Clearances
Heat must be able to dissipate from the inverter through the heatsink on the back. It is important
to consider the recommended clearances. The below table is for a single inverter only.
Multiple inverters should only be installed side by side horizontally and never vertically stacked
one above the other.
Suitable locations
Suitable locations are the south, southeast and southwest facing walls of a building or the garage.
Porches that offer sufficient shelter can also be suitable. The inverter must not be installed in a
location, where it is exposed to direct sunlight.
Wiring
5.3.1
DC Wiring
All wiring must be installed and sized in accordance with the relevant requirements of AS/NZS
3000, AS/NZS 3008.1, AS/NZS 5033 and AS/NZS 4777.1.
All DC cabling and the associated earth bonding conductors should be bundled together to avoid
induction loops. Where possible, use the so-called “leapfrog wiring” method to avoid unnecessary
cable loops and home runs.

If the leapfrog or skip wiring method is impractical, the modules can be daisy chained.
