PowerPlus Energy LiFe Series Manual

LiFe Series Battery Settings
for Solis Inverters
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 the connected PCE prior to programming,
and it is preferred that they have attended the manufacturer's
training or integration course should they be available.
SoC Drift
State of Charge ("Soc") 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 rest 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?
Minimum battery size should be greater than the rated peak
output of the inverter.
Battery to PV ratio is no less than 2.5kWh (battery) : 1kw (PV).
The battery quantity is not compulsory, however it's highly
recommended as a minimum to reduce possible battery trips
due to over current.
Always consult and read the manufactures documentation
before designing, installing and programming their devices.
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.
