For hundred-MW large-scale energy storage projects, full-time on-site O&M personnel can be assigned as required to take charge of daily operation, inspection records, local communication and on-site issue resolution.

Services include battery condition inspection, circuit fastening, thermal management & fire protection check, hidden risk investigation and parameter optimization; inspections are carried out monthly, quarterly and annually hierarchically.

Three modes are available: Owner self-operation (with our technical guidance), periodic inspection & maintenance, and full-site entrusted O&M; options can be selected individually or combined.

Upon warranty expiry, both parties can negotiate and sign extended warranty packages on demand with flexible options.

For failures caused by product quality issues during warranty period, remote troubleshooting, on-site maintenance, parts replacement and commissioning optimization are provided free of charge. For non-quality failures, only spare part cost and on-site service fee will be charged.
