Pylontech Inverter Settings

by Landon Blacket 30 May 2023

These are the settings requested by Pylontech to suit their 48V batteries (US3000B, US3000C and US5000B)

These settings are setup using a MK3-USB cable plugged into a laptop or remotely using the VRM. The Program required is VEConfigure downloaded from the Victron website downloads area

Charge Settings for Inverter/Charger are as follows

 

Charger tab:

Parameter Setting
Battery type Lithium
Charge curve Fixed
Absorption voltage 52.0 V
Float voltage 51.0 V
Absorption time 1 Hr
Note: make sure to double check the float voltage after completing Assistants, and if necessary set it back to 51.0 V.
Note For off-grid use: ignore the 'bms assistant required' warning.

Inverter Settings Tab:


VEConfigure Inverter Parameter Setting
DC input low shut-down 44V
DC input low restart 48V
DC input low pre-alarm* 48V
* The pre-alarm setting is dependant on your preference and on site specific requirements. You may wish for this to be activated earlier in an off grid situation to allow time to start a backup generator.
