Is anyone familiar with the shop in link below, and if so, what is the service like? https://thepowerstore.co.za/products/pylon-up5000-4-8kwh-li-ion-solar-battery-48v?variant=32791453401150&country=ZA¤cy=ZAR&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gad_source=5&gad_campaignid=809886143&gclid=Cj0KCQjwnJfEBhCzARIsAIMtfKJKp3-beJViPqdv4TJaEzs0ZT_OUrmWwKEpCqEfxK05pNNkdiKkdg4aAuH9EALw_wcB

I am using a victron easy solar 5kVA, settings was done by installers, think they mentioned 52.5V (must just double check)

So I had 2 x UP5000 pylontech batteries installed in February of 2022, I started having issues now in March/April 2025 with the batteries not holding capacity during a load shedding cycle. The installer removed the batteries last week and took them to a test facility, they advised me this morning that the supplier of the batteries says they not under warranty, and that the batteries have swollen, and they are not repairable. I am seriously annoid and not impressed with the Pylontech batteries, before them, I had ReVOV batteris that gave me issues from day one, now the Pylontech swells up within 3 years.

Don't unfortunately have the cable to access the settings to change them. See the Victron cable required to access inverter is around R1k to R1.2k

Hi all, is there recommended generators that are know to work well with Victron Inverters? I have a Mac Afric generator and a Victron easysolar, but the Inverter doesn't seem to like the generator.

Must be honest, weather wasn't favourable, heavy overcasted, and they have not seen 100%, it came up to 91% at max. Our substation also burnt, so we without munic supply for 4 days already. I tried charging the batteries with my generator, but the victron easysolar does not want to accept the generator (MAC AFRIC JDP10000E) supply. Contactor pulls in and falls out almost immediately. I don't know if the settings in the inverter is set to accept the generator. Also I get a high cell voltage alarm on the inverter.

Dear all, I have been noting recently that my 2x UP 5000 batteries seem to be discharged very quickly even though the load drawn is quite low. This was noted especially when the battery has around 32% charge left, my house would be drawing around 300Watts of load, and it would drop 1% every minute, thus it discharges approximately 10% in 10 minutes with a 300W load (battery temp 24 degrees). The batteries was cycled daily and unfortunately the temperature was never maintained at max 25 degrees, which is difficult to do anyway. This doesn't sound right for the battery to discharge so quickly. Have to look at how to contact pylontech to see if they would warrant the product or if I would be left to fend on my own to get the challenge resolved.

Thank you for the feedback.

Want to ask if this inverter and battery are good quality? Do they work well together or can one expect it to give problems? Any advice appreciated.

Hi JNTM, thanks for your reply. Maybe I may have been miss informed by the original installer on the exact working and limitations of the system. I was however clear with the supplier that the aim for installing my system is to be less dependent on the grid (I would want to supply my loads critical and non critical) from the solar/battery system when obviously there is sufficient sun available. If there is a shortage of sun, or if I aim to draw big loads (typically my geyser), I would use the eskom supply, and this would involve some manual switching of my system on my side. Thus, the battery would supply load 60% every day and stop at 40% reserve to hold that for if their is unexpected load shedding, and if there was no load shedding, the system would charge the battery back to 100% in most cases, sun availability dependent. The average soc should thus be on average more than 40% since the battery is cycled daily.

Hi @JNTM, The Various users was added over time due to the various and ongoing issues experienced from day one with the batteries in question, the battery supplier was added as a user with the first battery having issues, and they were not able to address that at the time, whereby they replaced the full set. I since reduced the users to the minimum. I would love to see and better understand the mentioned screenshots as well as to understand what the cause is that leads to this battery doing what it is doing. I might be missing the point, but my understanding was that the ET112 is to prevent feeding back into the grid?? My understanding of the SOC of 40% was that assuming grid supply is available, and the battery is fully charged, load can be drawn from the battery by either the essentials and/or non essentials up to the 40% limit upon which the inveter switches over to grid supply. Assuming battery is 100% full, and grid supply would fall away (say due to system fault in the grid), the battery would only supply essentials loads (no supply to the non essentials from the battery) up to such time that grid supply comes back, and assuming this drain went past the 40% soc mark (say 15%), then power to grid is restored, the grid would charge the batteries back up to 40% soc. Also note the battery stays at 40% soc for only around 10 hours (21:00 - 07:00) where after it starts to charge again with solar. Also, whilst the battery is sitting at 40% soc, load is supplied from grid, this should not damage battery if large loads at switched on, since the battery is not feeding the load. What I also don't understand is the fact that the battery voltage jumps down to 36v and back up, and that being said, the system drained 2 days ago down to 29.5% with the inverter monitoring the ve bus. When the new bmv was installed, that evening (yesterday) the battery drained to 40% and completely shut down. Things are not making sense, or I am slow.

Definitely will thanks. I am considering a battery change as this is already the second set of the same battery type. Not shooting it down, just saying. Would be good to change to see if other brands have same type of hassles.

