Energy Storage Products
Zevonexa supplies configurable energy storage systems for commercial, industrial and remote-power applications. Choose a product family below or send us your site data for a tailored configuration.
C&I BESS
Commercial and industrial battery storage for peak shaving, backup, load management and renewable-energy integration.
Solar + BESS
Integrated storage architecture for higher PV utilization, smoother output and extended clean-energy availability.
Diesel + BESS
Hybrid systems designed to reduce inefficient generator operation, fuel consumption and cycling.
Microgrid & Backup Power
Storage-centered power systems for weak-grid, off-grid and remote civilian facilities.
Select a BESS by operating objective
| Objective | Relevant system | Critical inputs |
|---|---|---|
| Peak shaving and tariff control | C&I BESS | Interval load data, peak target and tariff windows |
| Higher solar self-consumption | Solar + BESS | PV profile, daytime load and grid export limits |
| Fuel reduction at remote sites | Diesel + BESS | Genset ratings, minimum loading and duty cycle |
| Weak-grid, off-grid or resilience | Microgrid & Backup | Critical load, autonomy and source-transition logic |
Reference capacities such as a 215kWh BESS or 1MWh battery energy storage system are useful starting points, but final selection must reconcile kW, usable kWh, C-rate, expected cycles, temperature, redundancy, grid requirements and control strategy. Read our commercial BESS sizing guide before issuing an RFQ.
Typical system scope
Power and storage
- Battery racks, modules or integrated cabinets
- PCS matched to grid-connected or hybrid operation
- Transformer and switchgear coordination where required
Control and protection
- BMS, EMS and site communication architecture
- Thermal management and fire-protection configuration
- Remote monitoring, alarms and operational data
Frequently asked questions
Is a 215kWh BESS suitable for every commercial site?
No. Suitability depends on peak power, required duration, usable capacity, daily cycling, grid conditions and the application objective. The load profile should be reviewed before selecting a cabinet size.
What data is needed for a BESS quotation?
Provide project location, application, load curve, required power and energy, PV and generator capacities, grid condition, backup duration, environmental conditions and project schedule.
Can Zevonexa support EPCs and system integrators?
Yes. We support project-based equipment supply, configuration discussions and technical-commercial documentation for legitimate civilian commercial and industrial projects.
Need a project-specific configuration?
Send your load profile, PV or generator capacity, required backup duration, grid condition and project location.
Which BESS configuration should you start with?
| Starting point | Typical use | Key sizing inputs |
|---|---|---|
| 215kWh BESS | Modular C&I storage, peak shaving, solar self-consumption, backup | Load profile, peak kW, backup duration, PV size |
| 1MWh BESS | Larger industrial, mining, solar-diesel and EPC projects | Interval load data, PCS power, grid or generator plant, duty cycle |
| Microgrid & Backup | Weak-grid, off-grid and critical-load applications | Critical loads, outage profile, generator/PV resources, control logic |
These are starting points, not fixed designs. Final BESS selection should reconcile power, usable energy, operating objective, redundancy, environmental conditions and the project interconnection boundary.
Define the operating duty before selecting equipment
A commercial battery energy storage system should be specified around the site operating objective, not only a nominal kWh figure. Two projects with the same energy capacity may require different PCS power, C-rate, usable depth of discharge, thermal design, protection coordination and EMS logic. A clear duty statement reduces quotation gaps and makes bids easier to compare.
1. Power duty
Confirm continuous kW, short-duration peak demand, motor-start requirements, grid-forming or grid-following operation and any overload duty expected from the PCS.
2. Usable energy
Define required discharge duration, usable state-of-charge window, reserve margin, expected degradation and whether capacity must remain available for backup events.
3. Integration boundary
Clarify whether the supply scope includes battery cabinets or containers, PCS, transformer, switchgear, EMS, monitoring, communications, commissioning support and documentation.
4. Site conditions
Provide ambient temperature, altitude, humidity, dust or corrosion exposure, installation space, grid voltage and frequency, local standards and delivery constraints.
Information required for a comparable BESS quotation
For EPCs and industrial buyers, the fastest route to a technically comparable proposal is a structured RFQ. At minimum, include the items below. Where interval data is not yet available, provide the best verified estimates and identify assumptions that still require site confirmation.
- Project country, installation environment and target delivery schedule.
- 15-minute or hourly load profile, peak demand and critical-load list.
- Required PCS power in kW or MW and usable energy in kWh or MWh.
- PV array, diesel-generator and grid capacities, including operating schedules.
- Primary objective: peak shaving, solar shifting, fuel reduction, backup, weak-grid support or off-grid operation.
- Required autonomy, daily cycles, reserve margin and expected project life.
- Connection voltage, communication protocol, EMS responsibility and interconnection boundary.
- Certification, testing, documentation, packaging and commissioning requirements.
Use the BESS sizing calculator for an initial screening estimate, review the 500kW/1MWh sizing example, or send the complete inputs through our RFQ form for engineering review.
