Got a shaded roof, mixed panel types, or an irregular layout? The APSystems QS1 microinverter was designed exactly for that.
Unlike traditional string inverters, the QS1 operates at the module level — meaning shade on one panel doesn't drag down your whole array. Each panel operates independently, so your system stays closer to peak output even when conditions aren't perfect.
Key highlights: ☀️ Panel-level MPPT for superior shade tolerance 📊 Real-time monitoring via APSystems' Enlighten platform ⚡ Rapid shutdown compatible for code compliance 🔧 Scalable design — expand your array without a full inverter overhaul 🛡️ Structured warranty with authorized service support
Whether you're a homeowner with trees casting shadows or a contractor building a repeatable install stack, QS1 delivers the flexibility and visibility that string inverters simply can't match.
