Daily data is always deleted
If too many inverters are connected the 5 minute interval may be too short and the data may not be shown at all.
With the firmware version as of 10.09.09 there is already a pre-setting for this:
- up to 30 inverters: Interval set at 5 minutes
- from 30 - 60 inverters: Interval set at 10 minutes
- 60 or more inverters: Interval set at 15 minutes
The serial number is not identified for transfers made via Bluetooth.
The serial number is not correctly identified if the "device name" has already been changed using SMA SunnyExplorer software. The device name must remain as per the original at the time of delivery or be configured back to it:
Example: SN: 2100005107
The format of the serial number must be SN:<EMPTY>SERIAL NUMBER.
How can the event protocol be saved?
The event protocol be saved by copying data onto the USB.
It is IMPORTANT that the option "Show event protocol on website" has been activated. Otherwise it will not been shown when copying data.
The file itself does exist on the USB stick"events.html"
How can I query the MAC or IP address from Solar-Log™?
Via the URL order "chipcfg" Mac address, IP address and standard gateway
can be queried.
Which ports are required to operate the Solar-Log™?
Port settings for the Solar-Log™ devices
- Port 21, TCP, FTP data transfer (passive)
- Port 25, TCP, SMTP email sending
- Port 53, UDP/TCP, DNS name delegation
- Port 80, TCP, HTTP web
- Port 123, UDP, NTP time server
The settings under [Export] transfer interval are always reset after the "Save" button has been pressed.
As long as no inverters have been identified the "Interval" setting cannot be changed as automatic data export can only take place when data is regularly accrued. The test transfer can however still be carried out.
Higher AC values are shown than the existing DC values.
In the value table the DC output displayed may be larger than the AC output. This is due to the fact that the data is saved internally and that the DC values are added or accumulated by the Solar-Log™. The inverter does not measure the values accurately.
Example: If the sun shines brightly during the measurement (cycle = 15 min) because there happens to be no clouds at that time, the device can also record and add the data. However if a cloud were to throw a shadow during measurement and the sky was clear during NON-measurement, this DC data would be missing from the device.
This can lead to incorrect values being present in the table. It is better to ignore these values.
Note: The AC values in the table are always correct.
Solar-Log" offers the ability to control inverters or strings (for multi-string inverters) via the kWp output.
In the daily view check the kWp box at the top right. Then the individually displayed current inverter yields are divided by their generator output and the kWp output is visible as the result. If the modules are working accurately, the kWp output should be the same even for inverters of different sizes. You can see at a glance whether your plant has been working correctly.
PV plant with 2 inverters:
Inverter 1 (INV 1) has a generator output of 3600 Wp
Inverter 2 (INV 2) has a generator output of 5400 Wp
In this display at 2 p.m. inverter 1 has 2492 W, inverter 2 has 3746 W. (Fig. 1)
In this graphic with kWp checked you can see that the value lines run across each other, i.e. the plant is working error-free. (Fig. 2)
The kWp output is calculated as follows:
INV 1: 2 p.m. current output 2492 / 3600 generator output = 0.69 kW/kWp
INV 2: 2 p.m. current output 3746 / 5400 generator output = 0.6 kW/kWp
