Floating PV (FPV) Solar Combiner Boxes

Secure your energy future with LETOP’s combiner boxes, engineered for critical performance in off-grid and microgrid solar applications.

Engineered for Reliability on Water

Floating Photovoltaic (FPV) systems on bodies of water like reservoirs and lakes, present a unique set of environmental challenges for electrical components. Constant high humidity, potential water spray, and condensation risks demand exceptional sealing. The floating platform needs strong mechanical construction and secure connections to keep it moving and vibrating. Even in freshwater environments, standard materials can be affected by long-term corrosion risks.
Compromises in combiner box integrity in FPV systems can lead to critical failures, safety hazards, and costly maintenance interventions due to difficult access.
LETOP provides solar combiner boxes specifically engineered for the demands of FPV installations. Our solutions focus on superior watertight protection (IP66/IP67), the use of highly corrosion-resistant materials, designs that withstand mechanical stress, and integrated condensation management features.

Engineered for Water: The LETOP FPV Advantage

Superior Water Protection

Superior Water Protection

Achieved through high IP ratings (IP66/IP67), quality gaskets, and IP68 watertight cable glands to prevent water intrusion from humidity, spray, and potential splashing.

Enhanced Corrosion Resistance

Enhanced Corrosion Resistance

Stainless Steel or high-grade GRP/FRP enclosures, along with properly rated internal components and contact accessories, make materials inherently resistant to moisture and corrosion.

Robust Mechanical Stability

Robust Mechanical Stability

Strong enclosure construction and secure internal component mounting designed to withstand the constant motion and vibrations typical of floating platforms. Securing cable management solutions is important.

Superior Water Protection

Effective Condensation Management

Incorporating IP-rated breather drains/vents allows pressure equalization and passive moisture vapor release, significantly reducing internal condensation buildup caused by temperature fluctuations over water.

Enhanced Corrosion Resistance

Long-Term Reliability & Reduced Maintenance

High-quality components, robust design, and superior protection minimize the need for interventions, crucial for less accessible FPV installations.

We understand that every solar project is unique. Find the perfect LETOP combiner box solution organized by what matters most to you.
