I got it from the seller. This version has the ability to mix the AC IN and the PV IN to the load (not only for charging) but my device is making trouble in my grid, my UPS next to it is buzzing like hell - the transformer is resonating horribly. We measured the inputs and outputs and it is backfeeding or incorrectly mixing the PV and AC when the battery is full. (During charging mode it works good, it charges the battery at 10A (100Ah batt.) as I configured but then when the battery's full it starts to send current from the battery (10A) to somewhere (at the input there is 2+ ampers, 60W lamp at the load nothing more). So I want to downgrade the firmware to 6.63, it was the factory version, maybe it lacks the mixed load feature.
Anybody knows where to download (old) firmwares for the device?
Thanks,
