At Circuit Solar, we’re excited to offer the DS3 Series microinverters—a high-performance, dual-module inverter line from APsystems that delivers exceptional efficiency, safety, and flexibility. Whether you’re installing a small rooftop system or a large multi-array setup, DS3 microinverters make it easy to maximize energy output with modern solar modules.
What Makes DS3 Microinverters Stand Out?
The DS3 Series is engineered for today’s high-wattage panels, offering one of the highest power densities in the industry. With three models—DS3-S, DS3-L, and DS3-H—these microinverters are ideal for dual-module installations where space, shading, and panel mismatch are common challenges.
Each DS3 microinverter supports two solar panels with independent MPPT tracking, allowing you to harvest the most energy possible—even when panels face different orientations or partial shading occurs.
Built for Canadian Weather & Compliance
APsystems DS3 microinverters are CSA and UL certified, and feature an IP67-rated enclosure for full weather protection. Designed for climates ranging from -40°C to 65°C, they’re well suited for residential installations from BC to Newfoundland.
They also support rapid shutdown compliance when paired with the APsystems ECU-R gateway—making them safe and code-compliant for Canadian installations under CSA C22.2 and NEC 2020 guidelines.
Backed by a 25-Year Warranty for Long-Term Peace of Mind
When you choose DS3 microinverters from APsystems, you’re investing in technology that’s built to last. Each unit is backed by an industry-leading 25-year warranty, providing long-term reliability and confidence for both installers and homeowners.
This extended warranty reflects APsystems’ commitment to quality, durability, and long-term performance. Whether you’re deploying a system in a cold Canadian climate or a sun-drenched rooftop, the DS3’s rugged design and proven track record ensure it will deliver consistent energy output for decades to come.
At Circuit Solar, we only stock inverters that meet our high standards—and the DS3 series exceeds them. With a full 25 years of coverage, it’s one of the most future-proof microinverter options available on the market today.
Powerful Options for Every Rooftop
The DS3 line includes three models to support various panel wattages and project sizes:
- DS3-S (640W AC output): Best for 300–400W panels
- DS3-L (768W AC output): Great for 400–505W panels
- DS3-H (960W AC output): Perfect for high-efficiency 600–730W modules
All models support two modules per unit, helping reduce installation time, hardware costs, and inverter clutter on the roof.
Smart Monitoring & System Optimization
The DS3 series features Zigbee wireless communication, enabling real-time performance tracking through the APsystems EMA app when used with the ECU-R. This gives installers and homeowners visibility into every module—helping quickly identify underperformance, shading issues, or system errors.
