2.2. Mechanical Installation

Observe the following instructions when mounting and installing the THEIA HE-t inverter on

a suitable site. This is crucial to maintaining the efficiency of the inverter!

WARNING: Ensure a suitable mounting surface!

Correct installation prevents the inverter from falling from the wall. The mounting

surface must be suitable for the weight (20-22 kg / 44-49 lbs.) and temperature (90°

C / 194° F) of the inverter.

CAUTION: Ensure a suitable installation site!

Protect the inverter from flammable and explosive environments, as the inverter

heat sink can reach temperatures of up to 90° C / 194° F during long-periods of high

performance operation.

• Avoid enclosed areas with poor air flow! Sufficient ventilation is needed to prevent

temperature build up inside the inverter and hence possible power losses.

Observe the minimum distances specified below to maintain optimal cooling.

Figure 2.2.1: Minimum distances for optimum

cooling

1. 400 mm / 15.75 inches

2. 300 mm / 11.81 inches

3. 150 mm / 5.91 inches

4. 150 mm / 5.91 inches

CAUTION: Avoid installations with direct exposure to sunlight!

Direct sunlight may cause yield losses; direct sunlight causes increased internal

temperatures that can lead to reduced power output.

• For optimal operating conditions, the ambient temperature must be between -25° C & +65°

C / -13° F & 149° F, and non-condensing relative humidity between 4 % and 99 %.
