Soft Start tecHnoLoGy
This feature offers the following advantages:
• WhentheinverterisswitchedON,thevoltagerampsupto115VACinaround2sec.Ifthe
load was already oN at the time of switching oN of the inverter, starting surge current
demanded by certain reactive devices like motors etc. will be reduced and there will be less
likelihood of the inverter shutting down due to overload.
• IftheinverterisswitchedONfirstandthenaloadwithhigherstarting/inrushcurrentlike
SMPS / motor is switched oN, the voltage will dip momentarily and then recover to reduce
inrush / starting surge current in the load as above.

cooL Surface tecHnoLoGy
Normally, heat dissipating components are mounted directly on internal metal chassis
surface of the inverter and hence, the chassis surface may rise to unsafe touch-tempera-
ture. In this inverter, heat-dissipating components are not mounted directly on the chassis
of the unit but on PCb (Printed Circuit board) mounted heat sink and, there is air gap
between the heat sink and the chassis surface. The heat sink is cooled by load-controlled
fan. As there is no direct contact between the heat sink and the chassis, the chassis surface
remains much cooler and is safer to touch.
LoaD controLLeD cooLinG fan
Cooling is carried out by convection and by forced air circulation by load-controlled fan.
The fan will normally be off and will be switched oN automatically as follows:
• InvertersupplyingACload(s):Whenload(s)≥85W
• BatteryCharging/ACPassThroughMode:Whenchargingcurrent≥3A
