Complete Solar PV BOM — Every Component, One Supplier
A photovoltaic system is a chain of interconnected components. This guide walks through each link of the chain — and shows how EnergyLink Parts covers the whole BOM under one roof.
The PV System BOM Chain
PV Module → Junction Box → Connectors → Wiring → Combiner → Inverter → Protection
Solar PV Junction Box
Mounted on each PV module, the junction box integrates bypass diodes that prevent hot-spot damage and ensure safe string operation. Rated up to 1500V DC with UL listing.
MC4 Connector
The industry-standard quick-lock connector linking modules, strings and inverters. High current rating, IP-rated sealing and proven mating cycles for 25+ year system life.
T3 Connector
PV004-T3 T-branch connector rated 1000V DC / 30A, IP65, MC4-compatible. Compact T-branch design for module-to-string wiring in rooftop arrays.
T4 Connector
PV004-T4 4-way branch connector rated 1000-1500V DC / 30-50A, IP68, MC4-compatible. One-to-four branch for string aggregation and combiner input.
PV Combiner Box
Aggregates multiple PV strings into a single output, with fuses, surge protection and optional monitoring. Essential for rooftop and ground-mount arrays to simplify inverter connections.
Hybrid Solar Inverter
Converts DC to grid-ready AC with MPPT tracking, battery charging (up to 120A) and storage integration. 3.6–6.5kW models, parallel up to 9 units, RS485/CAN BMS.
DC Circuit Breaker
Protects DC circuits from overcurrent and short circuits. 500VDC rating with 6kA breaking capacity, compliant with IEC 60898-2 and IEC 60947-2 — trusted by electricians worldwide.
