Enersol Solar Panel Installation Manual

The Enersol Solar Panel System is a high-efficiency photovoltaic solution designed for residential and commercial use, featuring monocrystalline silicon cells, weather-resistant aluminum frames, tempered glass protection, and integrated junction boxes. The system includes mounting hardware, DC connectors, and supports grid-tied or off-grid configurations with compatible inverters. Below are key sections for safety, components, installation, electrical connection, commissioning, maintenance, and troubleshooting.

System Overview & Components

Key components: Enersol Monocrystalline Solar Panels, Mounting Rails & Brackets, DC Connectors (MC4), Junction Boxes, Grounding Hardware, and Installation Manual.

Safety Precautions

Installation involves electrical and height hazards. Follow all safety codes.

1. Electrical Safety: Panels generate DC voltage when exposed to light. Cover panels with opaque material during wiring.
2. Fall Protection: Use harnesses, guardrails when working on roofs.
3. Tool Safety: Use insulated tools for electrical work.
4. Weather: Do not install during rain, snow, or high winds.

WARNING! DC voltage can cause severe shock or arc flash. De-energize system before working. Only qualified personnel should perform installation.

Pre-Installation Planning

Assess site and prepare before installation.

1. Site Survey: Verify roof integrity, orientation (south-facing optimal), shading analysis.
2. Permits & Codes: Obtain local building/electrical permits. Follow NEC Article 690, local codes.
3. Layout Design: Plan array layout for optimal spacing, ventilation, and service access.
4. Material Check: Verify all components are present and undamaged.

CAUTION! Ensure roof structure can support panel weight plus wind/snow loads. Consult structural engineer if unsure.

Mounting & Mechanical Installation

Secure mounting system to roof or ground structure.

1. Install Mounting Rails: Attach L-feet to roof rafters using lag bolts. Secure rails to L-feets.
2. Attach Panels: Place panels on rails, secure with mid-clamps and end-clamps. Maintain minimum gap per manual.
3. Grounding: Connect grounding lug from each panel to rail, and to system ground per NEC.
4. Weather Sealing: Apply sealant around roof penetrations as required.

Tip: Do not overtighten clamps to avoid glass stress. Follow torque specifications.

Electrical Wiring & Connection

Wire panels in series or parallel to match inverter input requirements.

1. String Wiring: Connect panel MC4 connectors in series (positive to negative) to build voltage.
2. Combiner Box: Run home runs to DC combiner box if multiple strings.
3. DC Disconnect: Install fused DC disconnect between array and inverter.
4. Inverter Connection: Connect DC wires to inverter input terminals. Observe polarity.
5. AC Connection: Qualified electrician to connect inverter AC output to building distribution panel.

WARNING! Ensure all DC connections are tight and weatherproof. Use only UV-resistant PV wire.

System Commissioning

Final checks before energizing system.

1. Visual Inspection: Verify all mechanical fasteners, electrical connections, grounding.
2. Continuity & Insulation Tests: Use multimeter to check for shorts, opens, and insulation resistance.
3. Polarity Check: Confirm positive/negative at inverter input matches array.
4. Energize: Remove panel covers, close DC disconnect, then AC disconnect. Monitor inverter startup.
5. Performance Verification: Check inverter display for power output, no error codes.

CAUTION! Do not commission if any damage is found. Contact technical support.

Operation & Monitoring

System operates automatically when sun is present.

• Inverter Display: Shows power (kW), daily energy (kWh), voltage, current.
• Monitoring App: Connect inverter to Wi-Fi/Ethernet for remote monitoring via Enersol portal.
• Normal Operation: No routine intervention needed. System shuts down at night, restarts at dawn.

Tip: Check monitoring app periodically to ensure system is producing expected energy.

Maintenance Guidelines

Minimal maintenance required.

1. Panel Cleaning: Clean glass surface with water and soft cloth if soiled (e.g., pollen, dust). Do not use abrasive materials.
2. Visual Inspections: Periodically check for physical damage, loose connections, vegetation shading.
3. Electrical Inspection: Annual check by qualified technician of connections, insulation, grounding.

CAUTION! Do not walk on panels. Do not clean with harsh chemicals or pressure washers.
