SCOPE GAPS
Equipment lists do not always define interfaces.
Ratings, terminations, auxiliary loads, protection signals and communication points must be aligned across the approved equipment scope.
PV POWER PLANT EQUIPMENT INTEGRATION
One Technical Scope for the Complete PV Power System
H&D POWER coordinates PV modules, inverters, step-up transformers, switchgear, protection, SCADA, PPC, cables and optional BESS under one approved technical scope.
01 · OVERVIEW
Independent equipment integration around the live project requirements.
Equipment is selected against the SLD, grid requirements, approved vendor list, environmental conditions, delivery plan and total project risk—not a single factory’s catalogue.
H&D POWER coordinates multi-brand equipment, engineering interfaces, technical documentation, FAT support and export delivery through one project window. Final inclusion is defined in the approved technical and commercial scope.
02 · CUSTOMER CHALLENGES
Reduce multi-vendor interface risk before manufacturing.
DOCUMENT CONTROL
Supplier drawings arrive on different timelines.
Technical schedules, deviation records, drawings and interface data require coordinated review before release.
DELIVERY RISK
Factory and project milestones must stay connected.
Inspection, FAT, packing, export documentation and delivery timing must follow the agreed project requirements.
03 · INTEGRATED EQUIPMENT SCOPE
From PV generation to the MV and plant-control interfaces.
Each item is included only where stated in the approved project scope.

04 · ENGINEERING INTERFACES
Align DC, AC, primary, secondary and communication interfaces.
DC and inverter interface
Module string data, combiner arrangement, inverter inputs and DC protection requirements.
AC and step-up interface
Inverter output, transformer ratings, impedance, vector group, auxiliaries and cable terminations.
MV and protection interface
Collection topology, switching duties, protection philosophy, metering and interlocking.
SCADA, PPC and gateway interface
Signal lists, communication protocols, time synchronization, plant control and utility data points.
05 · PROJECT WORKFLOW
Controlled review before equipment release.
RFQ Input ReviewScope ClarificationEquipment SelectionInterface ReviewDocument ApprovalQA & FAT SupportExport & Support Coordination
06 · QUALITY ASSURANCE & FAT
Inspection and testing follow the agreed project scope.
Integrated FAT can be arranged at an approved manufacturing or complete-set partner facility, subject to project scope, facility capability and the agreed FAT procedure.
Standard FAT activities expressly listed in the commercial offer are included in the quoted scope. Third-party inspection, customer travel, special tests, non-standard facilities and repeated testing caused by scope changes are quoted separately.
07 · GRID-CONNECTION SUPPORT BOUNDARY
Technical support does not replace statutory local authority.
H&D POWER provides equipment integration, technical documentation, interface coordination, FAT support and commissioning assistance within the contracted scope.
Formal grid-connection approval, statutory engineering design, construction licensing, local certification and utility authorization remain the responsibility of the project owner and appropriately licensed local parties unless expressly included through an approved local partner.

09 · PV PROJECT RFQ
Submit the available project inputs.
Initial acknowledgement and input review target within 24 hours after sufficiently complete project information is received. Initial scope breakdown and budgetary quotation target within 48 hours, subject to sufficiently complete project and pricing inputs. Neither target is a final quotation or approved design.
