Testers for O&M teams and EPCs

Choosing a tester does not end with the datasheet. What matters is whether the tester, software, team structure and reporting requirements fit into an effective workflow in the solar park. sunparq classifies measurement solutions by use case, data process and operational usability.

For O&M teams, EPCs and technical leads of utility-scale solar parks
Classification of PV testers up to 1500 V and AC-side measurement technology up to 800 V grid voltage
Focus on measurement practice, software, data management, reporting and team readiness

Evaluate testers in their operational context

1. Clarify the use case Which measurements, plant structures, grid levels and O&M tasks need to be covered?
2. Classify the measurement solution Does the combination of tester, accessories, software and data structure fit the real field process?
3. Prepare the workflow Define training, project structure, measurement procedure, data export and reporting clearly before field use
4. Secure operation Establish support, onboarding, report reviews and process updates for ongoing O&M operation

A tester is good. A measurement solution is better.

The right tester for your teams and processes

In O&M teams, the datasheet alone is not decisive. What matters is whether a tester fits existing workflows, technicians become productive quickly, data is structured cleanly and reports can be created reliably.

Measurement task

Which tests really need to be performed on site?

Team structure

How many technicians work with the device and how quickly do new people need to be onboarded?

Data & reporting

How are measurement data stored, evaluated and transferred into reports?

Support readiness

What happens when unclear measurement results or operating issues occur in the field?

PV measurement technology in the solar park

PV testers up to 1500 V

The following device pages classify PV testers not only by technical specifications, but by their practical use in O&M operation: measurement tasks, software, data structure, reporting, training needs and workflow fit in the solar park.

Grid and loop impedance in large-scale PV plants

Loop impedance testers up to 800 V grid voltage

For service and O&M teams in solar parks, checking AC-side grid and protective measures is relevant alongside DC-side PV measurements. The following testers are designed for loop impedance measurements in grids up to 800 V and complement other testers in the operational inspection process.

Your next step

Device comparison is only the beginning

Depending on your starting point, the next step may be selection guidance, training or a complete rollout.

Do you already have a device?

Then device-specific training can be the fastest entry point to make your team productive.

Do you want to select a tester?

Then we assess requirements, use cases, software needs and reporting in the Measurement Assessment.

Do you want to implement the solution?

Then the Measurement Rollout supports device introduction, training, workflow, data management and reporting.

Next step

In 15 minutes, we clarify whether and how we can help

We first review your target setup, team structure, PV testers, reporting and support needs - then we decide together whether Assessment, Rollout or Operational Readiness is the right fit.
