Renogy 320W 12V Monocrystalline Solar Panel 2 Pack
Renogy 320W Solar Panel 2 Pack
The Renogy 320W 12V Monocrystalline Solar Panel 2 Pack includes two 320W monocrystalline modules for a combined 640W STC nameplate array. Each panel uses 60 cells and delivers 33.0V at its optimum operating point, with a 40.3V ± 5% open-circuit voltage and 9.70A optimum operating current. This two-panel configuration is intended for planning a solar array around the connected charge controller and battery system.
Plan the Array and Controller Connection
Before connecting the pair, size the solar charge controller for the array's voltage and current limits. Wiring in series raises array voltage while wiring in parallel raises array current, so compare the chosen configuration with the controller's maximum PV voltage, current, operating range, and applicable oversizing rules. Each module is rated at 320W at STC, with a 20A maximum series fuse rating and 1500VDC maximum system voltage.
Check Space and Mounting Requirements
Allow for two complete panel footprints when planning a roof, ground, or other mounting location. Each module measures 65.6 × 39.4 × 1.4 inches and weighs 39.7 pounds. The panels have tempered 3.2mm front glass and an anodized aluminum alloy frame; confirm the mounting surface, attachment points, service clearance, cable path, and shading conditions before installation.
Outdoor Electrical Details
The panels use solar connectors with 12 AWG, 900mm output cables. The connector assemblies are rated IP67, while the junction box is rated IP68. The documented operating temperature range for each module is -40°C to 85°C, supporting planning for installations exposed to changing outdoor conditions while the array, wiring, protection, and controller are selected as a complete system.
