Time-Controlled Generator Requesting - SMA SUNNY ISLAND 3.0M Installation Manual

SMA Solar Technology AG
Loads in a three-phase system:
The generator management considers the total load of all phases. It does not monitor single phases in three-phase
systems. If the switch-on power limit is exceeded, the generator management requests the generator.
Time-based procedure of the load-dependent generator request:
If the switch-on power limit is reached, the generator management requests the generator. If the load then drops to the
switch-off power limit, the generator management resets the generator request after the minimum run time. The generator
management does not record the load as an instantaneous value. The generator management calculates the load during
the averaging time 235.12 GnPwrAvgTm. The greater the averaging time that you set, the less the generator
management reacts to load peaks.
Generator run times:
The warm-up, minimum and power-down times are adhered to after the generator start. The power of the generator is not
immediately available in the stand-alone grid. Each start also means that the generator runs for at least the warm-up time,
minimum run time and power-down time.
Procedure:
1. Log in to the communication product as Installer (see the user manual of the communication product) or switch to
expert mode on the Sunny Remote Control (see the Sunny Island operating manual).
2. Select the parameter Generator request via power on / 235.09 GnPwrEna and set to Enable. This will
activate the load-dependent generator request.
3. Select the parameter Generator start load limit / 235.10 GnPwrStr and set to the switch-on power limit.
4. Select the parameter Generator shutdown load limit / 235.11 GnPwrStp and set to the switch-off power limit.
5. Select the parameter Averaging time for generator request based on power / 235.12 GnPwrAvgTm and
set to the averaging time with which the generator management calculates the average power.

Time-Controlled Generator Requesting

If the generator is requested dependent on time, it is requested on certain days for a set duration
(see Section 9.4 "Setting Time-Controlled Functions", page 100).
Procedure:
1. Log in to the communication product as Installer (see the user manual of the communication product) or switch to
expert mode on the Sunny Remote Control (see the Sunny Island operating manual).
2. Select the parameter Time-controlled generator operation / 235.13 GnTmOpEna and set it to Enable.
3. To set start date and start time on the Sunny Remote Control, set the parameter 235.14 GnTmOpStrDt to the
desired start date and the parameter 235.15 GnTmOpStrTm the desired start time.
4. To set the start date and start time on the communication product, select the parameter Start time for
time-controlled generator operation and set the desired start date and time of the generator.
5. Select the parameter Run time for time-controlled generator operation / 235.16 GnTmOpRnDur and set it
to the desired duration.
6. Select the parameter Repetition cycle for time-controlled inverter operation / 235.17 GnTmOpCyc and set
it to the desired repetition cycle.
