Hi There, Your best bet is to have your Mecer Inverter checked by the agents Mustek, there is one in in Midrand 322 15th Rd, Randjespark, Midrand, 1685 +27 11 237 1000

Hi Kenneth, You do not specify what model your Inverter is however. Error Code 90 has been discussed on this forum please click on the below link:

@Jaco Brits Please follow Scorp007 suggestion afterwards check your Program settings: Program 05: Make sure you are in "USE" setting this will allow you to set you battery charge settings and not drain the batteries to zero volts. Program 11: Maximum utility charging current set to 20A ( need more battery info) Program 16: Charge source priority (you did not mention if you are using Solar panels) choose CUt this will charge the batteries Utility only. Program 26: Bulk Charging voltage set to 55.2v (not sure what battery type you have the default is 56.4v) Program 27: Floating Charge set to 54v Program 29 Low DC cut-off voltage (Important) default is 42v set the voltage to 47v or 46v Program 33: Battery equalization enable choose EEn Program 34: Battery equalization voltage set to 54.5v It is important to give more information regarding what batteries you have, be it lead acid or gel this helps better for recommended charge settings

@andrecar Firstly be sure the Inverter is set to "USER" as you will be able to set the inverter values as you wish. Secondly it would be easier to use the Windows app called WatchPower free download https://watchpower.software.informer.com/ as you will visually see all the value settings clearly (connection cables should be in the box your Inverter came in) use your laptop or Desktop. Lastly after you have changed the value to "USER" go to "OUTPUT SOURCE PRIORITY" and choose "SBU" Solar Battery Utility" (Utility being Eskom) this informs the Inverter should there be no sun it will revert to Utility if no Utility it will go to Battery. Solar will be first priority then Utility. In the Inverter manual you will see which number to go to if you are forced to use the Inverter's screen. Hope this helps you

Hi, Just received latest FWU from Sunsynk for my 8Kw Inverter MCU:6024-0717 at 14:00pm today. I applied on-line this morning using the Sunsynk https://sunsynk.freshdesk.com/support/tickets/7400 Nancy confirmed my update. About 2hrs later the power went off and I thought the Earth leakage had tripped, no it hadn't. Went over to the Inverter and looked on the Screen and there on the top left corner (where it normally says "ON" in a green circle) I could see numbers counting, this told me a Firmware Update was in progress. It took the best part of 7mins to load and the power came back on without an issue. I've had my Inverter since October 2021 this is my 5th FWU, never once was I given a warning on the on-line application or through my email confirmation that I should lower my "LOADS" or any warning precaution. The only thing is, you do not know when the Firmware upgrade will take place and you actually forget about it until the power goes off, then you jump to conclusions of what the hell has tripped the power off. So to conclude I have been lucky with the Firmware Updates thus far and to add, if I may, Sunsynk replaced my WIFI Motherboard and Data Logger, the Logger just stopped functioning without reason, so without any fuss, just last week, with the assistance from Dino and Chantelle at Sunsynk Joburg, they immediately exchanged my Data Logger with a new one via Courier but still did not function, the next day a new WIFI Motherboard was Couriered and all is functioning very well hence my FWU today. I reside in Cape Town by the way.

Hi There Cheryl, What is your issue with Mecer Inverter? Firstly we require the information that is on the side of your Mecer Inverter, secondly what type of battery or batteries you have, Lead Acid deep cell / Gel deep cell or Lithium. Lastly we will need the fault code that will show at the top middle of the Mecer Inverter screen.

Hi, Some of you have been asking about Battery settings wrt Hubble Batteries. Go to https://www.hubblelithium.co.za/sunsynk then at the top click on "Inverter Guides" choose your Inverter and see the correct Battery Settings. Hope this helps newbies

I would like to give an accolade to Revov Battery Backup Power Solutions Cape Town. I experienced an issue with one of the two Revov Batteries, this after almost 2 years. Contacted Revov, their friendly Technician Gert Inspected the battery, removed it for further diagnostics, after almost a week a decision was made to replace the battery with no questions asked. Not only replacing the battery but constant assistance after hours even on a Sunday morning (Thank you Dawie Revov Johannesburg) and (Thank you Gert Revov Cape Town) Brilliant service! Revov stick to their given warranty of 10 Years.

@Ali jutt I have since upgraded to another make 8.8kw Inverter now Ali however, @Coulomb is the the man that could assist, he his an absolute genius when it comes to Axpert/Mecer Voltronic Inverters and error codes (your case error code 90), perhaps your firmware needs changing. @Ali jutt Please specify what type of batteries you are using and SOC and float charge settings as well. This will determine the correct firmware @Coulombwill suggest which type of firmware you would require. Good Luck

Quite impressive indeed. I wonder what price it would be selling for? Very curious.

@Wittier Please if you will, upload your Inverter settings, if you are using WatchPower software, take a photo and let us look at your settings and firmware version. take a photo on the side of your Inverter it will have the Make/Model serial Number etc. for us to look at. lastly, the type of batteries you have connected, are they Lead Acid/Gel or Lithium. Important to determine the correct firmware to charge the type of batteries you have. Your Solar panel(s), how many do you have and what wattage each, they should be all identical in wattage or one or two may be higher in wattage, they will however lower themselves to the lowest Solar panel wattage. I'm pretty sure @Coulomb will ask the same questions as he is the professor of Voltronic Expert (Mecer) Inverters.

@87 Dream Fantastic news! I have two B100 5.2Kw Revov Lithium batteries already, sold my deep Cycle lead Acids December last year, so basically need to up the 4Kw Inverter and more Solar Panels. Thank you for the certificate the manual and added information you can send to [email protected] this will be my ammo to COCT I will stay in touch

@87 Dream OK! Shoo, My first and foremost I would think, to actually contact a person involved with Solar at COCT and discuss my upgrade and allow me to listen to his/her response, possibly test their integrity on the subject at full strength with regards to such, as you explained, my COC is on their registrar and to upgrade to a higher Kw should not be an issue...? Let me proceed with this and will update you as I receive answers, I will request an email explaining, or breakdown of residential requirements. My biggest challenge however is getting through to a person and this person hopefully answers their phone.

Thank you @87 Dream

Hi There @87 Dream. I need to ask a question seeing you are a Solar Installer and a good one too. I was chatting with a friend of mine and he warned me about compliant Inverters for the City of Cape Town (COCT) I will attach the list they permit us to purchase/use etc. Approved inverter and equipment ito NRS 097-2-1 (2021 06 18).xlsx (capetown.gov.za) COCT link to the PDF https://www.capetown.gov.za/Family and home/Greener-living/Saving-electricity-at-home/going-solar I'm not sure (confused really) as to whom these compliant Inverters refer to, Business? Corporate? or all Residential included. At present I have my Mecer (Axpert) 4Kw Inverter installed in 2015 and my COC was done 3 years ago, now I'm not sure if any attention was was made to the make of my Inverter by the person involved in the Solar Dept.at COCT, it being a Mecer and is mentioned in the list but it's not their required model Mecer? Perhaps that's why I have a COC now? I don't know. My query is, if I want to upgrade to the RCT-AXPERT MAX 8K-48V would I be in serious trouble? Meaning, should an Inspector arrive, he/she looks at my system and goes on to say my Inverter is not compliant, he/she gives me 7 days to remove it along with a 10K fine. Utterly confused. I am now looking at a Sofar Hybrid Inverter Buy Solar Inverters | Best Prices Online | Buy Now (solaradvice.co.za) because there are quite a few mentioned on the Compliance List. Should I go down that root? I have no idea how reliable Sofar Inverters are. Please, some advice would really put my mind at rest. Regards Confused
