SimpliPhi Power’s AccESS™ with PHI 3.8-M™ batteries and Sol-Ark inverter is a fully integrated and pre-programmed energy storage and management solution. With 15.2kWh of total capacity, the AccESS keeps the lights on and lowers utility bills, creating peace of mind for homeowners and businesses. The AccESS supports a wide variety of applications, and multiple generation sources: Solar, Grid or Generators. Maximize solar 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 and customers installing new, non-retrofitted renewable energy systems can take advantage of integrated MPPT charge controls to create stand-alone or grid-tied systems for whole-home power and generator optimization with auto start capabilities.

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
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.
