String-level visibility, zero blind spots.

DYNVOLT is solar SCADA software that polls every inverter, every string, every meter — every 30 seconds — over Modbus TCP. Detect underperformance, ground faults, and degradation before they cost you yield.

REAL-TIME TELEMETRY

Every inverter. Every string. Every 30 seconds.

DYNVOLT speaks Modbus TCP natively. Edge node polls every device on a deterministic schedule, normalizes the readings into a single time-series schema, and pushes to your control room and the cloud simultaneously.

●
Per-string DC current and voltage — spot a degraded panel before it pulls down a whole combiner.
●
Per-inverter AC power, frequency, PF — match grid-operator requirements for reactive support.
●
Weather and irradiance — POA, GTI, ambient T, cell T, wind speed at 30s.

DYNVOLT SCADA — string-level inverter monitoring with 30-second telemetry

CAPABILITIES

Solar SCADA software built for utility-scale plants.

⌬

Hot-swap inverters without losing context.

Replacing an inverter? DYNVOLT continues the asset's history under the same logical ID. No data gaps, no lost trends.

⎈

Grid control & curtailment.

The export limit configured at the point of connection is enforced from the edge; curtailment is applied on instruction received through your existing operator channel. Set-point write-back and ramp-rate limiting — every command RBAC-gated and audit-logged, no cloud round-trip.

Fault detection in < 30s.

Pattern-match string current vs. siblings to flag PID, soiling, and bypass-diode failures.

Severity-scored alerts.

Critical / High / Medium / Low classified automatically. Routed to your O&M ticket system.

⊞

Logical site mapping.

Group strings into combiners, combiners into trackers, trackers into blocks. Aggregate any way.

Expected-versus-measured current, every 30 seconds. I-V sweeps on schedule.

Two mechanisms, clearly separated. Continuously: every string's measured current is benchmarked against model-expected current under live irradiance and cell temperature, flagging soiling and degradation long before a monthly report would. Periodically: inverter-initiated I-V sweeps capture the full curve for deeper diagnosis.

How fast does DYNVOLT poll inverters?

Edge nodes poll over Modbus TCP every 30 seconds, with poll latency to the cabinet under 50ms.

Which inverter brands are supported?

Validated in production: the Huawei SmartLogger 3000 and SUN2000 families — per-inverter and per-string registers, both addressing modes, across two plant generations. Beyond that we integrate at the protocol level: any device with a documented Modbus TCP map can be added, and we scope the effort for your hardware before you commit.

Does it work without internet?

Yes. The edge node has a 14-day local buffer and runs control logic, alarms, and interlocks autonomously. When the link returns, history is replayed gap-free.

Can it write set-points back to inverters?

Yes — power limits, curtailment, and reactive support are pushed back via the same Modbus session. Write-back is gated by RBAC and audit-logged. The export limit configured at the point of connection is enforced from the edge.

What about string-level visibility?

Per-string DC current, voltage, and energy are normalized into the same time-series schema as plant aggregates. Every 30 seconds, measured string current is benchmarked against its same-orientation peers; sustained underperformance opens a ticket after multi-day persistence checks.
