How it works

Store, smooth, shift, and discharge through one controlled loop.

ARYION connects solar, grid, storage, generator, and critical loads into a managed power loop that can prioritize cost savings, uptime, or renewable utilization.

wb_sunny

Solar Generation

Solar panels convert sunlight into clean DC power during the daytime to meet the immediate energy needs of your facility.

bolt

Immediate Consumption

A grid-tied inverter converts the DC solar energy into AC electricity, powering household or facility loads in real-time.

sync_alt

Net Metering & Export

Any excess solar power not consumed immediately is exported back to the utility grid, generating credits and lowering net energy bills.

electrical_services

Grid-Charged Backup

The high-capacity battery system is charged from the utility grid during off-peak hours when power is cheaper and readily available.

offline_bolt

Instant Outage Transition

Upon a grid blackout, the battery system takes over the load instantly (under 10-20ms) to ensure continuous, zero-interruption operations.

battery_charging_full

Stored Energy Discharge

Critical loads such as common area lighting, lifts, water pumps, and servers run entirely on quiet, exhaust-free battery power.

hub

Dynamic Power Routing

Integrates solar panels, battery, and utility grid into one controlled loop, dynamically choosing the most cost-effective power source.

trending_down

Peak Load Shaving

Discharges the batteries during peak rate hours to avoid high grid tariffs, and recharges them using daytime solar or low-cost off-peak grid power.

shield

Complete Energy Resilience

Ensures uninterrupted runtime during outages by utilizing solar power to run loads and charge batteries, keeping you fully powered for days.
