Overview

At commercial sites with variable loads, the storage question is not simply how many kWh to buy. The team must first agree whether the project is addressing continuity, generator operation, daytime PV use, peak demand or a combination of these. This page turns those decisions into a controlled request for PV, power conversion, battery, controls and protection equipment, while leaving final controls, protection coordination, fire-safety design and commissioning with the appointed EPC or integrator.

Illustrative equipment context for Commercial Solar + Storage Hybrid — Illustrative equipment context only. The final BOM, interfaces, protection and installation arrangement must be confirmed for the actual project.

Common Challenges

Factories and cold-chain sites often have changing production loads and an existing diesel generator.
A battery cannot be sized responsibly as a percentage of PV capacity without the operating objective and load profile.
Supplier, EPC and owner roles for equipment, controls, installation and commissioning must be recorded in one scope.

Our Approach

Review load timing, peaks, motor starts, generator characteristics and the intended role of storage before selecting a platform.

Let the project design decide between AC- and DC-coupled routes, with the required control and protection interfaces documented.

Issue one supply schedule that states included equipment as well as local engineering and commissioning exclusions.

Key Benefits

Objective-led sizing
The package can be built around daytime offset, continuity, generator reduction, or peak management rather than a generic ratio.
Clear delivery boundary
Supply scope and local engineering responsibilities are stated before shipment.
Scalable platform review
PV and storage expansion options can be assessed against the final architecture and site constraints.

Typical Configuration

PV generation
Module and string-inverter blocks sized to the daytime energy target and site layout.
Commercial LFP storage
Rack or containerized storage with BMS and thermal-management scope confirmed for the final platform.
Hybrid inverter / PCS
Power conversion equipment selected for voltage, load, backup mode, and approved battery compatibility.
Metering and controls interfaces
Interfaces required for monitoring, generator coordination, and the EPC's energy-management design.

What we need for a useful RFQ

This is a practical guide, not a submission gate. Share the available project context first and we can clarify the remaining inputs together.

Start with the Solar Load CalculatorOrganize daily kWh, simultaneous peak and critical backup loads before equipment review.

Interval load and operating objective
Provide interval data where available, peak and motor-start demand, critical loads, operating hours and whether storage is for continuity, PV shifting, generator support or peak management.
Grid and generator behaviour
Confirm supply voltage, outage pattern, generator rating and controls, export requirements, tariff constraints and proposed AC- or DC-coupled architecture if already designed.
System interfaces and site safety
Share the single-line status, PCS and battery boundaries, EMS requirements, equipment location, ambient conditions, fire strategy, protection and commissioning responsibility.
Destination and document requirements
Provide the country, delivery point, grid or permit requirements already identified, requested documents, quantity and target date.

Procurement and delivery notes

Send interval load data and generator details where available; these matter more than a simple annual energy estimate.
Battery transport, fire-safety scope, HVAC, and local compliance requirements are confirmed per final equipment model and site.

Relevant product platforms

These are independent product research routes, not a validated system bundle. Confirm the exact model, electrical architecture, protocol compatibility, documents, inclusions and project requirements before an order is released.
