    How to connect Victron stuff for communication?

    No, not yet, I will be installing and connecting everything this weekend. That's why I needed to know how to connect everything.

    Thank you! That's always good! Great :-)

    How to connect Victron stuff for communication?

    Awesome @sunshine_eggo! Now THAT is helpful. Thank you so much 🙏 I assume the VE.Bus from unit 1 to VE.Bus of unit 2 to Cerbo VE.bus (2 total cables, "daisy chained") are 'normal' RJ45 ethernet cables? Like this: https://www.victronenergy.com/cables/rj45-utp-cable

    How to connect Victron stuff for communication?

    Hi guys, I've bought Victron equipment but I find it difficult to figure out how to connect all of them together for communication. I already asked this question in the Victron community, but all I get is a link to a document with some general information. So that's not helpful at all. My...

    Pylontech battery strange thing

    Thank you. The plus (+) IS at the top and the minus (-) IS at the bottom of the bars. Sorry, you can't see it in this picture. And the wires are the exact same length and there are no shunts or other fuses or so in between. How do you charge them independently to be the exact same voltage? Of...

    Pylontech battery strange thing

    Hi, I have 5 Pylontech US3000 batteries connected parallel. But the LEDS on the front show different values. The system (2 Growatts SPF5000ES) in parallel mode, charging this bank. No errors at all. What's the issue here?

    Oh really? Wow, where can I find more info about that? It would be a great opportunity ;-)

    2 Growatts 5000ES after reboot No Power Out

    I really like those, but I am in Europe (Spain) and afaik I can't get any EG4 stuff, unless I buy them for example at SS in the US. But even then. I don't know if they ship it to Europe and IF (big IF) they do, there are ridiculous shipping and import costs.

    2 Growatts 5000ES after reboot No Power Out

    That might be a good idea indeed. But I have no idea how to update the firmware on those Growatts. I will look into it.

    2 Growatts 5000ES after reboot No Power Out

    The thing is that I have these Growatts now almost one year and there have been several occasions that they stopped powering the house. Sometimes an error occurs and then instead of sending grid to the house, it completely stops and it leaved the house powerless. It's pretty frustrating when...

    2 Growatts 5000ES after reboot No Power Out

    It did the trick. Thank you! Apparently I have to switch on the Growatts one AFTER the other, while waiting for Growatt 1 tot finish booting. And THEN switch on Growatt 2. What I did was switching on Growatt 1, and after 2 seconds, switching on Growatt 2. I will explain below what I did, just...

    2 Growatts 5000ES after reboot No Power Out

    No, not tried that. To do that, I must reconfigure to single mode, instead of parallel mode. Or is there a smarter way to temporarily try just one.

    2 Growatts 5000ES after reboot No Power Out

    I've 2 Growatts 5000ES in parallel mode. After a full hard reboot (power off / total disconnect during the night because of heavy thunderstorm), both units were switched on again this morning and came up. Everything looks fine, except there is no power output. I don't hear the relays clicking...

    Anyone heard of Tensite LiFePO4?

    Hi guys, I'm still looking to replace my lead acid battery bank with LiFePO4 batteries. I live in Spain, so I cannot get EG4 batteries. But I found Tensite TS-L5000 batteries. Anyone familiar with this brand and/or this model? I have 2 Growatt SPF 5000ES inverters in parallel mode. They are...

    2 x Growatt SPF5000ES Parallel mode: weird situation

    Hi, thank you very much for explaining this. For Growatt #1 I can understand this. It's getting only ~150W from solar. But Growatt 2 is getting ~1584W from solar. The total load is just ~505W. In total there is more solar power than the load. In my logic, Growatt #2 is charging 1262W to the...

    2 x Growatt SPF5000ES Parallel mode: weird situation

    Hi guys, I have 2 Growatts SPF5000ES in single phase, parallel mode. Everything is connected in parallel, as the documentation explains. One single battery bank is connected to both Growatts, same cable length, etc. Growatt 1 has solar panels directed South Growatt 2 has solar panels directed...

    Solar Assistant with dual Inverters

    Ah, I see. And I got it working. I asked SA and got this response: :"In the configuration tab under Inverter, click disconnect, select both usb cables, click connect.". And that worked (with a regular USB cable). So problem solved. Thanks anyway for letting me "hijack" this topic for a short...

    Hi @timselectric, what is so special about this USB cable? I tried a normal USB printer cable, but it doesn't work.

    Solar Assistant with dual Inverters

    I have the same setup and same question, only with 2 Growatt inverters. I only see 1 inverter in SA. So I guess I need to connect the second Growatt inverter to the pi as well via USB. Question: is the USB cable from the inverter to the pi a normal USB cable? In other words: do regular USB...

    Growatt SPF5000 ES & LiFePO4 Compatibility

    Ah, thanks for the info. What exactly is 15s vs 16s? And I thought BMS is THE way to go :)

    Growatt SPF5000 ES & LiFePO4 Compatibility

    Hi, I'm looking for LiFePO4 batteries that are compatible with the Growatt SPF5000ES, AND are available in Spain.... I found Pylontech batteries, but I'm not sure if they are compatible. Any suggestions?

    Extend single Growatt solar system question

    Hmmm, okay. That means replacing the lead acid bank with the Lithiums... And then paralleling them. Thank you for clearing that up :)

    Extend single Growatt solar system question

    Hi guys, I have 1 Growatt SPF5000ES with 9 450 Watt solar panels and a lead acid battery bank. It works okay, but we need more power. So I bought 8 extra panels each 550 Watt plus an extra Growatt SPF 5000 ES. According to the Growatt documentation, I can parallel both Growatts, extending it...

    Growatt SPF5000 ES questions

    Just wanna check with you.... I drew this schematic on how I think it must be, based on what you said. Only question I have is, do I connect the contactor to the NC+C ports, or to the NO+C ports?

    Growatt SPF5000 ES questions

    @timselectric thanks for testing the @kirkdis scenario. Awesome! I will do that too :-). Do you use a relay as contactor? It's indeed an interesting solution. And @schmism , thanks for the calc. example. I understand it, however, I WISH I had 6-8hrs. Instead I have just a few MINUTES. So I'm...

    Growatt SPF5000 ES questions

    "You will never draw from the battery. Unless the grid goes down." Pfff, so SUB mode is also not what I want. I DO want to use solar first, then battery, and when battery is at 50% and sun is gone, switch to grid. That's why I chose SBU in the first place. But when the sun is up, I get what you...

    Okay guys, I have changed SBU to SUB and I have reset the values in program 12 and 13 to their default values. This is what I see now... I think we're getting somewhere :-) Let's see how it goes....

    Growatt SPF5000 ES questions

    Solar is generating enough power for the house. The house needs 473 Watts and solar is generating 1689 Watts. But still the 473 watts for the house is taken from the grid. (see AC BYPASS mode) I also notice that BAT. FIRST is showing. Don't know where that comes from. Shouldn't this be "LOADS...
