Off the Grid Water Supply

Our Off-Grid Courtney Portable Home comes with a gutter kit with an easy-to-install clip system. The gutter will collect rain water as it flows off the roof, which can then be collected in a rainwater tank. To make full use of your rainwater, you will need a supply system with a suitable pressure pump capable of delivering water at, or near mains pressure.

If you live in an area with low rainfall, you can arrange for water cartage service and have clean drinking water delivered to your water tank on a regular basis.

Off the Grid Greywater & Wastewater Management

The Courtney Portable Home comes equipped with a wastewater outlet which can be connected to your septic tank, if you have one on your property. If septic services are not available onsite, a portable waste holding tank can be used to hold household sewage. They are self-contained and do not need to be connected to any external services. They will need to be emptied (called “pumping out”) by your local waste disposal company regularly.

There are several different options for storing or getting rid of greywater, which is domestic wastewater generated from the shower, laundry and sink. The Courtney cabin comes with a greywater outlet.

Collect in a Bucket or Large Container
The simplest way to reuse greywater is to place a bucket or container under the greywater outlet. Simply take the water-filled container and water the plants with it, or flush the toilet with it.

Collect in a Greywater Filtration System
A professional greywater system can be used to pass the water through multistage filtration mechanisms. They then move the filtered water into irrigation systems that automatically water your garden.

Send to Sewer
This method doesn’t involve reusing greywater, but if you have access to a sewer or septic system that’s not at capacity, you could just send your water there.

Other options include installing a surge tank or a branched drain system (for long-term off grid living).

Off the Grid Energy Source

When it comes to an alternative power source, off grid solar system is the most common choice. PennyGranny recommends three off grid solar system options that can be purchased from our partners and which are suitable for our Portable Homes. Each option include examples of what appliances can be run from the setup – please note, this will ultimately vary depending on a person’s power usage habits.

Each off grid solar system kit is plug and play and includes all the basic wiring and mounting frames for the solar panels. The included mounting frame kit is a modular racking system that goes on to the existing roof screws. It is designed to be mounted flush on the roof and a cable run down from there to the power unit. No hardwiring is required, you will only need to run an extension cord from the provided outlets to the appliance:


Option 1: Budget Off Grid Kit

Includes 740W of solar panels, 3600W inverter and 3.6kWh battery. Suitable for the bare minimum setup to run a small cabin.


Option 2: Basic Off Grid Kit

Includes 1.1kW of Solar Panels, 3600W Inverter and 5kWh of Battery. Suitable for 1-2 people.


Option 3: Premium Off Grid Kit

Includes 1.4kW of Solar Panels, 3600W Inverter and 10kWh of Battery. Suitable for a small family.

Backup generator included to cover periods of low solar production in winter and occasional use of an air conditioner.
