How much does a hybrid inverter cost in Sri Lanka in 2026?

As an indicative guide as of July 2026, EAST single-phase hybrid inverters start around Rs 350,000 for a 6 kW unit, and three-phase models run from roughly Rs 560,000 (10 kW) to Rs 640,000 (20 kW) for the inverter SKU alone, before VAT. Batteries, solar panels and installation are quoted separately because they depend on your loads and site.

What does a complete solar and battery system cost in Sri Lanka?

As of July 2026, complete MyEnergy packages including inverter, LiFePO4 battery, panels and standard installation run from about Rs 1.2 million for a 6 kW backup starter system (10 kWh, no panels) to Rs 1.6–1.9 million for 6 kW solar systems with 8–10 panels, Rs 2.7–3.7 million for whole-home single-phase systems, and Rs 3.8–8 million for three-phase systems for larger homes and businesses.

What size hybrid inverter do I need?

Match the inverter to your peak load and the solar and battery you plan to run, not just your bill. Single-phase homes usually land between 5 and 12 kW; three-phase homes and businesses between 10 and 20 kW. Our build-my-system tool gives a starting point and a consultant confirms it.

Single-phase or three-phase?

If your incoming supply is single-phase, you need a single-phase hybrid inverter; if it is three-phase, you need a three-phase one. Larger homes, villas and businesses are typically three-phase. Check your main breaker or ask your electricity bill category.

Do hybrid inverter prices include installation?

Inverter SKU prices are for the unit alone, ex-VAT. Installation involves mounting, DC and AC protection, cabling, earthing, changeover wiring for backup circuits and commissioning, and is quoted with the full system. MyEnergy packages combine equipment and standard installation into one price.

Is a cheaper inverter worth it?

A hybrid inverter runs every day for years and controls an expensive battery. A well-built, battery-ready, IP-rated unit with proper protection and monitoring is worth more over its life than a bare budget inverter that limits your storage or fails early.

Hybrid Inverter Price in Sri Lanka (2026): Sizes, Types & What to Pay

July 16, 2026

If you are shopping for a hybrid inverter in Sri Lanka, the first thing to know is that the inverter is only part of the price. It is the brain of a solar-plus-storage system, but the battery, panels and installation are usually the larger numbers. This guide sets out realistic 2026 inverter prices, what a complete installed system costs, how to size one, and what actually matters when you compare quotes.

What a hybrid inverter does

A hybrid inverter does three jobs that an ordinary grid-tied (string) inverter cannot. It converts your solar DC into usable AC power, like any inverter. It charges and manages a battery — from your panels during the day, or from the grid during cheap off-peak hours. And when the grid fails, it disconnects and keeps your essential circuits running from the battery automatically, typically fast enough that you barely notice the cut.

That third job is the one that matters most in Sri Lanka. A plain solar inverter shuts down during a power cut for safety, panels or not. A hybrid inverter with a battery is what actually keeps the lights on — and it is the piece that decides, hour by hour, whether your home runs on sun, stored energy or the grid. That decision-making is exactly how you beat a time-of-use tariff: solar by day, battery through the expensive evening peak, grid only when it is cheap.

2026 price guide (inverter SKU only, ex-VAT)

Indicative figures for the EAST range we supply, as of July 2026 — the inverter unit only, before VAT, delivery and installation:

Single-phase, 6 kW (EAHI-6000-SL) — from around Rs 350,000.
Single-phase, 10–12 kW (EAHI-10-12KSL) — from around Rs 660,000.
Three-phase, 10 kW (EAHI10KTH) — from around Rs 560,000.
Three-phase, 15 kW (EAHI15KTH) — from around Rs 610,000.
Three-phase, 20 kW (EAHI20KTH) — from around Rs 640,000.

These are inverter-only figures. Batteries, solar panels, cabling and installation are quoted separately because they vary so much by site, and prices move with exchange rates and stock — so treat them as a planning guide, not a quotation. See the full range on the hybrid inverters page.

