How to Choose the Right Solar or Battery Cable
Are you extending a solar panel run to a charge controller? Choose a Victron Energy or Volts Energies pre-terminated MC4 solar cable in 6mm2 or AWG10. Select the length that matches your panel-to-controller distance without excess cable.
Are you connecting panels in parallel? Choose Victron Energy MC4 Y-Splitter pairs or Volts Energies MC4 Y-Branch connectors to combine two panel outputs into one cable run.
Are you wiring a Victron MultiPlus or Quattro inverter charger to a battery bank? Choose Volts Energies Heavy Duty Inverter Cables or Elios AWG4/0 inverter cable pairs with pre-installed M8 lugs. Size the cable to match your inverter's rated input current.
Are you connecting multiple batteries in series or parallel? Choose Volts Energies Heavy Duty Battery Interconnect Cables in Gauge 4 AWG. Use equal cable lengths between all batteries to ensure balanced current distribution.
Are you installing an Elios Litio 5.12 LiFePO4 battery? Choose the Elios Litio 5.12 Cable Kit which includes all required positive, negative, communication, and ground cables in matched lengths.
Are you connecting a Victron Smart IP43 or Skylla-S charger to Canadian shore power? Choose the Victron Energy NEMA 6-15P Mains Cord 2m for standard Canadian 240V outlets.

Why Tinned Copper Conductors Matter for Canadian Installations
All Volts Energies and Victron Energy cables use tinned copper conductors. Bare copper oxidizes when exposed to humidity and temperature cycling, increasing resistance and generating heat at connection points over time. Tinned copper resists oxidation throughout the cable and at termination points, maintaining rated conductivity over the full system lifespan.
This is especially important for Canadian coastal and humid environments including BC, Nova Scotia, New Brunswick, and Ontario lakefront properties where moisture exposure is constant.
FAQs
What Is The Difference Between 4mm2 And 6mm2 Solar Cable?
4mm2 solar cable is rated for lower current solar panel runs typically below 25A. 6mm2 cable handles higher current runs up to approximately 40A to 50A and is the standard size for most residential and off-grid solar panel installations. For longer panel runs, 6mm2 minimizes voltage drop.
Can I Use Victron Solar Cables With Non-Victron Solar Panels?
Yes. Victron Energy solar cables use standard MC4 connectors and are compatible with all major solar panel brands, including Canadian Solar, LG Solar, SunPower, and Lumera Solar panels stocked at Volts Energies.
What Size Inverter Cable Do I Need For A Victron MultiPlus 3000VA?
A Victron MultiPlus 3000VA at 12V draws approximately 250A at full load. Victron recommends a minimum 70mm2 cable for runs up to 1m and larger for longer runs. The Elios AWG4/0 inverter cable pair (approximately 120mm2) is the correct choice for most MultiPlus 3000VA installations.
Are The HYXI Trunk Cables Compatible With Non-HYXI Microinverters?
HYXI trunk cables are designed specifically for HYXI microinverter AC bus systems. Compatibility with other microinverter brands depends on the connector type and voltage rating. Check your microinverter specifications before ordering.
What Is The Nema 6-15p Plug Used For In Canada?
NEMA 6-15P is a 240V 15A plug standard used in North America. The Victron Energy NEMA 6-15P mains cord is the correct choice for connecting Victron Smart IP43 and Skylla-S battery chargers to standard Canadian 240V outlets.
Does Volts Energies Ship Power Cables Across Canada?
Yes. All power cables ship nationwide across Canada. Free shipping applies on orders over $297.
