EDMS from Felicity, you can contact them to give you it.

Hello dears, I am importing Felicity LPBA 48V 170 Ah 16s1p LiFePo4 battery which defined to be CATL grade A cells from China. unfortunately 1 battery I installed it for my sister's house after it gets fully charged from utility for example and restrd long time on around 54v but stops charging...

I monitored the battery many time, the configurations is 56.4V for float and bulk charge parameters, but no times it exceeded the range of 55V so it stops around this voltage. now I connected the Battery BMS to the monitor software on the PC, and wait until the BMS stops charging and battery...

intresting information, but if the bms stops charging before the battery get fully charged, how to force it to charge and see how much the cells are balanced?

thanks Bobert, I connected 3 days ago the BMS to the pc monitor and I see the 16 cells are 100% balanced with 2 digits, so all was 3.34*v. the cycles counter after 2 weeks of usage was 4 cycles only. the battery seems to give the expected energy capacity but I will do capacity test by the...

Hello guys, I installed many solar systems ladt months all were Felicity inverter 5kw and Felicity LiFePo4 battery LPBA48170 which is 170Ah 51.2V, CATL grade A cells 6000 Cycles. Ihave installed 2 systems last week in the same building for 2 different apartments. i connected them to the...

hello, the charger gives 15 point something at open and when I connected it to the battery it drops to 14.2 or 3 I think, and increase with time to limits 14.8 or 9 also I think. I called the middle east agent today and yhey asked me to carry them to the local dealer I don't know what they...

hello everybody, how much we can compute the energy stored in a battery if we register the instantaneous power (charging voltage and current) over time, so for example a batteries of 200Ah takes 20 hours to be fully charged with 10A charging current. can we estimate the energy stored by...

hello I charged the 3 batteries sometimes each one individual and sometimes 2 in parallel, currently lowest gravity is around 1.200 sometimes I read 1.175 if I flip and turn the hydrometer I see some variation in float glass position. but your are saying charge each until current drops under...

hello, thanks for the fruitful information. ok but in my case the one the hasn't been discharged gives a voltage of 13.07V and gravity of 1.250 and that is after after connecting and charging them together in series. but the 3 others batteries are in the red region even if their voltage is...

I knew that connect the 4 batteries in series when they are in different states of charge is a bad idea but is it such dagerous or destructive? i charged a single battery with 15A old tranformator based charged, it was already 13.07V just after disconnect the inverter so during the charging...

welcome and thanks in advance. I freed up the all system (4860w panels) and the sunny days last week 3 days even if I saw the charging current before noon is 20A and after noon is limited to zero also even if utility is available which indicates that charging has been almost finished due to low...

Hello everybody, I have bought 4 200Ah 12V tubular flooded lead acid batteries for my 5kw hybrid solar system 3 weeks ago. Unfortunately I got bad batteries performance in term of capacity even if they are "fully charged" as the the Must inverter PH18 Plus showing on the display and user...

thanks a lot @sunshine_eggo for your reply. I am with you about the inverter. are you available for a discussion here about to tell you what I did and what happened?

Hello everybody, 6 weeks ago I installed my solar system 12 panels 405w from Trinasolar with Must hybrid inverter 5000W 48V (PH18-5048 Plus) , I used it for around 4 weeks without batteries, actually with 4 damaged car battery that give voltage without amperage just because the inverter could...

no one could help?? ??

Hello everybody, I have a 5kw off grid inverter (Must PH18-5048 Plus) with 4 Tubular deep cycle 200Ah (Maxma TAF C20 200Ah by Luminous). could please you help me in configuring the charge controller for best performance while preserving a long life battery cycle. currently I am using the...

hello, the battery is flooded tall tubular, attached is its datasheet. what has made me confused is the vertical axis ticks of the status of charge characteristic in the last page of datasheet. you are right 46.6V supposed to be 0% or totally discharged. please see the battery datasheet.

Hello guys, please could anyone help me in selecting the voltage values correspond to 50% DoD, 60% DoD and 70% DoD? I recently bought 4 tubular 200Ah tall tubular Maxma batteries (Indian), and my Hybrid inverter (Must PH18-5048 Plus) is configured to as the attached figure shows, in addition I...

no fuse not.

in addition, 381W of these 3818W were coming from the battery.

ok but could the inverter take from these 4860w more than 4000w? in reality I am not feeling comfortable with this inverter because that I ordered a Felicity IVEM5048 hybrid inverter with the Felicity Lifepo4 48200 battery. this inverter is compatible with their battery plus it can take 6000w...

today it was around 28 degrees celius. is it realistic that panels give just 0.4A in short circuit where the sun light hits them from that angle ( around an hour before sunset)??

the difference in voltage between the combiner bow output and after the one thick cable was around 7 or 8 volts, but after I doubled the cable the difference reduced to 3V. this was my combiner box when they were 3s4p. it is still the same box but now 2s6p.is there any problem in using like...

please note that my inverter (Must PH18-5048 Plus) is 4000w maximum PV input power, and 5000w output power is 78.6% from 5000 or 4000w?

Hello again, I did what you have suggested, I finished reconnecting the panels in string of twos in series at 11.00 AM. between 12, 30 PM and 13,00. the figure below was the status of the inverter. I turned on 2 water heater (1200 Watts each) + 1 heater (800 Watt) and 3 refrigerators and a 60...

Thanks a lot, So the first thing I am going to do is to re-arrange or rewire the panels, 6 strings of 2 in series. just a modest question, why we are comparing the VOC or 3 in series (152.4V) to the PV array MPPT voltage (64-130V) not to the maximum PV array open circuit voltage which is 145V...

Hello all, any comment it will be helpful so I appreciate it, please help me. Regards

Hello and thanks a lot for your declaration. I hope I can feed all the information that you asked about. first thing i will attach a screenshot of the Must PH18-5048 Plus specification. it is a hybrid MPPT charge controller. see attached the specifications. I am living in Lebanon, the best...

Hello everybody I am something confused about the max power that should be taken from 4860w panels (12 * 405w and each 3 panels are in serie so 4 string). these panels feed the MUST PH18-5048 Plus inverter throught 8mm square copper cable. the maximum power that I have taken during sunny day...

Hello everybody please could you suggest me a good quality adequate price on AliEpress to buy lifepo4 cells and BMS to build my own Lithium battery because it is something hard to buy a ready battery from AliBaba (Shipping Lithium regulations) ? is it ok to use it with my Must PH18-5048 Plus...

I still have not bought batteries yet, I am using a collection of different sizes, different kinds, and different ages of old used cars an generators batteries to benefit from the day light energy untill I find the optimal batteries bank, is there any problem in that method?

owhh, really? so I could safe sleep now? I took 500w from my 5000w system but unfortunately we still didn't enter the winter season yet. how the winters and rainy days will be?

ops. :) so virtually no one could rely on totally off grid system in like our and you country. this was our sky today.

so if I bought the PH18-5048 PRO instead of PLUS which could work without batteries, what happens if the sky is something cloudy as my case? is it logic to take some hundreds watt only from 12 panel of 400w?
