PowerPlus Energy LiFe Series Manual

LiFe Series Battery Settings
for Victron Products
OVERVIEW
Settings listed are only applicable to battery charge and
discharge. All other settings are the responsibility of the
integrator.
It is the responsibility of the integrator to have a full
understanding of Victron products prior to programming, and it
is preferred that they have attended the manufacturer's training
or integration course should they be available.
Secondary Charge Source
If a Victron Solar Charge Controller is used with a MultiPlus
or Quattro, there can be some conflicts when charging due
to cable impedances and charger reaction times. In some
instances the displayed SoC can get stuck or create a conflict.
You may need to set MultiPlus or Quattro 0.3V below the Solar
Charge controller.
ESS Mode
If enabling Low SoC Shutdown (for ESS mode only) in Victron
Connect on the MultiPlus, ensure any charge controllers
are connected via VE Direct cables to a GX System monitor
otherwise SoC may be inaccurate and system may or may
not shutdown as required.
SoC Drift
State of Charge drift happens when the product that is
calculating SoC builds up an accumulative error. This error is
generally due to tolerance of components that measure voltage
and current, and algorithms used to calculate the SOC.
Most products will reset its accumulative error when the
system gets to 100% SoC or float.
It is important that a well-designed battery storage system
reaches float stage as regularly as possible, preferably every
one to two days to reset SoC drift.

SoC drift can be addressed in many ways.
Examples:
1. Sufficient solar sized to charge batteries to float
on the winter equinox.
2. Backup source installed (grid or generator) to allow
charging of batteries during extended bad weather
or high load events.
How many batteries do I need?
The table below outlines the required quantity of batteries to
achieve the full performance of listed Victron products.
The battery quantity is not compulsory, however it's highly
recommended as a minimum to reduce possible battery trips
due to over current.
For AC coupled systems, a minimum ratio of 2.5kWh (battery)
to 1kW (solar inverter) applies. See
Always consult and read the manufactures documentation
before designing, installing and programming their devices.
Important: LiFe4838P is not compatible with PWM
controllers
Please Note: These settings are for LiFe4838P batteries
with serials after LXXXX6000 only, please contact
PowerPlus Energy support for legacy settings.
LiFe4838P batteries with serials prior to LXXXX6000 are
not compatible with LiFe4838P batteries with serials
after LXXXX6000.
