Troubleshooting

1) Main screen of the "Elios4you" App never shows power produced by the photovoltaic system

Turn the production CTs (white label) about face, so that the green dot or the arrow on the inside of the CT is positioned on the

opposite side to that currently in use.

Check that the cores of the CTs do not show any signs of internal damage.

2) Power level displayed by the App is much lower than that read by the inverter

Check that the grid CTs (yellow label) are positioned around the entire bundle of phases coming from the meter as in the diagram

(see fig. 2); it is possible that the CTs may have been placed on a branch circuit.

Check that one or more CTs do not show any clear signs of damage internally.

3) Consumption detected and power produced follow the same curve

Check that the grid CT (yellow label) is positioned around the entire bundle of phases coming from the power company meter as in

the diagram; in all probability, only the cable carrying consumption data is being detected.

Check that only the phase conductor of the system passes through the two CTs: if both phase and neutral pass through, an error

will be induced.

Check that the two CTs do not show any clear signs of damage internally.

4) Power usage by the consumer appears to be detected in the grid icon

Check that the grid CTs (yellow label) are positioned on the lines leaving the relative meter, upstream of any branch made within

the electrical system.

5) There is never any indication on my system of power being supplied to the grid

Check that the grid CTs (yellow label) are positioned on the lines leaving the relative meter, upstream of any branch made within

the electrical system.

6) At night there is zero usage, whereas during the day consumption is always higher than normal

Check that the grid CTs (yellow label) are positioned on the lines leaving the relative meter, upstream of any branch made within

the electrical system.

Check for correct correspondence between the sequence of supply voltages connected to the main switch and the sequence in

which the CTs are positioned on the various conductors.

7) App shows very high levels of consumption, whereas usage by the consumer is minimal

Check that the grid CTs (yellow label) are positioned on the lines leaving the relative meter, upstream of any branch made within

the electrical system.

Turn the grid CTs (yellow label) about face, so that the green dot or the arrow on the inside of the CTs is positioned on the opposite

side to that currently in use.
