FOR EPC CONTRACTORS

Independent fault attribution for warranty disputes.

Performance drops. The OEM blames installation. You blame the cells. The integrator blames both. SynthGrid provides the neutral, physics-based evidence that ends the finger-pointing.

THE PROBLEM

Three parties. Three stories. No neutral data.

When a BESS underperforms, the blame game begins. Each party points at the other two. Without independent data, disputes drag for 12-18 months and cost $300-800K in total resolution costs.

PARTY 1

EPC Contractor

"Installation was to spec." But was the racking thermal design adequate? Were cable runs within voltage drop tolerances? Did commissioning procedures follow manufacturer guidelines? Without independent metering data, you're defending with your own records.

PARTY 2

Cell/Hardware OEM

"Cells meet datasheet specs." But ACCURE found 17% of BESS hardware failed to meet nameplate capacity at SAT. OEMs control the testing environment. Their data is not neutral. Field performance diverges from lab conditions.

PARTY 3

System Integrator

"BMS software is functioning correctly." But was the state-of-charge algorithm calibrated properly? Are thermal management setpoints causing premature derating? Software issues look identical to hardware degradation without physics-level analysis.

Every party has data that supports their position. None of it is independent.

WHAT YOU GET

Neutral evidence. Not another opinion.

SynthGrid cross-references grid meter data against BMS data through a 10-check physics validation pipeline. Phase 2 incorporates rated inverter efficiency curves to isolate battery vs inverter vs BOS losses.

Fault Attribution Report

Physics-based isolation of where losses originate. Battery cells, inverter conversion, balance-of-system wiring, or BMS software derating. Each finding is backed by metered data, not modeling assumptions.

Chain-of-Custody Documentation

Every data point traced from source meter to final report. Documented ingestion timestamps, processing steps, and transformation logic. Full audit trail for opposing counsel review.

Published Methodology

Not a proprietary black box. The 10-check validation pipeline is documented and reproducible. Methodology disclosure package available for opposing counsel. Designed to withstand cross-examination.

Cryptographically Signed Records

Every attestation record is signed with Ed25519 cryptographic keys. Tamper-evident by design. Neither you, your opponent, nor SynthGrid can alter a record after the fact. Verifiable by any third party.

THE PROACTIVE PLAY

Don't wait for the dispute. Prevent it.

EPC firms don't just want dispute evidence. They want dispute prevention. Monitoring from commissioning creates a continuous evidence record that makes finger-pointing impossible.

FROM DAY ONE

Start BatteryPassport monitoring at commissioning. If performance degrades at month 14, you have 14 months of independently verified baseline data showing the system was installed correctly.

The OEM can't claim installation caused the problem when third-party data shows the asset met spec for over a year post-commissioning.

Continuous monitoring also catches issues early - before they become warranty claims. Identify thermal management problems, capacity fade anomalies, or BMS calibration drift in real time.

ECONOMICS: PREVENTION VS CURE

Reactive dispute engagement $50-100K

One-time arbitration scope Single event

Proactive certification $15-30K/yr

Continuous evidence record Ongoing

One dispute avoided pays for 3-5 years of continuous monitoring. Your warranty exposure drops. Your legal costs drop. Your reputation is backed by data, not depositions.

ADMISSIBILITY

Built for adversarial proceedings.

Evidence that can't survive cross-examination is worthless. Every element of the BatteryPassport pipeline is designed to hold up when challenged.

✓

Published methodology. Not a proprietary black box. The validation pipeline is documented, peer-reviewable, and reproducible by any qualified expert.

✓

Documented data pipeline. Every transformation from raw meter data to final report is logged. Opposing counsel can trace any finding back to its source measurement.

✓

Cryptographic signing (Ed25519). Tamper-evident attestation records. Mathematical proof that data has not been altered after creation. Verifiable by any party with the public key.

✓

Methodology disclosure package. Pre-prepared documentation for opposing counsel review. Eliminates discovery delays. Demonstrates transparency and confidence in findings.

✓

Chain-of-custody documentation. Data provenance from meter to report. Ingestion timestamps, processing logs, version-controlled analysis code.

✓

Expert witness availability. SynthGrid engineers are available to present and defend findings in arbitration, mediation, or litigation proceedings.