Not on a UI, you have to have the right software and hardware to connect to the battery to be able to see the volts per cell. I don't know what it is, all I know is this battery is rubbish and I want it gone, tired of the battery supplier and the battery. It left me in the dark again tonight, Eskom is on, battery drained to 40% and switched off, doesn't want to stay on when I try to switch it on. True, will likely be an issue to get insurance to accept that it is due to lightning, and probably impossible to proof, but hell, battery is not even 1 year old, so if it is used up, proofs my point that the battery is a load of ...... Wish I had the tools to access the battery myself. Will investigate which batteries are the better ones to use with the Victron product.

Hi guys, I am back to ask for more advice again. So today the BMV-700, shunt & the ET112 devices was replaced with new units. I ran a discharge test on the batteries to see if it would now drain less than the 32%/34% drain I got before. I managed to get to 29.5% when the battery gave a low alarm and switched to Eskom supply. Thus I can only get 70.5% use of the battery before getting a battery low alarm. This is not right, as I was previously able to get down to 0% before the whole lightning strike issue. I suspect the battery sustained damage during the lightning strike...? Is it even possible? How does one fault find it and proof if the battery is now faulty? Seriously pulling out my hair here.....😠😠😠!!!

Exactly what I am thinking.

So for interest sake, the battery supplier's response is as follows: When you run a Carlo gavassi meter (ET112) and you don't have sufficient solar on your roof, and you feed back to the inverter to the non criticals with a SoC of 45% in ess, you will stuff up the battery. To monitor the ve bus from the inverter is not the right way to measure your battery, the most accurate way is with a bms of smartshunt (Victron Energy Battery Monitor BMV-700). Ok, so i have a few questions. 1) If the (Victron Energy Battery Monitor BMV-700) was damaged by the lightning strike, you cannot use it (waiting for insurance approval to replace it), the next best option is the inverter or nothing. What does one choose....No brainer! Let the inverter monitor battery voltage whilst the Victron Energy Battery Monitor BMV-700 is out of action. 2) What do they mean by "you run a Carlo gavassi meter (ET112) and you don't have sufficient solar on your roof, and you feed back to the inverter to the non criticals with a SoC of 45% in ess, you will stuff up the battery. ". - What is sufficient solar on the roof? I have 15 x 355W panels, is that not sufficient for a 5kVA easy solar? Do they need more panels? - I don't understand why you cannot feed back through the inverter to the Non Essentials with the ESS in a 45% SoC? The battery drops out at low voltage at 32% in any case, meaning i cannot drain the battery less than 32%, yet they say the battery is working fine.... Any help would be appreciated. Thanks.

Just an update, so even after setting the Victron to monitor the battery voltage, the inverter (Victron Easy solar) kicks out a battery low alarm when the battery shows 32% on the Victron Color Control GX. I thus suspect that either the BMS of ReVOV is faulty (i.e. sends an incorrect signal so that at 32%-34% it shows battery low), or the actual battery cells got damaged by the lightning and the cells are reporting the incorrect voltage to the system.

ReVOV LiPo4

I changed the inverter to monitor batteries for now. Have the ReVOV Lithium type batteries, not sure how they do there come (i.e. CAN-bus).

Yes, ccgx seems to be on latest version v2.73. Victron battery monitor not detected during scan. Thanks, set Multiphase regulation to “Total of all phases”.

Victron battery monitor device not in list.

Hi All, I would like to ask some advice on an issue I have been having after lightning struck my solar system. The setup is a Victron 5kVA EasySolar with 10.24kW battery bank. The inverter was recently struck by lightning and got damaged ( no longer inverted power when grid is available, when grid fell away, it would still invert the power). The complete inverter only was replaced through insurance, and after replacement of the inverter, i started noticing a few issues: 1) The battery monitor (victron unit) was not picked up by the easy solar. 2) I would be getting low battery indicator on the inverter, and battery would shutdown, thus leaving us in the dark. 3) The battery on inverter would still show battery capacity available as 34%, but then I get a battery low light on inverter and system shuts down. What can be possible issues, is there other items that also got damaged due to lightning strike which was not detected? Has the battery sustained damage due to not discharging below 34%, and dropping out when reaching 34% (basically battery thinks it is at 0%???), give me only 66% useable capacity? Any help would be greatly appreciated. Thanks.

Ok, I am looking to get increased battery capacity for the evenings, current 10.24kWh is too small. But considering if I should go to another battery brand (Pylontech, Freedom won). Not sure how that would integrate with the REVOV batteries.

I fully agree.

The supplier swapped out the old set of batteries with a new set, haven't had issues since. What i have noted however is they have removed the option where excess available solar would be pushed to the Non essential loads, thus, all the Non essential loads (Geyser and stove) are now fed directly from the Eskom supply. Has caused an increase in consumption from the grid again. I suppose they do this to better protect their batteries, since they don't want these heavy loads to work from their battery.
