I´ve got some Growatt MIC inverters (2pc MIC600T-LX and MIC2000T-LX) and I was wondering long time, if they are the same inverter with just different output limits.
Specs seems to be the same: Max DC Voltage 500V, MPP-Range 50V-500V, Max current 13A, same weight, same dimensions.
A tear down showed me, same wire gauge inside, same boards. A newer one just had the additional AFCI-Board.
There are the same amount of IGBTs on all boards I´ve got. BUT I was´nt able to get them released off the heatsink, to see if the are the same kind.
A newer one has different power-plug and different manufacturer of capacitors.
Does anyone have experience, what kind of IGBTs Growatt uses or does know, how to remove?
The only difference seems to be in the so called Mode of the inverter.
You can see it on the inverter-display "More Info", in shinephone app or server.growatt.com
It´s divided into 7 parts: S07 B08 D00 T00 P0F U01 M0006 - most of the parts are described here.
Part M is for output section. Readings of different inverter types gives following hex digit results:
M0006 - MIC600, M0007 - MIC750, M000A - MIC1000, M000F - MIC1500, M0014 - MIC2000 - other series inverters seems to have other digits in this part, as you see in the link for the parts above.
It's changeable in different ways:
Shinebus with RS485-adapter - videolink - link to software in the comments under the video.
you need to set the inverter to standby
after that you can change the M-Part under settings
Inverter reboots with the new power-setting
If you have shineWifi and a Growatt-account you can change it by modifying register 121 on server.growatt.com - see the above link under parts. It's the same procedure. But digits have to be decimal. 6 for MIC600, 7 for MIC750, 10 for MIC1000, 15 for MIC1500, 20 for MIC2000.
set register 0 to 0 for standby - then set register 121
At least you can change it with any connected modbus-master - in some case the register may differ by +1 - some master application have different start addresses.
I think you will lose your guarantee by changing this and if you use it connected to the grid it may effect local regulations.
At least I don't know what's inside YOUR or later build inverters - I´ve just teared down my own and do use it off grid.
For now these seem to work with higher output. I don´t know, how long they do.
