    Harmdor got a reaction from mzezman in Deye Cloud   
    A few years ago I registered my Deye 8kW on Solarman, which was new to me at the time and was quite disappointing.
    I was used to the monitor for Victron.
    Later I installed a micro inverter and wanted to connect it to Solarman: impossible.
    So registered on Deye cloud: works perfectly. With a micro on the gen port of the Deye hybrid, Solarman no longer knew how it should be displayed.
    The micro is not seen as PV generation.
    I also coupled the hybride to deye cloud.
    Even more misery came along and then I switched to Solar Assistant: more than great.
    You can even connect a local screen and mouse so that you can live completely without internet: no one can interfere with your settings and you can program your inverter at all times.

    @Mercadian
    Consider these facts before deciding to run the generator into your expensive inverter setup.
    If a portable generator( normally tubular frame without or on wheels) is used the chances is very good that it is illegal to connect to the db board as these generators are V0V winding configuration. Even connecting these type generators through a transfer switch it is still illegal. The reason being you will always have a floating neutral even when using an earth spike.
    SANS 10142-1 states in clause 7.12.2.7 that a 230 V generator with a V-O-V earth connection (centre tap on winding which is earthed) shall
    not be connected to a fixed electrical installation. Such a generator may only be used as a free-standing unit to provide power to specific appliances.
    Portable generators produce "dirty power" with THD of between 8-30% where the industry standard should be <5%.
    It is not just voltage and frequency we should look at when deciding on generator connection to inverters but also the quality of the sine wave we push in.
    As a rule i would not install any petrol generator to business premises or domestic environment unless it consist of TN-S earthing arrangement nor would i supply a COC.
    I will however recommend diesel generators twice the output of the inverter to be installed.
