The Solwel 4.4kW NanoRack Roof Mount Solar Kit is a complete, installer-ready solar package combining 10 Hanersun 440W monocrystalline panels, the NanoRack rail-free mounting system, and 5 APsystems DS3 880VAC dual-input microinverters with monitoring gateway. Everything needed for a 10-panel, 4.4kW rooftop array - panels, racking, inverters, trunk cables, and monitoring - in one order.
The array is designed in a 2P � 2C layout (2 panels per column, 2 columns per inverter) with each DS3 microinverter handling 2 panels, delivering true module-level power electronics across the entire array.

Key Features
- Module-level performance: Each panel is independently optimized and monitored - shading on one panel does not impact the rest of the array
- Rail-free NanoRack mounting: Faster installation than traditional rail systems; designed for standard asphalt shingle and comp roofs
- Built-in monitoring: APsystems ECU-R gateway provides real-time per-panel production data via the EMA app
- Plug-and-play AC trunk wiring: DS3 trunk cables daisy-chain all inverters for a clean, simplified AC run to the breaker panel
- Utility-interactive: Grid-tied microinverter system; no battery required
Frequently Asked Questions
Is battery storage included?
No - this is a grid-tied solar-only kit. It is designed to offset your utility bill by exporting power during the day. Battery storage can be added separately.
What roof types is the NanoRack system compatible with?
NanoRack is designed for standard composition shingle (asphalt) roofs. Confirm compatibility with your installer for tile, metal, or flat roofs.
Do I need an electrician or solar installer?
Yes. This kit requires professional installation and must be permitted through your local AHJ (Authority Having Jurisdiction). The inverters must be interconnected to the utility grid per NEC requirements.
What monitoring does this system include?
The APsystems ECU-R gateway connects to your home Wi-Fi and provides module-level production data through the APsystems EMA monitoring platform (free app and web portal).
Is this eligible for the federal solar tax credit (ITC)?
Complete solar systems (panels + inverters + racking) installed on a primary or secondary residence generally qualify for the federal residential clean energy credit. Consult your tax advisor to confirm eligibility for your specific situation.
