Calculate the units or power wattage for an hour and multiply the number of hours you required for backup.
I want daily 3 hours of backup
Ex:
Laptops 5 average use of laptop power consumption per hour 60W (check on the battery). but desktop use 200 Watts per hour.
90*5=450W
fan*2 =60W
Tubelight=40w 550W per hour *3 1.650 KWH. (1 and a half unit)
150 AH battery
ah to watts
amps to watts 24 volt battery with 24 watts circuit then amp = 1.
100 AH battery provides 5Amps for 20 hours. 100*12=1200watts
how many watts a 150ah battery provides?
A 12 volt 150 AH battery can deliver 12volts at 150 amps for 1 hour.
A 150AH battery, if its 12 volts, can deliver 150 times 12 watt-hours, or 1800 watt-hours. that’s 1800 watts for one hour
Watthour = Ampere hour * Voltage
- Refrigerator
- TV
- AC

lead Acid batteries Flat plate battery
Deep Cycle DRY batteries
No maintenance, no gases once the lifespan completed we need to buy the new one. expensive. sealed batteries or Deep Cycle, SMF Sealed Maintenance Free or VRLA (Value Regulated Lead Acid).

Note: For fist time users always buy Inverter with Battery Combo.
UPS vs Inverter
Inverter Capacity (VA), Battery Capacity (Ah)
UPSs are further classified into three- Offline, Online, and Line interactive.
uninterrupted power supply No power loss within microseconds. but with the inverter, it can happen.
UPS Price 2k to 6k, inverter 10K-40K.
AC Current vs DC Power: DC (from powerline) flows one way but Ac (from inverter) current flows appliance to source and source to the appliance.
How to choose the best Inverter by capacity?
what we need 1700 watts for an hour. then 1700*0.8= 1360 VA nearest Inverter we need to pick.inverter capacity measured by serving capacity at each single time.
500 VA inverter cannot server to refrigerator and AC etc.
