Solar Retail Network: Three Portals, Unified Inventory

How we built and connected a multi-brand renewable energy e-commerce cluster (BuySolars, BuyBattery, BuyInverter) to synchronize heavy equipment stock, freight calculation, and quotation workflows from one control panel.

The challenge

Operating specialized retail verticals for solar panels, industrial inverters, and tubular/lithium batteries created fragmented operations. Updating prices for volatile dollar-rate solar hardware across three standalone websites was error-prone, while standard courier plugins failed to calculate heavy cargo freight rates accurately for out-of-city consignments.

  • Volatile Forex Price Fluctuations: Solar hardware prices fluctuated weekly with foreign exchange rates, forcing staff to update hundreds of SKUs manually across three separate stores.
  • Heavy Freight Undercharging Discrepancies: Standard e-commerce courier plugins only handled small parcels, resulting in massive shipping losses on 60kg+ tubular batteries and palletized solar panels.
  • Disconnected B2B Quotation Workflows: Solar EPC contractors demanded formal commercial quotations before purchasing, requiring manual calculation and PDF formatting that slowed sales cycles.
Unified Multi-Store E-Commerce Engine

What we built

A centralized commerce architecture linking three consumer portals directly into a unified catalog, logistics, and quotation backend.

🔄 Centralized Master Catalog Sync

Single management cockpit where modifying a tier price, specification sheet, or warehouse stock level instantly propagates across BuySolars, BuyBattery, and BuyInverter.

🚚 Heavy Freight Matrix Engine

Proprietary shipping rate engine calculating pallet weights, volumetric constraints, and regional city hubs to charge precise logistics rates on heavy consignments.

📄 Instant EPC Quotation Generator

Automated B2B bid generator enabling commercial installers to configure system sizes, select inverters, and download formal branded PDF quotes with warranty terms in seconds.

💳 Localized Industrial Payment Flows

Integrated checkout supporting direct bank IBAN transfers, split deposits for cargo dispatch security, and automated WhatsApp shipment tracking updates.

The result

A streamlined multi-channel retail operation that cut catalog update maintenance hours drastically while eliminating freight undercharging on heavy battery dispatches.

3 Stores

Catalog administration time reduced by 65%; multi-store inventory stockout errors reduced to zero across all three retail portals.

Technical Stack & Architecture

Multi-storehead architecture, central inventory API, custom logistics calculation algorithms, automated PDF generation.
