I’ve got more questions, how can I contact you?
Email us at email@example.com or message us on Facebook or our on-site livechat for any questions or to get a callback.
What payment options do you offer?
Credit card, EFTPOS, bank transfer, and cash are all accepted.
What kind of financing do you have?
Afterpay is available on items under $1200, we have also had customers use Q cards and Gem Visa to purchase kits. We can also help with WINZ quotes.
How much does shipping cost?
There is a $300 shipping charge (incl GST) on all full size kits (Tiny House, Bach, Weekend Warrior and Freedom). Smaller kits such as the Starter Kit will be $150 (incl GST). Shipping charges on individual components vary between $10 - $50 depending on weight. Please contact us if you want to ship to a rural address as you may incur an extra cost.
Where are you? Can I come see you in person?
We operate out of Wiri. Get in touch if you’d like to come chat and see the products in person, and we can set up a time for you to visit.
Do I need an electrician to wire everything up?
Most of it can be wired up yourself if you feel comfortable doing it. If you plan to wire the inverter into a switchboard, you will need an electrician for that part as its 240V AC.
Are your products compliant with NZ Electrical Standards?
All our products have the required certification and compliance to be sold in New Zealand, and these documents can be supplied with purchase.
What’s the warranty on your products?
Our panels have a 10 year limited product warranty and 25 linear performance warranty. Our batteries have a 3 year limited product warranty (based on 50% depth of discharge). Our inverters have a 1 year product warranty and charge controllers have a 2 year product warranty.
What panels do you sell?
We include Trina 330W to 345W PERC Mono panels with all our kits, because they're the most efficient panels in New Zealand for off-grid use. These panels feature up to 18.94% conversion efficiency, severe weather resilience, and excellent low-light performance, so we're confident that they'll produce the power you need, even on cloudy days.
Can I cook or run an electric water heater on solar?
We recommend using gas for cooking and heating applications, where possible, as these are high consumption appliances and will drain batteries heavily. Learn more here.
What kit do I need?
To get an idea of what you'll need, check out the "What is this kit capable of running?" section on each kit page. You can also contact us for advice.
To work out more clearly what kit you’ll need, start by calculating your expected daily usage of all your appliances in Wh - you can find calculators online. Then take this figure and find a kit that will produce the appropriate Wh for your lifestyle.
The Wh production of each kit changes over the course of the year due to changing sunlight hours. In the peak of summer most places of New Zealand get between 6-8 sunlight hours, and in winter you get less sunlight hours normally between 3-4. This means you may need to adjust your usage to conserve energy over the year, or get a larger kit to keep up during winter. In the details of each kit you will find an indication of what you can run on that kit, but as a guide, here are the approximate Wh productions of each kit over the year, based on 7 and 3 sunlight hours:
Starter Kit: In ideal summer conditions this kit can produce over 2200Wh per day, and during winter about 945Wh.
Weekend Warrior: In ideal summer conditions this kit can produce over 4300Wh per day, and during winter about 1860Wh.
Tiny House: In ideal summer conditions this kit can produce over 6615Wh per day, and during winter about 2835Wh.
Bach Kit: In ideal summer conditions this kit can produce over 8,820Wh per day, and during winter about 3,780Wh.
Freedom Kit: In ideal summer conditions this kit can produce over 17640Wh per day, and during winter about 7560Wh.
Can I add more panels to an existing kit?
For our 48V systems, the charge controller included will usually allow you to run a few extra panels. For example the 50A Charge Controller in the Bach Kit will run up to 6 x 315w PERC mono solar panels. The 100A Charge Controller in the Freedom Kit will run up to 14 x 315w at 48V.
For our 24V systems (Weekend Warrior, Tiny House), you wouldn’t be able to run more panels with the provided charge controller. Check out the rated charge power in the charge controller description to find out how many panels you can run. https://gridfree.store/collections/charge-controllers
Please chat to us if you'd like to customise a kit, and we can help sort you out.
Can I add more batteries to an existing kit?
More batteries can be added to all of our off-grid solar kits. Keep in mind that you must add a string of batteries that is of the same voltage as your current ones. If you have a 24V system that is made up of 2 x 12V 200Ah batteries, you’ll need to add in another 2 x 12V 200Ah batteries and have them connected in parallel to your existing battery bank. This will give you a 24V 400Ah battery bank and roughly 9,600kWh in capacity.
How many days will the batteries last without sun?
It depends on your daily consumption, to calculate this take 50% of your battery capacity and divide that by your daily consumption.
9.6kwh * 0.5 = 4.8kwh
4.8kwh / 1.5kwh (Daily consumption) = 3.2 days
How many years will the batteries last?
The lifespan of our Gel batteries is typically 4-5 years, but if treated well, and not discharged heavily can last over 8 years.
The lifespan of our Lead Carbon batteries is typically 8-10 years, but if treated well, and not discharged heavily can last over 12 years.
Do the batteries need maintenance?
Our Deep cycle Gel batteries are completely maintenance-free.
Do remember to trickle charge the batteries every 3 months if you’re not going to be using them.
How much power can I generate?
Use the wattage output of your panel and multiply by the number of panels you’re running. Then multiply by the average sunlight hours in NZ (4 hours). This will vary across the year.
The Bach Kit runs 4 x 335W panels, making it a 1340W array.
Over four hours you’ll produce 5360Wh
What can I run?
What you can run varies from kit to kit, and is affected by the efficiency of your appliances and how you use them. In the details of each kit, we’ve indicated common items that can be run on them. The easiest way to work out what you can run is to work out what you want to run, how much power you’ll need for those items, and find a kit that can maintain your usage. If you're willing to be conservative with your power usage for a few days a year, you can make significant savings in your set up. Learn more here.
