FBA10240 / FAB20480 Meter cupboard with power distribution system. TT, TN-C, TN-S, TN-C-S Loads, connected to EPS port, which need uninterrupted power supply Some unimportant loads 2.6.2 Declaration For EPS Function DANGER This product is not intended for supplying power to life-sustaining medical devices. Power outages may pose a risk to life when relying on this product for such purposes. The following statements outline our general policies concerning the ESS described in this document: 1: For the ESS, the electrical installation typically involves connecting the inverter to PV modules. In EPS mode, if there is no available power from batteries or PV modules, the EPS power supply will be automatically terminated. We bears no responsibility for any consequences resulting from failure to comply with this instruction. 2: Normally, the switching time for activating the EPS mode is less than 10 ms. However, certain external factors may cause the system to fail in EPS mode. Therefore, users must be aware of the following conditions and adhere to the instructions: Do not connect loads that require a stable energy supply for reliable operation. Do not connect loads whose total capacity exceeds the maximum EPS capacity. Do not connect loads that may cause high start-up current surges, such as air conditioners, high-power pumps, vacuum cleaners, and hair dryers. Battery current may be limited due to factors including temperature and weather conditions. Declaration For EPS Overload Protection In the event of overload protection, the hybrid inverter will automatically restart. If overload protection is repeatedly triggered, the restart time may increase (up to a maximum of 10 minutes). To avoid this, reduce the power of the EPS load to remain within the specified limits or remove loads that may cause high start-up current surges. 2.6.3 Energy Management NOTICE The battery discharges to provide energy to loads. If the battery is empty or there is not enough power from the battery system, the grid shall supply power to EPS loads and normal loads. When the grid is available, the hybrid inverter activates the bypass function. This allows the EPS loads to be directly connected to the grid via the integrated bypass switch in the inverter. If the Smart Energy Meter is either not present or experiencing abnormalities, the ESS will continue to operate normally. However, the battery will only be allowed to charge and not discharge. In this scenario, the feed-in power setting becomes ineffective, and the DO function for optimized mode will be disabled 12 flyfine User Manual Energy Management during Daytime The energy management system (EMS) defaults to self-consumption mode. The following scenarios illustrate the energy management process: Scenario 1: PV power generation > Load power consumption: - First,PV power is prioritized for the EPS loads first, followed by normal loads and then the battery. - If the battery is fully charged, any excess power will be fed back to the grid. The feed-in power will not exceed the feed-in limitation value set in the initial settings. Scenario 2: PV power generation < Load power consumption: - In this case, the battery will discharge to compensate for the energy shortfall. - If the combined power from the PV and battery is still insufficient to meet the load power demand, the inverter will draw power from the mains (grid) to make up for the deficit. flyfine User Manual Figure 2-6 EMS During Daytime Energy Management during Night During the nighttime period, energy management operates as follows: Battery Discharge: With available energy, the battery will discharge to provide power for the loads. It acts as the primary source of power during this time. Grid Power Supply: If the discharge power of the battery is insufficient to meet the load requirements, the grid will automatically supply power to the loads. This ensures a continuous and uninterrupted power supply, even if the battery capacity is depleted or unable to sustain the load demand. By combining the discharge capability of the battery and the EPS power from the grid, the system ensures reliable and continuous power supply during nighttime operations. 13 figure 2-7 EMS During Night During night, when the battery is empty, it will enter into standby mode. In this case, the grid will supply all power for loads. 3 Function Description 3.1 Safety Function 3.1.1 Protection Several protective functions are integrated in the ESS, including short circuit protection, grounding insulation resistance surveillance, residual current protection, anti-islanding protection, DC over-voltage / over-current protection, etc. 3.1.2 Earth Fault Alarm The device is equipped with a grounding fault alarm system. In the event of inadequate or nonexistent grounding on the AC side, an audible alarm will sound and the LED indicator will illuminate in red. 14 flyfine User Manual 3.2 Energy Conversion and Management The ESS efficiently transforms the DC power derived from either the PV array or the battery into AC power that meets the specifications of the grid. Additionally, it facilitates the transfer of DC power from the PV panel to the battery. Incorporating a bidirectional converter, the ESS has the capability to both charge and discharge the battery, ensuring optimal utilization of energy. To maximize the power output from PV strings that may have varying orientations, tilts, or module structures, the ESS employs multiple string Maximum Power Point (MPP) trackers. These trackers enable the ESS to extract the maximum available power from each PV string, thereby enhancing overall system efficiency. 