Overview

Reliable power when the grid cannot be relied on

11kW 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 villa or small office can prioritise refrigeration, lighting, communications, security and water supply during an outage.

How to plan loads around 11kW

Keep these loads running

Lighting, fans, TVs, WiFi and computers; Refrigerators, freezers, CCTV and POS equipment

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

Add pumps and comfort loads

A water pump or selected air-conditioning circuits after starting power is confirmed

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 water heating, electric cooking, several air conditioners or large workshop tools

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 11kW Split Phase Solar Inverter
  • 12 pcs 600W Bifacial Dual Glass Solar Panel
  • 1 set 51.2V 350Ah Lithium Battery
  • 1 set Solar Panel Rack
  • 1 set 4mm2 Solar Cable Set

A practical backup example

Consider a four-bedroom home using about 650kWh per month. During an outage, its priority circuit could include a refrigerator/freezer, eight LED lights, four fans, television and WiFi, a cycling water pump and two efficient air conditioners, averaging about 2.2kW while those loads are in use. For this example, we allow 20% for battery reserve and typical system losses, leaving 80% of the 18 kWh nameplate energy available for comparison: 18 kWh × 80% = 14.4kWh; 14.4kWh ÷ 2.2kW ≈ 6.5 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
  • 7.2kWp nominal PV array from 12 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 11kW Solar System for Off Grid power?

It can be configured for lighting, fans, tvs, wifi and computers; refrigerators, freezers, cctv and pos equipment; a water pump or selected air-conditioning circuits after starting power is confirmed. Final appliance quantity depends on simultaneous load and motor starting requirements.

How long will the battery last during an outage?

For example, a four-bedroom home using about 650kWh per month, with a refrigerator/freezer, eight LED lights, four fans, television and WiFi, a cycling water pump and two efficient air conditioners, could average about 2.2kW on its priority circuit during an outage. After allowing 20% for reserve and typical system losses, the 18 kWh nameplate battery provides about 14.4kWh for this preliminary comparison—approximately 6.5 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.
