LETOP fulfills the growing demand for solar combiner box solutions by making reliable and cost-effective combiner boxes for commercial and industrial PV systems. These boxes can improve the operational efficiency of your system and simplify the installation process. LETOP’s products provide electrical circuit protection and protect the systems from overcurrent, overvoltage and other hazards that might occur.
A standard 5kW solar system can have around 12-15 solar panels that make approximately 5,000 – 6,000 kWh of energy annually and cover roughly 30-35 square meters of space. This system is good for small households with basic electricity needs.
Combiner box is compact and wall-mountable with simple installation.
20KW LETOP combiner boxes are suitable for systems that operate at 1000V DC.
A 100kW system can have between 250 & 300 solar panels and have an energy output of almost 130,000–145,000 kWh annually. This solar system can take up a space of around 600 square meters. This configuration is used for large offices, medium-scale factories and warehouses.
These combiner boxes have multi-string connectivity and a built-in monitoring option.
LETOP combiner boxes are suitable for applications that work in 1500V DC.
A 500kW system has around 1,200 – 1,500 panels that can generate around 650,000–720,000 kWh of electricity annually. These plates occupy a space of approximately 3,000 square meters. These configurations are used in large factories, manufacturing facilities or distribution centers.
They can also handle high currents and are equipped with advanced protection.
Combiner box works well with a 1500V DC solar system.
explore moreComplex System Design & Integration
Challenge: Solar system installations can face compatibility issues, complex wiring and an extended installation timeline. This poor integration can make your system not work well which can result in energy loss.
LETOP’s Solution: LETOP can help you with these problems with simple design and standardized interfaces that are compatible with most brands. We can also help you with CAD support for your custom system design.
Explore MoreHigh Operation & Maintenance Costs
Challenge: In large scale systems, failure of any component can result in downtime which can be very costly. This can also cost a lot by stopping your operations and additional maintenance costs.
LETOP’s Solution: LETOP can help you with this problem by providing integrated components and monitoring systems with easy-to-understand fault diagnostics. Its front-maintenance structure will help you keep the upkeep of the system simple and smooth.
Ensuring System Reliability & Safety
Challenge: With poor management or poor connection in your combiner box, the operators will always be at high risk of shocks. Your system will also be prone to risks like overcurrent, short circuits and lightning strikes.
LETOP’s Solution: LETOP combiner boxes have 1000V/1500V systems with IP65 protection ratings, Type 2 lightning care and low failure risks. These protections will make sure your system always runs smoothly and give you reliable operation.
Meeting Project Deadlines & Managing Supply Chain
Challenge: Large PV systems need a bigger combiner box and a large number of components. It can also take a long time for deliveries and to get everything ready quickly for your system. Delayed deliveries and inconsistency in inventory can delay your project from the expected schedule.
LETOP’s Solution: LETOP always has regular stock availability and has a 72-hour dispatch policy for all its core products. With a consistent inventory, we make sure that you can carry on your project smoothly and finish it within the expected timelines.
Explore MoreCost Optimization in Large-Scale Deployments
Challenge: Managing labor and materials while keeping expenses low can become overwhelming sometimes.
LETOP’s Solution: LETOP controls its industrial hub location, standardized designs and scalable production. This makes sure the cost remains under control without sacrificing the quality of the combiner box or the components.
