The problem

Most teams trust the report.
They shouldn't.

Five-figure exposure gets missed every month.

Your OEM calculates the number that determines what they owe you.

Availability is often calculated differently than the contract defines

Excused vs. unexcused downtime gets misclassified

Errors aren't caught until month-end, if at all

Who uses it

Built for battery storage owners and operators

For Operations

Stop digging through alarms to find root cause

  • Hundreds of alarms triaged down to what actually matters
  • Root cause tied directly to contract impact
  • Dispute-ready summaries for every major outage
For Asset Management

Know exactly when you're missing guarantees, and why

  • Alerts when availability drops below guarantee
  • Surface warranty claims before they expire
  • Auto-classify excused vs. unexcused downtime

Examples

Real questions, real decisions

"Is this string degraded or was the test bad?"
Test artifact. String performed normally in operations. No warranty claim needed.
"I have hundreds of alarms. What actually matters?"
3 real issues. 197 alarms you can ignore. Here's where to focus.
Proactive Alert
Availability trending below guarantee with 5 days left in the month
$15K exposure. One inverter fault explains the gap. Likely excused. No penalty if documented correctly.
