In Dhaka, the capital of Bangladesh, a real but often overlooked market is rapidly expanding—hidden electricity anxiety among residents of high‑density urban apartments. There are no large rooftops and no opportunity to install photovoltaics, yet power outages are frequent, especially during hot summer periods when demand for basic electricity becomes more rigid.
Many assume the future of new energy must belong to photovoltaics, but in urban environments like Dhaka the reality follows a different logic: no rooftop means no PV, and no PV means reliance on a grid plus storage combination.
1. An overlooked market of urgent urban electricity needs
Customer inquiries reveal a typical household load profile:
2–3 ceiling fans (essential in high heat)
10–15 light bulbs (basic lighting)
1 refrigerator (food preservation)
Total load about 1–2 kW, with the core need being simple—maintain basic life for 1–2 hours during an outage.
This demand is common in Dhaka. Many residents live in high‑rise apartments where:
Rooftops belong to landlords or property management and cannot be used for PV
Balconies are small and lack sufficient sunlight
Grid supply is unreliable with frequent outages
A clear market conclusion emerges:
Urban users do not need complex PV systems; they need plug‑and‑play backup power (IPS systems).
2. IPS systems: the optimal solution for urban apartments
IPS, Instant Power Supply, is essentially:
Grid charging + outage switching + battery supply
It is not a replacement for PV systems but an alternative adapted to urban environments.
Core features include:
Normally charging from mains
Automatic switching during outage
Support for basic household appliances
Low cost, simple installation, no house modification required
For cities like Dhaka, IPS systems can be more practical than PV.
3. ONESUN MSF series: energy storage designed for cities
ONESUN, a global leader in energy storage solutions, offers flexible product lines. The MSF series is tailored for this market.
1) Urban apartment version (PV‑free)
Designed for cities like Dhaka:
Mains‑only charging
Built‑in lithium battery storage
Plug‑and‑play, no installation required
Supports 1–2 kW load for 1–2 hours
This matches the core customer need—low‑cost relief from outage anxiety.
2) Rural distributed version (with PV)
For rural or low‑density areas:
Can connect to PV panels
Achieves off‑grid power
Suitable for areas with no or weak grid
ONESUN covers both urban and rural energy scenarios with one product family.
4. Why choose ONESUN?
Despite fierce global competition, ONESUN continues to win overseas customers due to its comprehensive strengths:
1. Technical reliability
Core team from leading industry companies, automotive‑grade design principles ensure system stability and safety.
2. Complete product line
From telecom station batteries to integrated energy storage systems and the MSF series, it covers diverse applications.
3. Flexible OEM/ODM capability
Can quickly customize solutions for different national markets such as urban apartments in Dhaka.
4. Cost and performance balance
Controls system cost while meeting basic needs, suitable for developing country markets.
5. Similar markets beyond Bangladesh
This “high‑density + weak grid + no PV” market exists in other countries:
India (high‑density apartments in Mumbai, Delhi)
Pakistan (severe power shortages in Karachi)
Nigeria (high population density in Lagos)
Philippines (unstable urban grids)
These markets share:
High population density + unreliable power + constrained PV installation
This indicates a large blue‑ocean market where IPS energy storage products will be a core entry.
6. Conclusion: the real opportunity is where PV cannot be installed
PV changed the global energy landscape over the past decade, but in the next decade storage will solve last‑mile electricity problems.
In cities like Dhaka, people do not need complex systems; they need:
Lights to stay on during outages
Fans to keep running
Refrigerators to keep working
This is what the ONESUN MSF series addresses.
Not every household can adopt PV, but every household needs power.
For B2B customers, this is not only a product opportunity but a large market entry point.
If you are looking for urban energy storage solutions or want to enter emerging markets like Bangladesh, ONESUN is a worthwhile long‑term partner.
