The Rapid+ 1800/12V is a 1600VA / 1280W pure sine wave inverter that runs from a single 12V battery, for a 3BHK home or a small shop. It runs on one 12V battery and has a 24×7 MCB.
Original price was: ₹14,990.00.₹10,338.00Current price is: ₹10,338.00.
The Rapid+ 1800/12V is a 1600VA / 1280W pure sine wave inverter that runs from a single 12V battery, for a 3BHK home or a small shop. More power on one battery means a heavier current draw, so battery quality and capacity matter more here than on the smaller models.
The model number 1800 is not the VA rating. Its sibling, the Rapid+ 2000/24V (1700VA), uses two batteries in series, which halves the battery current for the same load. Invertek's sizing guide pairs the Rapid+ 1800 range with a 1.5-tonne AC.
The 1,280 W figure is a resistive (bulb load) rating. Motors such as fridge compressors and pumps draw a short surge when they start, so count them a little heavier. Typical draws are below; check the label on your own appliances.
| Appliance | Typical running draw |
|---|---|
| Ceiling fan | 60–80 W (BLDC fan: 30–35 W) |
| LED bulb or tube | 9–20 W |
| 32 to 43 inch LED TV | 40–100 W |
| Wi-Fi router and set-top box | 10–25 W |
| Desktop PC with monitor | 150–300 W |
| Single-door refrigerator | 100–200 W, plus a start-up surge |
| Double-door frost-free refrigerator | 150–300 W, plus a start-up surge |
| Top-load washing machine | 300–500 W |
| Water pump (0.5 HP) | 400–600 W, with a higher start-up surge |
A working example: five fans (350 W), eight LED lights (80 W), a 43-inch TV (100 W), a router (10 W), a single-door fridge (200 W) and a desktop PC (250 W) come to roughly 990 W, about 77% of the 1,280 W rating. As a rule of thumb, keep the continuous load below about 1,020 W, which is 80% of the rating.
Invertek's sizing guide pairs the Rapid+ 2000 range with a 1.5-tonne AC, but check the AC's running wattage against the 1,280 W rating first, and remember that an AC will drain the battery quickly. Geysers, induction cooktops, room heaters and irons are best left off during a power cut.
The Rapid+ 1800/12V works with one 12V battery: tubular, TGEL, SMF, gel or LiFePO4 lithium. You can start with lead-acid and move to lithium later without replacing the inverter. The inverter is sold without a battery. A 12V 150Ah tubular battery is a common pairing at this size.
To estimate backup time, multiply battery volts by amp-hours, take about half of that as usable for a lead-acid battery, multiply by 0.85 for inverter losses, and divide by your load in watts. For a 12V 150Ah tubular battery (1,800 Wh) that works out to about 50 minutes at 990 W and about 1.4 hours at 550 W. A 12.8V 100Ah LiFePO4 battery (assuming 90% usable) gives about 1 hour at 990 W. These are calculations with an assumed 85% inverter efficiency, not lab measurements; heavy loads, battery age and temperature all shorten real backup.

Q: Is 1800 the VA rating of the Rapid+ 1800/12V?
No. 1800 is the model number. The Rapid+ 1800/12V is rated 1600VA / 1,280 W on a 12V battery system. When you compare it with other inverters, compare the VA, watt and battery voltage figures rather than the model number.
Q: What can the Rapid+ 1800/12V run?
It suits a 3BHK home or a small shop. For example, five fans (350 W), eight LED lights (80 W), a 43-inch TV (100 W), a router (10 W), a single-door fridge (200 W) and a desktop PC (250 W) come to roughly 990 W, about 77% of the 1,280 W rating. Keep the continuous load under about 1,020 W.
Q: Can it run a 1.5-ton AC?
Invertek's sizing guide pairs the Rapid+ 1800 range with a 1.5-tonne AC. A 1.5-ton inverter AC typically draws 1,000–1,400 W once running, which is close to this model's 1,280 W rating, and more at start-up. Check your AC's label, and expect short backup on batteries.
Q: Which battery should I buy for the Rapid+ 1800/12V?
One 12V battery. Tubular, TGEL, SMF, gel and 12.8V LiFePO4 batteries all work. A 150Ah tubular battery is a common choice at this size, and a larger battery gives longer backup. The inverter is sold without a battery. If you are unsure, call 9311369797 before ordering.
Q: How long will the backup last?
Backup time is usable battery watt-hours divided by your load. With a 12V 150Ah tubular battery, using about half of the battery capacity and assuming 85% inverter efficiency, expect about 50 minutes at 990 W and about 1.4 hours at 550 W. Switching off unused loads extends this. These are estimates, not measured results.
Q: Can I use a lithium battery with the Rapid+ 1800/12V?
Yes. It is lithium compatible, so you can fit a 12.8V LiFePO4 battery now or swap one in later. At full load the inverter draws roughly 105 to 125 A from the battery, so choose a battery whose BMS is rated for at least that current.
Q: How is it different from the Rapid+ 1700/12V and Rapid+ 2000/24V?
The Rapid+ 1700/12V is rated 1400VA / 1,120 W on 12V. This model is 1600VA / 1,280 W on 12V. The Rapid+ 2000/24V is 1700VA / 1,360 W on 24V and suits a 3BHK home, a shop or a small office.
Q: What happens if I overload the Rapid+ 2000/12V?
The 24x7 MCB trips when the load goes past the 1,280 W rating or the output is shorted. Switch off the heaviest appliances and switch the MCB back on; nothing needs replacing. Keep the continuous load under about 1,020 W to avoid nuisance trips.
Q: What warranty does it have?
3 years (36 months). Register the unit on the warranty registration page after installation. For service, call 9311369797.
