Simpliphi PHI 3.8-M Battery 24V or 48V Models

SimpliPhi Power’s PHI 3.8-M TM Battery utilizes the safest Lithium Ion chemistry available, Lithium Ferro Phosphate (LFP). No cobalt or explosive hazards that put customers at risk. By eliminating cobalt, the risk of thermal runaway, fire propagation, operating temperature constraints, and toxic coolants are reduced. When combined with our integrated high-performance Battery Management System (BMS), accessible 80A DC breaker On/Off switch and over-current protection (OCPD), the PHI 3.8-M Battery delivers safe, highly efficient and cost-effective service over the life of both residential and commercial installations, on or off-grid. Compatible with all industry-standard inverter charge controllers, the PHI 3.8-M Battery supports balance-of-system equipment and optimizes any power generation source – solar, wind, grid, generator – with scalable, on-demand energy storage solutions for critical back-up and daily savings on electricity bills.

Simpliphi battery warranty registration can be found HERE. If you do not register the battery, the warranty will not be valid. Please email or give us a call at 866-419-2616 so that we can properly determine the minimum kWh capacity you need for your battery bank. If a problem arises, and SimpliPhi determines that your battery bank was undersized for your system, the warranty will be void and will not be honored. This can be easily avoided by allowing Inverters R US to properly size the battery bank for you.
