Ensure long-term solar performance against biting cold, relentless salt spray, and high humidity with LETOP’s specially designed combiner boxes.
Coastal installations in regions like Northern Europe (e.g., Scotland, Norway) or the North American coastlines (e.g., British Columbia, Nova Scotia) face a unique threat from freezing temperatures, pervasive dampness, and the highly corrosive effects of airborne salt. These conditions can often cause standard equipment to fail prematurely. Corrosion attacks enclosures and terminals, low temperatures can make materials brittle . Moisture ingress can cause short circuits and ice damage.
LETOP provides a strong defense with solar combiner boxes engineered for cold coastal climates. We prioritize superior corrosion-resistant materials, effective sealing (IP65/IP66), and components proven reliable down to low operating temperatures (-25°C or -40°C). Keep your project’s success going with LETOP.
Avoid getting sprayed with aggressive salt spray with premium enclosures like Grade 304 or 316 Stainless Steel. This helps prevent premature rusting and degradation, vital near the sea.
Designed and tested for performance in cold conditions, utilizing materials that resist brittleness and components rated for extended operation down to -25°C or even -40°C.
Achieves IP65 or higher (IP66 recommended) protection, using durable gaskets and secure locking mechanisms to prevent ingress of rain, fog, sea spray, and melting snow/ice.
Incorporates features like breather drains that equalize pressure and allow for controlled moisture egress without compromising the seal against external contaminants like salt.
Built to withstand strong coastal winds and harsh weather, ensuring the physical integrity of the enclosure and secure mounting for the long term.
By resisting corrosion and performing reliably in cold weather, LETOP combiners minimize costly repairs and replacements, improving the project's economics in challenging locations.
We understand that every solar project is unique. Find the perfect LETOP combiner box solution organized by what matters most to you.
