Solar and PV Monitoring Electronics
PV monitoring electronics operate on high-voltage DC strings and must survive surge events on field-deployed communication ports. Isolation creepage on PCB at 1500 V DC potential is a design constraint that assembly must not compromise. SunSpec and Modbus map compliance determines interoperability with every inverter brand on site.
Buyer pains we hear most
- 1500 V DC isolation creepage distances on PCB are easily compromised by conformal coat bridging or contamination in assembly
- Lightning and switching surge events on communication ports cause field returns that are preventable with correct TVS placement and assembly
- SunSpec and Modbus register map compliance must be verified against multiple inverter brands before shipment
- UV-stable enclosure materials are frequently omitted from the initial BOM and only discovered during field inspection
Typical product traits
- DC string voltage and current sensing with reinforced isolation rated to 1500 V PV potential
- PLC, RS-485, or wireless mesh communication to gateway
- Modbus TCP and SunSpec-compliant gateway output
- Surge protection on all PV-side communication ports

Test plan considerations
- Per-unit hipot test across reinforced isolation barrier at 1500 V DC string potential
- Surge protection component verification per unit on communication ports
- Modbus and SunSpec register map functional test against reference inverter simulator
- Enclosure UV resistance material review at BOM stage before first production build
Frequently asked questions
Do we need a written test plan?
Yes. A production test plan defines pass and fail criteria, FCT vectors, calibration steps, and serialization rules. We help draft one if your team has not written one yet, based on your firmware behavior and target field performance.
Do you support RoHS and REACH compliance?
Yes. We work with RoHS-compliant component selection and SAC305 lead-free solder by default. REACH substance documentation comes from supplier declarations forwarded with each batch.
Do you manage component sourcing?
Yes. We work from your approved vendor list (AVL) or build one with you, including dual-source identification for lead-time risk. We flag obsolete or long-lead parts during DFM review and propose alternates when needed.
