Honestly i dont know ... maybe it has only one. I am just trying to rewrite just in case it would solve my problem.

Hello Yes this is a clone of VMII Anyway i posted a post before about an inverter i purchased which is having an error 53. Anern 5.5kw inverter. I contacted the company in order to rewrite the firmware in case the problem is with the inverter firmware, since replacing parts did not do any repair. But they refused!!! They said they do not have it! So i figured out latelty that these companies are probably buying from NEXT company which is making a clone of voltronic company, so here i am trying to get the firmware

Hello guys, Anyone got the firmware of NMII plus 5.5kw?

Yes looks like this is a cheap clone of Axpert VMII, unfortunately. How much should be the voltage in order to transform it into AC? Yes i tried a lot to make them replace it. They are not cooperating at all. They just dont want to pay any thing. They even made me pay for the shipping of the parts 😄😄 Unbelievable.

Hello guys. I bought a solar inverter 5500 from anern company. The inverter came with an error 53. I applied to the company and they sent me these parts (i will attach them). I replaced these parts but the error is still. The problem is that the inverter takes DC voltage from battery and pv panels but does not transform it into AC. From AC source it is by passing the voltage. I tested the inverter, it is taking the battery voltage for example 48v and it is boosting it to 250v but in DC and it is not inverting it to AC. What should be done? Could it be a CPU problem? All capacitors and resistors and transistors look fine.
