Tesla Solar Inverter (3.8kW to 7.6kW)
SKU TESLA-INV-1538000-XX-Y
The Tesla Solar Inverter brings Tesla's renowned power electronics expertise to residential solar installations, offering four scalable models from 3.8kW to 7.6kW. Built on proven Powerwall technology, this string inverter achieves 98.6% peak efficiency and 98.0% CEC efficiency while featuring four independent MPPT channels for enhanced design flexibility.
The inverter includes revenue-grade metering with ±0.5% accuracy for Solar Renewable Energy Credit (SREC) programs, integrated arc fault circuit interrupter (AFCI), and rapid shutdown compliance. Four MPPT channels with flexible input connectors (1-2-1-2 configuration) support multiple roof planes and shading tolerance without requiring module-level power electronics.
Tesla Inverter Features
- Proven Power Electronics Platform: Built on Powerwall technology with 98.6% peak efficiency, delivering exceptional reliability and performance.
- 4 Independent MPPT Channels: Maximum design flexibility with 60-480 VDC range per MPPT supporting multiple roof planes, orientations, and shading conditions.
- Native Powerwall Integration: Seamless compatibility with Tesla Powerwall systems enables unified energy management, backup power coordination, and whole-home optimization.
- Tesla App Ecosystem: Real-time monitoring, energy consumption tracking, and system management through intuitive mobile interface.
- Low Voltage Operation Capability: 60VDC minimum operating voltage enables shorter string configurations and accommodates installations with fewer modules per string.
Monitor with The Tesla App
For homeowners, Tesla Solar Inverter completes the Tesla ecosystem via unified management through a single mobile app. The Tesla App provides real-time monitoring and control of solar production, Powerwall storage, vehicle charging, and home energy consumption with automatic system optimization for cost savings and efficiency.
Tesla Inverter Technical Review
The Tesla inverter's string-level architecture deliberately avoids module-level power electronics while maintaining MPPT granularity through its four-channel design. Maximum 13A per MPPT with 17A short circuit current capability accommodates modern high-power solar modules without current limiting concerns. Integrated AFCI and rapid shutdown compliance streamlines NEC 2017/2020 conformance without external components or additional failure points.
The comprehensive connectivity suite—Wi-Fi, Ethernet, and cellular LTE/4G—provides redundancy for monitoring and over-the-air updates, critical for maintaining system performance throughout the 12.5-year warranty period. Native Tesla App integration delivers exceptional value for customers invested in the Tesla ecosystem
