Page 9: Introduction
The Freedom Won Encore HPS models are specifically prepared for superior compatibility with the range of Freedom Won HV and HV+ batteries as applicable as well as the powerful and versatile Freedom Won EMS. All Encore HPS plants should include a Freedom Won EMS for optimal control and monitoring.
Page 10 This manual provides Freedom Won Encore HPS features, installation, operation, maintenance, and troubleshooting information for the trained installer and operator. For safe and proper installation of the Freedom Won Encore HPS, installers and users must possess a comprehensive understanding of electrical theory and be familiar with electrical equipment and wiring.

Page 13: Hps Features And Advantages
• Expandable photovoltaic controller power for flexible configuration. • Strong three-phase unbalanced load capacity in off-grid mode. • Power frequency design with high impact resistance. • Dual-channel auxiliary power supply with redundant design for improved reliability. Copyrights reserved by Freedom Won Contact us: www.freedomwon.co.za...
Page 14: Encore Hps Basic Functions
In off-grid mode, the Encore HPS takes control of the microgrid by regulating both voltage and frequency to ensure a stable and reliable power supply. The energy storage converter operates independently to provide power in the absence of the grid, as illustrated in the example below. Copyrights reserved by Freedom Won Contact us: www.freedomwon.co.za...

Parallel Connection In large-scale applications, the Encore HPS inverter can be connected in parallel to improve system redundancy, capacity, and reliability. A maximum of four (4) units can be connected in parallel. Copyrights reserved by Freedom Won Contact us: www.freedomwon.co.za...
Page 16: Figure 4: Parallel Connection Example
Figure 4: Parallel Connection Example When operating in parallel mode, it is essential to complete the parallel connection setup process before applying the load to the HPS. Failure to do so may result in system failure. Copyrights reserved by Freedom Won Contact us: www.freedomwon.co.za...

Page 18: Over-Temperature Derating Operation
• The MPPT module uses a three-level topology, which improves conversion efficiency. 3.3.6. Over-Temperature Derating Operation The Encore HPS operates within an ambient temperature range of -30°C to 55°C. If the temperature exceeds the limit, the Encore HPS will derate its performance.

Page 27: Freedom Won Hv Battery Compatibility
Freedom Won HV Battery Compatibility The Encore HPS50, 100 and 150 models must be matched with Freedom Won HV batteries. The HV+ batteries are not suitable for these Encore models because the higher battery voltage will disrupt the buck conversion from string voltage to battery voltage by leaving insufficient voltage gap between the battery and the strings.
Page 28: Encore Hps Modes And Functions
Mixed Mode, and Manual Mode. Users can select the most suitable mode based on their needs. These modes are only applicable when the Freedom Won EMS is not used because the EMS will control the required mode and logic where it is installed. The EMS modes operate similarly to the built-in modes but offers much more control and versatility.
Page 29: Figure 12: Control Dg Power Through Ems Scenario
Only when the load's energy demands are fully met the excess energy will be used to charge the batteries. Once the batteries are fully charged, if the PV system continues to produce more electricity than the load requires, the solar output will be limited. Copyrights reserved by Freedom Won Contact us: www.freedomwon.co.za...
Page 30: Battery Priority Mode
2. When the battery reaches minimum gen start SOC, the generator will start and supply power to the load and charge the battery. If gen is not available, the inverter will stop discharging on the battery's low cutoff SOC, which is 10% for Freedom Won batteries. Figure 15: DG Supply to Load a.
Page 31: Figure 16: System Charges Simultaneously
3. When PV power is insufficient to fully charge the batteries, the system uses the available PV power for charging, supplements the remaining energy needed from the grid, and simultaneously powers the load from the grid. Figure 18: PV Power Limited Copyrights reserved by Freedom Won Contact us: www.freedomwon.co.za...
Page 32: Figure 19: Pv Power Limited
There are six possible scenarios: 1. When PV power is sufficient, the system prioritizes powering the load and uses any excess energy to charge the batteries. Figure 21: Charging State Copyrights reserved by Freedom Won Contact us: www.freedomwon.co.za...
Page 33: Figure 22: Pv Power Shortfall
4. When PV power is not enough to charge the battery, the PV and diesel generators work together to charge the battery, and the load is powered entirely by the diesel generator. Figure 24: PV and Diesel Charging Battery Copyrights reserved by Freedom Won Contact us: www.freedomwon.co.za...
