Replace your EMS. Keep your project running.
When your EMS or PPC underperforms, Fractal EMS retrofits it in place — a proven, low-risk process to swap in hardware-agnostic controls, stronger cybersecurity, and real support.
The EMS is your project's operating system — responsible for controls (charging and discharging), optimization (revenue and health), and safety (electrical and fire), coordinating the inverters, BMS, breakers, and fire system. When it doesn't work well, owners increasingly choose to retrofit rather than live with the consequences. Retrofitting is a big decision, and the sequence matters — which is exactly what our process is built around.
~20%
of Fractal's deal flow is EMS retrofits — replacing an underperforming or unsupported system with Fractal EMS.
— Daniel Crotzer, CEO
Why owners retrofit
Underperformance
Stratified SOCs, unreadable or unclearable fault codes, BMS deficiencies, poor DC-coupled PV+storage, and missed ancillary qualifications like Fast Frequency Response.
Cost
The EMS subscription runs over 1% of annual revenue, or is simply expensive relative to the features it delivers.
Downtime & support
Availability under 99%, an integrator that has maxed out its liquidated damages, offshored or poor technical support, or a vendor that has gone insolvent.
Cybersecurity & domestic risk
Gaps against NERC CIP, NIST 800-53, and ISO 27001; cyber risk from a foreign BMS; CFIUS concerns; offshored development; or the need for on-site controls with no cloud commands.
Software & integration
Lackluster HMI, historian, analytics, or reporting; no fire-system integration; or an EMS that won't integrate cleanly with the owner's SCADA.
Fleet consolidation
As owners accumulate projects, they standardize on one universal EMS — while keeping the freedom to choose different equipment project to project.
