The Rapid+ 1250/12V is a 1050VA / 840W pure sine wave inverter for a 2BHK home. It runs on one 12V battery and has an electronic resettable fuse.
Original price was: ₹8,990.00.₹6,200.00Current price is: ₹6,200.00.
The Rapid+ 1250/12V is a 1050VA / 840W pure sine wave inverter for a 2BHK home. It runs fans, LED lights, a TV, a computer and Wi-Fi from a single 12V battery, and its lithium-compatible charger means you can start with a tubular battery and move to lithium later without changing the inverter.
Overload protection here is an electronic resettable fuse rather than an MCB. If a fridge is part of your load, the Rapid+ 1500/12V (1125VA) or the Rapid+ 1700/12V (1400VA) leaves more room.
The 840 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 |
| Laptop and phone chargers | 45–90 W |
| Desktop PC with monitor | 150–300 W |
| Single-door refrigerator | 100–200 W, plus a start-up surge |
A working example: four fans (280 W), six LED lights (60 W), a 43-inch TV (80 W), a router (10 W) and a laptop (65 W) come to roughly 495 W, about 59% of the 840 W rating. As a rule of thumb, keep the continuous load below about 670 W, which is 80% of the rating.
It is not meant for air conditioners, geysers, induction cooktops, room heaters or irons. Those draw 1,000 W or more and need a larger inverter.
The Rapid+ 1250/12V 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 1.5 hours at 495 W and about 3.1 hours at 250 W. A 12.8V 100Ah LiFePO4 battery (assuming 90% usable) gives about 2.0 hours at 495 W. These are calculations with an assumed 85% inverter efficiency, not lab measurements; heavy loads, battery age and temperature all shorten real backup.
| Model | Rated capacity | Battery voltage | Display | Suits |
|---|---|---|---|---|
| Rapid+ 1150/12V (900VA) | 900VA / 720W | 12V | LCD | 1BHK: fans, lights, TV, router, laptop |
| Rapid+ 1250/12V (this model) | 1050VA / 840W | 12V | LCD | 2BHK: fans, lights, TV, computer |
| Rapid+ 1500/12V (1125VA) | 1125VA / 900W | 12V | LCD | 2BHK with a single-door fridge |
| Rapid+ 1700/12V (1400VA) | 1400VA / 1120W | 12V | LCD | 2BHK with fridge and extra load |
The inverter carries a 3-year (36-month) warranty. Register it on the warranty registration page after installation. Shipping is free on all orders, with standard delivery in 5–7 days.

Q: Is 1250 the VA rating of the Rapid+ 1250/12V?
No. 1250 is the model number. The Rapid+ 1250/12V is rated 1050VA / 840 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+ 1250/12V run?
It suits a 2BHK home. For example, four fans (280 W), six LED lights (60 W), a 43-inch TV (80 W), a router (10 W) and a laptop (65 W) come to roughly 495 W, about 59% of the 840 W rating. Keep the continuous load under about 670 W.
Q: Can I run a computer and a fridge together?
Only if the total stays under about 670 W. A desktop PC with monitor (150–300 W), a single-door fridge (100–200 W plus a start-up surge), fans and lights get close to that. For that combination the Rapid+ 1500/12V has more headroom.
Q: Which battery should I buy for the Rapid+ 1250/12V?
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 1.5 hours at 495 W and about 3.1 hours at 250 W. Switching off unused loads extends this. These are estimates, not measured results.
Q: Can I use a lithium battery with the Rapid+ 1250/12V?
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 70 to 80 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+ 1150/12V and Rapid+ 1500/12V?
The Rapid+ 1150/12V is rated 900VA / 720 W on 12V. This model is 1050VA / 840 W on 12V. The Rapid+ 1500/12V is 1125VA / 900 W on 12V and suits a 2BHK home that includes a single-door fridge.
Q: What happens if I overload the Rapid+ 1250/12V?
The electronic resettable fuse cuts the output when the load goes past the 840 W rating or the output is shorted. Remove the extra load and reset it; there is no fuse to replace. Keep the continuous load under about 670 W.
Q: What warranty does it have?
3 years (36 months). Register the unit on the warranty registration page after installation. For service, call 9311369797.
