Sunways Inverter- South Asia

16/09/2026

Residential roofs are rarely one clean, unshaded surface. Different orientations, partial shade and unequal roof areas can force installers to place PV strings with different operating conditions into the same design.

That is where MPPT flexibility becomes practical—not just technical.

Across the Sunways three-phase low-voltage hybrid inverter series, the MPPT operating window is 160–850 V, which means can generate power in very early morning.

For the installer and system designer, this can mean:
- more freedom to separate arrays with different orientations or irradiance conditions
- less compromise when making use of several available roof sections
- a clearer string layout for larger or more complex residential and light-commercial projects
- one inverter range that can cover both simpler and more demanding roof designs

The value is not “more MPPTs” by itself. The value is having more ways to design around the actual roof instead of forcing the roof to fit the inverter.

How many roof orientations do you typically deal with on residential projects?

After the shift from NEM to ATAP in Malaysia, many projects are still designed the "old way". And that's exactly why ROI becomes slower. From what we've seen in recent projects, designing under ATAP requires a different approach:

1️⃣ Maximize Daytime Consumption
The more solar energy you use directly, the higher your savings.
Exporting to grid (SMP) gives much lower returns.
👉 Systems should match daytime load, not just roof size.
2️⃣ Avoid Oversizing the System
Bigger is NOT always better under ATAP.
Oversized systems = more energy exported = lower ROI
👉 Right sizing is more important than maximum capacity.
3️⃣ Consider Hybrid-Ready Setup
Even if battery is not installed now, having a hybrid-ready inverter gives flexibility for the future.
👉 Especially when night consumption is high
4️⃣ Think in Terms of Energy Flow, Not Just Equipment
Solar design today is no longer just about panels and inverters.
👉 It's about how energy is generated, used, stored, and optimized

In short:
Under ATAP, a well-designed smaller system can outperform a larger poorly designed one. We've been helping clients adjust their system design based on this logic, and the difference in ROI is very clear.

If you are working on projects in Malaysia, happy to share some suggestions.
