The SmartStart allows a generator with auto-start to
be controlled by the PSk3 system.
The SmartStart is connected to the PSk3 controller
via a supplied made-up cable. The cable provides
power and signalling between the PSk3 and
SmartStart.
Depending on how you congure the PSk3 the
system will switch the generator on and o.
Inside the SmartStart housing is a space for an
NP7-12 battery. The battery is charged by the PSk3
during normal solar or grid operation. The battery
provides power to the PSk3 logic boards to allow
control of the system even during nighttime or when
a generator is switched o. An example of why the
battery is required would be for a 02:00 (2am) start
of pumping.
9.12 .2 Generator compatibility
In order to use this feature the generator must
have a two wire autostart function, the SmartStart
provides a potential-free switching contact that is
closed when the generator requirement is triggered.
The maximum switching capability for the relay
contact is 250 V AC / 30 V DC, 2A.
Refer to your generator supplier for more
information on autostart.
9.11 PV Protect 1000-125 for PSk3-7 to
PSk3-15
The LORENTZ PV Protect is a surge protective
device (SPD) to be used with PSk pump systems. It
is installed on the DC input line close to the pump
controller.
The PV Protect provides an enhanced level of
protection from electrical surges (e.g. indirect
lightning strikes). For eective operation it requires a
reliable ground connection.
The use of a properly sized DC disconnect switch is
an important safety measure and obligatory for a
professional installation of a solar pumping system.
a
CAUTION – Never use this product
without a PV Disconnect 1000-40-5!
For more information on installing, wiring and
technical specications please refer to the PV Protect
manual.

9.10 PV Combiner 1000-125-4 for PSk3-7 to
PSk3-15
The LORENTZ PV Combiner is a PV connection
box to be used with PSk3 pump systems. The
box is designed to combine up to 4 DC input
strings in parallel coming from multiple “PV
Disconnect-1000-40-5” and connect them to the
pump controller.
The use of a properly sized DC disconnect switch is
an important safety measure and obligatory for a
professional installation of a solar pumping system.
a
CAUTION – Never use this product
as a replacement for the PV Disconnect
1000-40-5!
For more information on installing, wiring and
