Installing Solar Power Inverter
Inverter failure due to improper installation will void the inverter warranty.
Consider the following when determining where to install the inverter.
WARNING: BURN HAZARD
Do not install in a location where people can accidentally come into contact with the inverter.
High temperatures can be present on the inverter, causing a potential burn hazard.
In extreme condition, the inverter chassis can reach temperatures about 70°C, which can cause skin burns
if accidentally touched. Ensure that the inverter is located away from normal traffic areas.
• Excessive debris (such as dust, leaves and cobwebs) can accumulate on the unit, interfering with
wiring connections and ventilation. Do not install in a location where debris can accumulate (under
a tree, for example).
• Make sure that the wall is strong enough to handle the weight of the solar power inverter. Reinforce
the wall as required for a secure installation.
• Make sure that ventilation of the solar power inverter is unobstructed. Keep the clearance on the
upper of the solar power inverter more than 300 mm, the lower more than 500 mm and the left and
right sides more than 150 mm each.
• Make sure that the lower side of the solar power inverter has 1500 mm and the front side has 700
mm clearance for the electrician to operate.
• Make sure that the solar power inverter is installed plumb and level.
• Never install the solar power inverter upside down.
• Never install the solar power inverter horizontally or tilted.
To minimize copper losses, the wire lengths between the PV array and the inverter and between the
inverter and the Main Utility Service Panel are kept to a minimum.
The maximum distances will depend on wire gauges and the PV array output voltages.
