Please leave at least 300mm clearance around the sides and top of the Inverter and approximately
200mm at the base as this will aid the natural cooling of the Inverter. The air vents on the underside of
the WM1200 also need to be kept clear of obstructions.

We suggest that you house your Inverter and other power generating equipment in a purpose built shed
sited remotely from the home, and as far away as possible from any radio transmitters or receivers. Also
make sure that the exhaust from your generator or other sources of heat or fumes are kept well away
from the WM1200. SEIA (Sustainable Energy Industry Association (Australia) Ltd) installation
guidelines must be followed.
You must have a suitable 12V DC battery bank that is maintained and operated to the battery
manufacturer’s recommendation. To ensure operation to WM1200 specification, the battery bank
should have a minimum capacity of 500 ampere hours at the 100 hour discharge rate 12V systems (ask
your supplier if in doubt). Smaller capacity batteries can be used but may result in degraded
performance of the WM1200 under heavy surge conditions.
