CONTROLLER FUNCTIONALITY
The controller offers the following control functions:
• Settable minimum and maximum frequency and open circuit voltage.
• Display of operating parameters including frequency, voltage, amperage, input
power and pump speed.
• Display of historical data including energy generation, maximum power and
operating times.
• Protection against over and under voltage, over current, system overload and
module over temperature.
• Fault detection with error code display.
• Selectable hybrid modes that prioritise solar supply as well as maximise output
through optimal blending of both power supplies
INSTALLATION
Dayliff Sunverter 3 controllers are surface mounted and should be provided with a
housing for water and heat protection. They must also be provided with a circuit
breaker between the PV modules and controller. Due to the high operating voltages
proper earthing is essential, which must be done by a qualified electrician. As a rule, all
PV powered solar pumping systems should be provided with a solar module array with a
nominal output about 30% greater than the motor size. In hybrid applications, higher
array MPP voltage is specified to allow achievement of larger solar supply share of
hybrid power supply. The arrays should be wired in a combination of series and parallel
connections to ensure that the correct voltage is available into the inverter. It is
important that the connection arrangement is approved by the pump supplier.

***If the altitude is over 2,000m, the rated output current of the inverter should be derated by 10% for every 1500m increase in height.
