Frequently Asked Questions (Q&A)
Q1: What is the difference between LFEC-1000-2080 and LFEM-500-1566?
A: The main differences are:

Feature	LFEC-1000-2080	LFEM-500-1566
Container Size	20 ft	20 ft
Rated Power	1000 kW	500 kW
Rated Energy	2088 kWh	1566 kWh
AC/DC Integration	AC/DC integrated	DC-coupled microgrid
STS Module	Optional	Standard
Application	Large utility, grid-scale	Microgrid, industrial parks

LFEC-1000-2080 is designed for larger power and energy requirements, while LFEM-500-1566 focuses on microgrid applications with STS included as standard.

Q2: Does the system support both AC and DC coupling?
A: Yes. The LFEC-1000-2080 is an AC/DC integrated container, meaning it supports both coupling methods:

AC coupling for grid-tied applications and retrofitting existing solar farms

DC coupling for new microgrids with direct DC connection of PV or wind

This dual-mode architecture gives you maximum flexibility for different project types.


Q3: Is the STS fast switching module included or optional?
A: According to the PDF specification table, the STS fast switching module is marked as "optional" for the LFEC-1000-2080. If your application requires millisecond-level on/off-grid switching (e.g., critical load protection, seamless island transition), we recommend adding the STS option.
For microgrid-dedicated applications, our LFEM series (e.g., LFEM-500-1566) includes STS as standard.


Q4: How long does it take to install and commission the system?
A: The LFEC-1000-2080 is a prefabricated, plug-and-play container. On-site installation typically takes 2-3 days for container placement, cable connection, and electrical integration. Commissioning and testing require an additional 2-3 days, depending on local grid connection requirements.

Q5: Can I expand the system in the future?
A: Yes. The LFEC-1000-2080 supports unlimited scalability. You can connect multiple units in parallel to increase total power and energy capacity. For example, two units can provide 2000kW / 4176kWh, and more units can be added as needed.

Q6: How does the liquid cooling system perform in hot climates?
A: The intelligent liquid cooling system ensures stable battery temperature even in extreme heat. Key features:
Operating temperature range: -20°C to 55°C
Active cooling maintains cell temperature difference ≤3°C
Full lifecycle management extends cycle life by 20%
For installations above 2000m or below -20°C, we offer customized thermal management solutions.


Q7: What communication protocols does the system support?
A: The system supports Modbus RTU (via RS485) and Modbus TCP (via Ethernet). It can be easily integrated with SCADA, EMS, or building management systems. Our cloud platform also provides remote monitoring and data visualization.

Q8: How does the system protect against fire?
A: The system incorporates multi-level fire protection:

Pack level: Each battery pack has its own fire suppression module
Container level: Cabin-level water spray fire protection
AI prediction: Continuous monitoring of voltage, temperature, and current to predict and alert potential faults before they escalate

Q9: What is the expected lifespan of the system?
A: The LFP314 cells are rated for 6,000 cycles at 25°C, 0.5C charge/discharge rate, 90% depth of discharge (DoD), and 70% end-of-life (EOL) capacity retention. Under daily cycling (once per day), this translates to approximately 15-16 years of useful life.

Q10: What is the typical payback period for this system?
A: Payback period depends on local electricity rates, load profile, and available incentives. Typical utility-scale applications (frequency regulation, peak shaving) see a payback period of 4-7 years. We provide a free ROI simulation based on your site data.


Q11: Do you provide remote monitoring and support?
A: Yes. Our cloud-edge collaborative platform provides real-time monitoring, remote control, OTA upgrades, and predictive maintenance alerts. Our engineering team provides 24/7 remote support for all installed systems.

Q: What is the kVA rating of the LFEC-1000-2080? How is it related to the kW rating?
A: The LFEC-1000-2080 has a rated AC power output of 1000 kW and a corresponding apparent power rating of approximately 1250 kVA (assuming a typical power factor range of 0.8-0.9 lagging/leading).

Parameter	Value
Rated Active Power (kW)	1000
Rated Apparent Power (kVA)	~1250
Max. Active Power (kW)	1100
Max. Apparent Power (kVA)	~1375
Power Factor Range	>0.99 (adjustable)
AC Voltage	400 V (three-phase four-wire)
Rated AC Current	1444 A

Note: The exact kVA value depends on the power factor setting. At unity power factor (PF=1.0), kW = kVA (1000 kW = 1000 kVA). At PF=0.8, the system delivers 1000 kW of real power while drawing / supplying approximately 1250 kVA of apparent power.
The system supports a wide power factor range (up to ±1.0, adjustable), allowing full four-quadrant operation. This makes the LFEC-1000-2080 suitable for both active power management (peak shaving, load shifting) and reactive power compensation (voltage support, power factor correction).



Q: How does reactive power capability benefit my application?
A: The LFEC-1000-2080's ability to provide or absorb reactive power (VARs) offers several benefits:

Benefit	Description
Power Factor Correction	Reduce utility penalties for low power factor by locally supplying reactive power
Voltage Support	Stabilize grid voltage at the point of connection, especially in weak grids or long feeders
Reduced Line Losses	Minimize I²R losses by reducing reactive current flow in cables and transformers
Increased System Capacity	Free up capacity in transformers and cables by compensating reactive power locally

This capability is particularly valuable for industrial facilities with large motor loads, welding equipment, or variable frequency drives (VFDs).
