LONGi LR7-54HVH-490M Hi-MO X10 Explorer 490W Solar Panel

This module is based on advanced monocrystalline cell technology, engineered to provide high efficiency, improved energy yield, and strong performance under real-world conditions such as low irradiance and higher operating temperatures.

The LONGi 490W N-type rooftop module is frequently specified for high-density residential and light commercial PV systems where string voltage planning, inverter compatibility, and pallet optimization matter. With its high power class, this 490W panel allows installers to reach 10 kW+ system targets with fewer modules compared to 430–460W alternatives, reducing mounting rails, clamps, DC connectors, and overall BOS complexity.

LONGi 490W String Design Considerations

For modern European string design, the 490W configuration supports efficient layout planning in 1000V systems. Installers typically evaluate:

• Voc at low-temperature conditions

• String length limits for 3-phase inverters

• MPPT operating window alignment

• Current matching across parallel strings

The module’s electrical characteristics enable flexible string sizing for common 8–15 kW and 15–30 kW rooftop inverter setups.

490W Module for 3-Phase Inverter Systems

The LONGi 490W N-type panel integrates cleanly with most 3-phase string and hybrid inverter platforms deployed in residential and C&I projects. Its voltage and current profile allows practical string grouping without overloading MPPT channels, making it suitable for balanced three-phase grid-connected systems.

LONGi 490W for 10kW System Planning

In a typical 10 kW rooftop system, installers can achieve target capacity with fewer high-power modules compared to mid-range wattage panels. This reduces:

• Roof penetration points

• Cable runs

• Installation time

• Structural load distribution complexity

For commercial rooftops, scaling to 20–30 kW becomes more straightforward when using higher wattage modules like the LONGi 490W.

54-Cell High-Voltage LONGi Configuration

The 54-cell high-voltage architecture is optimized for compact rooftop layouts and modern inverter voltage ranges. This format is particularly relevant for residential and small commercial installations requiring high output within limited surface area.

LONGi 490W Voc & Current Compatibility

During system design, installers should verify:

• Open-circuit voltage (Voc) at minimum site temperature

• Maximum system voltage limits

• String current alignment with inverter MPPT input ratings

The 490W N-type configuration is engineered to maintain predictable electrical behavior across temperature variations, supporting stable annual yield calculations.

490W Panel for Hybrid Inverter Integration

This module is frequently used in hybrid-ready PV systems where solar panels are paired with battery storage. Proper string sizing ensures compatibility with hybrid inverter MPPT ranges while maintaining optimal DC-to-AC ratios in energy storage applications.

LONGi 490W Pallet Quantity & Procurement Efficiency

For solar wholesalers and EPC procurement teams, 490W modules offer practical pallet logistics and improved Wp-per-pallet density. Higher wattage per unit supports more efficient warehouse rotation and transport optimization compared to lower wattage alternatives.
