Definite newbie here!
I have a 16 cell lifp4 battery and am wondering what is the best/safest(for the cells0/fastest way to top balance these cells?
I have a small power supply on which I can set the voltage (ie 3.6v) and the current with the cells in parallel but it takes a very long time to...
My Growatt SPF 6000T DVM is repetitively shutting off solar input, beeping and then trying again. Seems to happen when the battery voltage gets to about 55.8V,100% SOC on my lifepo pack. I have all the parameters set using the recommended settings and I can't get it to stop this behavor. I am...
I am still trying to communicate with my JK-PB1A16S10P bms with no luck so far.
I am using a USB to Ethernet dongle but the computer (JK software) does not recognise it as a com port.
Which dongle should I be using frm the com board of the BMS to the computer?
Thanks
I seem to need some help on two fronts with my eg4 6000xp setup.
1. When trying to use the screen on the unit I find there is no instruction on when to use the RETURN KEY and what it does??? Second, when I get to item 14, I don't seem to be able to move on to item 15. How do I do this?
2...
Is there any connection between my Growatt 6K (48V LFP) showing error 3 (battery voltage too high at 55V) and the fact the the 100A fuse from the battery to the inverter just blew? Is there a Growatt setting that I should change?
Trying to wire the ac input and output and am replacing my Growatt with the 6000xp. Coming from my main panel to the inverter I have three conductors: Black, White and ground (bare copper) The voltage between gound and white is 120v and also between ground and black is 120v. On the growatt I...
With an all in one inverter one can choose the charging source (solar,utility) and set it to change at certain times.
With a stand alone charge controller it looks like charging can only use solar as a source.
Is this correct? Or ar there variations on this idea?
I am considering an mpp LV6048 but have questions concerning the AC input which is specified as being 120vac.
In the attached diagrams from the manual. it looks like two 120 lines 180 degrees out of phase are needed but wouldn't that be 240v AC input.
It seems to me that I can get L1 and L2...
I do not see anywhere in the manual about pre-charging the caps in the inverter? Is this recommended anyway or should I ignor precharging? If I do pre-charge, how is that done? What needs to be turned on during the pre-charge? Just the battery circuit?
The default setting in the inverter is...
I am looking at a Growatt Inverter with a 250V input limit from the PV's. First question: What happens if this is exceeded? Does the inverter shut itself down?
Second question: The power is 6kW. What happens when when PV's of more than 6kW are connected to it? ie more than 24A capability?
Thanks
This unit comes with a small plug that can be plugged onto the board and has 4 green wires tied to a single ring terminal, a red wire nd a black wire. Thee are thin wires, intended for low loads or data signals.
Where do these wires go? What are they connected to? What are they for?
Thanks.
Can anyone use this 8s balancer delivered to me by mistake and the seller does not want the return.
This unit is brand new and unused.
Just let me know if you are interested.
Why are these breakers: https://www.invertersupply.com/index.php?main_page=product_info&products_id=199121&gclid=CjwKCAjwgISIBhBfEiwALE19SbQPFYAYktg545bwV3VdjZRROPCVyezZ9RwIiSNnexKboaMJIe48RBoCifYQAvD_BwE
NOT recommended for solar applications? What is it that is the problem in using them for a...
Setup#12 says" Voltage point back to utility source when using "SBU" mode.
I have 48V LIP pack, currently at 53V. The suggested setting for #12 is 46.0V. Does this mean that when my battery drops to 46V then the utility will be used to drive the loads? Does it then start charging the battery...
In my Notices on the PC app I am seeing events such as:
PV Isolation low
EPS Over load
Battery open
What do these terms mean?
Also, I am finding, on my PC, that I must log in a couple of times each day and this is getting tiresome. Is there a way around this repetitive process?
Also, almost...
I have 16 250W USED panels (V(oc) about 35V, I(sc) about 6A) that I am hoping to connect to an MPP lv5048 along with 48v of battery.
Which arrangement of panels might work best for me. No shade to worry about.
Thanks
Does it matter whether one used solid or stranded wire of the correct guage to feed and return from the inverter? Stranded is easier to work with I believe in terms flexibility when routing it.
I am attaching three pics of data in my system.
The first shows a lack of data on the DATA tab and I am wondering what might have caused this? Also, Why do I have to keep logging in to the EG4 every day?Is there a way around this?
(2nd and 3rd ar connected)
The second shows that a small...
I have a 6 month old Split Phase SPF 6000T DVM Growatt Inverter that I have decommissioned. It simply stopped working with NO sign of physical or electrical damage on the inside or outside. It looks brand new! Would you be interested in having this, perhaps for repair/resale? I really don't...
I have a Growatt spf 6000 with 48V of LIP batteries using an overkill bms.
There are times during very good sunlight that the solar PV input will shut down showing no connection from the panels on the Growatt screen and registering zero amperage coming in.
Does anyone know what setting on the...
The attached screen shot shows my solar power (in yellow) dropping to zero around midday in Full Sun. I am sure I have some settings wrong. I would like, somehow, to use solar to charge the 48v LiFePO battery and then help with load so that solar s always being collected and used. Also, the...
I just received my cells from China and all read 3.28 or 3,29 volts except for one that reads about .2 Volts. Do I try charging this one cell before starting to balance all of them. What charging voltage and current is recommended for such 200ah cells? Advice welcome on how to be sure that...
My Overkill 48V BMS shut down the system today and I suspect the delta of the cell voltages did it.
Does anyone know what the cut off is for the delta between the low cell and any particular cell? Can this be set in the BMS to suit my needs?
I have an SPF 6000T DVM Growatt with Solar assistant monitoring the data from the inverter and the Overkill BMS on a 16s LFP system.
The LOAD DATA has stopped showing on Solar Assistant nd I cannot see why it would have quit showing that data.
Any ideas are welcome.
Thanks.
does anyone have an EG4 6000XP Off-Grid Inverter | 8000W PV Input | 6000W Output | 480V VOC Input | 48V 120/240V Split Phase | All-In-One Solar Inverter running with Solar Assistant successfully? Do the two play nicely together? Thanks
I just receved mine and I find that the first of the 4 cell sensor plugs is missing the wire for B0 (Battery Negative). As a result the app is not recognizing cell1.
Should the B0 pin on the bms be connected to Battery Negative? Is it on yours?
Thanks,
Dave
This morning my 6000xp is offline. How do I get it back online. Tried unpluggin and plugging in he wifi dongle but only one green light shows on it and it is not online. The display is actve.
Thanks for an advice.
Just installed a 6000xp and already had Solar Assistant but I can't get them to talk to each other.
I think this is a network issue that I need to learn about.
Here are the symptoms;
The 6000xp web app shows everything well using my browser and logging in.
Both the 6000xp and Solar Assistant...
