NASTEC USA Solar Pumps
Installation
The Nastec 4HS-MP Multi-Power pump can be installed directly to the solar panels, wind-generator or any other power supply. The optional CM-MP Remote Control / Monitoring Module is used for monitoring operations, recording operation hours and system faults, along with surface system trouble-shooting.
If the CM-MP Control Module is not used, signal cables can be used to install pump On/OFF switch along with float level control, pressure switches or high/low level alarms. REMEMBER, All the protection against over-load, over-voltage and dry running in integrated into the internal pump inverter and then submerged, thus achieving long life of all electronic components.
When equipped with the optional CM-MP Multi-Powered Remote Control module system allows:
-
Control / Monitor electric parameters:
Current, Power, Voltage and Faults,
and track running hours. -
Record and store operating hours
and all faults/alarms. -
Add pressure or flow sensor to
control constant pressure pump
performance (with variable sunlight). -
Connect a pressure or float switch.
-
Provide a digital output for remote
monitoring, control and alarms. -
A single remote control can be used
with multiple pumps as needed.
Integrated On-Board Pump Protection
The standard 4HS-MP pump includes protection against
over-voltage, over-load and dry-running. This is integrated
into the standard pump electronic circuit.
Electronic protection against dry-running avoids the use of
probes and float switches. This includes the level search
feature that checks for water level being restored and is
equipped with the auto-restart when water level returns.
Being submerged (along with the pump), the temperature
of sensitive electronic components is controlled for long life
and eliminating damage related with surface mount control.
DC/AC inverters can also generate electric fields that cause
interference with communications.
USING AUXILARY BACK-UP GENSET
If solar energy is inadequate or panels damaged in storm an
auxiliary genset can be used as emergency back-up power
to maintain pump performance.
A simple AC/DC selector is used to change the power source.
Pump Mounting
4HS-MP MultiPower pumps are able
to be installed both vertically and
horizontally. The outlet must never
be lower than the horizontal axis.
For proper cooling if 4HS-MP is not to
be installed in a well pipe, it will be
necessary to utilize a cooling sleeve or
casing pipe to maintain the minimum
speed and flow of water for cooling.
