14. Solar-Log™ Meter
Operating Mode

Current transformers measure AC potential-free.

Current transformers have a defined ratio between primary and secondary current.
Solar-Log™ to calculate the power as follows:

Secundary current Isec is measured with the meter interface of the Solar-Log™

Voltage U is either configured in the Solar-Log™ or
the measured values of the inverters are being used.
Isec
Calculation of the power P by the Solar-Log™:
 (Isec x ratio) x U = P

36. Cabling Advices

Please use high quality cables:
LIYCY >=0,14mm2 or CAT 5/7 SSTP

Please consider manufacturers‘ requirements concerning UV stability and installation

For long distances, please use cables with a bigger diameter

Please use cable end sleeves for flexible wires

Please twist pairs and shielding

Please wire/cable from left to right

Please wire/cable from bright to dark colors
Wrong cabling = problem #1!
 Please work very accurately.
 Please do not try to save material.

Production:
• Based on information sent by the inverter
Consumption:
• Based on information sent by the connected consumption meter
Solar-Log™ always calculates average values within 5 minutes.
Changes and switchings only take into effect every within 5 minutes.
Please consider this when testing profiles!
Surplus:
• One profile:
production
– consumption
= surplus
• Several profiles:
production
– sum (typical nominal power of the activated profiles)

• Voltage dependent
Reactive Power Q(U)83 von 97

80. Active Power
Power reduction to a specific percentage
•To limit the inverter‘s power to the set percentage (X%) of the module‘s output
•To control Active and Reactive Power of the inverters through Solar-Log™
www.solar-log.com

81. Active Power
Reduction to a specific percentage with the calculation of self-consumption
•
Innovative solution to minimize losses from the fixed regulation (e. g. 70% or x%)
•
Only if feed-in power (production - self-consumption) exceeds the maximum
 inverters are regulated accordingly
•
Using Solar-Log™ Smart-Home functions to optimize self-consumption

97. Measurement Self-consumption
Electric plan and installation notes
Relevant points for the configuration of Solar-Log™
 Meter (S0 or RS485) has to record total consumption
 Configuration password-protected
 Define Feed-in Management type
-> customer can not manipulate Solar-Log™
 At Configuration | Devices| Configuration
define maximum AC power
and
generator power accordingly
*
 Detected meter to be configured as consumption meter
Configuration | Devices| Configuration | Meter configuration
als Verbrauchszähler konfigurieren
* This meter is not required for this function
