Ensure maximum survivability and performance for your offshore solar assets with LETOP combiner boxes built for extreme corrosion, water ingress, and mechanical stress.
Offshore solar installations are the new frontier of PV deployment, facing environmental challenges that go beyond those on land or near-shore. The components are constantly exposed to corrosive salt spray and fog, extreme humidity, potential direct wave impact, significant structural vibration, high wind loads, and intense UV radiation. The remote location makes maintenance exceptionally difficult and costly.
The standard electrical enclosures just aren’t good enough for these conditions, leading to rapid degradation, failure, safety risks, and significant financial losses.
LETOP provides heavy-duty solar combiner boxes specifically designed for offshore survival. Our design philosophy prioritizes maximum corrosion resistance using premium marine-grade materials (316L Stainless Steel or higher), achieves superior watertight integrity (IP67/IP68), ensures extreme mechanical robustness, and delivers the uncompromising long-term reliability demanded by offshore assets.
We mainly use superior alloys (316L Stainless Steel) for enclosures, fixings, and external components. If you want even more protection, you can get specialized marine-grade coatings. Whenever possible, use highly resistant internal components made of non-metallic materials.
Designed and tested to IP67 (immersion resistant) or IP68 (continuous immersion) standards. Employs high-performance, chemically resistant gaskets (silicone, EPDM) and sturdy, multi-stage sealing mechanisms for cable entries (premium IP68 glands).
Building the IK10 Heavy-gauge enclosure. Reinforced mounting points. The internal components are braced and vented to withstand constant structural vibrations and potential shock loads from wave action or operational activities.
We've selected every component for maximum durability in the marine environment to extend service life significantly and minimize expensive offshore interventions.
High-integrity IP67/IP68 rated breather vents are standard, crucial for managing internal pressure changes and preventing condensation buildup in high-humidity environments without compromising the seal.
We understand that every solar project is unique. Find the perfect LETOP combiner box solution organized by what matters most to you.
