Overview

Reliable power when the grid cannot be relied on

30kW Solar System for Off Grid combines solar generation, battery storage and the main system components in one coordinated package. It can keep essential equipment available through outages and reduce routine dependence on diesel generators.

A commercial site can separate priority circuits from optional heavy loads, keeping essential operations running while reducing generator dependence.

How to plan loads around 30kW

Keep these loads running

Lighting, computers, networking, payment and security systems; Commercial refrigeration, water supply and selected cooling circuits

Choose the system around the equipment you want to keep running at the same time during an outage.

Add pumps and comfort loads

Pumps, workshop equipment and larger three-phase loads after starting and phase-balance checks

These loads can be included after we check their running power, starting power and normal operating schedule.

Tell us if you need these too

Electric boilers and heaters, large chillers, welders or heavy production machinery

If you want to run these loads together, tell us before quotation so the inverter, battery and solar array can be sized for them.

Send us the appliance and motor nameplates with your load list. We will check how much equipment can run together and allow for motor or compressor starting power.

Why choose this package

  • Solar panels, inverter, battery and installation components can be reviewed as one system
  • Pure Sine Wave output for common home and business equipment
  • LiFePO4 storage for evening use and grid outages
  • 21.6kWp nominal PV array from 36 pcs × 600 W modules
  • Component specifications are provided to help you review the complete system configuration; components are not sold separately

Before we confirm your quotation

Send the site voltage and phase, appliance or equipment list, daily operating hours, motor starting information and required backup time. We will confirm whether this package fits or recommend a more suitable configuration.

Battery Options Lithium / Gel
Applications Residential / Commercial / Industrial
Mounting Options Roof / Ground

Application Scenarios

Solar Backup for Shops, Clinics & Small Businesses

The system can be sized for essential shop or clinic circuits, such as lighting, refrigeration and point-of-sale equipment.

Solar Power for Farms, Lodges & Remote Sites

Solar generation and battery storage can support priority loads at remote sites. Size the system for pump starting loads and refrigeration hours.

Solar Power for Guesthouses, Lodges & Hotels

Battery backup can keep priority guest services running, such as reception, Wi-Fi and lighting. Size larger loads separately.

Solar Power for Offices & Businesses

Battery backup can support the equipment that keeps work moving, such as computers, network equipment and payment terminals.

Solar Products for Distributors & Installers

The panels, inverter and battery are supplied as a complete package, so installers can assess the configuration together before ordering.
