HelioZenit HELIOMOTION PV-4, Quick Assembly Manual

1. Acquire an outdoor underground cable long enough to reach from the 

junction box (K) on the column to the nearest fuse box inside the house. A 

1-phase system needs a cable with two wires plus a surrounding shield 

(1-phase cable), whereas a 3-phase system needs a cable with four wires 

plus the shield (3-phase cable). The thickness of the wires should be at least 

2.5mm² for cable lengths up to 40 meter or 6mm² for cable runs up to 100 

meter. Indoor cable sections can use an indoor cable of the same size and 

with the same number of conductors. Please consult your electrician for the 

exact cable to use according to local code requirements.

2. Wire the cable from the junction box (K) to the fuse box. A strong string 

can be used to pull the cable up through the bottom of the column and 

out of the hole beneath the junction box. It is recommended to pull under-

ground sections through a cable duct. The duct needs to be burried so 

that the top of the duct is 35 cm below ground. If the cable runs over bed-

rock it needs to be protected by a strong hose (or a metal U-profile).

3. Make sure that all cable sections above ground are properly attached 

and protected so the cable cannot be accidentally moved or damaged.

Sections coming out of the ground need to be protected by for example

a metal U-profile.

4. Fill out and attach the included self adhesive warning labels. These labels 

need to be provided near the solar installation, the fuse box, and the utility 

meter, to indicate the presence of on-site generation and the placement 

of the AC switch (S).

Contact a certified electrician and have them inspect the installation

and carry out the remaining tasks.

1. Make the electrical connections as illustrated on the previous page.

2. Connect the AC cable to the selected phase(s) through fuse(s) in the 

fuse box.

3. Connect the solar panels to the PV input terminals of the microinverters.

4. Turn on the AC switch (S) in the junction box to power the inverter(s) and 

solar tracker. It takes a few minutes for the tracker to find a GPS signal 

before it start to track the sun.

5. Check the status lights on the inverter(s). When a solar panel is connec-

ted its LED becomes red. When the AC side is connected and powered the 

LED starts blinking red. Grid feed-in starts after about 30 seconds during 

sunshine indicated by the LED either blinking green (optimizing output) or 

being continously green (output optimized).
