Briggs & Stratton SimpliPHI 13.3 kWh Home Battery System
SKU BAS-SIMPLIPHI-13.3-DUAL
The SimpliPHI 13.3 kWh Battery System
The SimpliPHI 13.3 kWh battery system combines two 6.65 kWh modules in a 2-stack configuration, delivering doubled energy storage capacity while maintaining the rapid installation benefits of the RapidStak™ connector system. This configuration provides whole-home backup capability for average residential loads, supporting both essential and non-essential circuits during power outages.
Built with dual lithium ferro phosphate (LFP) modules, this 2-stack configuration provides 10.65 kW of continuous discharge power and 6.66 kW of charge power, making it suitable for comprehensive residential backup power, solar energy storage, and time-of-use optimization. The system maintains full outdoor rating when properly installed, eliminating the need for additional protective enclosures while providing expandability for future energy needs.
SimpliPHI 13.3 kWh Battery System Features
- Whole-Home Power: Dual 6.65 kWh modules deliver 13.3 kWh total capacity with 10.65 kW continuous discharge for comprehensive home backup power.
- Rapid 2-Stack Installation: Complete dual-module system installs in under 5 minutes using RapidStak™ connectors without traditional DC wiring requirements.
- Modular Expandability: Add a third module for 19.95 kWh capacity or expand system-wide to 18 total modules for 119.7 kWh of energy storage.
- Extended Operating Range: Dual modules operate reliably from -20°C to 55°C with full charging capability maintained from -10°C to 50°C.
- Enhanced Safety Design: Dual LFP chemistry modules with individual battery management systems provide redundant safety monitoring and UL 9540A certification.
SimpliPHI's Seamless Inverter Integration
The SimpliPHI 13.3 kWh system integrates seamlessly with Sol-Ark® 8K-2P, 12K-2P, and 15K-2P inverters through full closed-loop communication, providing advanced monitoring and optimization for both modules simultaneously. The system also maintains broad compatibility with any 48V lithium-supporting inverter in non-communicating mode, ensuring flexibility with existing equipment preferences.
SimpliPHI 13.3 kWh Battery System Review
The SimpliPHI 13.3 kWh 2-stack configuration represents an optimal balance between capacity and installation efficiency for standard residential applications. The dual-module design provides sufficient energy storage for whole-home backup scenarios while maintaining the rapid deployment advantages of the RapidStak™ system. The 208 ADC continuous discharge current effectively supports high-draw appliances including electric water heaters, HVAC systems, and multiple simultaneous loads during outages.
The IP65 outdoor rating becomes particularly valuable in 2-stack configurations where the increased capacity justifies dedicated outdoor placement. This weatherproof design allows installation on exterior walls or ground-mounted locations without requiring oversized electrical rooms or garage space for dual modules. The 0.80 C-rate across both modules ensures efficient power delivery while extending cycle life, and the compact vertical footprint maximizes energy density per square foot of installation space.
