Setting up ETP4830 A1 with Huawei OLT

For example, I will take the ETP4830 A1 power supply at 48V 15A (there is a model for 30A) and connect it to the MA5608T so that I can monitor the percentage of battery charge, set the correct parameters for charging batteries (default 53.5V floating and 56.5V accelerated) their capacity (the default is 40Ah or 65Ah), etc.

I ordered these blocks on Alibaba with delivery via Meest China.

To connect, I did not use a standard ethernet patch cord, but with such a pinout, the first column for MCUD1 in the OLT is a regular crimp for ethernet, the second for SMU01C or a similar module, for example PMU11A, EPMU03:

1 (white-orange)7 (white-brown)
2 (orange)8 (brown)
3 (white-green)
4 (blue)1 (white-orange)
5 (white-blue)2 (orange)
6 (green)4 (blue)
7 (white-brown)
8 (brown)

The ETP4830 A1 (SMU01C) has a default flow rate of 9600 and address 0, if it is different on the OLT, then you can set 19200 using the buttons through the display on the SMU01C (default password is 000001) or execute the command on the OLT:

emu baudrate 9600

Add emu:

emu add 2 smu 0 0 "SMU01C"

Let’s see the status:

display emu 2

  EMU name    : SMU01C
  EMU type    : SMU
  Used or not : Used
  EMU state   : normal
  Frame ID    : 0
  Subnode     : 0

If everything is OK, the status is “normal” and not “fault”, then let’s move on to managing the added emu:

An example of changing parameters, with a question mark, let’s see which parameter needs to be specified, since the order of specifying parameters on different devices is different:

power battery parameter ?
power battery parameter 1 0.10 60 65

Battery group num, default 1 (0-2) (0 – if batteries are disconnected)
Power battery charge limit quotiety, default 0.15 (0.05-0.25)
Equalizing charge time, default 60 days (30-240)
Battery group 0 capacity, default 65, unit is AH (5-1000)

If the batteries are less than 65Ah, then we will indicate the correct capacity and the correct charge factor, otherwise they will be charged with a large current and may swell after a while. For example, multiply the capacity by the charge factor and get the charge current: 100Ah*0.10=10A. It is advisable not to exceed a tenth, for example, for a capacity of 65Ah, the charge current is a maximum of 6.5A, if you specify less, then the batteries will take longer to charge.

An example of setting voltage and battery charging mode, humidity and temperature alarms:

power charge ?
power environment humidity ?
power environment temperature ?

Specify the date of installation of the batteries:

power batteryinstall 2023-03-10
display power batteryinstalltime

Battery test parameters:

power battery-test simply-test start
display power battery-test info all

Exit the configuration mode and save the configuration:
