Development Scope
Device and interface access
Adapt the authorization agreement of the inverter and electric meter, configure the device address, power generation rate, operating status, fault code and collection cycle.
Product business functions
Adapt inverter and meter protocols, develop power generation, operating status, fault collection, multi-device polling and platform data synchronization.
Platform and data connection
Combined with the business link of main controller and instrument → data and order status → 4G → enterprise operation platform → operation and maintenance processing, the device identity, data fields, update time, abnormal status and result confirmation method are defined.
Exception handling and operational constraints
The cumulative amount of power generation and periodic power need to be unified; the writing and control of equipment parameters should list the authority and scope of influence separately.
Data and Operational Workflow
Inverter and meter reading → data normalization → cache → 4G reporting → site power generation statistics and operation and maintenance alarms.
The device side, communication side and platform side retain necessary status and logs respectively. Project integration testing is checked with actual equipment data and execution results, and network connection status and business completion status are recorded separately.
Project Inputs
- Existing device models, interface and wiring diagrams, licensing agreements, data samples and available codes.
- Business process and parameters: inverter model, power generation rate, fault code and multi-device polling.
- Target location, operator, SIM/APN, power supply, installation method and equipment size.
- Existing platform interfaces, user roles, development modules, number of prototypes and planned nodes.
Deliverables and Acceptance
| Deliverables | Delivery content | Verification method |
|---|---|---|
| product realization | Hardware design data, prototypes or existing equipment modification data involved in the project, as well as corresponding firmware and interfaces | Check the inverter power, charge and fault fields. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Test multi-device collection timeout and reconnection. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Verify cross-day statistics, make up for network outages, and replace equipment. |
First confirm the scope and key functions, then complete prototype or software development, system integration testing and stage acceptance. The acceptance conditions list the prototype, version, environment, duration and passing threshold; source code, design documents, third-party licenses, materials, traffic, cloud resources and on-site work are agreed separately.
Frequently Asked Questions
Can it be connected to inverters of multiple brands?+
It is necessary to obtain the protocol and test equipment according to the model, and establish field and fault code mapping respectively. Even if the interfaces are the same, the address definition, magnification and write permissions may be different, requiring integration testing on a model-by-model basis.
Can I entrust only part of the functions of the photovoltaic data collection gateway?+
The device interface, terminal program, 4G communication and platform integration testing can be split based on the existing R&D foundation. Please provide existing information and target boundaries, first check the "inverter model, power generation rate, fault code and multi-device polling", and then clarify the deliverables and interface responsibilities of each module.
How are costs and cycle time assessed?+
Split the workload based on target devices, interfaces, existing data, and verification criteria. This project focuses on checking the inverter model, power generation rate, fault code and multi-device polling; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
