Maintenance Programs

Intervals aligned to asset condition and operating needs

Final scope depends on OEM guidance, contractual requirements, site procedures and equipment history.

Routine

Operational Inspection

Visual condition, alarms, housekeeping, obvious damage and abnormal indications.

Quarterly

Targeted PM

Selected equipment inspection, connections, filters, auxiliary systems and trend review.

Semiannual

Expanded Assessment

Broader inspection and selected tests based on equipment and site history.

Annual

Planned Outage Work

Defined preventive maintenance, testing and documented deficiencies.

Long-Term

Lifecycle Planning

Condition trends, component strategy and future outage recommendations.

Testing & Inspection

Field data that supports decisions

Results are most valuable when tied to equipment identification, operating conditions, photos and clear acceptance criteria.

Solar & BESS FAQ

Questions from asset owners and operators

Can you support corrective work on operating sites?

Yes. Scope is coordinated with site operations, access rules, LOTO requirements and approved equipment boundaries.

Do you perform insulation-resistance testing?

Yes, when the test is appropriate for the equipment and an approved procedure, voltage and acceptance criteria are established.

Can findings be organized into a report?

Yes. Photos, equipment IDs, readings, findings and recommendations can be organized for project and maintenance records.

Do you support both solar and battery-storage projects?

Yes. Electrical support can be tailored to PV field equipment, inverter/PCS systems, BESS auxiliary systems, transformers and related balance-of-plant equipment.
