OnGrid Inverter

Technical Specifications & Product Selection Guide

Industrial grid-tied systems demand exact alignment between input photovoltaic string architectures and utility voltage baselines. The table below lists the technical reference specifications for our factory standard(three-phase) high-voltage on-grid platforms, compiled to assist procurement managers during project component matching.

Engineering Customization Services Available for Global Projects

Standard power electronics frequently require physical and programmatic modifications to maintain operational baseline integrity across non-standard distribution networks. Our China factory provides advanced engineering support tailored for large-scale procurement.

Grid Code Compliance & Firmware Flashing: Our automated programming lines pre-configure localized utility interface protocols. Customization services available include direct adaptation for European EN 50549-1, German VDE-AR-N 4105, British G99, and American IEEE 1547 standards to eliminate legal integration bottlenecks.

Hardware & Communication Protocol Mapping: We support communication interface adjustments. Our engineering team can rewrite communication firmware to map inverter internal metrics directly to customized Modbus, RS485, CANbus, or GPRS telemetry setups utilized by proprietary third-party SCADA platforms.

Manufacturing Strengths, Production Capacity & QC Infrastructure

Xiamen Hemao Industry operates a production infrastructure engineered to manage high-volume supply contracts without deviating from zero-defect manufacturing thresholds.

Verified Plant Throughput: Our China manufacturing plant features fully automated surface mount technology (SMT) component placement systems and robotic structural soldering bays, generating a reliable monthly output exceeding 20,000 grid-tied power modules.

Component-Level Verification & Burn-In Matrix: We execute a 100% full-load high-temperature burn-in sequence inside closed thermal chambers. Every unit operates at maximum rated current capacity under 50°C temperatures for 4 hours to verify IGBT thermal dissipation boundaries.

Global Quality Auditing: Our entire factory operation is audited under ISO9001:2015 quality control and ISO14001:2015 environmental safety parameters. Final products are dispatched with verifiable CE, TUV, IEC 62109-1/-2, and RoHS compliance certifications.

FAQ

Q: How do your customization services handle requests for zero-export configurations in commercial zones with strict grid-injection laws?

A: We provide custom control loop firmwares that interface directly with external smart meters or current transformers (CT). The internal processing unit updates its output throttle every 50 milliseconds, limiting reverse power injection to ≤0.5% of rated capacity.

Q: What specific hardware customization services are available for coastal or high-humidity tropical installation environments?

A: For high-corrosion zones, we substitute our standard casing materials with premium C5-high anti-corrosion rated die-cast aluminum enclosures. All internal mainboards receive a double-layer automated conformal coating spray to insulate sensitive power traces from salt mist and ambient humidity.

Q: What is the factory processing time for a custom batch of 50 units with proprietary RAL enclosure paint codes?

A: Once the specific RAL color code selection is formally logged and approved by our production desk, the custom sheet metal coating process adds exactly 5 working days to our standard assembly timeline, resulting in a total delivery window of 20 to 25 working days.
