Installation; Operating Conditions - DAYLIFF SUNVERTER 4 Installation & Operating Manual

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.
• 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.
Ÿ Power saving mode (CRUISE) - limit the maximum AC input power, hence saving
energy.

INSTALLATION

Dayliff Sunverter 4 controllers are surface mounted and should be provided with a housing
for water and heat protection. 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 should be derated by 10% for every 1,500m increase in height
***When operating in a small enclosed space, such as a cabinet, ensure the inverter is adequately cooled to prevent high internal temperature.
