Define the project and the next decision.
Review your application, market, current supplier, timeline and available documents. Identify what is known and what still needs verification.
HOW WE WORKOne quality baseline.
One quality baseline.
From first brief to release.
Procurement decisions become easier to explain when requirements, checks and records stay connected.
Start with the decision.
Work back to the evidence.
You don’t need to begin with every document ready. Start with the project stage, the supplier situation and what you need to decide next.
Set a clear scope before work begins.
Agree the stage, inputs, deliverables, factory access, schedule, fees and boundaries. Specify how additional work and unexpected findings will be handled.
Check the evidence against the baseline.
Review source documents and carry out the agreed factory or test work. Record the condition observed, its reference and the scope affected.
Follow issues to a reasoned conclusion.
Connect supplier actions with retest and closure evidence. Explain remaining risks and the recommendation. You retain the project decision.
INSPECTION & TEST PLANKnow when to stop.
Know when to stop.
What to witness.
Which records to review.
The project ITP defines each control point, acceptance criteria, responsibilities and required records. Agree it before production so inspection has a clear basis.
H / Hold
The named gate requires accepted evidence and release by the authorised party before the next step, as agreed in the project plan.
W / Witness
Attend the specified process or test after agreed notice. Record conditions and results, and apply the project’s absence rules.
R / Review
Examine source records, coverage, unit identifiers and test conditions. A document review does not replace a separate hold-point release.
PRACTICAL QUESTIONS
Before we start.
Can I start if I already have a supplier?
Yes. The nominated-supplier route combines remote review with factory verification. If production or FAT is already approaching, the first step is to establish which requirements, access rights and acceptance criteria are already agreed.
Do I have to buy the complete P1–P7 service?
Scope is based on your current project and available evidence. Stages can be commissioned separately where their inputs are ready. Production and FAT support need an agreed technical and quality baseline; P5 establishes that baseline for execution.
Do you sell equipment or receive supplier commissions?
No. The service is paid for by the buyer under the agreed scope. TX Inverter does not resell BESS equipment, earn a product trading margin or collect supplier fees, commissions or rebates.
What happens if the factory needs more time?
The proposal specifies included site days, visits and review work. If more work is needed, scope and fees are agreed in writing before it continues. There is no unlimited on-site commitment hidden inside a fixed fee.
Does a factory audit or FAT guarantee the equipment?
Findings and recommendations cover the evidence, sampling and activities agreed for the project. They are not product certification or an unlimited equipment-performance guarantee. The supplier remains responsible for its product and contractual commitments.
What is useful for the first conversation?
Your company and project market, application, approximate power and capacity if known, current procurement stage, supplier situation, expected timeline and the main decision or concern. You can describe the situation before sharing confidential project documents.
