Off-grid power systems are ideal for situations where there is no easy access to the grid or in remote locations that require self-generated power. These systems are self-contained units that include everything you need to control and store off-grid electric power from renewable sources.

Setup is simple. Connect your renewable energy source to the power system and connect the system to the building. You can use a solar array or wind turbine to charge the batteries within the unit. That charge is then delivered to the building it supplies.

Alternatively, for sites where it’s not feasible to install a renewable energy source, power units can be recharged via a generator and you’re good to go. It really is that easy!

Need Help Choosing a WattGrid System?

Knowing the total constant load (in watts) of your appliances, equipment and machinery will help you choose the most appropriate WattGrid system.

The constant load is the total wattage of everything that will be running at the same time for the whole day or a large part of it. For appliances that run for a limited period of time a generator can be used to provide a short power boost.

For example, if you were running a fridge (280w), freezer (280w), lighting (100w) and CCTV (60w) around the clock or in the case of lighting several hours at a time then your constant load would be 720w (280w + 280w + 100w +60w).

Use the table below to choose the WattGrid system that covers your maximum constant load.

System Max. Constant Load
WattGrid 1600 1,200w
WattGrid 3000 2,400w
WattGrid 5000 4,400w
WattGrid 8000 6,500w
WattGrid 10000 8,000w
WattGrid 15000 12,000w

Each solution has been designed as a completely self-contained system that can connect to the energy source and your building and begin generating energy in the shortest possible time.

The benefits of a WattGrid off-grid power system include:

  1. Installation inside or out as they are completely self-contained units
  2. Generate energy from solar or generator
  3. Installed with the minimum of fuss
  4. Configured and expanded as required
  5. Moved easily for temporary sites

WattGrid off-grid power systems are available in a range of capacities and are ideal for a range of situations. Select the best option for your needs or call us to discuss.

DIY Off-grid Power vs Off-grid Power Unit

When planning a DIY off-grid power generation system you need to consider solar panels, solar inverter, charge controller, batteries, monitoring, generator and any power conditioning equipment you may need. Add cabling, jointing and lots of accessories and you have quite the shopping list!

With an off-grid power unit, all you need is the unit, solar panels or a generator. All the other hardware is encapsulated into a single system. Connect your solar panels to the unit and connect the unit to your building or equipment. Optionally, add a generator for recharging the power unit if the situation requires.

This provides a very straightforward way to build, install and manage a complete off-grid power solution with the minimum of fuss and installation.

Key Advantages of Sunstore Off-grid Power Systems

DIY off-grid power is an excellent way to design and construct renewable energy on your own terms.

There are some key advantages of using an off-grid power system over a DIY solution.

  1. Can be installed inside or outside depending on requirements.
  2. Can take energy from multiple sources including solar panels, wind and generator.
  3. Self-contained units that are literally plug and play.
  4. Can be configured for a multitude of uses from domestic to commercial.
  5. Can be moved and reused, ideal for temporary installations.

All Sunstore off-grid power units are constructed to be weatherproof, secure and quiet. They can be used within buildings or sited outside. They are compact, require minimal site preparation and can be lifted in with the minimum of fuss.

One single unit includes all the hardware necessary to accept, control, condition and store energy generated by renewable sources and feed it into a building for use. All you will need are some solar panels and a means to connect the unit to the building.

You can’t get more convenient than that!

Off-grid Power Generation

We take nothing away from DIY off-grid power systems as they offer the ability to customise a solution to your particular needs. When time and convenience are paramount, or when you have temporary requirements, a self-contained off-grid power system is the way to go.

They can be delivered via crane or forklift and can be installed within a couple of hours. All they require is a stable base, a connection to the power generation source and a connection to the building. Add a generator as backup, or to recharge the unit where no renewable energy sources are available, if required.

Sunstore’s off-grid power units are used in residential situations, commercial, farms, building sites, remote monitoring stations, mobile and telecommunications installations and all manner of situations where there is no grid connection but reliable power is required.

If you’re looking for a simple solution for your off-grid energy requirements, an off-grid electric unit from Sunstore could be the answer!
