Hi yáll, hope you are all well. Just some feedback re this Riio Sun inverter shut down. After doing a software (firmware) update the problem has been solved. Agents did it remotely and now the system works without shutting down at the start of loadshedding. Regards

@jumper agreed, but I need more than 60Kwh storage capacity and the max 15 batteries in parallel that Kodak allows, will not be reached if I use the BL3.6's. They have explained that I can add another 2 BL3.6's over and above the 15, but to not connect their link cables and use them without the comms cables. This I suppose is an option if I am only aiming for 60Kwh, but I am aiming at a MIN of 60Kwh, probably closer to 70Kwh storage is needed. So now I still don't know what to do, other than to try and sell my 4 x 1yr old BL3.6's and then to build my battery bank from scratch, with the BL5's or any other acceptable battery brand. I don't know if there would be any interest in the 4 Kodak BL3.6 batteries? Regards

So I have 4 x BL 3.6 batteries installed in parallel, with 3 Axpert King inverters. System works perfectly, but I want to increase storage progressively until I have more than 60Kwh storage. So I noticed while getting pricing on 6 new BL3.6's that the BL5 is available and cross compatible with the BL3.6 batteries. So I obviously became very excited at the prospect of being able to rather add BL5's to my existing bank, as I will be able to get closer to my storage goals, as I can only connect a max of 15 Kodak batteries in parallel. So when I inquired about the BL5's compatibility, the agents said that I must make the BL3.6 the master battery and the BL5's slaves. They also told me that thje BL5's would loose their 4.94Kwh capacity and only supply the same capacity as the BL3.6 batteries, which is 3.686Kwh. So in effect you loose almost 30% of storage. Does this make any sense to anyone? Then I also asked if Kodak can work with a master controller and manage more than 15 batteries, like the Pylontech batteries? I can't seem to get a straight answer yet. Does anyone here maybe have these answers? Thanks

Hi guys, just some feedback re this issue. I have spoken to another installer who had exactly the same problem and after installing a second UP2500 battery, the issue was resolved. He also said that a firmware update was also done. We will be doing the firmware first and then report back.

Thank you BRC, I will try your advice and see if it makes a difference. I have a few relay boards here that I was using for my Raspberry Pi4 to create an autostart for my generator, but have dropped that for now, as I will be installing a micro Hydro pelton soon, to cover my own baseloads 14/7. So at least I have the relays. Thanks

Hi all, hope you all had a great weekend. So just to give feedback re the SPD installation and whether it worked, well unfortunately it made no difference and the inverter still shuts down when loadshedding starts.

I am not to sure. The client informed me that he only has power from the inverter for about 2-5min after loadshedding starts. I went to test his batteries, did various diagnostics incl loadtests on his batteries and found one gel battery to be faulty. Then we quoted on a lithium battery, which he approved and we installed. I tested it manually and then the next day the client phoned and explained the problem.

Hi, so the only thing I changed was the battery and the corresponding required settings on the inverter, then we noticed the problem when loadshedding starts. When I replaced the gel batteries with lithium, I tested the setup, by manually switching off the Eskom supply to the inverter, to see if the battery and inverter were working correctly, which they were. The next day I received a phone-call informing me that the system shut down when loadshedding started. Then I started checking for possible causes, to no avail.

News just in: Murphy has moved on and we are scheduled to have loadshedding this evening from 20H00-22h30. So we should be able to see if the SPD has resolved the problem. Keep your fingers crossed. I will update once we know.

Hi BRC, thank you for your interest. The installation is outside a small village called Wolseley, near Ceres (where the fruit juice comes from😉) in the Western Cape, South Africa.

Thanks Bob, the system is currently installed in a rural area on a farm that is supplied by a 11KV line stepped down to 380V 3 Fase and according to our knowledge there are no Grid Tied installations on this same feed, but we could be wrong. This inverter is single fase and is only supplied by one fase.

Hi all Thank you firstly for all the ideas and advice, much appreciated. @coulomb I also thought the mode setting might make a difference, but unlike the familiar Axpert inverters, the Riio Sun differes in its mode settings and explanation of the mode functions. Setting are as follows: 0-AC First 1-BATT First 2-Time Ctrl 3-Ubat Ctrl/ SOC Ctrl 4-AC IN backup Default:0 (AC in source priority Note: ACin First: The system will work in AC input first mode (default) When there is an AC input, the load will firstly be powered by the AC input. When the solar panel is sufficient to charge the battery independently and there are still some surplus solar power, it will also supply power to the AC load together with the AC input. BATT First: The system will work in battery first mode. When the PV power is more than the power of the AC load in operation, the solar energy will charge the battery and supply power to the AC load first. When the PV power is less than the power of the AC load in operation and the solar panel is insufficient to take the AC load, the battery will discharge to supply power to the AC load together with the solar panel When the battery is running low (lead-acid battery under low-voltage protection or lithium battery under SoC protection) and both solar and battery are insufficient to power the load, the AC load will be powered by the grid only, and the battery will be charged by the grid as well as the solar panel until the battery is charged at constant voltage and the overload is removed, the system will disconnect the grid power supply and restore to the battery first mode. Time Ctrl: Set the time period for the BATT First mode, once it exceeds this time period, it will automatically switch to the AC input to supply power In the ACin Logic Time Ctrl setting in the TBBLink User Control interface, up to three valid periods can be set In the ACin Logic Time Ctrl setting in the TBBLink User Control interface, you can turn ON/OFF Auto Charge when U_BAT_LV Warning to choose whether to automatically switch to AC input charging when the battery voltage is low Ubat/SOC Ctrl: Battery Status Mode When the battery type is non-TBB SUPER-L, the Ubat Ctrl will be displayed, and the ACin First power supply can be turned on/off according to the battery voltage. 0-AC First 1-BATT First 2-Time Ctrl 3-Ubat Ctrl/ SOC Ctrl 4-AC IN backup Default:0 At present it is set to 0-AC First. I don't know which of the other settings will possibly correct this and the system needs to be automatic for various security reasons. I have installed an SPD on the AC supply side of the inverter, but since then Murphy has postponed loadshedding 🙄🤯 so I have not been able to test if this has fixed the problem.

