Friend I am with a new powmr inverter bought from china I am in brazil and when I connect it presents error 06 and has no voltage output I am a technician in the area of televisions have opened and checked nothing burned nothing short power as I do not know this equipment I am in search of informacoens would have any suggestions for me
hello sir, thank you very much, it was a very useful video. I would like to ask something. I have the same one and I can't get an output when normal 220 v ac is input. Did you encounter such a malfunction? what can i do? thank you very much in advance
Hello sir.. Bought a must pv1800 pro 2 weeks before. And using grid charging method till now with lead acid battries. In 2 or 3 days i noticed some issue with it in showing the battery charging current. The inverter shows -1 amp to the battery though the the battery is fully charged and charging led also turned off. I turn the solar only charging and discconect the solar but it still shows -1amps. It will set to 0 when i discconect it from the gird. And turn again -1 when i conncted. But when i disconnect the battery and reconnect and works fine about 2days and it happen again. Anything that i can check ? I contacted must and they said they ask from the enginner since the unit is still under warranty.
@@ALayoubiMaintenanceCenter but when i connected thourgh the mutimeter it dont show any current inflow.. and charging circuits are off at that moment...
@@ALayoubiMaintenanceCenter also i put the inverter into solar only charging mode and disconnect solar input .. it shows the same -1 but the battery voltage is dropping gradually to the idle from the floating
If the inverters are new slow and weak software For some devices, it causes errors on the screen. What if the inverter is old? The cause of the measurement error must be found in the internal components

Keep on with the good work of sharing knowledge
Great work ... Please.. Can you explain for us how to get on schematic for this inverters ??
Thanks
You are a great engineer👍👏
NIce repair well done
Hi there friend, I also have error 05. I checked the IGBTs and the 10ohm resistors and they look good. Do you have any advice on what to check next?

Hello. Do you have cpu for must 1 kw / 3 kw ?
We are so sorry
We have not any cpu for must Inverters

Anything that i can check ?
I contacted must and they said they ask from the enginner since the unit is still under warranty.
I think everything seems normal.
Even if the batteries are full, they need to charge a low ampere
For floating
