- Myenergi Hub How do I update the firmware?
You can view your Myenergi Zappi EV charger basic controls and data on the Myenergi Hub.
If you would like to update your Myenergi Hub to the latest firmware, some details for how to update this:
The Myenergi Hub has two buttons. The steps to update the firmware:
- Unplug Power to the hub
- Press and hold the 'Download' button (right hand side)
- Keep pressing the 'Download' button while you plug the power back into the hub
- Check the status lights on the Hub – once the Power LED turns yellow, release the button
- The Power LED light should be Green and the Server LED light should be white while the firmware is downloading
- Once the download is complete the Server LED light will turn green (or blue) again
- Myenergi Hub how to change the channel? Zappi EV Charger not pairing
If your Zappi EV charger is not pairing with the Myenrgi Hub - a possibility is 'channel' on the Myenergi Hub does not match the channel on the Zappi EV Charger.
The remedy to try is to change the channel on your Myenergi Hub so it matches your Zappi EV Charger. Typically by default your Zappi EV Charger channel will be set to Channel 1 (A).
To change the Myenergi Hub Channel firstly:
Put Hub into Pairing mode
To put the hub into pairing mode, briefly press the left-hand button (Pair / Channel)
The Power LED will flash red and one of the other LEDs will be lit to indicate which channel the hub is using. The channel number is written under the LED.
Next how to Change the channel
While the hub is in pairing mode (Power LED flashing red), press and hold the left-hand button. The channel LED will cycle through the channels – Blue for channels 1-4 and White for channels 5-8
- I am installing 2 x single phase inverters across 2 different phases and the DNSP requires export limitation per phase, what should be done?
If the DNSP requires export limit on each of the individual phases then a single phase smart meter will need to be used on each phase because the three phase smart meter will not do export limitation per phase. Under this scenario please note that you will not be able to set it up as a single system in Fronius Solar.web
- Does a three phase Fronius Smart Meter manage export limitation per phase?
No, it doesn’t manage export limitation per phase. It sums up the value across all the three phases and then adjusts to export limitation
- Is it possible to have two Fronius Smart Meters connected individually to two Fronius Datamanager Cards and have it as a single system in Fronius Solar.web?
No, this is not possible because having two smart meters under a single system will lead to an incorrect visualization of the consumption values in Fronius Solar.web. However this is possible when one smart meter is set to feed-in point and the other smart meter is set to consumption path. This configuration is possible only if a combination of Fronius Datamanager 2.0 box and Fronius Datamanager 2.0 card is used.
- My customer has a 1.5kW system installed with a third party inverter brand. If he wants to upgrade the system with a Fronius Primo 5 kW inverter in addition to the existing system, where the DNSP requires 5kW export limit, can this be done by using a Fron
Yes, if your export limit is equal to or greater than the other inverter’s output capacity this can be done. Please note: The Fronius Smart Meter will not control the power output of the third-party inverter. For example: If the third-party inverter is 1.5 kW and Fronius inverter is 5 kW and there is only 5 kW allowed to export, then the export limitation value that can be set on the Fronius inverter is 5 kW.
- If there is a site where a Fronius Symo Hybrid is AC-coupled to a Fronius Symo inverter, how would you do export limitation?
Using a Fronius Smart Meter it is possible to export limit on the Fronius Symo Hybrid but not on the Fronius Symo inverter because the Fronius Smart Meter will be connected to the Fronius Symo Hybrid inverter, which in turn cannot be daisy chained with the Fronius Symo inverter.
- If there is no sufficient space on the switch board to fit the CT’s (in case of a 50 kA Fronius Smart Meter), what’s the solution?
In case of space constraints in the switch board, rope CT’s can be used. Please note that rope CT’s are voltage reference CT’s, which are smaller than current reference CT’s and can only be used along with the 480VUL Fronius Smart Meter. So, if you have proposed a system with a 50 kA Fronius Smart Meter and you have space constraints in the main switchboard, then you can solve the situation by having a 480V UL Fronius smart meter with rope CT’s.
- Is it possible to monitor the consumption of a site just by having a Fronius Smart Meter without installing an inverter?
Yes, you can use a Fronius Datamanager 2.0 box and connect the Fronius Smart Meter to it. This can then be added as a PV system in Fronius Solar.web to visualise the consumption values.
- I have a two phase site (not SWER) and I am installing a single phase inverter on one of the phases. What smart meter do I use in this scenario and can I do export limiting?
If export limit needs to be done on this site across all the phases then a three phase smart meter will need to be used. If the DNSP doesn’t require export limitation on each of the individual phases then it’s better to use a three phase smart meter because it will export limit once considering the total consumption across all the phases added together.
