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

Ÿ Protection against over and under voltage, over current, system overload and
module over temperature.
Ÿ Fault detection with error code display.

INSTALLATION

Dayliff SunVerter B controllers are surface mounted and should be provided with an
enclosure for water and heat protection. Due to the high operating voltages proper
earthing is essential, which must be carried out by a qualified electrician.
As a rule all PV powered solar pumping systems should be provided with a PV solar
module array with a nominal output about 30% greater than the motor size. The arrays
should be wired in a combination of series and parallel connections to ensure that the
correct voltage is available into the inverter with appropriately sized PV Disconnect Circuit
Breaker and a Surge protector if applicable. It is important that the connection
arrangement is approved by the pump supplier. Connection to capacitor-less single
phase pumps should be done via appropriate capacitor box.
