Solar Inverter Singapore: Types, Price & How to Choose

[Updated, August 2026]

Key Takeaways:
A solar inverter converts your panels' DC output into usable AC power your home can runt on. On-grid inverters are standard for Singapore homes, with a standalone replacement typically costing S$800–S$8,000 depending on capacity. GetSolar's Rent-to-Own plans fold the inverter, installation, and maintenance into one fixed monthly payment.

Solar panels alone can't power your home. Without the right inverter, they generate electricity your lights and appliances can't actually use.

Most homeowners will research panels first and treat the inverter as an afterthought. Your inverter's type, size, and price directly affect how much you save and how reliable your system is day to day.

This guide breaks down what a solar inverter does, the types available for a solar inverter for home use in Singapore, what one actually costs, and how to pick the right one.

What Does a Solar Inverter Do?

Solar panels generate electricity as direct current (DC), but your home runs on alternating current (AC). A solar inverter converts DC to AC, making the energy usable for your lights, air-con, and appliances.

It also manages how energy flows between your solar system, your home, and the power grid. It monitors performance, improves safety, and enables features like exporting excess electricity.

Whether combination of panels and solar inverter you land on, the inverter is what determines how much of that generation you actually get to use.

A solar inverter is what turns your panels from roof decoration into a working power system.

Types of Solar Inverters in Singapore

There are a few key types of solar inverters, each suited to different home setups, budgets, and energy goals.

On-Grid Inverter (Most Common in Singapore)

On-grid inverters, also known as grid-tied inverters, are the standard choice for most homes. These systems connect to both your solar panels and the national power grid. During the day, solar powers your home directly. At night, the system automatically draws electricity from the grid.

The benefit here is you can export unused solar energy to the grid and earn credits through metering schemes. This setup suits homes looking to reduce electricity bills without battery storage.

At GetSolar, we use the Huawei SUN2000 inverter, which offers up to 98.6% efficiency and includes smart monitoring features.

Off-Grid Inverter

Off-grid inverters come with integrated battery storage, and are designed to store excess energy during the day to be used at night or during power outages.

While offering full energy independence, they're rarely used due to the Singapore’s stable grid and the high cost of battery storage. Off-grid systems are more suited for remote areas with unreliable grid access.

Hybrid Inverter

Hybrid inverters combine battery storage with grid connection, so you can store excess solar power for later use while still staying connected to the grid as backup. The main benefit is being able to draw on stored energy during peak electricity pricing hours or power outages, while still keeping the grid as a fallback.

However, hybrid inverters are generally not recommended in Singapore,, as the added battery cost makes them more expensive than standard on-grid systems. They're growing in popularity among larger homes and commercial setups, though, as they provide future readiness for EV charging or greater energy independence.

If you're weighing whether that extra cost is worth it, our solar battery guide for Singapore breaks down the full cost-benefit case.

Smart Inverter

Smart inverters communicate directly with the power grid in real time and respond to changes in voltage or demand. Many models include AI-powered diagnostics, smart home integration, and mobile app monitoring.

In Singapore, smart inverters are increasingly popular among homeowners who want advanced control, automation, and real-time performance tracking from their solar system.

String Inverters vs Microinverters

Beyond inverter type, you'll also decide how your panels connect to the inverter: in a string setup, or individually through microinverters.

String inverters are the most cost-effective and common setup in Singapore. One central inverter connects multiple panels. This works well for rooftops with even sunlight exposure, but if one panel is shaded or underperforms, it affects the entire system's output.

Microinverters are installed on each panel individually. They optimise performance panel by panel, making them ideal for rooftops with shading or mixed orientations. They cost more but deliver higher output and panel-level monitoring, which is especially useful on complex roofs.

How Solar Inverters Are Installed in Singapore Homes

In Singapore, inverters are usually wall-mounted in a shaded, ventilated area, often near the attic or ground-floor distribution box (DB). DC cables from your solar panels route to the inverter, where the electricity converts to AC and flows into your DB to power your home.

