Overview

Reliable power when the grid cannot be relied on

100kW 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 100kW

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.

System at a glance

  • 1 unit 100kW Three-Phase Solar Inverter
  • 160 pcs 600W Bifacial Dual Glass Solar Panel
  • 1 set 768V 300Ah 241kWh LiFePO4 Battery
  • 1 set Solar Panel Rack
  • 1 set 6mm2 Solar Cable Set

A practical backup example

Consider a 40-room mid-range hotel using about 15,000kWh per month. During an outage, its priority circuit could include reception, WiFi, CCTV and common-area lighting, commercial refrigeration, water pumping, room lights and fans, plus eighteen occupied-room air conditioners, averaging about 22kW while those loads are in use. For this example, we allow 20% for battery reserve and typical system losses, leaving 80% of the 241 kWh nameplate energy available for comparison: 241 kWh × 80% = 192.8kWh; 192.8kWh ÷ 22kW ≈ 8.8 hours. Your actual backup time will depend on the equipment running, battery settings, temperature and installation conditions. Send us your electricity bill or load list and we will calculate the system around your property.

Why we also ask for your load list: Your monthly kWh shows overall energy use, while backup time depends on which appliances you want to keep running together.

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
  • 96kWp nominal PV array from 160 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.

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.

FAQ

What can the 100kW Solar System for Off Grid power?

It can be configured for lighting, computers, networking, payment and security systems; commercial refrigeration, water supply and selected cooling circuits; pumps, workshop equipment and larger three-phase loads after starting and phase-balance checks. Final appliance quantity depends on simultaneous load and motor starting requirements.

How long will the battery last during an outage?

For example, a 40-room mid-range hotel using about 15,000kWh per month, with reception, WiFi, CCTV and common-area lighting, commercial refrigeration, water pumping, room lights and fans, plus eighteen occupied-room air conditioners, could average about 22kW on its priority circuit during an outage. After allowing 20% for reserve and typical system losses, the 241 kWh nameplate battery provides about 192.8kWh for this preliminary comparison—approximately 8.8 hours at the example load. Actual backup time depends on the connected equipment, battery settings and site conditions. Send us your electricity bill or load list for a system recommendation based on your property.

What information is needed for a quotation?

Please provide the site voltage and phase, load list, running hours, pump or compressor starting data, target backup time and available panel installation area.
