Q1: How to quickly determine if a DC Combiner Box suits my application?
Evaluate three key factors: system voltage compatibility (1000V vs 1500V), required input channels (based on string configuration), and environmental conditions (IP rating requirements). Match these with your solar array specifications for optimal selection.
Q2: What are the 3 most important parameters when selecting a DC Combiner Box?
1) Maximum DC voltage rating (must exceed system voltage by 25%), 2) Current capacity per input (match string current with safety margin), 3) Environmental protection rating (IP65 minimum for outdoor installations).
Q3: How do material and process choices affect performance and cost?
Aluminum enclosures offer better heat dissipation but cost 15-20% more than steel. Stainless steel hardware adds 10% cost but ensures 25-year durability. UV-resistant materials are essential for outdoor applications despite 5-8% cost premium.
Q4: How to create an effective custom design specification?
Provide complete electrical specifications, environmental requirements, physical constraints, regulatory compliance needs, and quantity projections. Include application drawings and existing product references to ensure accurate customization.
