The Rapid+ 1850/24V is a 1700VA / 1300W pure sine wave inverter on a 24V system, so it needs two 12V batteries in series. It has a 24x7 MCB and suits a 3BHK home, a shop or a small office.
The model number 1850 is not the VA rating; this unit is 1700VA. Compared with the 12V version, the 24V design halves the battery current for the same load, which is easier on the batteries. Do not confuse it with the Rapid+ 1700/12V, a 1400VA unit on 12V.
The 1,300 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), ten LED lights (100 W), two TVs (160 W), a router (10 W), a single-door fridge (200 W) and a desktop PC (250 W) come to roughly 1,070 W, about 79% of the 1,360 W rating. As a rule of thumb, keep the continuous load below about 1,090 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 1,360 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+ 2000/24V is a 24V system, so it needs two 12V batteries connected in series. Tubular, TGEL, SMF, gel and LiFePO4 lithium all work. Connecting batteries in series raises the voltage, not the capacity: two 12V 150Ah batteries make a 24V 150Ah bank. The inverter is sold without batteries.
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 two 12V 150Ah tubular batteries in series (3,600 Wh) that works out to about 1.4 hours at 1,070 W and about 2.5 hours at 600 W. A 25.6V 100Ah LiFePO4 battery (assuming 90% usable) gives about 1.8 hours at 1,070 W. These are calculations with an assumed 85% inverter efficiency, not lab measurements; heavy loads, battery age and temperature all shorten real backup.

|---|---|---|---|---|
| Rapid+ 2000/12V (1600VA) | 1600VA / 1280W | 12V | LCD | 3BHK or small shop on one 12V battery |
| Rapid+ 2000/24V (this model) | 1700VA / 1360W | 24V | LCD | 3BHK, shop or small office on 24V |
| Rapid+ 2500/24V (2250VA) | 2250VA / 1800W | 24V | LCD | Large home, shop or clinic |
| Rapid+ 3000/24V (2650VA) | 2650VA / 2120W | 24V | LCD | Clinic and office grade |
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 1850 the VA rating of the Rapid+ 1850/24V?
No. 1850 is the model number. The Rapid+ 1850/24V is rated 1700VA / 1,300 W on a 24V 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+ 1850/24V run?
It suits a 3BHK home, a shop or a small office. For example, five fans (350 W), ten LED lights (100 W), two TVs (160 W), a router (10 W), a single-door fridge (200 W) and a desktop PC (250 W) come to roughly 1,070 W, about 79% of the 1,300 W rating. Keep the continuous load under about 1,090 W.
Q: Can it run a 1.5-ton AC?
Invertek's sizing guide pairs the Rapid+ 1850 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 1,360 W rating, and more at start-up. Check your AC's label, and expect short backup on batteries.
Q: How many batteries does the Rapid+ 1850/24V need?
Two 12V batteries connected in series to make a 24V bank. Tubular, TGEL, SMF, gel or LiFePO4 all work. Series connection doubles the voltage, not the capacity: two 12V 150Ah batteries give a 24V 150Ah bank. The inverter is sold without batteries.
Q: How long will the backup last?
Backup time is usable battery watt-hours divided by your load. With two 12V 150Ah tubular batteries in series, using about half of the battery capacity and assuming 85% inverter efficiency, expect about 1.4 hours at 1,070 W and about 2.5 hours at 600 W. Switching off unused loads extends this. These are estimates, not measured results.
Q: Can I use a lithium battery with the Rapid+ 1850/24V?
Yes. It is lithium compatible, so you can fit a 25.6V LiFePO4 pack (or two 12.8V batteries in series) now or swap one in later. At full load the inverter draws roughly 55 to 65 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+ 2000/12V and Rapid+ 2500/24V?
The Rapid+ 2000/12V is rated 1600VA / 1,280 W on 12V. This model is 1700VA / 1,360 W on 24V. The Rapid+ 2500/24V is 2250VA / 1,800 W on 24V and suits a large home, a shop or a clinic.
Q: What happens if I overload the Rapid+ 2000/24V?
The 24x7 MCB trips when the load goes past the 1,360 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 1,090 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.
