Product Overview

What This Product Is

A 3KW off-grid solar kit for a small home with no reliable grid connection. It ships as a matched set: 6 pieces of 350W poly or mono solar modules, a 24V 80A MPPT or PWM charge controller, a 2KW 24Vdc off-grid inverter, a 4-piece 12V 200Ah or 250Ah GEL or AGM battery bank, with the combiner box, mounting structure, cable, connectors and tool bag already included. The battery voltage, controller and inverter are chosen to work together, so the installer commissions the system instead of proving compatibility on site.

Key Benefits

What You Get

  • Runs a small home entirely on solar energy with no grid connection required
  • Panel string voltage matched to the 24Vdc inverter and controller before shipment
  • Battery bank sized at 4 pieces of 12V 200Ah or 250Ah so capacity is adjustable at order stage
  • Combiner box with switches, breaker and SPD supplied instead of sourced separately
  • 200 meters of 4mm2 and 6mm2 PV cable and 5 pairs of MC4 connectors in the same shipment
  • Installation tool bag with MC4 spanner, crimping pliers and wire stripper included
Who It Is For

Buyers and Sites

  • Solar installers building complete residential systems from one delivery
  • Importers and wholesalers supplying off-grid households in unstable-grid markets
  • Small families and couples with average household power use
  • Homeowners in small houses who want a battery-backed supply rather than panels alone
Application Scenarios

Where It Is Installed

  • Detached houses in remote areas with no utility connection at all
  • Small family homes on a weak rural feeder with frequent outages
  • Holiday houses and farm dwellings that need power without a diesel generator
  • Replacement of a generator-only supply where fuel delivery is unreliable
Problems It Solves

What This Removes From the Job

Quality Control

Checked Before Packing

Customisation

What Can Be Changed at Order Stage

  • Battery capacity changed between 200Ah and 250Ah or switched to lithium
  • Charge controller changed between MPPT and PWM
  • Module type changed between mono, poly and PERC in blue or black
  • Mounting structure drawn to the roof or ground condition with CAD drawings
  • Inverter output set for single phase or three phase EU or US standard
Comparison

How It Compares With the Alternatives

Grid-tie solar systemWorks with no grid present, but needs a battery bank that a grid-tie system does not
Solar hybrid energy systemSimpler and cheaper, but cannot fall back to the grid when the battery is low
Buying panels, inverter and battery separatelyFixed configuration and less freedom on brands, in exchange for a bus voltage that already matches
Diesel generatorNo fuel logistics and no running noise, but the battery bank is replaced after around 15 years
Use Guide

Getting It Working on Site

1

Size the daily load first, then confirm the 2KW inverter covers the largest starting load

2

Mount the array so all 6 modules share the same orientation and shading condition

3

Land the array on the combiner box before the controller, keeping the SPD earth bonded

4

Bring the battery bank to a matched state of charge before first commissioning

5

Keep the battery room ventilated and check bank voltage on a regular schedule
