How long will a lithium IPS run during Dhaka load shedding? Here is real-world runtime data for HiTHIUM systems.

For a deeper look at pairing lithium IPS with solar panels for unlimited runtime during outages, see our solar IPS guide for Bangladesh.

HeroEE Light 1 (1004Wh) Runtime

4 LED lights + 2 fans + WiFi (120W): 7-8 hours
6 lights + 3 fans + TV + WiFi (200W): 4-5 hours
Refrigerator + lights + fan (250W): 3-4 hours

HeroEE 2 (2kWh) Runtime

Essential home backup (250W): 7-8 hours
Home office (200W): 9-10 hours

MaxPower 8 (8kWh) Runtime

Full home backup (500W): 14-16 hours
Home + AC (1500W): 5-6 hours

In Dhaka, load shedding lasts 1-4 hours. Use our Watt Calculator to find the right capacity.

Real Dhaka Load Shedding Scenarios

In Dhaka, load shedding typically lasts 1-4 hours depending on the area. A HeroEE Light 1 easily covers most shedding events for essential appliances. For areas like Mirpur, Uttara, or Old Dhaka where outages can last 6-8 hours, a HeroEE 2 or MaxPower 8 is recommended.

Tips to Maximize Runtime

Use LED bulbs (consume 80% less than incandescent)
Run ceiling fans at medium speed instead of high
Unplug non-essential devices during load shedding
Keep the IPS battery charged above 50% before expected outages
Consider adding a solar panel to recharge during the day

Real Lithium IPS Runtime Data During Dhaka Load Shedding

Based on real-world testing with HiTHIUM HeroEE series systems during typical 1-3 hour power outages in Dhaka, here is the runtime data you can expect.

HiTHIUM HeroEE Light 1 (1kWh) Runtime

4 ceiling fans + 4 LED lights + 1 TV: 5-7 hours
2 ceiling fans + 3 LED lights + 1 laptop: 8-10 hours
1 ceiling fan + 2 LED lights + 1 router: 12-15 hours
Single light + phone charging: 35-40 hours

HiTHIUM HeroEE 2 (2kWh) Runtime

4 fans + 6 lights + 1 TV + 1 refrigerator: 4-6 hours
4 fans + 6 lights + 1 TV: 6-8 hours
2 fans + 4 lights + 1 TV + 1 laptop + WiFi: 8-10 hours

HiTHIUM MaxPower 8 (8kWh) Runtime

Full home (6 fans, 10 lights, 2 TVs, fridge, 1 AC): 3-5 hours
Essential appliances (4 fans, 8 lights, 1 TV, fridge): 8-12 hours

Factors Affecting Runtime

Actual runtime varies based on battery age, ambient temperature, inverter efficiency, and connected load type. For an accurate estimate for your home, visit the Banani showroom.

LiFePO4 Battery Runtime During Dhaka Load Shedding

Dhaka faces frequent load shedding, especially during summer months. Understanding how long a lithium IPS can power your home during these outages is essential for choosing the right system.

How Long Does a 1kWh Lithium IPS Last?

A 1kWh lithium IPS (like the HiTHIUM HeroEE 1) can power:

6-8 LED lights + 2 ceiling fans + 1 TV + WiFi router: 3 to 5 hours
1 laptop + 1 WiFi router + a few phone chargers: 6 to 8 hours
1 refrigerator + 1 TV + 3 LED lights: 2 to 3 hours

Most load shedding in Dhaka lasts 1 to 3 hours per event. A 1kWh IPS covers the majority of outages for a typical home.

What About 2kWh and 16kWh Systems?

A 2kWh lithium IPS (HeroEE 2) doubles the runtime and can also power a small AC unit for 1-2 hours. For homes with longer outages or higher power needs, the 16kWh system can run an entire home — including multiple ACs, fridge, lights, fans, and internet — for 8 to 12 hours continuously.

Load Shedding Patterns in Dhaka

Based on recent patterns, Dhaka experiences:

Summer (April-September): 1 to 3 hours daily, often split into 2 events
Monsoon (June-August): 30 min to 2 hours, less frequent
Winter (November-February): Minimal shedding, 0 to 1 hour weekly

A lithium IPS with LiFePO4 technology handles all of these scenarios efficiently, recharging fully in 2-3 hours and lasting 11,000+ charge cycles (30+ years of daily use).

Battery Capacity vs Runtime: Real Bangladesh Data

The actual runtime of a lithium IPS depends on three factors: battery capacity (kWh), connected load (watts), and inverter efficiency (~90%). The formula is simple: runtime (hours) = (battery capacity × efficiency) ÷ load. For a 2kWh HiTHIUM HeroEE 2 running 200W load: (2000 × 0.9) ÷ 200 = 9 hours.

Bangladesh load shedding patterns (verified from DESCO/DPDC data + HiTHIUM customer surveys):

Dhaka urban: 1-2 hours daily, mostly evening peak (6-10 PM)
Dhaka suburbs (Mirpur, Uttara): 2-3 hours daily, mixed morning + evening
Chittagong: 1-3 hours daily, often during summer AC peak
Sylhet, Khulna, Rajshahi: 3-5 hours daily during summer; 1-2 hours winter
Rural Bangladesh: 5-8 hours daily common, especially during monsoon irrigation season

Which HiTHIUM IPS Fits Your Load Shedding Schedule?

Outage Duration	Recommended HiTHIUM Unit	Capacity	Runs Typical Home Load
1-2 hours	HeroEE Light 1	1,004Wh	3-5 hours (WiFi, fans, lights)
2-4 hours	HeroEE 2	2kWh	4-8 hours (full home essentials)
4-6 hours	L12314ES	4kWh	6-12 hours (extended outage coverage)
6-12 hours	MaxPower 8 AIO	8kWh	10-20 hours (whole-home with AC)

FAQs on Lithium IPS Runtime in Bangladesh

Q: Does the runtime decrease over years?
HiTHIUM LiFePO4 batteries lose only ~20% capacity after 11,000 cycles. A 2kWh unit that runs 8 hours when new will still run 6.5+ hours after 10+ years of daily use.

Q: Can I extend runtime by reducing load?
Yes. Switch off heavy loads (AC, microwave, kettle) during outages. A 2kWh unit can run 12+ hours on lights + WiFi + fans + laptop only.

Q: How fast does the IPS recharge?
HiTHIUM units recharge in 4-6 hours from grid. With solar panels (MaxPower 8 AIO has built-in MPPT), recharge is 5-8 hours depending on panel size.

For whole-home backup during multi-hour outages, the HiTHIUM MaxPower 8 (8kWh Residential ESS) handles ACs, fridges, and washing machines with silent LiFePO4 cells rated for 11,000+ cycles.
