@Coulomb @KLEVA Battery Equalizer 2 off

Hi @Coulomb @KLEVA, Coulomb about my Control Board it is what I was told at the counter when receiving my Inverter.🤨 I will consider flashing 73.00e after the silly season. and once again thank you for replying. My Batteries are Deltec 105ah sealed Lead Acid 1250 Highcycle I have taken some pics. On the 4X4 forums they are highly recommended for their durability and almost run flat situations and recharge rather quickly, for my use I am told they will give me quite a few years 5/6 🤷‍♂️ I'm not sure. Bought two Battery Equalizers one for each bank of 4 connected in series, which is now 210ah. 🤔

@Coulomb Hi Coulomb, Just a heads-up on my Inverter, collected it on Thursday and connected yesterday. The Mecer Technician mentioned whilst Flashing the new Firmware to the Control Board, heaven forbid Load Shedding started unabated and corrupted the Control Board in the middle of the Flashing 😤 So, I have a new Control Board and Firmware which by the way, was sent from Voltronic as the correct firmware for my model Inverter 72.61. lastly I was not charged a cent for the work done 😃 If you will Coulomb, please check my WatchPower settings, (attached pics) today is a cloudy day my charge settings is Utility and Solar. Dishwasher heating came on hence the high percentage load.

@Cef Hi Really good work and a great effort you have put in the software.

Hi Coulomb, My guess is when the electrician (The first one) who got me out of darkness possibly and more than likely moved more wires around than what he told me. The Inverter wires were not touched. I am just glad that I am back to Solar 😊, we are now experiencing Stage 6 Load Shedding meaning, 2 1/2 Hrs in the Daytime and 2 1/2 Hrs at night 😩 Happy Man now

Hi Coulomb, AT LAST! The Solar Installer came to the house last night and he practically flipped his lid when he saw my DB Board. He connected the wiring correctly as you suspected and VOILA! The Inverter is working as it should 😂. See the pic of the wiring now, compare it with the previous one, a huge difference. AC/ Hz is at 50Hz all good now. I will have to phone Mecer and tell them the story. Again thank you for your patience with me Coulomb and I hope others on the Forum will take heed from my 2 week anguish.

Hi Coulomb, My Inverter went to Mecer for the Flashing Green LED and possible Control Board replacement. A friend of mine that has a 48v Inverter, a Proline Energy told me I can use it, as he doesn't have enough panels for it and I can have power whilst Load Shedding takes place. Sadly, his inverter shows exactly the same symptom as my Mecer was showing. Now, going back to "Error 90" I was unable to obtain power on that day from the inverter as well as NO Eskom mains supply and it was getting dark quickly, I called an Electrician friend of mine to please help me out and put mains power on. He told me he only removed the Black and the Red at the bottom of the Alternative Supply CB and Eskom Mains power to the house was on. At that time I still had my Mecer Inverter and after disconnecting its power my decision was take my Mecer to Mustek for Control Board check and Firmware. Upon acquiring my friends Proline Inverter, I temporarily connected the Inverter the same way as my Mecer as they are identical (I took photographs of the wiring). Then I asked the Electrician over the phone (as he was working on site), to be sure what to connect the Red and Black wires and which colour to colour at the CB (Live is Yellow to Red neutral is Black to Blue) Ever since then I have this Flashing green Led light and Mains symbol flashing with no power to the house, the same as what the Mecer was doing after removing error code 90 and all those firmware changes. The batteries are being charged by the Solar Panels but for some reason only reach 93% and never 100% in the state the Inverter is in at the moment. So, I wait for an answer from Mecer for my Inverter results and hopefully the Solar installer will arrive and look at my DB board.

Hi Coulomb, I am now in communication with a Solar installer, hopefully they identify the problem as you have mentioned, I really appreciate your time trying to help me and pointing me in the right direction. You rock and the people on the Forum. I will keep you posted.

Hi Coulomb, Thank you for that observation, I will definitely chat with my Electrician who installed the DB. My suspicion has always been related to the DB. Will get back to you on tomorrow, thanks once again.

