Q1: How does RENA1000 come together? What is the meaning of the model name RENA1000-HB?
RENA1000 series outdoor energy storage cabinet integrates energy storage battery, PCS(power control system), energy management monitoring system, power distribution system, environmental control system and fire control system. With PCS(power control system), it is easy to maintain and expand, and the outdoor cabinet adopts front maintenance, which can reduce the floor space and maintenance access, featuring safety and reliability, rapid deployment, low cost, high energy efficiency and intelligent management.
Q2: What RENA1000 battery cell this battery used?
The 3.2V 120Ah cell, 32 cells per battery module, connection mode 16S2P.
Q3: What is the SOC definition of this cell?
Means the ratio of the actual battery cell charge to the full charge, characterizing the state of charge of the battery cell. The state of charge cell of 100% SOC indicates that the battery cell is fully charged to 3.65V, and the state of charge of 0% SOC indicates that the battery is completely discharged to 2.5V. Factory pre-set SOC is 10% stop discharge
Q4: What is the capacity of each battery pack?
RENA1000 series battery module capacity is 12.3 kWh.
Q5: How to consider installation environment?
Protection level IP55 can meet the requirements of most application environments, with intelligent air conditioning refrigeration to ensure the normal operation of the system.
Q6: What’s application scenarios with RENA1000 Series?
Under common application scenarios, the operation strategies of energy storage systems are as follows:
Peak-shaving and valley-filling: when the time-sharing tariff is in the valley section: the energy storage cabinet is automatically charged and standsby when it is full; when the time-sharing tariff is in the peak section: the energy storage cabinet is automatically discharged to realise the arbitrage of tariff difference and improve the economic efficiency of the light storage and charging system.
Combined photovoltaic storage: real-time access to local load power, photovoltaic power generation priority self-generation, surplus power storage; photovoltaic power generation is not enough to provide local load, the priority is to use battery storage power.
Q7: What are the safety protection devices and measures of this product?
The energy storage system is equipped with smoke detectors, flood sensors and environmental control units such as fire protection, allowing full control of the system’s operating status. The fire fighting system uses aerosol fire extinguishing device is a new type of environmental protection fire fighting product with world advanced level. Working principle: When the ambient temperature reaches the starting temperature of the thermal wire or comes into contact with an open flame, the thermal wire spontaneously ignites and is passed to the aerosol series fire extinguishing device. After the aerosol fire extinguishing device receives the start signal, the internal fire extinguishing agent is activated and quickly produces nano-type aerosol fire extinguishing agent and sprays out to achieve rapid fire extinguishing
The control system is configured with temperature control management. When the system temperature reaches the preset value, the air conditioner automatically starts the cooling mode to ensure the normal operation of the system within the operating temperature
Q8: What is PDU?
PDU (Power Distribution Unit), also known as Power Distribution Unit for cabinets, is a product designed to provide power distribution for electrical equipment installed in cabinets, with a variety of series of specifications with different functions, installation methods and different plug combinations, which can provide suitable rack-mounted power distribution solutions for different power environments. The application of PDUs makes the distribution of power in cabinets more neat, reliable, safe, professional and aesthetically pleasing, and makes the maintenance of power in cabinets more convenient and reliable
Q9: What is the charge and discharge ratio of the battery?
The charge and discharge ratio of the battery is ≤0.5C
Q10: Does this product need maintenance during the warranty period?
There is no need for additional maintenance during the running time. The intelligent system control unit and IP55 outdoor design guarantee the stability of the product operation. The validity period of the fire extinguisher is 10 years, which fully guarantees the safety of the parts
Q11. What is the high precision SOX algorithm?
The highly accurate SOX algorithm, using a combination of the ampere-time integration method and the open-circuit method, provides accurate calculation and calibration of the SOC and accurately displays the real-time dynamic battery SOC condition.
Q12. What is the smart temp management ?
Intelligent temperature management means that when the battery temperature rises, the system will automatically turn on the air conditioning to adjust the temperature according to the temperature to ensure that the whole module is stable within the operating temperature range
Q13. What does multi-scenario operations mean ?
Four modes of operation: manual mode, self-generating, time-sharing mode, battery backup，allowing users to set the mode to suit their needs
Q14. How to support EPS-level switching and microgrid operation ?
The user can use the energy storage as a microgrid in case of emergency and in combination with a transformer if a step-up or step-down voltage is required
Q15. How to export data ?
Please use a USB flash drive to install it on the device’s interface and export the data on the screen to get the desired data.
Q16. How to remote control ?
Remote data monitoring and control from the app in real time, with the ability to change settings and firmware upgrades remotely, to understand pre-alarm messages and faults, and to keep track of real-time developments
Q17. Does the RENA1000 support capacity expansion ?
Multiple units can be connected in parallel to 8 units and to meet customer requirements for capacity
Q18. Is the RENA1000 complicated to install？
The installation is simple and easy to operate, only the AC terminal harness and the screen communication cable need to be connected, the other connections inside the battery cabinet are already connected and tested at the factory and do not need to be connected again by the customer
Q19. Can the RENA1000 EMS mode be adjusted and set according to customer requirements？
The RENA1000 is shipped with a standard interface and settings, but if customers need to make changes to it to meet their custom requirements, they can feedback to Renac for software upgrades to meet their customisation needs.