If your system produces more energy than you use, the excess exports automatically back to the grid. Under Singapore's metering schemes, you'll receive credits for this, reducing your electricity bill.

Installing the inverter closer to the panels reduces cable loss and maximises efficiency.

How Much Does a Solar Inverter Cost in Singapore?

A solar inverter is usually bundled into your total system quote alongside panels, mounting, and labour. As a standalone purchase, a solar inverter in Singapore typically costs S$800 to S$8,000, depending on system capacity, inverter type, and brand.

Most inverters come with a 5-year warranty. Extending that coverage typically adds S$300 to S$800.

Under GetSolar's Rent-to-Own plans, the inverter, installation, and ongoing maintenance are folded into one fixed monthly payment, so you don’t have to worry about getting it separately later.

How To Choose The Right Inverter For Your Home

Your solar installer will usually recommend the most suitable inverter for your system, but understanding the key factors yourself helps you make a more informed choice.

Start with system size compatibility. Your inverter's capacity should match or slightly exceed your solar panel system's total output. This prevents inverter clipping, where the inverter can't convert all the power your panels generate. Based on your expected energy usage, your installer may recommend a slightly smaller inverter to optimise cost.

Next, look at inverter efficiency. Most good models range from 95% to 99%, with some power lost during conversion. For better performance, choose an inverter with MPPT (Maximum Power Point Tracking). MPPT continuously adjusts to changing sunlight conditions like cloud cover or partial shading to extract the most energy possible from your panels.

The type of electrical supply in your home matters too. If you're on a single-phase power supply, common in Singapore homes, you might need multiple smaller inverters instead of one large one. This avoids overloading the grid and keeps energy flow safe. Homes with three-phase supply can generally handle larger systems with fewer devices.

Monitoring features matter as well. Many modern inverters connect to mobile apps or online platforms that track performance in real time. Huawei's FusionSolar app, for example, provides live data and alerts you to issues like panel shading or faults.

Check the warranty and expected lifespan too. Most inverters last 10 to 12 years, with warranties ranging from 5 to 12 years depending on the brand. Our solar panel warranty guide breaks down the difference between product and performance warranties, which applies to inverters too.

If you're aiming to maximise your solar panel output, look into how your inverter setup handles shading or panel orientation. For homes using a string inverter, shading on one panel can affect the whole string's performance. In these cases, power optimisers let individual panels perform independently — a cost-effective way to reduce output loss in partially shaded conditions. You can explore more strategies in our guide to solar panel installation costs in Singapore.

Common Issues and Inverter Maintenance

Solar inverters are generally reliable, but they can run into issues if not installed or maintained properly.

Overheating is a common problem that usually happens when the inverter sits in direct sunlight or an area with poor airflow. Dust and loose wiring increase the risk too. If you notice signs of overheating, switch off non-essential appliances and contact your installer. The best prevention is placing the inverter in a shaded, well-ventilated space, ideally indoors or under an overhang.

Another potential issue is an isolation fault, which happens when the insulation between the inverter's internal circuits and the grid breaks down. This can cause system shutdowns and requires professional repair.

Importantly, DIY installation or repair isn't allowed in Singapore. All solar systems, including the inverter, must be installed and commissioned by SP-certified electricians. This keeps your system safe, compliant, and properly connected to the grid. Trying to fix an issue yourself could be dangerous and void your warranty.

If you're worried about long-term care, many homeowners prefer a solar setup that includes professional maintenance and system checks. That's why Rent-to-Own plans include full servicing and performance guarantees, so you can enjoy your solar savings without the stress.

The Inverter Decides How Much Solar You Actually Get

A solar inverter serves as the heart of your solar system. It's what turns sunlight into usable electricity and keeps everything running smoothly. Choosing the right type, at the right price, helps you maximise performance, minimise issues, and get the most from your solar investment.
