MAX 50-100KTL3 LV Register address meaning
MAX /MAC/MID-X Modbus protocol type Download
Hold register address
It is related with settings of inverter,
Input Register address
It is related with running parameters of inverter.
Register Value
00
Meaning: Remote On/Off
ON: 1, OFF: 0
01
Meaning: SafetyFuncEn
Bit0: SPI Enable
Bit1: AutoTestStart
Bit2: LVFRT Enable 低电压穿越
Bit3: FreqDerating Enable When it enables, 91 register(Frequency Degrading point) address can be set.
Bit4: Softstart Enable 开机加载速率，每个机型都有
Bit5: DRMS Enable 澳大利亚电网调度指令
Bit6: PowerVoltageFunc : High voltage degrade , it is based on local utility safey rule
In the past , Bit0-3: for CE10-21 safety rule, Bit 4-6 for SAA. Now it has been cancelled.
02
Meaning: PF CMD memory state
Set Holding register address 3,4,5,99 CMD will be memory or not (1/0), If not, these settings are the initial value
03
Meaning: Active P Rate
Inverter Max output active power percent
Value: 0-100 or 255 ; 255: power is not be limited
04
Meaning: Reactive P Rate
Inverter Max output reactive power percent
05
Meaning: Power factor
Inverter output power factor’s 10000 times. If you want to set PF as 0.8, 0.8*10000 can be set on the register address
06 and 07
Meaning: Rated Power
06 register address: Normal power (high)
07 register address: Normal power (low)
Algorithm: (06 register address value * 2^16+07 register address value)*0.1w
(10*65535+44640)*0.1w= 69.999
08
Meaning: Vnormal
Normal work PV voltage
09 , 10 ,11
09: Fw version H Firmware version (high)
5449 ASCLL码等于TI
10: Fw version M Firmware version (middle)
312E ASCLL码等于 1.
11: Fw version L Firmware version (low)
3000 ASCII 码等于 0

Model number
| Model高位设置（A*B*D*T*) | 28 | 0-65535 | 工程模式的寄存器设置需转换成10进制（如A0B0D1T0)对应0x0010(对应十进制16），输入16 |
| Model低位设置（P*U*M*S*) | 29 | 0-65535 | 工程模式的寄存器设置需转换成10进制（如PFU1M3SA)对应0xF13A(对应十进制61754），输入61754； 设置28和29号寄存器需先发关机命令使逆变器处于非逆变状态； |

0是每一路不同的源，且每一路独立；2是输入并在一起，PV电压基本一致；取最大路MPPT电压的那一路控制
0 means different sources for each channel, and each channel is independent; 2 means the inputs are combined together, and the PV voltage is basically the same; take the control of the channel with the largest MPPT voltage
