Solar DC pump station for solar water heater

1, Applications:

Advanced control functions for the Zilansolar PV pump station. The Zilansolar PV pump station is a globa-radiation-driven solar station. The high-efficiency D.C. pump is supplied and controlled directly by the current from a PV panel. As such, the standard supply connection, solar regulator, collector and accumulator sensor are no longer required. The unit is controlled by a built-in temperature sensor in the pump, which regulates and interrupts the flow rate according to the return temperature. The excess flow is taken up by the MAG.

Once the collector cools down,the unit automatically starts up again.These components allow independent and efficient operation of the unit. Hydraulic balancing, flow measurement and venting can be performed directly in the station. Using the scale, which is pre-calibrated for frost protection, the technician can set and check the exact flow-rate values on-site. Installation and venting can be carried out by one person working unassisted. Utility model protection has been granted.

2, Highlights:

<1> Designed for self-sustaining solar operation

<2> No additional costs. Solar controller and its electrical installation are not required

<3> High-efficiency D.C. pump

<4> Cost-effective one-man installation and filling of the system

<5> Multifunction ball valve strongly facilitates the filling and draining of the system

<6> Collector and reservoir sections can be separated for installation work

<7> Easy pump replacement (suction and pressure side can be shut off)

<8> Precise and rapid adjustment, without use of diagrams, charts or expensive measuring tools

<9> Function control via direct flow rate indicator of the SETTER Inline PF

<10> Visual scale in l/min, pre-calibrated for glycol blends u = 2.3 mm²/s

<11> Constant air separation during line

3, Installation position

The solar station must be installed vertically to ensure problem-free functioning of the venting unit.

4, Operation

In the collector, the intensity of global radiation directly regulates the speed (power) of the pump through the voltage generated.The flow-rate measurement is based on the proven principle of a baffle float. The basis for the air venting are special flow technology measures which accumulate the air in

the top of the venting space, from where it can be released from time to time. There are no mechanical parts, so the design ensures a long service life. At the same time, acts as a

check on whether air is building up in the system.

5, Specification:

The Zilansolar PV pump station is a type program for solar PV pump. Includes: flow phase (venting side) and return phase (pump side) ready-to-connect solar station for circulation and venting of solar circuit medium incl.mounting attachments (with utility model protection).
