Overview

Start with the loads that matter during an outage: refrigeration, lighting, communications, water pumping or other agreed circuits. From there, the RFQ can bring together PV modules, a hybrid inverter, battery storage, roof hardware and protection equipment. The local installer or EPC still owns the final electrical design, grid approval, protection settings and installation work.

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

Common Challenges

Most homeowners do not need every appliance backed up. The hard part is agreeing which circuits must stay on and how long they need to run.
Installers need one coherent equipment request rather than separate module, inverter, battery and mounting decisions that may not fit together.
Roof condition, battery pairing, grid settings and destination documents are all project checks; they cannot be confirmed from a package name.

Our Approach

Begin with an essential-load list, site phase, roof area and the period those loads must be supported. Roof area alone is not a sizing method.

Ask for one equipment schedule covering PV, inverter, battery, mounting and protection. The local installer then validates wiring, earthing, protection and permits.

If later battery expansion is important, confirm the exact inverter, BMS and battery platform before treating expansion as an option.

Key Benefits

Defined backup scope
A practical critical-load list avoids presenting an oversized whole-home backup package as the default.
Matched procurement
One BOM can align the equipment interfaces and packing plan before the installer starts work.
Expandable where suitable
Battery expansion can be considered after the final platform, BMS, and load profile are confirmed.

Typical Configuration

Rooftop PV modules
N-type or monocrystalline modules selected for available roof area and mounting layout.
Hybrid inverter
Single- or three-phase platform selected against the local supply and essential-load requirement.
LFP battery storage
Modular low- or high-voltage storage matched to the approved inverter battery interface.
Backup distribution
Separate distribution arrangement for priority circuits, finalized by the local electrical contractor.
Roof mounting and BOS
Racking, cable, isolators, surge protection, connectors, and labels specified to the project scope.

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.

Essential-load schedule
List each circuit, running watts, starting demand, operating hours and required outage duration; separate essential from discretionary loads.
Electrical and roof conditions
Share phase and voltage, existing distribution, roof type and usable area, shading, equipment location and installation environment.
Backup and battery objective
State whether the priority is outage continuity, self-consumption or both, plus any future expansion requirement.
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

Confirm the exact battery model, BMS protocol, and destination grid code before quotation approval.
Battery transport documents, manuals, and packing details are confirmed for the selected equipment.

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.
