Off-grid Stand-alone Solar Hot Water 12V DC Solar Controller 12V DC Pump

Description

This listing is for backorder only
Laing D5 Vario 38/700B Bronze Pump
Laing D5 Vario pump can be
used in a wide variety of DC applications where a
highly efficient circulation pump is required.
The single moving part in a spherical motor is a
hemispherical rotor/impeller unit. The rotor/
impeller rides
on an ultra-hard, wear-resistant
ceramic ball.
There are no conventional shaft bearings or seals.
Eliminating the possibility of bearing-play and a
potential leak path.
Provide an exceptionally long service life in excess
of 50,000 hours.
Maintenance is not necessary under normal
conditions. Even after lengthy shut down periods a
reliable start-up is virtually guaranteed.
Parts exposed to the fluid are completely corrosion
resistant even with aggressive fluids.
Speed control easily adjusts by turning a dial in the pump end. It can
be adjusted to vary the hydraulic performance and/or
the electrical power consumption.
Regardless of the setting, the pump always starts with
maximum torque. This ensures a reliable start even at
the lowest speed.
Each pump has an integrated over-temperature safety
device that shuts the pumps electronics off when
reaching the temperature limit of +203°F (95
°C).
If the over-temperature safety device is activated the
pump will restart automatically after the pump has
cooled completely.

12V DC Solar Thermal Controller
The DC solar controller is a 12V DC controller suitable for stand alone solar hot water systems equipped with up to two collector arrays or two storage tanks and can be used for numerous system types.
Can operate with 12V PV solar panel, with or without battery.
The battery type must be a lead gel battery. Other types only if suitable with the technical specifications. The battery fuse must be chosen according the cable cross-section.
Automatic identification of 12V batteries.
The controller operates with 12V DC. The pumps and valves must also operate with 12V DC.
The controller is equipped with the following features:
Intuitive operating menu with graphic symbols and four operating buttons
Illuminated display
Adjustable control values
Start function for systems equipped with tube collectors
Integrated operating hours counter for storage tank charging
Extensive functions for system monitoring that display symbols to indicate errors and faults
Integrated energy yield measurement (optional, only in conjunction with the yield measurement set)
Storage of all values even during a prolonged power supply outage
Various protective functions, such as system protection, collector protection, recooling and anti-freeze protection
Generous wiring space
Real-time clock function
