Welcome Neville, The Inverter you can get here on the Power Forum store https://powerforum-store.co.za/collections/inverters/products/solis-s6-pro-6kw-advanced-hybrid-inverter the battery you can get at Electromann sa https://electromannsa.co.za/shop-the-latest-affordable-gadgets-online/svolt-51-2v-5-43kwh-106ah-wall-mount-s-type-lithium-battery-reliable-and-efficient-power-source/

Found the reasoning behind this it uses a Pace bms with a charging balancer. The restrictions are built into the bms in order to give the cell balancer time to do its work. When the imbalance between the cells are higher the limit charge current will be lower. Hope this helps someone. Used the following to access the cell voltages etc. Pace PBMSTools https://cdn.shopify.com/s/files/1/1249/8241/files/PbmsTools_V2.5EN.zip?v=1600336921 Cable https://solar-assistant.io/shop/products/pace_rs232 Drivers https://cdn.shopify.com/s/files/1/1249/8241/files/CDM21228_Setup.zip?v=1621934743

Two things: 1) Try to shift as much electrical work as you can into the daytime hours. At my home, for EG, the pool pump runs only during the day, dishwasher only runs in the morning, water heating is early morning and then midday. Generally we try to use very little after 5pm. These are our own rules, sometimes enforced by timers (EG pool pump). We do this to reduce the load on the battery after hours, thus extending the protection it can give us. Remember that your system is weakest in the morning, and a combination of early morning outage and overcast weather will be its toughest test. I usually have about 55% of the battery available after the early morning water heating (heat pump, so faster and lower consumption than an element). 2) Following on from (1), decide for yourself a minimum level of battery you MUST have at all times whilst there is grid power. In my case this is set at 40%. I will always have 40% at least in the battery when the grid goes down. If SOC reaches 40% and the grid is up, the system will pull from the grid instead and leave that 40% there. So in the worst case scenario I describe above, I will always have a useable 30% in the battery to power the essential circuits until the sun comes out or the grid comes back on. Saving money on your bills is important. Solar isn't cheap, and you need to see some return on your investment. But we need security too.

Just upgraded to Solar-Assistant 64bit - some nice features https://solar-assistant.io/help/updates/changelog 2024-04-05Beta New features: Released 64-bit Raspberry PI SD card image. Add HDMI output configuration option to switch between kiosk and console. Add SSH configuration option to enable/disable SSH key and password based authentication. Add Bluetooth configuration option switch between disabled, hidden and auto pairing. Add power management for Luxpower inverters. Add power management for Growatt TL-XH inverters. Support for GoodWe ET inverters. Support for Seplos V3 via "USB modbus" protocol. Added reading of serial, firmware version and alarms via "USB Narada" protocol. What I noticed: SA Image is based on Debian 12 64bit - previous was based on Debian 10 32bit Ability to allow ssh into the RPI - previously I had to hack the image to allow ssh Improved security by removal of ssh on frp proxy. Kiosk mode - displays SA on HDMI Might be useful to have a local display showing live SA. I'm thinking of adding a HDMI display to my RPI4 eg https://www.raspberrypi.com/documentation/accessories/display.html so I can see SA when in the garage. ssh access is configured via Configure -> Configure Local Access. The process I followed to go from 32bit to 64bit: Download the 64bit image and write the image to a new/spare SD card - I used a spare 32GB card Using a different SD card allows you to revert if the new image does not work as expected. Make a note/print-screen of SA settings eg USB ports are used for Inverter & Battery, etc. mqtt settings: Configuration -> mqtt -> Advanced button inverter & battery settings: Configuration -> battery -> Advanced button Make a backup via Configuration -> Storage -> view detail -> backup This will create a backup that you can save to your PC. There is a button to download the influxdb backup.zip Shutdown & poweroff the old 32bit version - Configure -> System -> Shutdown Install the new SD card with 64bit version and boot the RPI Check your DHCP server/nmap to locate the 64bit SA on your network Access the 64bit version with a browser http://192.168.7.189 in my case Check the site Owner/Site ID under Configure -> System Since you are using the same RPI hardware/machine-id, SA will connect to existing site license. Might take a minute to retrieve the license from the SA cloud. Restore your influxdb backup via Configuration -> Storage -> view detail -> upload Remember to import the backup as well. There is a button to import the backup. Check your history - mine was fine, but there is a resample history link. Configure USB ports and other settings as per print-screen (2) above Check for any updates - I'm on the beta program and on Software version: 2024-04-05 Enjoy.

I had the following SOC settings on my Sunsynk 5k inverter and battery solar system. 16h00-20h00 100% and 20h00-16h00 35%, which worked well for whole summer so far in Somerset West. Following some grid supply issues due to winddamage, I recently kept 16h00 20h00 at 100% but changed 20h00- 16h00 to 50% to have more back up. However, battery now only discharged to 70%, even if I change back to 35%...? Battery shutdown at 20%, restart 30% and low 20%. What did I do wrong?

