1.0 – Introduction
This integration guide covers the recommended set up and configuration of Schneider Electric equipment
for optimizing performance with SimpliPhi PHI 3.8 kWh batteries. More information on SimpliPhi products
can be found on our website: https://simpliphipower.com/.
Schneider Electric offers many products which are too numerous to be covered here. The specific
Schneider products covered in this guide include, but are not limited to:
• Schneider Conext XW+ Inverter/Chargers
o Conext XW Pro
o Conext XW+ 6848 NA
o Conext XW+ 5548 NA
• Schneider Conext MPPT Charge Controllers
o Conext MPPT 60 150
o Conext MPPT 80 600
• Schneider Conext Battery Monitor
2.0 – Charge Controller and Inverter Settings
Schneider Electric has performed qualification testing of the PHI 3.8 kWh battery with their equipment.
Based on these combined tests and evaluations, the following parameters (refer to table below) have
been established. More information on Schneider Electric products can be found on their website:

3.0 – Battery Bank Sizing
A properly sized PHI battery bank should be at least double (2x) the kW rating of the inverter(s) and have
a C/2 rating greater than the maximum charge controller rating. Depending on the specifications of the
equipment used in the system, sizing the PHI battery bank based on these two criteria may yield different
results. Therefore, the best practice is to calculate the PHI battery bank based on both criteria and use
the greater of the two results as the minimum quantity. We can compare these two calculation methods
assuming the nomenclature below:
• Battery rated continuous power = Bat
kWh
(typically @ C/2)
• Inverter power full load = Inv
kW
• Maximum battery charge current = I
BatChrgMax
• PV charge controller maximum = I
PVChrgMax
• Recommended minimum number of batteries = B

3.1 – Discharge Calculation: Inverter Power Bank Sizing
To optimize the PHI battery bank and protect against over-discharge (voiding the battery Warranty), the
PHI battery bank should be sized at least double (2x) the kW rating of the inverter.
Discharge Example: B
#Inv
≥ Inv
kW
/ Bat
kWh
• Inverter is rated at 6.8 kW
• PHI battery is rated at 3.8kWh, therefore the C/2 load rating is 1.9 kW
B
#Inv
≥ 6.8 kW / 1.9 kW = 3.58
A properly sized PHI battery bank based on maximum discharge of the inverter would have a
minimum of 4 batteries. This ensures no greater than C/2 battery load. If the PHI battery bank has fewer
