VLM Commercial ESS (METISSEES) delivers turnkey battery energy storage systems (BESS), photovoltaic arrays, hybrid inverters, EMS/BMS, and PCS solutions. Our portfolio includes compact storage cabinets, containerised 1 MWh+ systems, and integrated microgrid controllers. We enable peak shaving, load shifting, islanding, and black‑start – reducing energy costs and carbon footprint for commercial and industrial clients.
Scalable battery storage, solar PV, hybrid inverters, EMS/BMS, PCS, and microgrid controllers – engineered for factories, offices, hospitals, schools, and critical infrastructure.
Modular battery containers from 500 kWh to 10 MWh, with integrated PCS, fire suppression, HVAC, and EMS. Ideal for factories, logistics hubs, and industrial parks.
On‑site solar and battery storage for factories and production lines – reduce grid dependency, shave peak demand, and lower energy costs.
Energy storage for commercial office towers – reduce demand charges, participate in demand response, and provide backup for critical loads.
Combined solar and battery systems for large‑scale manufacturing – maximise self‑consumption, reduce OPEX, and ensure production continuity.
Integrated storage for shopping malls, mixed‑use developments, and office parks – with EV charging and renewable self‑consumption.
Advanced energy management and microgrid control software – optimise dispatch, integrate renewables, and enable grid services.
Mission‑critical UPS and battery backup for operating theatres, ICUs, and data centres – zero transfer time and multi‑day autonomy.
Educational institution PV + storage – reduce bills, provide learning opportunities, and ensure backup for labs and admin.
High‑reliability uninterruptible power for data centres, telecom, and financial institutions – N+1 redundancy and extended runtime.
Compact, integrated storage cabinets from 100 kWh to 500 kWh – ideal for office buildings, retail, and small factories for peak shaving and backup.
Leverage time‑of‑use pricing and grid incentives – our systems automatically charge during off‑peak and discharge during peak hours, maximising savings.
Comprehensive audit and retrofit services – upgrade legacy systems with modern storage, PV, and intelligent controls to cut energy waste.
Real‑world installations across factories, offices, healthcare, and education – each tailored to specific operational and environmental challenges.
2 MWh BESS + 1.5 MWp solar – peak shaving, backup, and grid services for a multi‑tenant manufacturing zone.
500 kWh storage cabinet with EMS – reducing demand charges and participating in frequency regulation for a 20‑storey commercial building.
1 MWh UPS with N+1 redundancy – zero transfer time for ICUs and operating theatres, with multi‑day autonomy.
200 kWp rooftop PV + 150 kWh battery – powering labs and admin, with educational dashboard for students.
800 kWh storage + EV charging – peak shaving and demand response for a large shopping mall.
2 MVA modular UPS with lithium‑ion – ensuring 99.999% availability for a Tier‑IV data centre.
VLM Commercial ESS (branded as METISSEES) designs, supplies, and operates advanced battery energy storage systems, photovoltaic solar plants, hybrid inverters, EMS/BMS, and PCS solutions. Our engineering centres are located in Paris (France) and Houston (USA), with regional support offices in Singapore and Dubai.
