Description
COMBI-PRO-MAX is a device that combines the functions of circuit
breaker protection, a temporary surge protector and island mode
activation control in photovoltaic generation inverters. It is valid for single-
phase, three-phase and two-phase installations.

When the backup mode is activated in Huawei SUN2000-(3KTL-
L N/L PE
12KTL)-M1, there is no three-phase voltage generation. Single-phase
generation takes place between L1 and L2. COMBI-PRO-MAX connects
L2 to N and to PE respectively and therefore power is supplied only to
the loads connected between L1 and N. Loads connected between L2
and N and L3 and N will not be supplied (even if the inverter is generating
on L2 as well). Three-phase loads should not be connected to these
inverters when the backup mode is intended to be used. This operating
characteristic, intrinsic to the inverter and independent of Combi-Pro-
Max, makes a full backup with the three-phase inverter impossible.

In the event of detecting a power cut or an anomaly in the power

supply (overvoltage, lack of phase...) it will disconnect the loads
connected downstream of the COMBI-PRO-MAX from the supply
network, connect the neutral of the solar inverter to earth and send
the island mode activation signal to the solar inverter, reactivating the
supply to these loads if the conditions allow it ( enough solar energy,
battery charge). Connecting the neutral to the installation's earth
ensures the correct operation of the earth leakage circuit breakers,
ensuring the protection of people in this situation.
When the mains power supply returns to normal, for at least 3
minutes, the equipment will proceed to remove the island mode
activation signal and reconnect the loads downstream of the COMBI-
PRO-MAX to the mains.

It has a status indicator LED which, depending on the colour and
flashing rate, shows the status of the equipment. It also incorpora-
tes a switch that can be used to activate the island mode manually,
which is very useful in the initial start-up of the equipment, mainte-
nance of the installation and special working conditions.

MODE".
OR THE INSTALLATION
Before starting, disconnect power and work with the proper
tools, THIS DEVICE MUST BE INSTALLED BY A QUALIFIED
PROFESSIONAL.
Once installed, the parts connected to the electrical power suply
must be covered so that they are not accessible.
If the equipment is used or modified outside the
manufacturer' s specifications, safety may be compromised,
exempting Toscano from any responsibility for improper
use. The interior of the equipment should only be
handled by our technical service personnel.
In the event of a trip due to overcurrent, short-circuit or manual dis-
connection, the unit will not automatically reset or activate island
mode and will remain in that state until the user manually raises
the handle.
Loss of power supply:
When the mains power supply is lost, the unit triggers the MCB, discon-
necting the loads connected downstream of it, connecting the neutral
of the generator to earth at the same time and after this, it will activate
the solar inverter' s island mode activation signal. The activation time of
the equipment is 2 seconds, but the time needed for the solar inverter
to activate the output depends on the model and the operating condi-
tions. In this operating mode, the MCB handle can be raised manually,
so that in the event that the power loss has been caused by overcon-
sumption and consequent cut-off by the meter, the installation can be
reset without the need to manipulate the meter. Contact your supply
company to find out how to reset the meter. When the handle is raised,
the island mode is automatically deactivated and will be reactivated if it
is lowered again.
Overvoltage:
When the voltage exceeds the voltage established in the standard,
the equipment trips the MCB. The time it takes to start tripping
will depend on the level of overvoltage detected (according to the
specifications of the UNE-EN50550 Standard). Once the MCB has
tripped, the island mode of the solar inverter will be activated in the
same way as indicated in the 'Loss of power supply' section, except
that the handle cannot be raised manually. When the voltage drops
below 255V and is maintained for at least 3 minutes, the unit will
reset the MCB by reconnecting the voltage to the mains.
