    starfleet posted a topic in Inverters
    Hi guys. Does anyone have any experience with upgrading the firmware of Uretech HPS 3K-24V hybrid inverter? It looks like a clone of Axpert Voltronic MKS 3K-24. WatchPower detects it as "Stand alone" Transformer with main CPU version 000SR.27. I know that newer build versions of this inverter are equipped with cold start option and other bugs fixed due newer firmware. But I was unable to find any firmware for this model or a way to flash it properly. The exact manufacturer is also unknown (there is a company in Turkey that sell these inverters but it isn't the only one). My particular model doesn't have cold start option and there are some issues with charging stopping prematurely or charging longer than it should. It's also really loud due fans working at full power during charging (even if charging power is low and it's not getting hot). I attached screenshots with detailed information about this inverter.
