2025 Briggs & Stratton AccESS™ with AmpliPHI™ Batteries and Sol-Ark®

AccESS™ with AmpliPHI™ Batteries and Sol-Ark® Inverter

AccESS™ with AmpliPHI™ 3.8kWh batteries and Sol-Ark Inverter is a fully integrated and pre-programmed energy storage and management solution with closed-loop communications that self-monitors, keeps the lights on and lowers utility bills, creating peace of mind for homeowners and businesses. AccESS maximizes PV generation by storing excess power for critical backup, evening hours and daily self-consumption to offset Time-Of-Use rates. Net-metered customers can add energy storage to existing grid-tied solar systems for standby power or energy arbitrage. Off-grid customers can take advantage of integrated MPPT charge controls to create stand-alone systems for whole-home power and generator optimization with auto start capabilities.
