Integrated Software Platform
Four Engines.
One Intelligent System.
InterconnectIQ™, EnergiOS™, Coulomb AI™, and GridIQ™ ship pre-installed on every Series-B — no third-party EMS, no integration fees, no separate licensing. Your battery is revenue-ready from day one.
Interconnection is the #1 cause of BESS project delays. InterconnectIQ™ streamlines the entire process — from feeder analysis and substation constraint identification to protection coordination and utility sign-off — reducing timelines from months to weeks.
- Automated feeder analysis and substation constraint identification
- Protection coordination and relay setting recommendations
- Utility application preparation and submission support
- Pre-certified protection schemes for faster sign-off
- Reduces interconnection timelines from months to weeks
The operating system for your energy assets. Monitors, controls, and optimizes every aspect of your battery in real time — from cell-level BMS data to grid tariff signals.
- Real-time energy flow monitoring and control
- Multi-tenant dashboard with per-tenant controls
- Grid tariff integration and rate optimization
- Remote diagnostics and over-the-air updates
- SCADA / Modbus TCP integration ready
The intelligence layer that makes your battery work while you sleep. Continuously evaluates and predicts the optimal energy scenario — every 15 minutes, 24/7 — to maximize payments and savings.
- Predictive load forecasting and price signal analysis
- Automated arbitrage — charge low, discharge high
- Demand charge reduction scheduling
- Grid services dispatch optimization
- VPP aggregation and dispatch coordination
Your direct connection to grid revenue markets. Handles enrollment, dispatch, and settlement for all available grid services programs — turning your battery into a revenue-generating DER.
- Demand Response (DR) program enrollment and dispatch
- Capacity market participation and bidding
- Frequency regulation (FFR / PFR) response
- Virtual Power Plant (VPP) aggregation
- Automated settlement and revenue reporting
Mobile App & Tenant Portal
Full Visibility.
Complete Control.
The EnergiOS™ mobile app gives property owners, operators, and individual tenants real-time visibility into energy flows, battery status, and revenue earned — all from a single intuitive dashboard. Give each tenant on your property their own access to optimize their utility bill independently.
- Live battery SOC, power flow, grid status, and solar generation in one view
- See exactly how much your system has earned from arbitrage, DR, and grid services
- Per-tenant access — each business on your property controls their own energy optimization
- Push notifications for system events, maintenance reminders, and performance anomalies
Revenue Streams
Four Ways Your Battery Pays You Back
The Series-B doesn't just store energy — it actively generates revenue and reduces costs across four independent income streams, simultaneously optimized by Coulomb AI™.
Charge during off-peak low-rate hours. Discharge during peak high-rate hours. Coulomb AI™ automates this 24/7 to maximize rate spread capture.
Eliminate peak demand charges — often the largest line item on a commercial utility bill — by discharging during peak consumption windows.
Get paid by the grid operator for providing demand response, capacity market participation, and frequency regulation through GridIQ™.
Enroll in a VPP aggregation program and earn revenue by allowing the grid operator to dispatch your battery as part of a coordinated DER fleet.
Technical Specifications
Built to Spec. Engineered to Last.
The Series-B is designed for 20-year commercial deployments. Every specification is engineered for real-world conditions — not laboratory ideals. Air-cooled operation across extreme temperature ranges means no HVAC infrastructure and no moving parts to maintain.

Applications
Where the Series-B Performs
Peak Demand & Arbitrage
Eliminate demand charges and capture rate spread arbitrage at manufacturing facilities, big-box retail, data centers, and multi-tenant commercial properties.
Mission-Critical Backup Power
Replace diesel generators and traditional UPS with a zero-maintenance sodium-ion system — no thermal runaway risk, no HVAC, compliant with domestic supply chain requirements.
Renewable Integration
Pair with solar to maximize self-consumption, eliminate export curtailment, and participate in grid services programs — all managed autonomously by GridIQ™.
Campus Microgrids & OEM Integration
Deploy multiple Series-B units in parallel for campus-scale microgrids, or integrate as the battery core in OEM and EPC custom BESS builds — universities, hospitals, and industrial parks.
