Product Overview

What This Product Is

A 20KW grid-tie solar power system for homes with reliable grid access. It includes up to 60 pieces of 450W mono solar panels, two 10KW 3-phase grid-tie inverters, dual MPPT controllers, a 2-input 1-output combiner box with switches, breaker and SPD, mounting structure, 200 meters of 4mm2 and 6mm2 PV cable, 30 pairs of MC4 connectors, and a tool bag with installation tools. The system is designed to feed surplus power back to the grid via net metering, reducing electricity bills without requiring battery storage.

Key Benefits

What You Get

  • Reduces electricity bills by feeding surplus solar power back to the grid through net metering
  • Uses the utility grid as a virtual battery with no maintenance or replacement costs
  • No need for battery storage, simplifying system design and lowering upfront cost
  • Two 10KW 3-phase inverters provide redundancy and scalable power handling
  • Dual MPPT controllers allow independent tracking of two panel strings for maximum yield
  • Combiner box with SPD, switches and breaker included to prevent overvoltage and short circuits
Who It Is For

Buyers and Sites

  • Homeowners seeking to lower electricity bills with grid-tied solar
  • Solar installers supplying complete grid-tie systems with minimal on-site configuration
  • EPC contractors managing residential solar projects with standardised system designs
  • Importers and wholesalers supplying grid-tie systems to markets with net metering policies
  • Residential end users who want a system that works with the grid instead of replacing it
Application Scenarios

Where It Is Installed

  • Homes with stable grid access that want to reduce electricity bills through net metering
  • Homes where battery storage is not needed and grid export is allowed by local utility
  • Properties with high daytime electricity use and surplus generation during peak sun hours
  • New builds or retrofits where a complete, pre-configured solar system is preferred over component sourcing

Manufacturing and Preparation

Before It Ships

  • Review the home’s daily load and grid connection capacity to confirm 20KW system suitability
  • Design panel layout and string configuration to match the 350V-850V input range of the MPPT controllers
  • Select mounting structure type based on roof pitch, flat roof, soil or cement ground
  • Assemble the system with panels, combiner box, inverters, cables and connectors before packing
  • Test inverter and controller communication and DC input readiness before shipment
Quality Control

Checked Before Packing

Customisation

What Can Be Changed at Order Stage

  • Change panel type between mono and poly, blue or black, 330W to 560W
  • Switch inverter output from single phase to three phase, EU or US standard
  • Modify mounting structure with CAD drawings for pitched roof, flat roof, soil or cement ground
  • Replace standard cable with longer length or different gauge if required
Comparison

How It Compares With the Alternatives

Off-grid solar systemNo battery bank needed, but cannot operate during grid outage
Hybrid solar systemLower cost and simpler, but cannot store energy for use when the grid is down
Buying components separatelyPre-matched voltage and current ratings reduce on-site compatibility issues
Diesel generatorNo fuel cost or noise, but only works when the grid is available
Use Guide

Getting It Working on Site

1

Confirm the grid connection can accept 20KW of export power before installation

2

Connect the two panel strings to the dual MPPT inputs to maximise yield

3

Land the combiner box output to the inverter input with proper grounding and SPD bonding

4

Verify inverter communication and grid sync before energising the system

FAQ

Questions About the Residential Solar Power System 20KW Grid-tie PV Solar Energy System for Home Use

What is the purpose of a 20KW grid-tie system?

It generates solar power for home use and feeds surplus electricity back to the grid, reducing electricity bills through net metering.

Does the kit include the battery?

No. This is a grid-tie system, so it does not include a battery bank. It relies on the grid as a virtual battery.

What is included in the tool bag?

The tool bag contains an MC4 spanner, crimping pliers, and a wire stripper for PV cable and connector installation.

Are the inverters single phase or three phase?

The inverters are 3-phase, suitable for residential and commercial applications with three-phase grid access.

How is the system packed for shipping?

The inverter, solar panels, mounting bracket, and other components are packed in wooden boxes for export loading.

Can the mounting structure be customised for my roof?

Yes. The mounting structure is customised based on CAD drawings for pitched roof, flat roof, soil, or cement ground installation.
