4mm² PV Solar Cable with MC4 (20m)
A 20-metre 4mm² tinned-copper PV cable rated 1500V DC with double insulation and IP67 MC4-compatible connectors pre-fitted on both ends for plug-and-play solar wiring.
Balance-of-system that lasts
Mounting, wiring and protection are the balance-of-system parts that make a solar array safe and long-lived. Anodised aluminium rails and stainless fasteners hold panels through wind and snow, PV cable and MC4 connectors carry DC power safely, and a distribution box with breakers isolates and protects each circuit.
These components meet standard PV ratings for voltage, current and outdoor exposure, and pair directly with our panels and inverters. OCALWA supplies complete balance-of-system so a project ships as one matched order.

Configurations & options
Voltage, power rating, battery capacity and configuration are matched to your project, grid and climate. Send us your load, backup and site details and we will size the right system.
Why choose matched balance-of-system
Safe and code-ready
Correctly rated cable, connectors and breakers keep the DC system safe and easier to certify.
Built for the outdoors
Anodised aluminium, stainless steel and UV-resistant cable survive decades of sun, salt and rain.
One matched order
Rails, cable and protection ship with the panels and inverter so nothing is missing on site.

Frequently asked questions
The mounting clamps adjust to standard module thicknesses and the hooks suit tile, metal and pitched roofs; tell us your panel size and roof type and we will confirm the right kit.
PV cable is 4mm² (6mm² available) rated 1500V DC with IP67 MC4 connectors; the distribution box carries three DIN-rail breakers, typically 16-63A, with an optional surge protection device.
Yes. Besides pitched and metal roof kits we supply ground-mount and carport structures; tell us the roof or ground type and array size and we specify the right system.
Anodised aluminium rails and stainless fasteners typically carry a 10-15 year structural warranty and last 25+ years outdoors; PV cable is rated for a 25-year service life.
Yes. We consolidate matched inverters, batteries, panels and balance-of-system from one verified factory into full containers, with export documentation, certification and quality control managed by OCALWA.
