Relectrify | Engineered for the best in battery storage

Introducing the AC1

The battery energy storage system that makes every kWh count

250 kW / 1 MWh

Modular inverterless AC battery that is compact, simple and easy to install

20-year performance

Market-leading guarantees on system output

20% more energy

Delivered to your facility over its lifetime

Cell-level control

Optimizing the performance of every battery cell

The AC1 has nearly 4,000 individual battery cells in it. Relectrify monitors and independently controls every single one of them. No other BESS in the world has this level of control. We use to maximize safety, daily performance and asset longevity.

Delivering more energy

Delivering 20% more energy over a 20 year lifetime

Conventional BESS are limited by their weakest battery cells. Because it independently controls every cell, the AC1 delivers dramatically more energy.

40%

It retains 40% more of its original capacity after 20 years of daily cycling.

99%

It reliably delivers 99% of available energy every time it is cycled.

Sophisticated simplicity

AC power without an inverter

The AC1 uses advanced technology to generate grid-compliant AC power directly from the battery cells without an inverter. This means that the AC1 is more compact and less expensive to install and maintain than a conventional BESS.

Adaptive optimization

The world’s only adaptive BMS that gives you full visibility, access and control

Proactive cell-level safety

Cells are continuously monitored for faults and deviations, and any anomalous cell is bypassed without impacting the operation of the battery.

State-of-Charge (SoC) accuracy

We measure SoC with 99% accuracy, so you know exactly how much energy is available at all times to support your facility or bid into the energy market.

Automatic cell balancing

We constantly balance the energy across all cells and packs, ensuring that no energy is stranded, meaning you can always use every kWh of available energy.

Machine-learning algorithms

High frequency granular data is processed via proprietary algorithms to continually adapt, improve, optimize and act.

Real-time State-of-Health

We offer detailed real-time visibility into the health of your system, down to every cell. This helps ensure system uptime and performance.

Performance assured

Service, support and capacity management

Relectrify takes responsibility of the AC1's long-term performance, with local teams providing both remote asset monitoring and preventative maintenance.

And with the advanced technology to support battery pack swapping, the AC1's modularity unlocks new ways to protect and upgrade the long-term capacity of the system.

Plug and play

Installation-ready with reference project designs available and rapid-open standard integration to energy management software platforms

Commercial & Industrial energy users

Energy storage makes sense with the AC1. It unlocks lower project costs and more energy bill savings than any other BESS. Take greater control of your energy future with a business case that works today.

Utility-scale asset owners

Get more from every kWh with the AC1. Its market-leading specs mean that you can install up to 30% less storage to balance your renewable generation assets. Well-suited to smaller MW-scale projects, get the most from storage with the AC1.
