b) Voltage Stabilizer (90-280VAC) built-in active when City Power AC Input applied.

c) Overload Control active for Output Rating when system become overloaded.

d) Input-1: 12VDC * 1 Battery and start use it for 220VAC load equipment connect at output socket.

e) Connect to 1-phase AC 220V utility line for AC power stabilize output and Battery Charging (N & G line to be common with utility/city power line for safety of Inverter (IPS) and Load equipment. (advise your electrician to check N-G=0Volt or <1Volt is better, Phase + line at Left hole of the input/output socket).

f) If Solar Panel Connected:  19VDC Solar Power –> connect to 13.75VDC Charge Controller –> connect to 12VDC Battery  –> connect to 12DC Inverter –> for 220VAC Output –> connect to Light/Fan/TV/Computer at inverter output socket (universal round socket 10A provided).

h) Type: Off-Grid Inverter,

i) Lowest Battery Cut: 10.5VDC.

j) Highest Battery Cut: 13.75VDC,

h) Charging Current of Inverter (Automatic control of Charging Current):

– for Inverter Capacity: 280W (400VA), Built-in Charger 6Amp,

– for Inverter Capacity: 525W (750VA), Built-in Charger:  10Amp,

– for Inverter Capacity: 840W (1200VA), Built-in Charger:  12Amp.

i) Maintenance Call should be done – when the Inverter become faulty, then disconnect Inverter (IPS) from city-power / utility line AND bypass Inverter (IPS) direct to city-power. For inverter line Bypass to city-power, just take out the load cable plug from Inverter output socket and plug-in it to wall-socket. Very simple.
