Solar Backup for Shops, Clinics & Small Businesses
Keep Priority Business Loads Working Through Outages

Solar Backup for Shops, Clinics & Small Businesses

Design solar and battery backup around the equipment that protects revenue, stock, customer service and security. We size from your actual business hours, bills, outage pattern and equipment—not from a generic “small business” package.

Solar Power for Farms, Lodges & Remote Sites
Design Around Water, Cold Storage, Guests and Remote Operations

Solar Power for Farms, Lodges & Remote Sites

Plan solar and battery power for the loads that keep a remote site operating: pumps, refrigeration, communications, lighting, security and guest or staff services. We separate farm production loads from lodge loads before selecting equipment.

Solar Power for Guesthouses, Lodges & Hotels
Solar & Battery Power for Hospitality

Solar Power for Guesthouses, Lodges & Hotels

Design solar and battery storage around your room count, local grid, generator use and day-to-night load profile. Keep priority guest services available through outages while reducing generator hours and night-time noise.

Solar Power for Offices & Businesses
Keep Teams, Networks and Customer Service Online

Solar Power for Offices & Businesses

Design solar and battery backup around the work that cannot stop: computers, networks, payment systems, communications, security and selected cooling. Use real operating hours and equipment demand to protect productivity through outages.

Solar Products for Distributors & Installers
Build a Solar Range Your Customers Can Actually Use

Solar Products for Distributors & Installers

Plan a sellable product mix around the homes, shops, farms, hospitality sites and commercial projects in your market—not a container of disconnected components. We help match inverters, batteries, panels and balance-of-system products for quotation and stocking.

Overview

Reliable power when the grid cannot be relied on

50kW 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 50kW

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 50kW Growatt Three-Phase Solar Inverter
  • 80 pcs 600W Bifacial Dual Glass Solar Panel
  • 1 set 512V 314Ah 160kWh LiFePO4 Battery
  • 1 set Solar Panel Rack
  • 1 set 6mm2 Solar Cable Set
  • 1 pcs PC10-360V PV Combiner Box

A practical backup example

Consider a 25-room mid-range hotel using about 8,000kWh per month. During an outage, its priority circuit could include reception, WiFi, CCTV and corridor lighting, refrigeration, water pumping, room lights and fans, plus ten occupied-room air conditioners, averaging about 12kW while those loads are in use. For this example, we allow 20% for battery reserve and typical system losses, leaving 80% of the 160 kWh nameplate energy available for comparison: 160 kWh × 80% = 128kWh; 128kWh ÷ 12kW ≈ 10.7 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
  • 48kWp nominal PV array from 80 pcs × 600 W modules
  • Individual linked components remain visible for specification, replacement and repeat-order review

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.

FAQ

What can the 50kW 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 25-room mid-range hotel using about 8,000kWh per month, with reception, WiFi, CCTV and corridor lighting, refrigeration, water pumping, room lights and fans, plus ten occupied-room air conditioners, could average about 12kW on its priority circuit during an outage. After allowing 20% for reserve and typical system losses, the 160 kWh nameplate battery provides about 128kWh for this preliminary comparison—approximately 10.7 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.
