I hear you @Steve87 sadly what it then means is that I would have to use PMBStools, reading each battery using a RS232 cable connected to each battery pack in order to periodically monitor if any cells are totally unbalanced or if something is out of wack. Alternatively once the battery throws errors is when one can engage FW to see what the issue is. Preventative visibility is better I think hence my wanting to see some of the granular information. But, as you say, sadly this is unlikely to be implemented nor to be considered. When doing this again, this would not just benefit my particular plant but it would've been generic across all FW eTower batteries communicating with Solis.

Succinctly put @Steve87 now the next battle is getting to have information displayed on Solis Inverter in respect of: Correct number of Cycles Number of parallel connections Battery Packs (number of single module core strings); and Number of Battery Modules in Series Already FW has indicated that this is a Solis issue via email which I have shared with Solis and hoping to get a way forward and resolution. My knowledge (limited as it is) indicates that this would be a BMU/BMS issue which the two of them ideally should work together to do a firmware which would give a resolution, unless the eTower PACE BMS is not physically able to do this, but I guess I have to wait and see.

@Steve87 I'm in the same boat with you in terms of having to remove the battery and cart it off back to manufacturer, moreso as I'm not in South Africa. The cross-border logistics and time become not only tedious but also very expensive both in time and transportation. FW does have a local distributor but because I bought the battery directly from FW through the PowerForumStore they were not wiling to assist (rightfully or wrongly so), that's another story. Fortunately, to be fair to FW when they had a tech coming to their distributor he took the time and sorted my issue within half a day, which I was very grateful for and also on warranty. So I've not entirely lost faith in FW and do recommend their timeous attendance, on the whole, of their tech support team and professionalism.

@Steve87 for the sake of the local markets on the African continent and in particular South Africa, I certainly hope and pray FW and all others in various sectors pull up their socks. Just off the top of my head it made me think of the demise of Nokia and Blackberry vs how Apple came and decimated the market landscape in the mobile sector. We unfortunately then become beholden to external suppliers and this effectively means no jobs for our local people and markets save for scraps.

Looking forward to the continuation of this story with bated breath... especially as I also go through my own issue with FW but more specifically in relation to an eTower BMU.

Out of interest definitely would be keen to explore and try your products. Just a couple of questions though: Would you ever consider or are you in the Southern African region (Zimbabwe, Zambia, Mozambique, Botswana)? How well do your products perform in areas where Internet network connectivity is erratic and not the best, in terms of data collection and aggregation?

Many thanks for the response, I have since sent an email to Solis at 18:27hrs (16 July 2026), ticket ID# 984064

@Yellow Measure As I've indicated Solis team service representatives gave me a commitment, last comms was in January 2026, they have been silent since then. I have not received feedback from Solis since then. Trying to engage them on a public forum is in the hope that I get traction and a response. If at the end of all this, the whole issue lies squarely with FreedomWon not playing ball, would it be unfair for me to have expected a response from them indicating what has transpired, initially privately? Secondly, I have not said Solis nor FreedomWon products are bad, AT ALL, in fact am very happy with the products I have from both, it's the issue of a dropped ball in relation to only a specific issue, which I am now getting clarity on this forum that this is a FreedomWon BMS not sending the information to the Solis app/web portal. I have no reservations, at all in apologizing to Solis. If you had engaged them and their representative commits to getting the issue resolved in partnership with the other party and then it's not done, what is the recourse? In my humble opinion, the recourse is to say, "listen we have engaged the other party and they are not playing ball or you have old hardware that is not able to get what you would require" or whatever the final story is and then the matter rests. AGAIN and for the record, would I purchase products from both vendors? ABSOLUTELY and without reservation and am intending to do so again.

I also spoke to Solis guys who promised to work with FreedomWon to get a resolution, so both parties’ support staff gave commitments and promises. My problem I guess on my part was that the comms were via WhatsApp calls but I have names from both parties who made these commitments.

Would be keen on also getting to find out regarding this issue. For me my loads are generally sorted in respect of the battery but my 200w panels are beginning to reach end of life and I used to have 12, now I have lost 1-panel and the others look like they will likely fail soon, so before I can afford new panels would be keen to see how I can get a generator to work as a charger for the batteries and carrying the loads through the Solis.

