Reduced Energy Bills

Smart storage lowers energy costs without changing how you operate.

Besst AIO stores energy when it’s cheapest and releases it when you need it most – helping businesses reduce peak demand charges and optimize overall consumption. With intelligent energy scheduling, savings become automatic.

Tax & Grid Incentive Ready

Take full advantage of support schemes and rebates.

Besst is designed to comply with regional energy programs, making your business eligible for subsidies, tax benefits, or grid balancing incentives. Our team helps configure your setup to maximize your returns.

Resilience & Backup Power

Stay online during grid outages with built-in backup.

Besst AIO acts as a silent energy safety net for your critical operations. In the event of a blackout, the system automatically takes over to keep lights, equipment, or servers running without interruption.

Data Visibility & Smart Control

Know exactly where your energy goes – and how to optimize it.

Through the Besst app and dashboard, businesses gain real-time insights into storage levels, usage trends, and cost performance. Track your CO₂ impact, set smart schedules, and control key loads remotely.

Shared Infrastructure

Power multiple tenants, units, or spaces with one system.

Besst’s flexible installation model supports shared access across co-working spaces, apartment blocks, or multi-unit sites. It helps reduce infrastructure costs while giving each user reliable energy access.
