  1. Growatt SPF 5000TL HVM-WPV HUBBLE AM2 Compatibility

    KjA posted a topic in Questions & Answers?
    I can find plenty of info for Growatt ES Inverter and Hubble comms but not TL. Cannot get AM2 and TL to communicate. I believe the cable pins are correct but cannot find correct setting 5/36 information. If I try the settings for ES models, the system throws a low voltage error after about 10 seconds, and disconnects. I have a totally off grid system.

  3. Growatt SPF 5000TL HVM-WPV Does not switch over to SBU

    KjA replied to SamSA's topic in Inverters
    I have 2 SPF5000TL HVM-WPV inverters in parallel. 16 panels to each inverter. Fully off grid. As soon as the panels become active in the morning battery capacity drops instantly to 10% until solar output equals demand, at which point capacity restores to pre dawn value. The same occurs in reverse at the end of the day when solar output becomes less than demand. Once solar output is 0, the bat capacity restores to 100%. Any ideas why?
