BATTERY 119 · 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. With SolarLight’s accumulated expertise, it is safer and lasts longer.

ESS operations
— aren’t these issues repeating?
The problem many operational customers face is not just simple failures, but the failure to detectanomalies 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
05
No partner to respond immediately and take responsibility in case of a failure
06
Unclear Division of Responsibility Between Manufacturer and Contractor Delays in Action
07
Formal safety inspections lead to insufficient actual operational risk management.
08
Performance degradation, reduced up time, unexpected increase in repair costs
SolarLight addresses these issues not through simple inspections but through operational stability, preventive maintenance, safety management, and fault response systems.
What is SolarLight ESS Maintenance Service?
This is an integrated operations management service that regularly inspects the status of operating ESS, detects anomalies early, and, when necessary, links technical responses with on-site action.
01
Prevention of Safety Accidents
02
Shortened equipment downtime
03
Maintaining Efficiency and Lifespan
04

Customers requiring ESS maintenance
✓ Companies operating ESS in factories, logistics centers, and industrial facilities
✓ Power generation operators with solar-linked ESS
✓ Energy facility managers at public institutions and public enterprises
✓ Sites with a history of disabilities or safety concerns
✓ Places where insurance, safety inspections, and legal response management are needed
OPERATOR WARNING
In particular, ESS often accumulates minor operational issues after installation for 1~3 years, leading to performance degradation and escalating safety risks. A preventive maintenance system is far more important than post-failure repairs.
Prevent invisible economic losses.

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.
05
Group Integration Capabilities
By linking ESS operations, solar O&M, and battery diagnostics capabilities, customers can receive all integrated solutions through a single point of contact.

The purpose of ESS maintenance is to
prevent losses
✓ Prevention of safety accidents through early detection of abnormalities
✓ Minimization of equipment downtime and emergency repair costs
✓ Maintenance of equipment uptime and operational efficiency
✓ Reduced operator burden by strengthening responsibility management systems
ESS maintenance is not a service for restoring problems after they occur. It is an operational asset management service that detects signs before problems escalate, reducing losses and enhancing safety.

FAQ
Frequently Asked Questions
We have compiled frequently asked questions about ESS maintenance.
Q1. Why is ESS maintenance essential?
ESS is an expensive power facility and battery-based system. If minor abnormalities accumulate, they can lead to performance degradation, equipment downtime, and safety accidents, so regular maintenance is essential.
Q2. What is the diff erence between regular inspection and maintenance?
A regular inspection is the act of checking the current status. Maintenance is a concept that includes anomaly analysis, improvement recommendations, troubleshooting, and operational stabilization based on inspection results.
Q3. Can solar-connected ESS be managed together?
Yes, it is possible. Solarite can integrate and respond to power generation facilities and ESS in conjunction with solar O&M capabilities.
Q4. If a malfunction occurs, is dispatch possible?
Depending on the contract scope, remote verification, on-site dispatch, initial response, and coordination with partner companies are possible.
Q5. Can I also get a battery safety diagnosis?
Basic safety inspections can be included in the scope of maintenance, and more precise battery diagnostics can be supported in conjunction with the group’s specialized capabilities.
Q6. Is it possible to contract maintenance even if there is an existing installer?
Yes, it is possible. The installation and maintenance entities may diff er, and customized services can be proposed based on current operational status and history.
