AccESS AmpliPHI

The SimpliPhi Power AccESS AmpliPHI system combines (6) AmpliPHI 3.8 kWh lithium ferro phosphate (LFP) batteries with a Sol-Ark 12K hybrid inverter to deliver a fully integrated, pre-programmed energy storage and management solution. Featuring closed-loop communications, it self-monitors, optimizes PV generation, keeps the lights on, and lowers utility bills — providing 24/7 reliable power for homeowners, businesses, and off-grid applications.

With 22.8 kWh total storage capacity and 98% round-trip efficiency, the AccESS AmpliPHI stores excess solar power for critical backup, peak demand shaving, evening self-consumption, and Time-Of-Use cost reduction. It is compatible with grid-tied, off-grid, and hybrid setups, supporting energy arbitrage, generator integration with automatic start, and seamless scalability through the BOSS.6 or BOSS.12 expansion systems.

Built with non-toxic LFP chemistry and no cobalt, the batteries operate without thermal runaway risk, cooling systems, or hazardous materials, delivering unmatched safety, long cycle life, and high performance. The system is outdoor-rated (NEMA 3R) and can be pad-mounted or free-standing, offering flexible installation in residential, commercial, disaster recovery, and military-grade environments.

Standard Features
Internal transfer switch automatically disconnects from the grid during power outages and provides standby power for critical circuits
Outdoor rated enclosure can be free-standing, or pad-mounted
Advanced LFP batteries with a 10,000 cycle / 10-year warranty
98% round trip efficiency
Remote monitoring by web browser or mobile device app
No cobalt , thermal regulation, cooling, or risk of fire
Extended operating temperature
Solar MPPT for DC-coupled or off-grid installations
Automatic Generator control for additional standby power
APPLICATIONS
SIA (Standard Interconnection Agreement) customers: AccESS allows for solar PV power to be stored in batteries for a backup power source, or for self-consumption during evenings or other set times.
NEM (Net Energy Metering) customers: Add energy storage to an existing net-metered solar array for standby power or energy arbitrage purposes.
Off-grid customers: Up to 12 kW Solar MPPT combines power generation and energy management in a single package.
Disaster recovery customers: Reliable, 98% efficient, non-toxic backup power in the event of a power outage.
