    Solis inverter charging battery from the mains

    Sure. It's already been out and checked and re-torqued to spec. I've spoken to my Sparky about it and he says the buzz doesn't mean the MCB is bad, it will still trip, more likely earlier rather than later. Plus, there is only the solar on this circuit so 5Kw charging (which I have never used...

    Solis inverter charging battery from the mains

    One thing I've found is that the inverter sometimes says 'done' but when you go back and check, it didn't. This may be related to the battery vendor you set in the inverter. I have a DIY battery with a Seplos BMS. On the BMS its set to 'Pylon' and on the inverter side it's set to 'Aobo'. Sorry...

    Solis Hybrid Inverter : Operation of backup circuit

    Thanks for your input. Something is misconfigured then... The inverter is in AUTO mode which should work as the manual describes under Scenario 2 which I copied above. In Scenario 1 of AUTO mode, PV supports normal loads, the excess solar charges the battery, and if theres more excess still...

    Solis Hybrid Inverter : Operation of backup circuit

    This has bit me in the ass today and I'm not happy. I just finished wiring in the backup AC circuit to my burglar alarm and internet routers etc, everything was working until the sun went down. Then the inverter went completely off and my 'critical loads' then shut down. Anyway - the manual...

    BYD BMS

    Are you sure? That's awfully high.

    Does the BMS have to be connected to the inverter?

    I basically just started ignoring it. After I changed some of the voltages so it would charge higher before it cut out. I need to revisit it but too many other things are grabbing my attention at the moment.

    Does the BMS have to be connected to the inverter?

    <je suis desole - long rant!> Hi, Yeah I think it's mostly working according to expectations. However, I had to re-flash the latest DSP firmware for it to start behaving itself, and several times I adjusted battery storage settings, but I am not sure which (if any) of those changes fixed it...

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    Yes, easy-peasy. Put your multimeter on continuity or diode-test (usually the same setting). Put the leads across the diode. One way will not register anything, the other way will register something, usually 0.7-ish. If you get nothing at all both ways, the diode is open (blown). if the diode is...

    @manuromero05 Are you going to fix your post?

    Did you ever top-balance the pack?

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    How did you do it? Was it automatic or did you use any of the 'calibrate' functions in Battery Monitor?

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    That's nice and a shame that the source isn't available. I'd like to build it and test it on ESP32 and perhaps make it a base for another project. I'm currently working on an RS485-Wifi Bridge using ESP32 so I can connect the inverter to the current monitor in the consumer unit without using a...

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    As @reklamos told me yesterday, Aobo on the Inverter, Sofar on the BMS. Works for me.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    RHI-(3-6)KW-48ES-5G The DSP version in that archive is v22, and the HMI (which is from me that Solis gave me yesterday) is v35. I have v25 of the DSP too, but I downgraded it to v22 because both I and @reklamos saw some issues.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    It's not connected to the internet. I did not purchase a wifi or gsm stick with the inverter.