3.2.1 Power Derating Power derating is implemented as a protective measure to safeguard the ESS against potential overload or faults. Moreover, the derating function can be activated in accordance with the requirements specified by the utility grid. Various situations that may necessitate ESS power derating include: Over-temperature conditions, which encompass both ambient temperature and module temperature. High input voltage levels. Grid under-voltage occurrences. Grid over-frequency events. Power factor deviations from the rated values. High altitude environments. For seamless integration with demand response capabilities, the ESS is equipped with a terminal block designed to connect to a demand response enabling device (DRED). This DRED facilitates the activation of demand response modes (DRMs). When triggered, the ESS promptly detects and initiates a response to all supported demand response commands within a swift 2-second timeframe. 3.2.2 Regular Operational Voltage Range The ESS are designed to operate effectively within the allowable voltage range for a specified observation time. The specific conditions for setting these voltage range parameters depend on whether the connection is for a normal operational start-up or an automatic re-connection following a tripping event triggered by interface protection. If the voltage level deviates from the defined operational levels, the ESS will disconnect from the grid within the protection time frame. In the event of a short-lived disturbance that lasts for a duration shorter than the required protection time, the ESS can automatically reconnect to the grid once the voltage level returns to normal operating levels after the disturbance subsides. 3.2.3 Regular Operational Frequency Range The ESS is designed to operate within its specified frequency range for a minimum observation time. The specific conditions for setting these frequency range parameters depend on whether the connection is for a normal operational start-up or an automatic re-connection following a tripping event triggered by interface protection. If the frequency level falls outside the defined operational range, the ESS will disconnect from the grid. In the case of a temporary disturbance that lasts for a duration shorter than the required protection time, the ESS can automatically reconnect to the grid once the frequency level returns to normal operating levels after the disturbance subsides. 15 flyfine User Manual 3.2.4 Reactive Power Regulation The ESS offers reactive power regulation modes to provide grid support. The specific reactive power regulation mode can be configured and adjusted through the SOLARMAN Smart App. 3.3 Communication and Configuration The ESS offers RS485, Ethernet, WLAN, and CAN ports for device and system monitoring. These ports allow configuration of parameters for optimal operation. ESS information is accessible through the SOLARMAN Smart App. The import power refers to the total power obtained from the grid, which encompasses the power used to charge the battery from the grid through the ESS, the power consumed by local loads, and the power supplied to loads connected to the ESS's EPS port from the grid. To comply with local regulations, it is necessary to calculate the maximum allowable system power based on the wire size and circuit breaker required for the selected model. This value can be configured as the Import Power Limit, which can be conveniently adjusted using the SOLARMAN Smart App. 3.4 Battery Management LiFePo4 battery are compatible with the PV ESs, further battery models will be made compatible in the future. To optimize battery lifespan, the ESS will conduct battery charging, discharging, and maintenance activities based on the battery status information received from the Battery Management System(BMS). NOTICE The suggested parameters provided in this section are subject to updates and revisions as a result of product advancements. For the most up-to-date information, please consult the manual provided by the battery manufacturer. State Definition To prevent excessive charging or discharging of the battery, three battery statuses have been defined based on different voltage ranges. Please refer to the table below for more details. NOTICE If the battery has remained unused or has not been fully charged for an extended period of time, it is advisable to manually perform a full charge every 15 days. This practice helps to maintain the battery's lifespan and optimal performance. 16 flyfine User Manual 3.4.1 Charge Management EPS Charge Management The purpose of the emergency charge management function is to safeguard the battery against damage resulting from prolonged excessive discharge. During emergency charging, the ESS is unable to respond to discharge commands.
