AC-coupled retrofit
Connects on the AC side to expand storage without intervening on the DC bus of the existing PV system.
REFERENCE C&I BESS ARCHITECTURE
Atmoce M-ELV BattBank · 1.568 kWh / 980 kVA

What this architecture delivers
Distributed conversion
Each module provides 16 kWh and 10 kVA; capacity and power grow in stages.
Extra-low voltage per module
M-ELV architecture with DC voltage below 60 V per module, LFP chemistry and IP66 protection.
Tower-based scaling
The reference arranges seven modules per tower to form 14 sets of 112 kWh and 70 kVA.
Reference configuration
Indicative breakdown of the system shown. Final references, protection and accessories are validated against the single-line diagram and real project data.

This is a commercial and technical reference, not a closed BOM for purchasing or construction. The final BOQ may vary because of grid, regulations, protection, cabling, EMS, communications, works and engineering requirements.
Before finalising the BOM
We need to validate the following data to turn this reference into an executable quotation.
Hourly or 15-minute load curve and contracted power.
Single-line diagram, voltage, phases, transformer and point of connection.
Operating goal: self-consumption, peak shaving, backup or microgrid.
Available space, clearances, access and environmental conditions.
Critical loads, autonomy, starting peaks and control strategy.
Frequently asked questions
Is this bill of materials final?
No. It is the reference configuration that explains the stated capacity and power. The final list is validated against the single-line diagram, grid, load profile and current documentation.
Does it include switchgear, protection, cabling and commissioning?
Only items explicitly listed are considered included. Switchgear, protection, cabling, communications, works, transport and commissioning are defined in the final proposal.
Can power or capacity be adjusted?
Yes, where the architecture and manufacturer range permit. Every change requires recalculating blocks, conversion, control, protection and operating conditions.