@Yellow Measure too true, but what would anyone do who is an ordinary customer when faced with a manufacturer or manufacturers who are the makers of the product?🤔

@HennieL I personally did research for my inverter and battery over the course of almost 3-years solid and was really partial and drawn towards the Sunsynk until the reports of inverter issues taking over 6-weeks or longer began to resurface. Granted the huge levels of sales and lack of commensurate growth of their after-sales and support side, may clearly have been the problem, but if one is going to take over 6-weeks plus without a backup option, moreso in the times when loadshedding was at its peak becomes problematic for me and am sure for anyone. On the battery side, I've had an issue with my first purchase via the @Powerforum Store which was no fault of theirs and they were absolutely supportive in linking me up to FreedomWon, who in turn were equally supportive. My only gripe was that their local distributor would not assist me, at all, since I had made a direct purchase. Eventually the battery was fixed, on warranty but being outside of South Africa posed a huge challenge. I also further purchased a second FreedomWon battery and up to date, no issues for both Solis and FreedomWon save for the BMS information issue. Would I recommend both brands, absolutely, but clearly they can do better in respect of missing or incorrect information.

Yes @Yellow Measure I logged the issue and they said they would get in touch with Solis R&D to work on this. This issue is still outstanding. Last comms I did on the matter was in January 2026 with team at Solis Zimbabwe support and it's always a back and forth blame game till eventually I got frustrated and tired.

@Powerforum Store you are very correct in the information you have shared and I engaged FreedomWon customer care and technicians in this regard and they advised that the whole process of updating the BMS information and it's display would require collaboration between FreedomWon and @Solis Inverters SA . I continually engaged FreedomWon over many months and they in turn blamed Solis team for not their unavailability, now whether that is true or not, I have never been able to verify it hence raising it here that this issue has been outstanding since last year October (2025) when I first raised it including official tickets with FreedomWon, which they kept insisting on closing and eventually went quiet. Previously I was not even able to get the basic information such as: Total Battery capacity (Ah) for more than one module - this was fixed Total Battery capacity (kWh) - I requested if this could be received on the Solis inverter automatically - this is still done manually So the question is whether @Solis Inverters SA got any joy from FreedomWon or not and clearly since this outstanding, it means someone somewhere dropped the ball or thought my request was not important. What FreedomWon sent me was a RS232 cable so I can get information directly off each battery module and information for diagnostic purposes and I even recommended that since that cable is difficult to buy maybe it be sold together with their battery modules. Their distributor was not willing to assist me, in the first instance, as I had bought the battery directly from the @Powerforum Store. My battery had a loom issue and fortunately FreedomWon had a technician travelling to train the distribution personnel and in Zimbabwe and during that time he was able to then resolve my battery issue under warranty, so am very grateful to them for that. I not had any issues with the FreedomWon batteries reliability, to be fair, but I always want to be aware of issues before they escalate or deteriorate, hence having granular information is important, at least to me. Battery sellers and installers (some but not all) are normally interested only in the initial sale and after service is asking for the moon, clearly. So that's my backstory to raising the issue here.

Many thanks for the tag @HennieL. Number of cycles keeps going up and down as well. Today it's 10,000 on another day it had come down so clearly there's an issue with accurate comms and or capture of data either by inverter or being sent by the battery FreedomWon eTowers. I've also attached screen shot with circles in RED of area that have no info. I've also closed off personal info so that any update is done, not just for me but for ALL comms between FreedomWon eTower batteries and Solis S6 pro hybrid inverters and I know, not everyone is interested in granular information as much as I am, but it's important to have it.

I logged a request last year in October for Solis to enable ability to view FreedomWon eTower: Accurate multiple Battery cycles - on App and Web portal - still nothing has been done Battery packs (number of single module core strings - on App and Web portal - still nothing has been done Number of Battery Modules in Series - on App and Web portal - still nothing has been done Kindly assist and attend to this as this needs you to work with FreedomWon R&D team, thank you.

