The 35mm Battery Cable is a flexible copper inverter to battery cable for 48V lithium banks. Homeowners, smallholdings and solar installers across South Africa use it on 5kW and 8kW single phase hybrid inverters. Its pure copper core keeps voltage drop low on short battery runs.
Why Choose This 35mm Battery Cable
- Heavy copper conductor carries high current to the inverter.
- Flexible stranded build routes easily inside battery cabinets.
- Insulation rated for indoor battery cabinet installs.
Compatibility And Fit For Battery Banks
As a battery inverter cable, it links 48V lithium banks to 5kW and 8kW single phase hybrid inverters. You can also run parallel links between battery modules inside one cabinet. Order matched lengths for every positive and negative run, because unequal runs split the current unevenly.
Our Battery Cable range brings together the solar battery cables we stock. Connectors and solar wire sit under Cables & Connectors. For Dyness builds, compare the ready-made Dyness battery cable pack.
Battery Cable 35mm Lengths
Choose from six lengths, each supplied without lugs fitted. Sizes run 150mm, 250mm, 450mm, 600mm, 1000mm and 1500mm. Measure between terminals first, then pick the shortest battery cable 35mm length that reaches.
Installers searching for 35mm welding cable often want this flexible 35mm2 cable for battery links. It’s not PV string cable, which needs 6mm solar wire instead. Where an inverter manual calls for a conductor larger than 35mm², a heavier lithium battery cable is needed.
Lugs Fuses And Isolation
The cable fits M8 and M10 battery cable lugs, which are sold separately. Confirm the stud size on both the battery and the inverter before ordering. Between battery and inverter, fit a 160A battery fuse or the 125A option.
A 160A battery disconnect switch lets you isolate the bank for safe maintenance. Compare more ratings under battery fuses and fuse holders. Check your inverter’s maximum battery current first, so the fuse rating matches the system.
Best Use Cases Across South Africa
- Homeowners linking a 48V lithium bank to hybrid inverters.
- Solar installers wiring parallel links inside battery cabinets.
- Farms running off-grid pumps and tools on battery power.
Loadshedding is when a weak battery link shows, because an undersized cable runs hot under evening loads. A correctly sized battery cable for inverter backup keeps fridges, lights and Wi-Fi running instead. Pair it with our range of 48V lithium batteries for a matched home backup bank.
We tell every installer to cut both battery runs to the same length and keep them short. Crimp lugs with a proper hydraulic crimper, then feel each terminal for heat after the first evening. Our professional solar installation team fits battery banks across the Vaal Triangle and Gauteng.
Warranty Compliance And Trust Details
SANS 10142-1 governs the wiring of the installation and is the electrician’s responsibility. Under the Electrical Installation Regulations, a registered person issues the Certificate of Compliance for the installation. No product certification is listed for this cable, so we never claim one.
Solar Panel Energy has supplied solar equipment for 13 years and completed 500+ jobs. Installations include a 12-month workmanship warranty, confirmed with your quote. Pay by EFT, card, cash or PayFast, and a 7-day return period applies.
