Concept design
Define the proposed electrical architecture, key equipment interfaces and design basis early enough to support connection, pricing and project decisions.
Engineering design
Electrical design that is ready for the next project decision.
From concept through detailed and IFC issue, Renex develops practical design information for 30 kW–1.5 MW C&I solar PV, BESS and hybrid systems.

Design scope
Build the project around a controlled design basis.
Renex design work is intended to bridge the gap between an idea, a DNSP requirement and an installable electrical package — without treating those as separate technical worlds.
Detailed electrical design
Develop coordinated drawings, calculations, schedules and equipment information around the selected system configuration and site conditions.
Issue for Construction design
Prepare controlled construction information with clear interfaces, revisions and design assumptions for project delivery teams.
Design reports & deliverables
Produce supporting technical documentation where the project requires calculations, design notes, schedules, reports or specific network-facing information.
Technical delivery support
Resolve design RFIs, review proposed changes and keep the current engineering basis visible through construction and commissioning interfaces.
Typical design outputs
Documents built for real project use.
The precise drawing and calculation register is set by the project scope. Common outputs are structured for network review, estimation, procurement, construction and technical coordination.
SLD
Single-line diagrams
Electrical architecture showing the relationship between generation, storage, switchboards, protection, metering and the connection point.
IFC
Construction drawings
Controlled drawings and interface details prepared for the level of construction definition agreed in the scope.
SCH
Schedules & calculations
Cable, protection, equipment and other technical schedules or calculations required to support the detailed design.
Solar + BESS integration
Hybrid systems need more than two separate equipment designs.
Solar, batteries, site load, export control, backup objectives and protection interfaces need to be coordinated as one operating system. Renex keeps those interactions visible in the design basis.
- PV and BESS operating modes
- Site demand interaction
- Export and import constraints
- Backup supply requirements
- Protection and switching interfaces
- Metering and control interfaces
- DNSP connection conditions
- Constructability and delivery constraints
Design control
Clear issue status. Clear assumptions. Clear handover.
Renex is positioned around practical documentation and visible project control rather than vague “end-to-end” claims.
BasisKey assumptions and selected equipment are identified before detailed work proceeds.
InterfacesGrid, protection, metering, control and site interfaces are coordinated rather than left between disciplines.
RevisionDesign changes are controlled so the project team can distinguish current information from superseded decisions.
DeliveryConstruction queries are resolved against the design intent and the latest project constraints.
