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

The Bach Kit Standard comes with Gel Batteries and a Standalone Inverter.

  • Gel Batteries are 60kg each, have a 3-5 year lifespan, with 50% DoD.

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 Bach Kit run?

Below is an example of one day's total power usage, if you're getting at least 3 sun hours - this is ~4,500Wh 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?

Choose your inverter

Standalone or Hybrid

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.

Choose your battery

Gel or Lithium

Gel (Standard)

Our sealed Gel batteries weigh 60kg each, and should only be regularly discharged to 50% of their total capacity. They have an expected lifespan of 3-5 years depending on how well they are treated, and can easily become damaged from regularly being over-discharged or sitting partially charged. They work with either a standalone or hybrid inverter. They are a budget-friendly option for small scale set-ups.

more info

Lithium (Upgrade)

Our Lithium (LiFePO4) batteries weigh 30kg each, replace Gel batteries in our kits at a 1:2 ratio, and can be discharged up to 80% of their total capacity. They have an expected lifespan of 10-15 years with normal usage, and are more resistant to damage from over-discharging and sitting partially charged. They require a hybrid inverter to work. They are more economical in the long run for full-time living.

How to choose

Solar Panel Mounts

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.
