Questions and Answers

Q1: How to ensure the stability of the system in extreme climates?

A: LFEC-5000 adopts a three-level temperature control design (liquid cooling of battery cells + air conditioning in the warehouse + external insulation layer), and ensures that the full-climate operation data meets the standards through -30°C low-temperature self-heating and 55°C active heat dissipation technology (providing a case in the extremely cold region of Alaska).

Q2: Compared with competitors, where does your cost per kilowatt-hour advantage come from?

A: Our cost advantage comes from three key factors:

The battery system cycle efficiency is increased to 92% (the industry average is 87%);

Containerized deployment reduces civil construction costs by 60%;

Intelligent operation and maintenance reduces the frequency of manual inspections (once a month → 4 times a year).

Q3: Does it support the transformation of old photovoltaic power stations?

A: Yes. We provide DC couplers to adapt to old inverters, and EMS is compatible with third-party photovoltaic monitoring systems (such as SolarEdge/SMA).

Q4: How to deal with sudden power outages?

A: The system is equipped with a 2C fast charging module, which can be fully charged to 20% in 15 minutes, and supports diesel generator linkage.
