Thanks, I have adjusted the bulk and float as suggested. Time will tell

Thanks for your input, I put the battery specs in the thread.

It's a LifeP04 battery, I raised the voltages a couple days ago to see if I could get the battery to charge some more but so far I haven't seen any increase in overall charge. Maybe because it's switching back to battery as soon as it reaches 50V. I have set bulk to 51.8V and float to 50.6...

Thanks, I raised it a bit and I will monitor it. I don't think it's normal, flashing red lights and error codes make me wonder what's wrong. Anyway, thanks to you guys on this Forum, the Growatt finally seems to be working ok. I need some more battery and probably some more panels to make...

Thanks for your reply. Do you have any suggestions? I am thinking raise the voltage that the inverter goes back to the grid at, I don't want to hurt the battery.

Hi All I think I am finally getting my Growatt SPF6000T DVM with 48V 15S Rosen battery to run half-decent but I have one issue that I find a little confusing. At night while I am on the battery and even after the inverter switches back to the grid I get warning code 04(Battery Voltage...

Very interesting, thanks for sharing. I wonder if it will work with LifeP04 also.

I bought a complete system from Rosen, including a Growatt SPF6000T DVM and a 48V 15S Rosen 200 AH Lifepo4 battery. The manual says communication works with RS485 but it only works with CAN and then it doesn't seem to work for too long. At first Rosen's support was fairly ok but then they...

Sorry, I don't know the part numbers. The technician changed the relays but I will try to find out.

Hi everyone, I thought I had responded to this already. FYI it was the relays that connect the PV input to the charge controller board. Once the relays were changed everything was fine. I am not sure what caused the error but there was a time when the bms was shutting on and off the panels a...

Sorry for the late reply, the notification went in my junk mail. Anyway, that wasn't the problem, it seems like the charge controller has burned out. I don't know why but I need to get a new one. Thanks

Thanks for the reply, but that did not work. Is there any way to check if the charge controller is working?

Thanks for the reply, can you spell it out in a little more detail, please. I have turned it off and on a few times before. What order should I turn things on in? I am still new to this.

Hi All, I need some help, please. My Growatt SPF6000T-DVM is not seeing the panels. There are no panels displayed on the LCD screen and it is not charging form solar. According to the voltmeter there is 134v going to the pv input terminals. This has been the reading from the beginning. It...

Thanks

ok, I am not sure how to tell if one LED lamp is better than the other. Just trial and error? When you say inverter wires, you mean the wiring inside the inverter or the output wires from the inverter. I am usiing #4 wire to and from the inverter. Right now I only have one battery, so it's...

Thanks, I will try USE and see if there is any difference. I think I have gotten rid of my fault codes and error since I adjusted the voltages. My last remaining problem which might be a little more difficult to get rid of, is that when I have my inverter on SBU, after the sun goes down...

I was watching the battery when the microwave came on and the draw was over 30 Amps. When I first got the battery, before my loads were balanced, the microwave used to often cause overload faults and shut down the inverter. 960watts doesn't sound like a lot, if I had double the battery would I...

The alarms can be turned off in program 15 and program 17. I just think it's good to know when something is not right.

Thanks for the insight, I might very well be drawing more than 20A. What is the best way to check the current draw? There is an indicator on the battery which tells you how much current is being discharged, I will have to pay more attention to it. Is there a way to tell if the cells in your...

I bought my Growatt from them and I'm having the same problems. I already replaced the BMS but it's still not working right. I am thinking of using a different kind of BMS because the one in the Rosen battery doesn't seem to be working properly. Any suggestions? I have heard good things...

This sounds a lot like what is happening to me. I am using a Growatt SPF6000T with a Rosen 10kw 200AH 15S battery. I was using the Lithium setting and connecting the battery via CAN L52 but the inverter would switch back to the grid relatively quickly and when I checked the SOC on the...

Thanks, the manual is not that clear.

I am new to this but I have the same inverter and I had the same problem. I kept getting an overcharge error/fault (03). After the battery got full, I would get the beeping and the over voltage error and the panels would get disconnected from the battery, and the cycle would keep repeating...

US2 is recommended when using lithium batteries without the communication cable.............according to the manual.

I don't think disabling the beep is the answer. The question is why is it beeping and what error code/fault are you getting?

Hello, where did you download the firmware and how do you know if you have the latest firmware or not? I am still struggling with my Growatt SPF6000T DVM.

I have the exact same inverter with a 48V Rosen 10kw battery, and as someone that is new to this, I found it a bit tricky to set up. I am not using communication right now but when I was using it, I put one end of the cable in the BMS port on the inverter and the other one in the CAN port of...
