Installation on large sites can come with problems. This article offers anticipated typical installation issues.
Before you contact the support with your question, please check the following:
- Fuses – Check whether the power supply at the meter and the power supply at the Equalizer is working.
- Wiring – Check whether the wiring conforms to the wiring diagram, especially if changes have been made to the wiring or if the Equalizer has not worked properly before.
- Firmware - Make sure that the Easee Equalizer has the latest firmware version installed.
Equaliser does not report current or voltage values
If the Equalizer is online but does not show any current or voltage values, the wiring may be faulty. Check these points:
- Are the wires of the power supply connected to the corresponding terminals of the Modbus adapter (1 to V+ and 2 to V-)?
- Are the wires of the power meter connected to the corresponding terminals of the Modbus adapter (A to A, B to B and S to G)?
Equalizer does not show any meaningful values
If the equaliser displays random, seemingly nonsensical values with possibly large fluctuations, please check the following:
- Are there any circuits at the charging station where there are no chargers, such as Easee Ready devices?
- If so, in the Installer App, press Update existing site.
- Select the location.
- Expand Site structure (if not already expanded), and press the Equalizer.
The Equaliser screen opens. - Press Load balancing circuits. If the empty circuit is on, turn it off.
- Fluctuations in the values can also occur due to a poor Wi-Fi connection.
Equalizer displays negative values
Negative values on the Equalizer usually indicate power generation via a photovoltaic system ("solar").
If no PV system is installed and the Equalizer still shows negative values, check the following points:
- Make sure that the coils or clamps used to measure the current flow are installed in the correct direction (towards the location/consumer). Use the arrow engraved on it to check in which direction the current flow is measured.
- Check that the wires of the clamps are connected to the appropriate terminals (L1 - S1 to 1, S2 to 2, L2 - S1 to 3, S2 to 4, etc.).
- Make sure that the current and voltage measurements correspond to the same phase.
For example, L1 must be connected to terminal 10 for the voltage measurement and to terminals 1 and 2 for the current measurement. If L1 is connected to terminal 10 for voltage measurement but to terminals 3 and 4 for current measurement, this will result in incorrect values.
Equalizer shows disproportionate values
The Equalizer may show values that are proportionally much too large or much too small. If this is the case, please check
- The primary and secondary ampere ratio on the power meter. This ratio must match the ratio of the coil or clamp. For example, if you have a CT with a ratio of 100:1, you need to configure the power meter so that the primary amperage is 100 A and the secondary amperage is 1 A.
There is no load balancing
If the Equalizer is online but not load balancing between circuits, check if network communication is blocked. Some networks have a default setting that blocks communication between local devices.
Equalizer can not be configured
If you cannot configure the equaliser after installation, please check:
- Where the NFC antenna is located on your smartphone. This may vary from model to model and therefore contact may be affected if the distance is too great.
- You may not have access to the location. Ask the administrator of the location to grant you access.