Nicely done @Steve87 What car is it charging? Don't suppose it or the car support feeding the house with power from the car's battery...

Hi Guys... So, my BMS issues in the end were not sorted out. It just prolonged the effects of the drift to over a week before it became apparent that something was still wrong. Solis is JHB do have 2 BSL Batteries that they managed to get their hands on and are currently testing. But they are also experiencing the same issues. The local BSL distributor is also in contact with the OEM in China to figure out what's going on. Another issue I picked up is when the battery dies and grid is restored, the back up port doesn't work. It only worked the next morning when pv was available. This is something that even the Solis guys in JHB are baffled at and are looking into it...

Article in PV magazine regarding progress on Soduim batteries. https://www.pv-magazine.com/2024/01/11/acculon-launches-production-of-sodium-ion-battery-modules-packs/

Inverter settings as follows: Bulk charge voltage 56.4v Float charge voltage 54.0v When charging the battery shows 54v, 100%. However, as soon as the power to the inverter is switched off, the battery drops to about 50v. Is this normal? (Inverter load around 300watt)

Hi All , I wandered if you could possibly help me with a protocol issue? I have a Sunwise 48V batt with a Pace 15s BMS. I have a MppSolar 5048MGX inverter. I have connected the pc to BMS via serial adapter to rs232. In the PBMSTools for changing protocol, the Inverter Protocol in the BMS shows "Paceic" , but none of the software's will allow me to change it. They all pop up with "Write Error" . I have also tried the other PBMSTools which allows you to see and adjust parameters and tried to change the protocol in "System Config" , but the same problem, same error. The Battery Manufacturer were supposed to install MPPSolar protocol which I supplied them with from MPPSolar, however they claim that the default protocol is PYLONTECH. I have tried making a number of cables using the pinout supplied by both parties but only get Fault 61 " non Communication " Have you any idea on how to change the inverter protocol in the BMS so the inverter can talk to the battery via RS485? or I read a discussion about possibly using CAN and changing the settings in the inverter to user defined ? I would appreciate any help on this as the manufacturer is not helping so much. Cheers

Hi Everyone so I got a luxpower SNA5000 and Svolt battery for about 6months now, everything works well. Today we had a planned power outage from 8-16:00. at 13:10 my battery was at 72% and then it just shut off my electricity. The inverter and battery was still powered but nothing on the DB box. when electricity came back on the battery came back. Any advise what could be the problem. I'm a dummy with these stuff.

Hello I need some help, I have a debate with a technical manager at a solar company regarding the charging of a Lithium Ion battery,the supplier device does not have the option for a Lithium battery, it is a 3kVA inverter. The charging algorithm is shown below. The supplier insists that just by setting the floating charge and bulk charge according to the battery(Pylontech UP2500) that it will not cause any issues. The inverter also shows SOC of the battery on 70-80% whereas the battery SOC indicator states 40-50%. The supplier stated this makes no difference. Please assist. Regards Yashin

Hi All Has anyone been able to get a Leas Acid battery working with this inverter or any non-genuine lithium battery. I just upgraded the firmware in the inverter and no better. Just upgraded Solar Assistant to Beta version to see if that helps. Thanks Wildgrav

Any insight on the purpose of that option ? Supposed to be used when installing a new lifepo4 battery ... But for how long ? 1, 10 or 100 cycles ? What does it do precisely ? Haven't noticed any difference in current limitation for charging & discharging when option is ticked or not ...

Hi all, first post hoping someone can point me in the right direction. I have the following setup that I installed myself around 5 years ago. We are off grid and have a WKS Evo 5Kva inverter (same as Axpert King I believe) with 4 Pylontech US2000 Plus batteries, these are supplied by 9, 300 watt solar panels. Have had a few issues with random shut downs even when batteries are well charged, not sure of the reason for this, but recently kept getting alarms and one battery was consistently at a lower charge than the other 3. It was number 3 in the chain of batteries. I removed it from the system which seemed to solve the alarm problem. On inspection, the battery is swelling, so in the process of either returning to our original supplier or dealing direct with Pylontech. I bought a replacement Pylontech US2000C and tried to connect it as the master battery, but it would only run for around 15 minutes before switching off. Having read through a lot of posts on here, I am thinking I need a firmware upgrade for the control panel so that the inverter will communicate with the new battery. Side issue of needing to charge the new battery as I left it turned on but not connected after trying to install it, not entirely sure of the best way to recharge it. Can anyone direct me to what firmware I might need and how to install it. I use Watchpower to monitor the system and if I am understanding correctly the current firmware versions are Main CPU 00071.61 and Bluetooth CPU 00000.21. I've added a photo of the identification label which clearly has King in the name. Would be good if someone could help to identify which version this is. Regards, Barry, Extremadura, Spain

LTO cells are actual batteries and are usually 10C or more rated, rather expensive relative to LFP cells, but they are not Capacitors, Super, Ultra or other. Partial extract...Lithium Titanate (Li2TiO3) — LTO  Batteries with lithium titanate anodes have been known since the 1980s. Li-titanate replaces the graphite in the anode of a typical lithium-ion battery and the material forms into a spinel structure. The cathode can be lithium manganese oxide or NMC. Li-titanate has a nominal cell voltage of 2.40V, can be fast charged and delivers a high discharge current of 10C, or 10 times the rated capacity. The cycle count is said to be higher than that of a regular Li-ion. Li-titanate is safe, has excellent low-temperature discharge characteristics and obtains a capacity of 80 percent at –30°C (–22°F). Additionally addressing the title, yes, if you say you have a super capacitor battery, which actually contains LTO cells, then you are lying, if you have a bank of supercapacitors, then that is what you have, not a battery, but a bank of capacitors, super or other. The problem with capacitors is that the discharge curve is not very useful in replacing a battery, you could with lots of extra boost regulation, for each capacitor in series, attempt to end up with something resembling a battery with a discharge curve that becomes more useful, but I suspect that the extra cost involved with all the extra control and boost circuits may make this lot less than financially viable.

Hi, I have a pylontech US3000 battery and it always only charges to 76% and then stops charging. I've already tried everything and nothing helped. When I plug in another US3000 battery it charges to 100%. Can you advise me how to charge the battery? I have a PV array SUN-6K-SG04LP3-EU Pylontech US3000 Thanks

Hi everyone My name is Neville Just about to move from 12v inverter and batteries in camping trailer to a home install . I want to purchase a Solis S6 6kW Pro Inverter and a SVOLT 51.2V 106AH 5.43 KWH battery any reputable suppliers , please share details thank you

Hi I'm posting photos of specs of Inverter as well as battery, there is no name on the battery ! , I'm hoping someone will recognize the make .

My Pv not Charging Battery but Utility is charging battery What might be the cause

Item Wanted: Used Dyness F10 battery working condition Packaging Essential: no Desired Age: 2-3 years Location: anywhere Willing to accept a shipped item: yes Ballpark/Budget Amount: R20K Contact: [email protected]

Hi all, New to this. I just recently purchased a new Svolt 5.09Kwh 48v 106ah Wall Mounted Battery and was going to purchase the Luxpower LXP Hybrid 5K Inverter. I sent them an email to see if it’s possible to get it compatible with a cable modification or something else and was given a few words about what’s possible. You can leave it as lead acid mode and limit charge voltage and floating voltage according to battery manual. Which doesn’t sound like a good option for me, so my main question here is what other hybrid inverter (reasonably priced) that I can look at that will be compatible. I’m preferably looking for IP65 (higher humidity is the main reason), I’m less than one kilometer from the coast, but it’ll be in the garage out of weathering conditions. Wifi/GPRS Internet access. Something similar to what I already was looking for, hybrid-backup for the load-shedding . I would appreciate all the help, thanks. Regards

The small 3kW I guess is working off a different battery. Further because his battery is already low less than an hour after sunset being at 50V one must find the reason. Is it high load of battery not fully charged or?. Just my input based on the very limited information of the PV system. They say little information is always a dangerous thing.

You can but first check charge voltage and float voltage are the same or very close as not to overcharge or under charge any. You'll have to choose "USE" on battery type and set voltages according to battery specs. Preferably just 0.3v lower Currently I've paralleled AGM with Lithium. No issues at all. You won't have communication with the inverter

Finally, I have had the chance to explore the Solis S6. I have some very interesting information to share. Takes some getting used to having no display or touchscreen...Was it needed absolutely not. It took some time to get used to it but, when using your mobile phone as a local direct Bluetooth connection it just makes a lot of sense that there is no money wasted on a display. It took quite a while to figure out how to pair the device to the Solis cloud application but we got there in the end through some perseverance. The SVolt battery also just paired very easily with a straight 1:1 cable CANbus & Pylontech. I noticed a cable tray that almost is identical to the Sunsynk/ Deye 8kW inverters. However, the inverter seemed to have a higher quality of components. What was especially interesting was a sim card embedded as well as an antenna. I haven't fully exploded all the options on this Solis but it does seem like there is some GSM type of connectivity option for that Sim card to be present. The large Battery LED as well as other warning & information LEDs make for a good idea as to what is taking place on the inverter. I look forward to many more of these S6 units and I'm so glad there is another option on the market other than Sunsynk & Deye. Best of all no 6 weeks wait time of there is a problem with the inverter. This was a first look see install & from what I saw I really see quality & simplicity.
