    6 hours to get 2 x EG4-LifePower4 to talk to Solar-Assistant via RS485 to USB.

    If the screen-printing on the battery showed the mirror (ie 4 3 2 1) that would be a huge heads up and help, but it is the same 1 2 3 4 on all the batteries.... Of course, putting the 'on' in the correct location for the given battery BMS would be helpful as well. Yes, its a hot mess and...

    @thanhrodke I wish it was as black and white as that... but you have both upside down and left/right flip (and correct layout) Also since they don't seem to have a serial number record of which of the three switch options any given battery may be, its up to the user to figure it out for...

    Ah, yes, the 'old error 61... combined with 'who's feature set do I want'...... Here is the rub. I can't answer for you, but I can rough out my thought train..... My system is 100% off grid. Thats the first and important thing to know... only its not... I have built a hybrid system. I use the...

    My batteries came before my inverter, so I left inverter blank in SA and spent an hour or more trying to talk to the batteries from SA. Turns out you MUST have some inverter, any inverter, broken or missing inverter, configured in SA before it even tries to talk to the batteries. If you have...

    Oh, and you are not trying to talk to the batteries with two bits of software at the same time right? Those screenshots were taken at different times? (Just sanity checking here).

    Since you don't have the inverter plugged in, but you still have to configure it for the battery communications to work, SA is trying to poll two different devices out the one interface and that might be messing things up. Do you have a spare or second serial to USB device you can plug into the...

    Well, come on! Spill the beans! Flipped, revered, or both? Or perhaps the cable was wrong? It really is worth looking at the raw serial/modbusRTU data to see what SA is seeing. (But not decoding).

    Glad it helped @CCBA I am sooo soooo sooooooooo glad I stuck with SA and have it talking with the batteries. Its 'power' settings are a game changer for some systems vs what the inverter can do (ie, nothing). The data is amazing and borderline critical in tuning / setting up / commissioning a...

    Solar Assistant Wish list, Bugs and Issues.

    @chrismjspencer Yes. I am 100% off grid by choice, but you can clearly see in the screenshot from SA it shows what you are looking for. Monthly and yearly.

    Solar Assistant Wish list, Bugs and Issues.

    Dark Theme. Grafana supports a dark theme, why is it not a tick box option on Solar-Assistant? You can tweak the URL to get the dark theme, and that's what I have done, but the front dashboard takes around 15 CSS tweaks to get 'dark'. It really should be done right by the dev. You can also...

    I did wonder if that is the better method. I cant imagine the EG4 talking to the two batteries as well as Solar Assistant. Seems to be one or the other to me. I also want to use the SA battery curve rather than the inverter one, so again, leaning on your approach. Thanks for letting me know how...

    Bought two of these batteries and an EG4 6.5kw inverter from Signature Solar. The batteries arrived first, thought I would take the time between the two shipments to get the batteries talking. Battery 1. The On / Off markings on the switch are reversed. (Up is binary off). Battery 2. The On /...