@HennieL funny you mention fault, we actually had a nationwide grid failure in Zim last night from 18:21hrs to 23:17hrs, though power restoration began happening in some areas after the 2hr mark. Am just thinking of relatively cheap 800w to 1,500w space heaters and their impact moreso for me with only 2 x 5kw batteries. Daytime generation definitely is an important consideration and having enough panels important but night time is greater part of any home heating, well save for areas like Capetown where you may get snow and others near Lesotho which can almost be 0º degrees during the daytime at extreme times... That 800w to 1,500w also pulls a lot over 3-5hrs of evening time, especially where a home or room does not have adequate insulation as well hey.

Am fully aware that one of the best ways to heat up a home in winter is to have a heat pump, however if one has installs a solar system with batteries, what would be the most effective way to heat up a home in winter at the most cost effective way? Ideally the method would involve or ensure that the battery systems are not too taxed or strained. Your thoughts forumites would be most appreciated, thanks.

@Scorp007 many thanks for the update and good news. Looking forward to him having a full and total recovery and his return to the forum. Tell him to stop this thing of stressing us with worrying about him (hehehehe)😂 😂 😂

Greetings forumites and @Scorp007 , hope I find you and yours well. Has there been any update or news regarding @TaliaB ?

Very best wishes, hope and prayers to @TaliaB

What happens or what is the plan for redudancy if the whole battery packs up or come cells develop issues? Would your supplier be able to give you a temporary battery replacement whilst the other is being repaired or replaced under warranty? Smaller is cheaper to add additional storage and if one battery packs up, one can limp on one or two in the pack. Space considerations would also be a consideration @MuneebK how tight are you for space?

Understandable that API, App and Web portal updates would naturally take time moreso between different vendors, however over 8-months of asking for simple visibility is poor of: Correct battery capacity (200ah/300ah) Number of cycles for each battery pack or even averaging out the cycles (add pack-1 plus pack-2 and divide by 2) to give rough average would help Information on number of parallel or series battery connections is also missing Also missing is ability for system, once connected to automatically pick up total battery capacity (10kw/15kw) etc. In short, this granular information may not be important to the average end-user but some of us do find it useful (see screenshot attached here)

@Pho3niX90 a different brand may have a firmware solution to mitigate this grid issue. @AlexTZA on the whole, the inverter has worked well for me, however, my issue with Solis is with the BMS not having been set properly with Freedom Won eTower batteries. Specifically: The number of batteries is not shown on the App or Webportal The batteries Cycle count for each battery is incorrect (I’ve confirm the discrepancy/variance by connecting to batteries directly using RS232 cable) Even if one wants to assume it’s taking average of Cycle count of all batteries, this is way off The battery pack size 100ah/200ah/300ah was only recently resolved in terms of reporting via a firmware update that took over 6-months to get I must give credit and a “thumbs-up” to Freedom Won support for continued pursuit of Solis team but it’s been like pulling teeth to get Solis R&D to get stuff done. There’s also consistent intermittent connectivity issues as well, but for me that’s more a nit pick as inverter performs very well for me and my plant. Am now headed into winter so it’ll be interesting to see how the system performs and holds up. Initially I only had 1 x 100ah eTower battery, now I have 2, so will see how efficiently it performs. Am also rather limited with a small panel bank of only 12 x 200w (2400w) generation, which had hoped to upgrade by now with additional 595w x 5 (2,975w) onto 2nd MPPT but hopefully may find reasonable priced panels given price rises caused/blamed on Iran war and fuel hikes. That info that I would love to see seems to be available easily on Victron Plants. Also the size of Battery capacity has to be input manually as well. Would be great if BMS picked it up automatically. Would I recommend Solis as my first choice? Likely yes for someone with an installer very well versed in the product ONLY. Otherwise, no. Installers who have general knowledge & experience, no. The placement of CT (either within the inverter or at whole house main grid input) and ability to send excess power to non-essential loads seems to elude some installers and how to the find a way to use Gen Port for this and also configure it for a generator appears not to be easy. As a set and forget inverter it still needs some tweaking (Solis S6 6kw Hybrid Pro Single-phase).
