MLT AND SOLAR MD
MLT inverters with Solar MD Lithium-Ion batteries have been tested and certified by both MLT and Solar MD R&D departments.
Both Products are locally manufactured in South Africa.
For this installation Logger V2 and active internet access during the commissioning is a requirement.
The maximum Charge and discharge power of the inverter should be considered.
Supported models via CAN BUS: Oasis (5h48 / 8H48) and Powerstar (10H) (model 2019)
For older Powerstar models please contact MLT support for setting up the charge/discharge limits via Relay 1 and Relay 2 of Logger V2.
Oasis Inverter
Oasis inverter range is a low voltage transformer based inverter, therefore a robust and safe product.
Trusted in the harshest environments in Africa.
Can Bus (500kbit/s) is used between Solar MD Logger V2 and Oasis , also requires MLT translator software for digital control
from the battery.
Minimum required hardware:
​
Battery modules required – 1x SS4074 / SS202 (7.4kWh) are installed per Oasis 5H48. Similarly 2x SS4074 / SS202 (7.4kWh) per Oasis 8H48. This is important due to the maximum discharge current of the Oasis.
​
​
CAN Communication:
​
For connection between Logger V2, Oasis and Nomad MPPT. Furthermore only the inverter must be connected to Logger V2.

Digital control Configuration – MLT Translator software on LoggerV2
​
Firstly on the Solar MD portal (http://login.mypower24.co.za) select Oasis Bridge on CAN 2:
login.mypower24.co.za Oasis Bridge
​
Menu path: My Devices → Logger → Interfaces →CANBUS 2.
​
Secondly choose Oasis Bridge and proceed with a software reboot on the Logger V2 in the Tab “System Settings”.
​
On the Oasis display enter the code “1918” in order to access the battery setup in the settings menu.
Choose “setup as lithium” and set the CAN bus speed to 500kbit/s.
Menu path: Settings → Battery Setup → Set up as lithium.
Finally, the standard settings are set to 80% battery Depth of Discharge during the day and the night.
You will be able to see the Solar MD logo, state of charge in “%” and kWh on the Oasis dashboard display.
Powerstar Inverter
​
Powerstar inverter range is a low voltage transformer based inverter, therefore a robust and safe product.
Trusted in the harshest environments in Africa.
Can Bus (500kbit/s) is used between Solar MD Logger V2 and Powerstar and requires MLT translator software for digital control
from the battery.
​
Minimum required hardware:
​
-
SS4074 / SS4037 / SS202 (minimum 2 x in parallel)
The Logger V2 interfaces with each Battery Management System as well as with Powerstar. Multiple inverter in parallel (read parallel Installation Guide). Multiple batteries in parallel are supported.
​
Minimum Battery modules required – 2x SS4074 / SS202 (7.4kWh) per Powerstar installed.
​
​
CAN Communication:
For connection between Logger V2, Powerstar and Nomad MPPT, only the inverter must be connected to Logger V2.

Menu path: My Devices → Logger → Interfaces →CANBUS 2.
​
Secondly choose Oasis Bridge and proceed with a software reboot on the Logger V2 in the Tab “System Settings”.
​
Settings can be changed on the Powerstar display.
​
The standard settings are set to 80% battery depth of Discharge during the day and the night.