My confusion stems from the fact that when I disrupt the Eskom supply to the inverter, by manually switching off the isolator on the supply, the inverter switches over to battery mode immediately and carries the load without a problem. When Eskom disrupts the supply to the house ( and inverter) when loadshedding commences, the inverter shuts down immediately. Then I manually start the inverter and it continues to carry the loads, until either loadshedding ends or the battery is depleated. This is the most confusing that blows any theory I have, out of the water.

That is what I am struggling to understand. I am clutching at straws, but I figured that there must be some feedback on the neutral or something. Oh, I forgot to mention that this house is fed by Eskom 3 fase power. One fase feeds the inverter. Could it be than when Eskom disrupts their supply, that there is some residual power on neutral that causes the inverter to read a critical malfunction and shut down? Would the surge protector I installed solve this? The inverter does not display any faults or error codes. It shuts down completely, but you can manually re-start the inverter immediately after that and it works perfectly until the next loadshedding.

It is only supporting led lighting and three plugs ( bedside light, cellphone chargers etc, no fridges no microwaves.

Thanks Coulomb, I am struggling to find a workshop/repair manual for this inverter. The inverter however is only just on a year old now.

Hi Yáll I have been having a problem with an existing installation, where I replace 2 x gel batteries with a Lithium battery. The installation was a Riio Sun 3 Kw 24v inverter that was connected to 2 x 12V 105Ah Gel batteries. The system was used as a back-up for loadshedding, no PV panels connected. The inverter only runs a essential loads, with a base load of ≤500W. Everything on the original installation worked well for about a year, then the inverter was only able to supply current for about 5-10 mins. I tested the batteries, to find one battery to be faulty. I then installed a Pylontech UP2500 battery, as the UP2500 is fully compatible with the Riio Sun, using CAN for BMS comms with inverter. Did the installation and tested the system manually and everything worked according to plan, after changing the settings on the inverter as per the manual. The can cable pin-outs I also used according to confirmed diagrams. The inverter supplied power to essential loads in excess of 6hrs. Then a problem started rearing it's ugly head. Everytime loadshedding commences, the inverter immediately shuts down and needs to be manually re=started by pressing the on button. Once booted up, it operates normally and supplies current to the essential loads for the duration of loadshedding and when Eskom supply returns it switches back over to Eskom as primary supply. If I switch off the Eskom supply to the inverter manually, it works normally and supplies power from the battery. The second Eskom loadshedding starts, it shuts down totally. I have attached the Riio Sun's manual just in case I have gone through the settings many times, but can't seem to find the problem. I have even installed a Surge protector on the supply to the inverter, just to be sure, but earlier today the Eskom supply dipped and the inverter shut down and needed to be started manually again. Cab anyone offer some help with this problem please, as I am pulling out what little hair I have left. Thank you RiiO Sun User Manual.pdf

Hey RiPMonster No problem. So if the fan does not work when the temp is that high, does the inverter publish an error code on the screen? On the King it would be either a F01 which is "fan locked" or F02 "Over Temp". If the inverter/s don't publish an error code, then it might be because they haven't registered an over temp, or there might be a bigger problem. Have you possibly checked if your fans are free, as in freely rotating. When last have you done a firmware update on your inverter/s? What inverters do you have? My inverters are connected to a Pi4 with ICC software and the software actually displays the inverter temp and the main dashboard, as shown on the screenshot at the top center of the dashboard. It might make sense, depending on the make and model of you inverter, to purchase and install a Pi4 with ICC software. The people at ICC, in my experience, are very helpful and approachable and I have no complaints about the software, it works like a charm and I can log-in remotely and change parameters as well. ICC have kits for sale, depending on your set-up, make of battery etc. Best contact them, before ordering. Regarding the lighting of a cigarette, Hmmm that is a difficult one, unless you light your cigarettes with a flamethrower 🤣🤣🤣😇 I can't think of one reason why that would happen. I hope you are able to find the problem/s, if any. I am truly inquisitive to know what the connection between lighting a cigarette and the inverter fan is? Good luck and please let us know what transpires, or if you need anymore info. Regards
