6.6. Testing solar charging functionality
If not applicable, please refer to section 6.7.
1.
Temporarily switch off the solar panel installation.
2.
Check if the LED on the Sensor Box blinks red three times.
3. In the App, go to the Advanced settings and select Measured values .
4. Check the values for L1, L2, and L3. The measurements should only show positive values.
5. If any of these values are negative, reverse the CT clamp on the mains incoming cable and
ensure all values are positive.
6. Switch the solar panel installation back on. The Sensor Box will flash in a three phase cycle.
It will flash green if there is power generated and being fed back to the grid.
The Sensor Box flashes red if no solar energy is being generated (3 x red).
On a single phase installation, if solar energy is generated and energy is fed back to grid on
phase 1, the LED will flash 1 x green and 2 x red in succession.
7. Check if the Measured values screen in the App shows negative power values when power is
fed back into the grid by the solar panel installation.
Note: If no power is currently fed back into the grid by the solar panel installation, perform
this test procedure again when there is power fed back to the grid.
Points of attention if the App shows incorrect values while the charger is in Smart (Solar)
mode:
• Make sure the arrows on the current transformers point towards the entry point of the
main power grid.
• Make sure the current transformers L1, L2 and L3 are connected according to the phase
sequence (Sine).
• If the charger indicates deviating values, it can help to switch the CT terminals on L2 and
L3 on the Sensor Box.
• The mains input cable of the Sensor Box must be plugged into a power socket connected
to the same phase as L1 of the charger.
6.7. Updating the charger
Ratio recommends to always install available firmware updates. Firmware updates keep the
data security of the charger up-to-date and occasionally add new features.
Updates are performed sequentially. This allows the system to offer multiple updates in
succession. Always install available updates to ensures the use of the latest version. Read the
release notes on the Ratio website or in the App Stores to learn about new features and
improvements to the system.
