A parallel battery installation requires a supported architecture for both the power network and the data network. Addresses, cable assignments and the maximum supported arrangement are product-specific. This guide provides a design review, not a universal wiring or DIP-switch recipe.
Obtain the complete integration package. Use the checklist and scenario below to turn the topic into a documented decision.
Obtain the complete integration package
Identify every BMS, the system controller or inverter, supported firmware and the required communication links. Confirm which ports serve pack networking and which serve the inverter. Similar connectors are not evidence that ports can be exchanged.
A practical review checklist
| Review area | Question to resolve | Evidence to retain |
|---|---|---|
| Power diagram | Branches, protection and isolation | Reviewed system drawing |
| Network diagram | Endpoint roles and permitted topology | Exact product instructions |
| Addressing | Device identity and configuration | Version-matched setup guide |
| Aggregation | Reported measurements and limits | Supported controller behaviour |
| Commissioning | Normal, fault and recovery cases | Approved system test plan |
How to use the checklist
Record the requirement, the document or test supporting it, and any unresolved point. A catalogue description is a useful starting point; it should not be recorded as a completed application test. Keep the evidence tied to the actual product revision and operating conditions.
From the requirement to a decision
A scenario worth reviewing
A cable from another installation is proposed
Check its electrical assignment and purpose against both endpoints before use. Do not infer suitability from connector shape or an online wiring example. Resolve any conflicting documentation with the responsible suppliers.
Prepare the right information for technical review
Bring the relevant model identifiers, revision information, application requirements and existing records to the discussion. Identify the specific question that remains open instead of asking for a recommendation based on a product name alone. For a JK BMS enquiry, request the applicable documentation and written confirmation for the proposed configuration before making a purchasing or installation decision.
This article provides general planning guidance. It does not replace the exact cell, battery, BMS or equipment documentation. Installation, live-battery testing and safety-related configuration changes require qualified personnel and an approved procedure. No product-specific rating, compatibility or certification is established by the conceptual illustration.
