TUV-certified MC4 connectors, solar cable assemblies, and junction box connectors for rooftop, utility-scale, and off-grid photovoltaic installations.
Copper and laminated busbars for battery energy storage systems (BESS), connecting battery modules, inverters, and power conversion systems.
High-current power connectors and slip ring assemblies for wind turbine generators, pitch systems, and nacelle-to-tower cabling.
AC/DC busbars, terminal blocks, and power connectors for string inverters, central inverters, and microinverters.
Connectors and cable assemblies for solar-powered EV charging stations, combining renewable generation with electric vehicle charging.
PV / ESS System Fit
The resource pack connects solar and storage as one sourcing problem: PV junction boxes and DC connectors at the module/string layer, busbars and high-voltage connectors at the power layer, then waterproof RJ45/USB and BMS collection connectors at the signal layer.
PV junction box, diode set, panel lead, PV DC connector
Resource-pack specifications include 1500V DC junction box families, IP68 sealing, Class II / Class A references, and 25A-35A current bands.
1500V DC connectors, branch leads, extension cable assemblies
DC connector families cover 36A, 41A, 50A, 60A, and 80A options with PV cable sizes from 2.5mm² to 16mm².
Busbar, terminal block, DC connector, waterproof circular connector
Use this layer to align current rating, IP rating, contact resistance, impulse withstand, and enclosure routing.
Laminated busbar, ESS DC connector, single-core high-current connector
ESS connector families include 1000V 90A/120A single-core options and 1500V DC 60A/80A connector options.
Waterproof RJ45, waterproof USB2.0-A, BMS low-voltage collection connector
PCS and BMS interfaces need different connector logic than high-current power paths, especially for outdoor cabinets.

Request Drawing Workflow
The Solar / PV page now exposes old-site product records with local imagery and extracted specifications, then routes missing datasheets through Request Drawing instead of leaving buyers at a dead end.
Request Renewable DrawingChoose PV connector, junction box, ESS busbar, or signal interface from the product page.
Open the matching detail page and use Request Drawing when the PDF is not yet published.
Send cable size, voltage/current class, mating interface, sealing target, and sample schedule with the RFQ.
CZT sales confirms the latest drawing revision before sample, tooling, or volume quotation.
RFQ Inputs
The fastest RFQ path is to specify the system layer first: module junction box, PV string connector, inverter interface, battery power path, PCS communication, or BMS collection. Current, voltage, IP rating, cable size, and mating interface can then be narrowed without mixing unrelated connector types.
