Briggs & Stratton SimpliPHI 19.95 kWh Home Battery System
SKU BAS-SIMPLIPHI-19.95-TRIPLE
The SimpliPHI 19.95 kWh Battery System
The SimpliPHI 19.95 kWh battery system combines three 6.65 kWh modules in a maximum 3-stack configuration, delivering comprehensive energy storage capacity for larger residential installations. This configuration provides extended backup duration for whole-home power while supporting high-demand electrical loads including electric vehicle charging, pool equipment, and workshop machinery.
Built with triple lithium ferro phosphate (LFP) modules, this 3-stack configuration provides 13.98 kW of continuous discharge power and 9.98 kW of charge power, making it suitable for comprehensive backup power, solar energy storage, and time-of-use optimization for larger energy consumers. The system maintains full outdoor rating when properly installed, eliminating the need for additional protective enclosures while maximizing energy density in a compact vertical footprint.
SimpliPHI 19.95 kWh Battery System Features
- Maximum Stack Capacity: Three 6.65 kWh modules deliver 19.95 kWh total capacity with 13.98 kW continuous discharge for extended whole-home backup power.
- High-Power Applications: 273 ADC continuous current and 17.5 kW surge capability supports electric vehicle charging, pool equipment, and high-demand appliances.
- Maximum Stack Installation: Complete 3-module system installs in under 5 minutes using RapidStakā¢ connectors in the maximum allowable stack configuration.
- System Scalability: Multiple 3-stacks can be combined for up to 18 total modules system-wide, achieving 119.7 kWh of total energy storage.
- Triple Module Management: Individual battery management systems in each module provide comprehensive monitoring and safety control across all three units.
SimpliPHI's Seamless Inverter Integration
The SimpliPHI 19.95 kWh system integrates seamlessly with Sol-ArkĀ® 8K-2P, 12K-2P, and 15K-2P inverters through full closed-loop communication, providing advanced monitoring and optimization across all three 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 19.95 kWh Battery System Review
The SimpliPHI 19.95 kWh 3-stack configuration represents the maximum single-stack capacity in the SimpliPHI platform. The triple-module design delivers substantial backup duration for whole-home scenarios while supporting high-demand applications like electric vehicle charging and workshop equipment. The 273 ADC continuous discharge current provides exceptional power delivery capability, effectively managing multiple high-draw loads simultaneously during extended outages.
The IP65 outdoor rating proves essential for 3-stack installations where the increased physical footprint and weight (375 lbs) make outdoor placement preferable to indoor installations. The weatherproof design allows ground-mounting or wall-mounting without requiring structural modifications to accommodate triple-module weight in interior spaces. The 0.70 C-rate across the three modules optimizes power delivery while maintaining long-term cycle life, and the compact 60.4" vertical height maximizes energy density while minimizing ground footprint.