Hi Coulomb, Whst should the AC frequency be ideally? I'm thinking of replacing the Inverter circuit breaker at the DB board...?

Hi Coulomb, I tried the UPS setting, no change, the Power is still off due to load Shedding as I type. As well set to Charger source priority Utility first and Output source priority Utility, no change AC Green LED flashing??

Sorry Java Script was blocked by my Browser 😤 On the DB Board "Alternate Supply" is the Inverter Circuit Breaker, maybe you can see something??🤔

Hi Coulomb, I am unable to upload pictures??

Hi Coulomb, When I switch the Circuit breaker off, it is the Breaker in the house DB board for the Inverter. I made quick video clips to show you https://youtu.be/jh4ECtSlim8 https://youtu.be/DbiiQa8nKOI As I type we have Load Shedding, the Output on the Inverter is 230v with no Power to the house??. Circuit Breaker in the house DB board is up, measured the voltages at the Circuit Breaker, top and bottom 230v. Just so you know I am not an Electrician but I try please be patient with me LOL!

@Coulomb A good friend of mine has helped out with a Proline Inverter which is exactly the same as my Mecer. NOW...! This Inverter is showing the exact same symptom as the Mecer. Utility Input connection reads 230v Output Connection 230v .In the pic of WatchPower the Utility flashes 5 times, the battery charge percentage remains at 91/92. I am completely lost to what the issue can be. When I switch the Circuit Breaker off for the Inverter, Utility Input 0v Ouput 230v . I will probably receive a call from Mecer informing me that there is nothing wrong with my Inverter, 😩 What makes it worse, we have Stage 4 Load Shedding which can continue till God knows when.

OK, Disconnected the Inverter and going to drop off at Mustek Mecer Agents for Control board replacement, Will keep you posted.

Good Morning Coulomb, I have switched off the Inverter and Solar Panels, when the sun comes up I will switch on again to give the batteries a tickle for an hour or so. I am back at work today and actually achieved nothing to fix the Inverter issue yesterday. So, at 8am this morning I will phone Mecer for any news received concerning my dilemma. A chap I'm dealing with at Mecer Craig, is mentioning that my Control Board, in all likelihood will need to be replaced, Firmware changing has not helped but allow the Utility input to show 230v with no Output at all and the flashing 90 has turned to a flashing Utility Symbol. 😩 My fear is the cost of this Control Board? To be fair, there was absolutely nothing wrong with the Inverter until I purchased the new Deltec Batteries and being told to update the Firmware from Mecer to 74.40p. I don't think Mecer or anybody else would have guessed "In 60 days time" I'll sit with a bricked Inverter. 😫 Now, Mecer is waiting for Voltronic Taiwan for a solution, seriously hope at their expense.

@Coulomb I actually followed the Flashing SOP when at the end of Flashing, it tells you to restore to defaults then reintroduce the settings for the batteries. All the flash versions I performed I followed the SOP. Now stuck with version 74.40p this time no "90 error" but a flashing Utility symbol, this is what I got with the other versions. I will try again. I only use WatchPower. Shall I restore defaults first then install 72.20? 73.00e cut off my Solar symbol to just a square

Aaah well. As soon as Mecer receives the fix for me, I will gladly share it with you and who ever has this issue it's what the Forum is all about. Thanks for replying Coulomb

@Coulomb OK will send you my sticker

@Coulomb OK Mecer came back to me and asked that I flash again the firmware they sent me 74.40p, it will go 60 days again but should work. Sadly, I'm back to where I was with all my settings including Equalization BUT the Flashing Utility is still there with no power to the house only Utility Powering the house. Solar Panels charging the batteries.

@Coulomb I have no clue at all, Mecer is waiting a reply from Voltronic Taiwan. Not sure what to do.

OK, Re-flashed to 72.70 I have the Solar Panel symbol back but the Utility symbol still flashing 5 times with the buzzer going off with no power to the house from the Inverter, only Utility powering the house. When taking the photo the Utility Symbol was flashing, not seen in the pic had to mute the buzzer.
