Apollo ELECTRA 1500W (24V) Heavy-Duty Inverter
High-capacity uninterruptible power supply engineered to run entire multi-room homes and office workstations. The 24V dual-battery architecture halves electrical amperage draw, running cooler, saving battery energy, and supporting up to 2000VA surge.
Built for Heavy Loads and Extended Backup
Designed for homes and offices that require high wattage capacity and longer uninterrupted backup hours.
1500W High Capacity
Comfortably powers 5-6 ceiling fans, 8-10 LED lights, 55-inch 4K TV, 2 office workstations, and modern inverter refrigerator.
Dual-Battery 24V Architecture
24V DC input cuts electrical current in half compared to 12V systems, drastically minimizing cable heating and doubling battery storage.
Digital LCD Telemetry Screen
Front multifunction LCD displays real-time input voltage, inverter output voltage, load capacity percentage, battery bar, and error codes.
Integrated 90V–280V AVR
Wide-window Automatic Voltage Regulator stabilizes heavy sags down to 90VAC without tripping to battery, preserving battery juice.
Sub-10ms Instant Transfer
High-speed transfer relay prevents computer rebooting, network disconnections, and TV resets during sudden load-shedding blackouts.
Dual Silent Cooling Fans
Dual thermal-controlled exhaust fans maintain optimal internal temperature over extended 4–8 hour continuous load-shedding sessions.

Technical Specifications — Apollo ELECTRA 1500W
Heavy-duty factory engineering parameters verified for residential and commercial backup in Pakistan.
Why 24V is Superior for 1500W Home Backup
Learn how the 24V series architecture protects your batteries and provides longer running hours:
1. 50% Lower DC Current
At 1500W load, a 12V system draws 125 Amps creating intense wire heating. The 24V ELECTRA draws only 62.5 Amps, preventing wire overheating and reducing energy loss.
2. How to Wire 2x 12V Batteries in Series
Connect the Positive (+) terminal of Battery 1 to the Negative (-) terminal of Battery 2 using a short 25mm² jumper cable. The remaining two terminals connect to the inverter's red (+) and black (-) posts.
3. Extended Battery Lifespan
Because each battery shares the load equally, lead plates experience gentle discharge rates, extending tubular battery lifecycle by up to 40% compared to heavy 12V draws.
Verified Customer Reviews
Rated 4.9 out of 5 stars by homeowners and commercial offices across Pakistan.
"Running 5 fans, 10 LED lights, 55-inch Sony TV, and my Haier inverter refrigerator on this inverter with two 180Ah tubular batteries in DHA Karachi. Flawless performance and no battery heating."
"We installed this in our accounting firm in Blue Area, Islamabad for 4 desktop PCs, fiber router, and ceiling fans. The LCD display is very clear and shows exactly what load percentage is active."
"The 25A fast charger charges the dual batteries very quickly during 2-hour K-Electric load shedding breaks. Outstanding build quality and solid 1-year warranty backup."
Frequently Asked Questions — ELECTRA 1500W (24V)
Can the Apollo ELECTRA 1500W run a refrigerator?
Yes! The ELECTRA 1500W has a high 2000VA surge rating designed to easily start and run modern Inverter Refrigerator compressors (drawing 120W–220W running wattage) alongside your fans and LED lights.
Can I run it on a single 12V battery?
No. The ELECTRA 1500W requires a 24V DC input, which means you must connect two 12V batteries in series. For a single 12V battery setup, choose either the Apollo ALPHA 900W (12V) or Apollo ELECTRA 800W (12V).
What information does the digital LCD screen show?
The multifunction LCD provides live readouts of AC Input Voltage (from grid), Inverter Output Voltage, Total Active Load (both in Watts and visual percentage bar), Battery Level Indicator (4-stage graphical bar), and audible fault status codes.
Can I connect solar panels to ELECTRA 1500W?
The ELECTRA 1500W is a dedicated pure grid-charging home inverter. If you wish to power your home directly from solar panels without battery dependence during daytime, we recommend the Apollo Sunprox Twin or Apollo Infini V4 series.
How fast does it recharge dual 200Ah batteries?
With its selectable 25A high-current pulse charger, dual 200Ah batteries can be recharged from 50% depth-of-discharge to full capacity in approximately 4 to 5 hours of grid electricity.
