How EMS makes battery storage go further

Our conversations with customers lately have revealed that iwell's offerings address three major unmet needs for installers: EMS technology that makes hardware smarter, modelling services that demonstrate battery savings and revenues, and clear communication of achievable battery performance to EPCs and partners. This blog addresses the first point: how EMS improves battery storage systems.

What EMS actually does

An energy management system is the brain behind the battery. It monitors energy flows in real time, responds to market dynamics and makes autonomous decisions that maximise immediate savings and long-term asset performance.

Specifically, an intelligent EMS handles:

• Multiple value streams simultaneously. Peak shaving, frequency response, backup power and solar self-consumption are optimisation opportunities. The EMS decides which to prioritise based on real-time conditions and forecasted returns.
• Adaptation to changes in energy prices and grid conditions. An EMS adjusts automatically, charging when electricity is cheap and discharging when it's valuable, without manual intervention.
• Load forecasting. By predicting consumption patterns and energy prices, the EMS positions the battery to deliver maximum value before demand even hits.
• Battery health optimisation. The EMS manages depth of discharge, charging rates and operational patterns to extend battery life while still capturing revenue opportunities.

Hardware and intelligence work better together

Battery storage hardware does what it's designed to do: store energy reliably and efficiently. That said, the real performance gains come when you pair that hardware with intelligent control.

When you pair hardware with intelligent EMS, you're offering a system that:

• Delivers measurable ROI from day one.
• Adapts to changing tariffs and grid conditions.
• Provides visibility into asset performance through customer portals
  Creates confidence in battery performance claims.

Think of it this way: EMS strategizes your hardware’s capacity. When the two work together, you unlock capabilities that neither can deliver alone, like optimised charge cycles, revenue stacking, grid responsiveness and extended asset life. 

Currently, our EMS is offered as an add-on to hardware installations. Due to growing demand, we’re preparing to launch a standalone EMS in early 2026. That will make it possible to integrate with existing battery systems and open new opportunities for installers working across mixed hardware environments.

Ready to optimise your battery storage systems?

A battery stores energy while an EMS decides what to do with it. For installers building a business around energy storage, that distinction is everything. Offering energy intelligence will give your installation business a competitive advantage.