What drives the price

Four things separate a Rs 350,000 inverter from a Rs 660,000 one. Capacity — the continuous kW it can deliver, which sets how many loads run at once and how much solar it can manage. Phase — three-phase electronics cost more than single-phase at the same rating. Battery architecture — higher-capacity three-phase units work with high-voltage (750 V class) battery stacks, which changes the power electronics. And build quality — an IP66-rated enclosure that can live outdoors, full protection (anti-islanding, surge, over/under-voltage) and proper app monitoring all cost real money in the box. When two quotes look far apart, the difference is usually one of these four, not margin.

Inverter price vs total system cost

The inverter is typically only 15–25% of a complete system. For context, our packaged systems — inverter, LiFePO4 battery, panels where included, and standard installation, priced as one — currently run roughly as follows (July 2026, indicative):

Backup starter (6 kW, 10 kWh, no panels) — around Rs 1.2 million.
Solar essential (6 kW, 10 kWh, 8 panels) — around Rs 1.6 million.
Solar plus (6 kW, 16 kWh, 10 panels) — around Rs 1.9 million.
Whole-home single-phase (10–12 kW, 16–32 kWh, 18–20 panels) — around Rs 2.7–3.7 million.
Three-phase systems (10–15 kW, 15–41 kWh, 18–35 panels) — around Rs 3.8–8 million.

Seeing the whole-system number first protects you from a common trap: choosing an inverter that looks cheap but locks you out of the battery capacity you will actually want. Browse the packages to see how the pieces price together.

How to size the inverter

Size to your peak load and the solar and storage you want to run, not just your monthly bill. Two worked examples:

A typical single-phase home — lights, fans, fridge, TV, a couple of ACs used in the evening, monthly bill in the mid tens of thousands of rupees. Peak simultaneous load is usually 3–5 kW, so a 6 kW hybrid inverter carries the house comfortably and leaves headroom for a 10–16 kWh battery and 8–10 panels. This is the most common system we install.

A large three-phase home or small business — multiple ACs, a pump, kitchen equipment, loads spread across three phases. Here 10–15 kW three-phase units are the right band, paired with high-voltage stacked storage that can grow to 60 kWh per cluster.

Oversizing wastes money; undersizing limits how much solar and battery you can add later — and the battery is where the daily savings live. The quickest way to get a sensible number is our build-my-system tool, which works from your actual CEB bill; a consultant then confirms it against your real loads at the site survey.

Single-phase vs three-phase

This is set by your supply, not by preference. If your premises is fed single-phase, you need a single-phase inverter; if three-phase, a three-phase one. Larger homes, villas, hotels and factories are usually three-phase. Check your main incoming breaker — a single-pole main is single-phase, a three-pole main is three-phase — or your CEB tariff category. Our guide to single-phase vs three-phase systems covers this in detail, and we confirm it on every site visit.

The all-in-one alternative

Instead of buying an inverter and a separate battery, you can use an all-in-one energy storage system that integrates both in one floor-standing enclosure. The inverter module alone runs around Rs 628,000 (10 kW) to Rs 718,000 (20 kW), with 5 kWh battery modules stacking underneath as you need them. It is cleaner on the wall, faster to install, and expanding later means literally stacking another module. For many homes it is the simplest route to solar-plus-storage, and it is how our ME ONE systems are built.

What actually matters when you compare

Look past the sticker price at six things. Battery compatibility and expansion headroom — can the inverter take the storage you will want in three years, not just today? Backup transfer — does it switch fast enough that computers and routers stay up? PV input headroom — can it accept more panels than you start with? IP rating — IP66 can be mounted outside; lesser units need a sheltered wall. Protection — surge, anti-islanding, over/under-voltage, and certification to the standards your utility connection requires. Monitoring and support — a proper app, and an installer who will still answer the phone in year five. A hybrid inverter cycles every day for years and manages a battery worth more than itself; a robust, battery-ready unit earns its price back.

The running-cost angle most buyers miss

An inverter quote is a one-time number, but the reason to buy is a recurring one: every unit of expensive evening-peak grid power you replace with your own solar or stored energy. On an applicable time-of-use tariff, the battery the inverter manages shifts your consumption out of the peak band every single day — which is why pairing the right inverter with enough storage matters more than shaving a few percent off the inverter price. We cover the tariff mechanics in how to beat the 2026 CEB tariff hikes with solar and battery.

Build your system to see inverter, battery and solar priced together for your home or business — it takes about two minutes from your CEB bill.
