Off Grid Solar System

Buyers in off-grid and unstable-grid regions often face the challenge of sourcing solar panels, inverters, batteries, controllers and mounting structures from separate suppliers, only to find they do not work together on site.

The Problem

Why This Is Specified as a Solution

Buyers in off-grid and unstable-grid regions often face the challenge of sourcing solar panels, inverters, batteries, controllers and mounting structures from separate suppliers, only to find they do not work together on site. WeBright Solar provides complete off-grid solar systems from 3KW to 50KW, pre-configured with matched components, including solar panels, inverters, MPPT charge controllers, LiFePO4 or GEL batteries, mounting structures, combiner boxes, cables and MC4 connectors, all packed in wooden boxes for export. The system is tested before shipment so it is ready to commission, not assemble, upon arrival.

Process

Every Stage and What Goes Wrong at It

The amber line is the failure this stage usually produces. The line under it is what we do instead.

1

Enquiry and Load Review

The system is sized based on roof area or a target kW, but the actual appliance load is not known until installation.

We request the list of appliances, their daily running hours and the largest starting load to size the system correctly.

2

System Sizing

Panel output, inverter rating and battery capacity are selected independently, leading to imbalance.

The array size, inverter rating and battery capacity are sized against each other on a single bus voltage to ensure compatibility.

3

Component Selection

Battery type, controller type and panel type are chosen based on price, not on site conditions or system needs.

We define the impact of each choice—such as LiFePO4 vs GEL, MPPT vs PWM—before finalizing the configuration.

4

Mounting Drawings

The mounting structure arrives cut for a flat roof when the building has a pitched tile roof.

Mounting is designed from CAD to match the actual roof or ground condition and confirmed with the buyer before production.

5

Assembly and Testing

A mismatched controller or faulty inverter is discovered only during commissioning.

The inverter and controller are powered up and tested, and the packing list is verified item by item before crating.

6

Packing

Panels, batteries and other components arrive damaged or split across multiple shipments.

Inverter, solar panels, mounting bracket and battery are packed in wooden boxes for export loading in one shipment.

7

Shipping and Documents

The buyer must manage sourcing, consolidation and documentation across multiple suppliers.

OEM, design, sourcing and shipment are handled from one place, so the buyer receives one set of export documents.

8

After Sales

A question during installation has no clear reference, and the system remains idle.

Enquiries are answered within 12 hours over WhatsApp or email, with the configuration table as the shared reference.

Who It Is For

Buyers This Suits

  • Installers who deliver turnkey off-grid systems to remote homes, farms and workshops
  • Importers and wholesalers who resell complete off-grid kits instead of loose components
  • Villa and residential end users who want a power system without sourcing parts separately
  • Contractors installing solar systems in areas with no reliable grid connection
Outcomes

What You End Up With

  • One configuration table that lists every item in the shipment
  • A bus voltage that the panels, controller, inverter and battery already agree on
  • A mounting structure drawn to the actual roof or ground condition
  • One supplier, one shipment and one set of export documents
