The Retreat Kit


The Retreat Kit is the ultimate off-grid energy solution, helping you build your perfect off-grid retreat in NZ. This is one of our largest off grid solar systems, and it provides plenty of power for everything you need in your home. Includes a hybrid inverter/charger and Lithium batteries as standard (electrician required). The Retreat Kit was built to provide off-grid solar power for bigger families even in the most remote locations.

Kit Contents, Specs, and Manuals can all be found below.

This kit is on pre-order, please call to confirm arrival

Installation: The solar panels and their cables are the only parts in these kits that are okay outside. The charge controller, inverter, and hybrid inverter are not IP rated and should be kept away from moisture including condensation.

DoD: Depth of Discharge. Refers to what percentage of the total battery capacity can be used regularly without damaging the battery. For example, with a Lead Acid battery, a 50% voltage reading should be considered 0% power left, and you should stop using power.

What can the Retreat Kit run?

Below is an example of one day's total power usage, if you're getting at least 3 sun hours - this is ~24kWh of energy per day and can be expected for >80% of the year. (Learn more.) These items are a guide to what you might run over one day, and they can be swapped out to suit your needs within the generation estimate. (Read more.) We highly recommend having a back-up generator with these kits if you won't be able to conserve power during low-sun periods.

Not sure how much power you need? Read this article to learn how to calculate your needs.

This example doesn't account for days when you may have to cut back on power use (or supplement with a generator) due to several days of poor weather preventing your batteries from fully recharging each day. Learn more here. Our kits should not be used for vital or life-supporting systems, and we recommend finding alternative solutions for Water/Space Heating, Cooking, or EV charging to maximise your budget - Why?

How to choose

Solar Panel Mounts


The Universal Roof Mount allows you to mount your panels flat on any type of roof along a pair of rails. The rails are attached to the roof with L-shaped brackets, and the panels are clamped to the rails, making it much easier to mount four or more panels on your roof.


The Corrugated Iron Roof mount performs similarly to the universal roof mount, but it is a rail-free option that sits in the grooves of corrugated iron. The mounts are secured to the roof and then the panels are clamped onto them directly instead of rails.  


The Ground mount allows you to mount your panels on the ground along a pair of rails attached to a triangular frame, and the panels are clamped to the rails. The frame is mounted on something secured in the ground, and the angle can only be adjusted during the install.


The Tilt mount allows you to mount your panels on a flat/low pitch roof at an angle to maximise solar energy, adjustable by up to 15 degrees after the initial install. The rails are attached to a triangular frame mounted to the roof, and the panels are clamped to the rails.
