What I noticed in several posts is that there is a common thing that this error appears at sunset or at 100% SOC or in cloudy weather. In other words, in these three cases we have a rise in voltage with a decrease in current. I think this causes a difference in current at the output of each inverter (taking into account that the efficiency of the internal components of the inverters is not 100% identical).

@Coulomb Thank you for your topic. Actually what you are saying is actually true, error code 72 is the current sharing error. I checked the current sharing cables as you mentioned, and I also checked all the connections, and they are all in good condition. I have done the upgrade that I talked about in my previous topic (make all solar panel strings for all inverters as equal voltage as possible). Until this moment, error 72 has not appeared again. I know this solution method doesn't make sense (at least to me 😅), but I hope to find help from those who have experience with inverter interior design in order to understand why this method works (for now).

Hi First of all, I apologize for the length, but I wanted to share all the details I have. - I have a system of 6 inverters (InfiniSolar 15K) in parallel, with a total of 50 kW of solar panels (the first unit is 2 String, and 1 String for each of the remaining units, 15 pv per strin, with about 634 volts), and 20 Lithium-ion battery (48V 96Ah) Note 1: With these details, we see that the inverters are not equal in capacity of the solar panels (the first unit is more than the rest of the units), yet the system works perfectly without any errors. Yesterday, I upgraded the system by adding about 20 kilowatts pv (distributed among 5 inverters, 1 String for each unit, about 416 volts). Note 2: With this upgrade, fault 72 started appearing frequently. What I noticed in several posts is that there is a common thing, which is that this error appears at the end of the day or at 100% SOC (this is what happens to me as well), and this is what prompted me to the following: (I know what I'm saying here doesn't make sense, but maybe this is the solution 😅) Tomorrow I will reconnect the new solar panels so that all the strings have the same voltage as the old strings (as much as possible), and I will let you know the results after making the adjustments my regards

@Coulomb This is generator. What is rang of frequency for Axpert MKSII 5KVA inverter?

Hi I have Inverter Axpert_MKSII-5KVA. When the utility is connected, the utility indicator flashes repeatedly without switching to line mode or charging batteries. utility parameters is : 220 V 48.5 Hz inverter settings is : 01 : UTL 02 : 60 A 03 : APL 05 : FLD 11 : 30 A 16 : SNU all other settings as default. help me please.

Thanks @Calvin Does this mean that the charging current will be split equally between the inverters? Because when I measured the charge current from the first inverter, it was 30 amps while in the second inverter it was 0 amps

Hi I installed two inverter (Axbert_Mksii-5kva) in parallel operation mode, and I set the maximum charge current to 50 ampere and the maximum charge current from the utility to 30 ampere. My question: Will the charging current be the total current of two inverter (maximum charge current 50 + 50 ampere, maximum charge current from utility 30 + 30 ampere)?

Hi The inverter 5kva (the specifications shown in the image) has been operating for two years normally, yesterday I found the inverter stopped, when I tried to turn it back on, all LEDs started to light and stop repeatedly without the inverter working, I checked and measured solar system components and found all the components normal. What is the possible cause of this failure?

Hi I installed an inverter Axpert_MKSII-5KVA, and after two days of operation the inverter stopped working and error 57 was displayed. Which means in the User Guide (current Sensor failed). What causes this error? How can it be fixed?

@Coulomb 230VAC

@Coulomb Thaks for your response. I did the measurement and it was 230vac, but the icon does not appear.

Hi My question about the inverter shown in the image. All parameters and settings have been confirmed and correct, but the utility input signal does not appear on the screen, and utility charging cannot be performed. Please Help

@Wilfred Thank you vray match

@Wilfred Gel batteries 200 AH

Hi Wilfred Thanks for your response Can you help me please for detailed steps of programming? What i should be do? Step by step please.

Hi I have 4 Axpert mks inverter 5kva, and i connected it as parallel, but i need help for detailed steps of programming it as parallel mode Single phase. And Should the order of inverters be considered? Help me please.
