Solar Inverter Price in Bangladesh (2026)
The inverter is the brain of a solar system — it converts panel output into usable electricity and, in hybrid systems, manages your battery. In a new installation it's included in the package price; as a replacement, a like-for-like unit typically costs BDT 40,000–60,000 around year 12–15 of system life.
This guide covers how inverter pricing works in Bangladesh, the cost differences between types, how to size one correctly, and what to check before you pay for an upgrade or replacement.
What does a solar inverter cost in Bangladesh?
| Buying situation | Typical cost | Notes |
|---|---|---|
| New system (included) | Part of the package — e.g. 5kW hybrid systems from BDT 275,000 | Grid-tied, hybrid or off-grid inverter sized to your array |
| Like-for-like replacement | BDT 40,000–60,000 | Typical around year 12–15; budget this as a running cost |
| Upgrade (e.g. adding battery support) | Cost of new inverter minus resale/trade of the old one | Usually done together with a battery addition |
These are estimates for planning — your exact price depends on capacity, type, brand tier and installation details. A site survey gives you a fixed quote.
What drives the price
- Capacity — a 10kW inverter costs substantially more than a 3kW unit
- Type — grid-tied units are the cheapest; hybrid inverters cost more but manage batteries; off-grid units sit at the top
- Topology — string inverters are cheapest; micro-inverters add 15–20% but give per-panel optimisation
- Brand tier — premium brands with longer warranties and better monitoring cost more upfront and last longer
- Features — dual MPPT inputs, remote monitoring, higher surge ratings and grid-support functions
- Phase and protections — three-phase units and full DC/AC protection add cost
Grid-tied, hybrid or off-grid?
Grid-tied is the cheapest path and delivers the fastest payback — ideal if you simply want to cut your bill and export surplus under net metering. Hybrid adds battery management: it costs more but keeps essential loads running through load-shedding. Read more about adding storage on the solar battery price guide.
Off-grid suits sites with no reliable grid connection and is sized around nightly load, not roof size. Compare typical packages on the 5kW and 10kW system pages.
Sizing and lifespan: what to budget
Match the inverter to your array — a 5kW array means a 5–6kW inverter. Slight oversizing is normal (it handles heat and future additions better); grossly oversized units cost more and run inefficiently. Plan for one replacement in the system's lifetime: a like-for-like swap around year 12–15 for roughly BDT 40,000–60,000 at today's prices.
When it's time, choose an installer who stocks spares and services what they sell — the failure patterns we see in older systems are mostly quality and after-sales problems, not technology problems.
What to check before you pay
- Written warranty terms (years, and what's covered — board, fan, firmware)
- Monitoring included and working after commissioning
- Correct grid-protection settings for BPDB requirements
- Compatibility with your existing panels and any planned battery
- Earthing and surge protection inspected at the same visit
Frequently asked questions
How much does a solar inverter cost in Bangladesh?
In a new system, the inverter is included in the package — 5kW hybrid systems start around BDT 275,000 fully installed. For replacements, like-for-like units typically run BDT 40,000–60,000 based on our replacement data around year 12–15. Exact pricing depends on capacity, type and brand tier.
How long does a solar inverter last?
A quality inverter typically works for 12–15 years. After that, a replacement is a normal running cost — we budget around BDT 40,000–60,000 for a like-for-like swap at today's prices.
What's the difference between grid-tied, hybrid and off-grid inverters?
Grid-tied inverters only work with the grid and offer the fastest payback. Hybrid inverters also charge and manage batteries, so they keep working during outages. Off-grid inverters run entirely on solar and battery, with no grid connection at all.
How do I size an inverter for my system?
The inverter should broadly match your array — a 5kW array means a 5–6kW inverter. Your installer confirms the exact figure based on panel layout, load profile and whether you plan to add battery storage later.
String or micro-inverter — which is better?
String inverters are the cheapest and most common option. Micro-inverters add 15–20% to the cost but give per-panel optimisation, which helps on shaded or complex roofs. Most Bangladeshi homes are fine with a quality string or hybrid inverter.
