The Tiny House Solar Kit is a complete DIY off-grid solar kit, designed for tiny house owners needing to optimise power with space restraints. Tested by our solar experts and customers, it's proven to be the ultimate choice for tiny homes, with enough solar panels for tiny house owners to get the power they need.

Kit Contents, Specs, Manuals, and other Downloads can all be found in the yellow section below.

The Tiny House Kit Standard comes with a Standalone Inverter.

A Standalone Inverter has a standard 3-pin plug point, but requires a separate charge controller(incl.), and a battery charger(not incl.) for generator input.

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 Tiny House Kit run?

Below is an example of one day's total power usage, if you're getting at least 3 sun hours - this is ~4,800Wh 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?

(You may need to buy conduit to run the wire through, which is not included in the kit, as this will vary for every install). We also offer the tools required if you wish to make any changes or alterations to the base kit, and a number of related accessories. Product contents not showing?

Standalone (Standard)

The standalone inverter acts only as an inverter, requiring a separate charge controller (incl.) and optional battery charger (for generator input) to work in an off-grid system. This battery charger will need to be manually started each time it’s needed. The standalone inverter comes with a standard 3-pin outlet for immediate power use, and only requires an electrician if it will be wired into a switchboard.

More info

Hybrid (Upgrade)

The hybrid inverter is a more expensive unit. It combines the 3 components in one, and this allows you to connect a generator to easily charge your batteries. However, it lacks a 3-pin outlet and must be wired into a switchboard, so an electrician is required, resulting in a higher installation cost. A hybrid unit is required for Lithium batteries.

Universal

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.

Corrugated

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.

Ground

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.

Tilt

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.

How many solar panels for tiny house power?

For 1-2 people living in a tiny house in New Zealand, 4 390W PERC Mono Solar Panels should give you enough power throughout the year, even the less sunny days of a New Zealand winter. You can always upgrade to a hybrid inverter to allow for generator input as a back-up.

Trina Perc Mono panels are excellent solar panels for tiny house installs, and are our panel of choice in all kits. They use the latest technology to ensure their panels are as efficient as possible, meaning they produce 330W+ from a size where most panels only produce 270W at the best of times.

All our kits come with our 200Ah 12V battery, specifically designed for solar usage - no trickle charging needed. We are so confident in this battery we offer our warranty based on a 50% Depth of Discharge (DoD), while most companies only warranty a 20% DoD.
