Turn Energy into an Asset
Slash Demand Charges
Automate peak-shaving to flatten utility spikes. Our system predicts demand surges and discharges automatically, lowering operational costs
Full-scenario functionality
Peak/off-peak arbitrage, demand charge control, virtual power plant, backup power, black start — one system handles it all.
Easy installation
All-in-one design cuts delivery time, simplifies installation, and gets you connected to the grid sooner, so returns start earlier.
Higher Lifecycle Returns
Built to last longer. Our double-loop liquid cooling maintains temp differences ≤3∘C, extending battery life to over 8,000 cycles for 20% higher lifetime returns
Proactive safe design
Protection starts at the cell. Thermal isolation, multi-layer safeguards, and centralized monitoring stack up through every module, cluster, and cabinet.
Zero Thermal Runaway Risk
Protect your facility with the industry’s safest battery. We utilize "Full-Link" safety with AI prediction that detects risks 15 minutes before they occur, backed by a record of 0 thermal runaway incidents across 12GWh deployed.
Hi-MO One Pro
Quick to Install.
Built to Scale.
Zero On-Site Debugging
Cut delivery cycles by 40%. The eEMS comes factory-preset with European grid parameters (VDE, G99), allowing you to install and commission without complex on-site coding.
"1+11" Infinite Scalability
Standardize your inventory. The PotisFlexi system allows you to connect up to 11 battery cabinets to a single PCS unit, scaling from 2-hour to 24-hour backup configurations easily.
No Civil Engineering Required (All-in-One Design)
Drop it anywhere. With IP55 protection and pre-integrated fire suppression/cooling, you don't need to build dedicated battery rooms or containment structures.
Slash O&M Costs (Remote Diagnosis)
Reduce truck rolls by 60%. Our cloud-based diagnosis allows you to identify module-level faults remotely, and the modular design allows for quick swap-outs.
Eliminate Cabling Risks (iCCS Technology)
We replaced the "Spaghetti wiring" harnesses with rigid iCCS boards, reducing connection points by 80% and eliminating the most common failure point in installations.
Full European Compliance Support (CoE)
We do the paperwork with you. Our European Center of Excellence (CoE) assists with load analysis, grid connection applications, and provides local training certification.
