Technical Training Topics
1. Why an EMS+?
1.1 Local flexibility
1.2 Market Flexibility
The grid must always be in balance: 230 Volt / 50 Hz
Various market mechanisms, especially large industrial installations
Access to these markets
You get paid for your participation
Can sometimes exhibit behavior that does not seem “logical” or “as expected”!
For example, injection into the grid when prices are negative

4. How can I monitor my installations?
Some useful charts you can request:
-> NormalModeAndHealthy: quality of the connection/control (1 = good)
-> MeterPower: data from the current clamps (energy meter)
-> GridPower: data from the digital meter (should be the same as MeterPower)
-> ConsumptionElectricityPrice: Day-Ahead price +/- €0.15/kWh charges for consumption
-> InjectionElectricityPrice: Day-Ahead price for injection, according to energy contract terms
-> MonthPeak: Current monthly peak of digital meter
-> Battery State of Charge: Battery percentage
-> FcrActive: FCR active (=1), or FCR not active (=0)
-> PowersetpointBatError: how much the battery deviates from the requested setpoints
5. Is FlexiO controlling the installation and how is the connection quality with the inverter?
The best graph you can use for this purpose is the ‘NormalModeAndHealthy’ graph. This is the result for a combination of criteria such as:
Online/offline
EMS mode
Connection to the inverter
EMS steering
…
The graph should always show 1. If it’s not 1 you can zoom in on the period where it is not 1 and select the general graph (or other) to find out what happened at that exact moment.
6. Are the savings of last month realistic?
Low battery savings?
Energy contract not in accordance with metering situation
The battery is the cause of a monthly peak increase
Negative rate savings?
The currently set contract is worse than the average market price
Low Solar savings?
Is the production being measured?
Is the production amount in order?
7. What are the most common causes of major ‘powersetpointBatErrors’?
Incorrect settings in ‘device details’
Mismatch min soc FlexiO versus settings in the battery inverter
Huawei maintenance cycles (especially in cold and humid spaces)
8. What is the definition of the 'max reserved soc' setting in device detail?
The 'max reserved soc' is the maximum percentage of capacity that FlexiO may reserve for monitoring the capacity tariff. The lower this setting is set, the less FlexiO may take the capacity tariff into account. On the other hand, increasing the default setting of 20% is not recommended, except for very specific use cases.
Example: max reserved soc (30%) = min soc (10%) + max reserved soc (20%)
Note: FlexiO will only reserve this max capacity as soon as there is something to gain. FlexiO takes into account the consumption profile and the technical capabilities of the hardware setup.
9. Do you notice positive homeload? Are the existing solar panels also accounted for in retrofit PV?
Is the inverter model detected in the diagnostics the same as set in ‘device details’?
Are the battery settings definitely correct? Watch out for Huawei S0 exceptions
Check minimum SOC, does this correspond with settings in the inverter?
Leave max reserved SOC at the default value of 20%
Is the connection power correctly set?
10. The monthpeak increased for no apparent reason, what happened?
11. Huidige bugs & know how’s
11.1 P1 error
Na wijzigingen met P1 -> FlexiObox rebooten om P1 detectie te heractiveren.
11.2 TELENET
Softreboot leads to the solution if the FlexiObox is not yet equipped with the latest firmware.
11.3 Omvormermerk specifiek
HUAWEI
Do not perform master/slave configurations. Disconnect the slave inverter from the master and use 'unbiased estimators'. Through the FlexiO app, the user can see all the data.
SOLIS:
Correct Solis datalogger firmware
Correct inverter firmware
S6 and some S5 models are equipped with an additional serial connection.
SOLAREDGE: 'Time of use' user settings override the FlexiO code (diagnosis: powersetpointBatError)
GOODWE: Pay attention to the minimum SOC setting. Goodwe uses the term max discharge 90%. This corresponds to a minimum SOC of 10%. Do not adjust this (default) setting in the inverter!
12. Compare MeterPower (data clamps) met GridPower (data digital meter)
13. How can I determine if there is a min soc mismatch?
14. Why does the solar production not match reality?
Power in and out of the battery is known
Power in and out of the grid is known
Solar production power is not measured with a battery inverter
The homeload and solar production are both calculated values
The solar energy is not lost but is processed in the homeload
