ESS MAINTENANCE · ESS Full-Cycle Maintenance
ESS is more about
‘operation’
than installation
ESS is not just a simple electrical fixture. It is a high-risk, high-value facility that requires comprehensive management including batteries, PCS, EMS, BMS, system equipment, fire protection, and safety management. We provide integrated maintenance services that cover the entire lifecycle of ESS operations, including preventive inspections, performance management, safety diagnostics, and emergency response.

ESS operations
—aren’t these issues repeating?
The problem many operational customers face is not just simple failures, but the failure to detect anomalies early, which leads to significant losses.
01
Battery malfunctions cannot be confirmed by visual inspection or simple inspection
02
Delay in accurately identifying causes in case of integration errors between PCS/EMS/BMS
03
Difficulty in determining the actual risk and prioritization of minor repeated alarms
04
Constant anxiety for operators due to lack of a maintenance system
SolarLight addresses these issues not through simple inspections but through operational stability, preventive maintenance, safety management, and fault response systems.
Why Choose SolarLight for ESS Maintenance?
01
Prevention-focused maintenance
Repairing after a problem occurs is costly. Through regular inspections and analysis of driving data, we take proactive measures before problems escalate.
02
Minimizing operational losses
ESS stops time and is a loss. It centrally manages output drops, charge/discharge errors, and more, improving equipment uptime and operational stability.
03
Safety-Focused Approach
A safety-focused diagnostic system specialized for battery-based equipment such as battery degradation and temperature imbalance prevents the possibility of thermal runaway.
04
On-site Responsiveness
Practice is more important than theory! We operate a practical, field-oriented system that covers on-site inspections, cause analysis, initial actions, and follow-up responses.

FAQ
Frequently Asked Questions
We have compiled frequently asked questions about ESS maintenance contracts and operations.
Q1. Why is ESS maintenance essential?
ESS is a battery-based high-cost facility. Small abnormalities accumulate not only due to performance degradation but also to major fire incidents, making regular maintenance essential.
Q2. Can solar-connected ESS be managed together?
Yes, SolarLight possesses both solar O&M capabilities and provides an integrated understanding and management of power generation facilities and ESS.
Q3. Is it possible to contract with an existing installer separately?
Of course. Regardless of the installer, as a professional maintenance entity, we provide objective condition diagnosis and action recommendation services.
