The Rapid+ 750/12V is a 550VA / 440W pure sine wave inverter for a 1RK flat, a single room or a small shop. It runs from one 12V battery and keeps a couple of fans, a few LED lights and a Wi-Fi router going through power cuts. "750" is the model number, not the VA rating.
It is the smallest Rapid+ model on the site. If you also want a TV or a laptop running for hours, step up to the Rapid+ 950/12V (700VA). If there is a fridge in the house, look at the Rapid+ 1500/12V (1125VA).
The 440 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 |
| Wi-Fi router and set-top box | 10–25 W |
| Laptop and phone chargers | 45–90 W |
A working example: two fans (140 W), three LED lights (30 W) and a router (10 W) come to roughly 180 W, about 41% of the 440 W rating. As a rule of thumb, keep the continuous load below about 350 W, which is 80% of the rating.
It is sized for lights, fans, a TV and Wi-Fi. A fridge, an air conditioner, a geyser or a heater is outside its range; for a fridge, start at the Rapid+ 1150/12V (900VA).
The Rapid+ 750/12V 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 100Ah 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 100Ah tubular battery (1,200 Wh) that works out to about 2.8 hours at 180 W and about 5.1 hours at 100 W. A 12.8V 100Ah LiFePO4 battery (assuming 90% usable) gives about 5.4 hours at 180 W. These are calculations with an assumed 85% inverter efficiency, not lab measurements; heavy loads, battery age and temperature all shorten real backup.

| Rapid+ 750/12V (this model) | 550VA / 440W | 12V | LED | 1RK or one room: fans, lights, router |
| Rapid+ 950/12V (700VA) | 700VA / 560W | 12V | LED | 1RK or compact 1BHK, tight budget |
| Rapid+ 1050/12V (800VA) | 800VA / 640W | 12V | LCD | 1BHK: fans, lights, TV, router |
| Rapid+ 1150/12V (900VA) | 900VA / 720W | 12V | LCD | 1BHK: fans, lights, TV, router, laptop |
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 750 the VA rating of the Rapid+ 750/12V?
No. 750 is the model number. The Rapid+ 750/12V is rated 550VA / 440 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+ 750/12V run?
It suits a 1RK flat, a single room or a small shop. For example, two fans (140 W), three LED lights (30 W) and a router (10 W) come to roughly 180 W, about 41% of the 440 W rating. Keep the continuous load under about 350 W.
Q: Can it run a TV, a laptop or a fridge?
A TV and a laptop, yes, alongside a couple of fans and lights; keep the total under about 350 W. A fridge is a poor fit because its compressor needs a start-up surge above the running wattage and 440 W leaves little room. Use the Rapid+ 1150/12V or larger for a fridge.
Q: Which battery should I buy for the Rapid+ 750/12V?
One 12V battery. Tubular, TGEL, SMF, gel and 12.8V LiFePO4 batteries all work. A 100Ah 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 100Ah tubular battery, using about half of the battery capacity and assuming 85% inverter efficiency, expect about 2.8 hours at 180 W and about 5.1 hours at 100 W. Switching off unused loads extends this. These are estimates, not measured results.
Q: Can I use a lithium battery with the Rapid+ 750/12V?
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 35 to 45 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+ 950/12V and Rapid+ 1050/12V?
The Rapid+ 950/12V is rated 700VA / 560 W on 12V. This model is 550VA / 440 W on 12V. The Rapid+ 1050/12V is 800VA / 640 W on 12V and suits a 1BHK flat.
Q: What happens if I overload the Rapid+ 750/12V?
The electronic resettable fuse cuts the output when the load goes past the 440 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 350 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.
