    Rosen Battery with Growatt SPF 5000ES (BMS ERROR)

    Ok what have you set the charging voltages to in setting 19-21? Are you paralleling the two inverters or seperate systems?

    Rosen Battery with Growatt SPF 5000ES (BMS ERROR)

    I’m sure I can help but not understanding the full issue. Need some more info but it sounds like you are overcharging the batteries to an over voltage level which would shut them down as well as the inverter. Which Rosen battery do you have as in the model number? Is it 15c or 16c? Is it power...

    Rosen Battery with Growatt SPF 5000ES (BMS ERROR)

    I run growatt and Rosen batteries. Took about two weeks to settle down but I have all communication working well and everything is perfect except for the annoying transformer noise caused from it being an all in one. But they work great and I didn’t buy my Growatt from them. Bought it from...

    hi guys BEEEP. sorry about that BEEEEEP

    Question do you find your spf6000 fan very VERY noisy and constant reguardless of load? I’m running at average 650w even at night and the fans are really very noisy. I’m wondering if something is wrong or what? It may stop for about 2min at times or a min and then just start at full fan speed as...

    Growatt - Odd behavior

    Speaking about the idle consumption, do you guys know of an inverter that makes a lot less noise than the growatt transformer base inverters? I have a SPF6000DVM and it is LOUD.

    Growatt SOC calculation settings -Shineserver

    Not really . My lifepo4 are 15 s so nominal is 3.4x15 which is 51 at highest. His is 3.4 which is. 48 at highest so charging at 57 is really ridiculous that why he will never see past 57v and 75% SOC . Figures are too high if it is really a 14s

    Growatt SOC calculation settings -Shineserver

    Firstly , How do you get 57v with a 48 v 14s setup? That’s 57/14=4.07v per cell which should shut down the batteries passing 3.65v? Any way that said there doesn’t seem to be a rebulk feature on the growatt so I can only tell you what I do which is to use one of my Outback fm80’s with some...

    How to run AC input off generator only with 2 Growatt 5000es inverters and auto transformer…

    I have an old Honda 6000 generator that works perfectly . It is not an inverter generator . Can this be connected to Growatt Spf6000dvm? What are the specifications for a generator to be used on the growatt if there are any? Any assistance needed

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

    Yup. I got three battery packs from Rosen and two of the seplos failed due to the bad diode and they sent me all replacement and even a spare for the third unit.

    Question on charging LiFePO4 to 90% SOC with a charger in an RV

    Guys I have a Spf6000dvm with 4875w ( 325w Canadian solar x15) panels directly connected to the pv input so the internal charge controller is producing at max the 79 amps to charge batteries. I have 3x (48v 200ah) Rosen lifepo4 battery banks ( roughly 30kw). On cloudy and over cast days charging...

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

    What does “ SOL with a CAN board”? Link just told me the bird I have is RS485 even though it says Canbus. Need some clarification with you guys experience.

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

    Ok so what you guys are saying is that even though the port on the boards are labelled canbus/rs485 they do not support them both on the same board? I have spoken to Link at Seplos and I really only tried Can communication and it works with my Rosen batteries

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

    Seplos can use can or rs485. Just a different configuration for the cable. Same port. It’s labelled can/rs485

    Growatt SPH4600 - SEPLOS 200A 16S BMS

    Can you explain this more? How could you ever use a regular patch cable that is standard Lu straight thru to get communication ? Only unless it’s a standard cross over cable then I may get it but not a regular straight they patch cable

    No . It works with others as long as bms is compatible ex Rosen batteries work .
