•The unit contains capacitors that remain charged to a potentially lethal voltage after
the mains, battery, and PV supply have been disconnected.
•A hazardous voltage will be present for up to 5 minutes after disconnection from the
power supply.
•CAUTION - RISK of electric shock from energy stored in a capacitor, never operate on
the inverter couplers (plugs), the mains cables, battery cables, PV cables, or the PV
generator when power is applied. After switching offthe PV, battery, and mains,
always wait for 5 minutes to let the intermediate circuit capacitors discharge before
unplugging the PV DC, battery connectors, and mains couplers.
•When accessing the internal circuits of the inverter, it is very important to wait 5
minutes before operating the power circuit or removing the electrolyte capacitors
inside the device. Do not open the device beforehand since the capacitors require
time to sufficiently discharge!
•Surge protection devices (SPDs) for PV installation:

Freedom Won Three Phase Encore 12K and Encore 15K Inverter Manual Version 0
Page 5 | 41
WARNING!
Over-voltage protection with surge arresters should be provided the PV power system
is installed. When The grid connected inverter is not fitted with SPDs in both PV input
and mains input
•Lightning will cause damage either from a direct strike or from surges due to a nearby
strike.
•Induced surges are the most likely cause of lightning damage in majority of
installations, especially in rural areas where electricity is usually provided by long
overhead lines. Surges may originate on both the PV array conductors and the AC
cables leading to the building.
•Specialists in lightning protection should be consulted during the end use application.
•Using appropriate external lightning protection, the effect of a direct lightning strike
into a building can be mitigated, and the lightning current surge can be discharged into
the ground.
•Installation of Surge Protection Devices (SPDs) is recommended to protect the
inverter against mechanical damage and excessive stress. Including a surge arrester
in case of a building with external lightning protection system (LPS) when separation
distance is kept.
•To protect the DC system, SPD type2 should be fitted at the inverter end of the DC
cabling, if the voltage protection level (VP) of the surge arresters is greater than 1100V,
an additional SPD type 3 is required for surge protection for electrical devices.
•To protect the AC system, SPD type2 should be fitted at the main incoming point of AC
supply (at the consumers breaker), located between the inverter and the
meter/distribution system.
•All DC cables should be installed to provide as short a run as possible. Positive and
negative cables of the string or main DC supply should be bundled together. Avoiding
the creation of loops in the system.
•Spark gap devices are not suitable to be used in DC circuits once conducting, they won’t
stop conducting until the impedance voltage across their terminals is typically more
than 30 volts.
•Anti-Islanding Effect
Islanding effect is a phenomenon where a grid-connected PV system can still supply power to
the nearby grid when the local grid is off. It is dangerous for maintenance personnel and the
public.
The Encore Three Phase series inverters provide Active Frequency Drift (AFD) to prevent the
occurrence of islanding.
•PE Connection and Leakage Current

Freedom Won Three Phase Encore 12K and Encore 15K Inverter Manual Version 0
Page 6 | 41
The end-use application shall monitor the protective conductor using the Residual Current
Operated Protective Device (RCD) with rated fault current Ifn≤240mA which automatically
disconnects the device in case of a fault. The device is intended to connect to a PV generator

3. Introduction
3.1. Basic Features
The Encore 12K and 15K three phase inverter series is a high-quality inverter range that can:
•Convert solar energy to AC energy,
•Store solar energy in batteries
•Use battery stored energy to supply the AC output without the grid being available,
•Export excess solar energy to the grid,
•Use the grid to charge batteries if needed,
•Use the grid to support loads directly if needed,
•Interface with a fuel generator for backup power if needed.
•The inverter can be used to optimize self-consumption, store in the battery for future
use or feed into public grid. Work mode depends on PV energy and user’s preference. It
can provide power for emergency use during the grid lost by using the energy from
battery and inverter generated from PV.
System Diagram
The Encore Three Phase inverters apply the wiring rules that require the Live line and N (Neutral)
line of EPS to be disconnected from the Live line and N (Neutral) line of the grid input (applies
to most countries).

Note!
•Please control the home loads, and make sure it’s within the “EPS output rating” under
•EPS mode, otherwise the inverter will Shut down with an “overload fault” warning.
•Please confirm with the mains grid operator whether there is any special regulations for grid
connection.
•The wiring diagram is for reference only, and the complete electrical connection shall meet the
requirements of local regulations.
•Ensure correct phase sequence.
If the user requires more loads to be placed on the EPS that could exceed the power rating of
the inverter, the user must request a larger model inverter, or place multiple inverters in
parallel.
Note!
•The peak load power must not exceed the rated output power on the
Load 1 and Load 2 connections. The load profile at the premises must be
assessed before selecting the inverter size, or larger loads must be
connected on the Load 3 connection point (non-backup). The inverter
will shut down with an “overload fault” if the loads exceed the rated
power.
•Comply with the local power utility regulations for grid connected
systems.
