Battery
The LiFePO4 battery acts as a virtual storage, securely conserving electricity derived from solar panels for future use. Connecting batteries in a parallel or series circuit is an easy way to increase the overall voltage and capacity of your power source. When wiring them together, it's important to know that you need separate configurations for each connection; connect two positive terminals if you're operating in parallel mode, while connecting one negative terminal with another positive if working with a series setup. No matter which route fits best for your project needs, utilizing this device hook-up can expand both capacity and potential.
Inverter
Connect the inverter to your electrical panel: Once the batteries are connected to the inverter, you can connect the inverter to your electrical panel using the appropriate wiring. This will allow you to use the stored electricity from the batteries to power your electrical devices. The solar inverter ensures efficient electricity management by transforming AC current from traditional sources like a grid or generator into DC power to charge lithium iron phosphate batteries. Renewable energy is also converted back into AC form that can then be used to operate home appliances.
DC Circuit Breaker Box
The DC circuit breaker box safeguards against overcurrents, ground faults and electrical surges. Within it resides the all-important DC breakers for both inverter charger and lithium iron phosphate batteries; alongside a GFCI to snap circuits in case of illogical grounding scenarios or sudden voltage spikes from outside sources. Keeping your power flow under constant control!
AC Distribution Panel-
The AC distribution panel acts as a critical junction between the solar inverter charger, grid or generator and each branch circuit. It ensures that individual circuits can be easily disconnected in cases of maintenance or if an overcurrent issue arises. It's acts as your electricity control center, providing power from solar charged batteries to keep your lights on and appliances running; or if needed the generator powered backup. It also includes breakers for individual circuit disconnection in case of an emergency.
Charge Controller
Wire the charge controller to the batteries: Once the solar panels are connected to the charge controller, you can wire the charge controller to the batteries by connecting the positive and negative terminals of the battery bank to the corresponding terminals on the charge controller.
Solar Panels
Installing a solar panel mounting system is the key to securing your panels and allowing them to tilt and rotate according to the sun's movements. After determining what type of mounting system works best for your location, you can then attach your solar panels with appropriate hardware. To complete this setup process, wiring up the charge controller requires connecting positive/negative terminals of both components together - ensuring an efficient flow of electricity from panels into batteries.

Frequently Asked Questions

Can I sell power back to the grid with this Kit?

This isn't possible but the purpose of this kit is to gain freedom from the grid and use or store any extra power at your own will. Enjoy independence as well as greater control over how you generate energy.

Is any solar panel racking included?

We make it easy to mount and power up your solar panels. Along with our pre-drilled frames, each order includes z-brackets that can be used for attaching the panel to whatever structure suits you. If your location requires a rack system but none are available nearby, no problem – just add one of our ground racks when placing an order.

How long will the battery bank last?

Get peace of mind with the 10-year warranty on all of our batteries.. Our reliable LiFePO4 battery is designed to last you a whopping 15+ years, rated up to 6,000 lifecycles. To get an idea for how long your system will run each day - just divide its watt hours by your average load in watts – then sit back and relax knowing it's powered up all night.

Can I use a generator or the grid to charge my battery if necessary?

What solar panels are included in this kit?

This kit comes with 200W monocrystalline panels that come straight from some of the best names in solar! Our selection shows off only top-tier brands like Longi and QCells; each one backed by a 25 year warranty for worry-free power production. Get peace of mind knowing all our products are sourced either right in Canada and the US.

Can I expand this system if necessary?

Want more solar power? This kit has your back - you can easily add extra panels and batteries, or even stack an inverter for increased output. Make it fit any area of need with expandable options!

Can I install this system without the help of a Solar installer?

Our kits make installation easy for beginners, but for optimal safety and performance we strongly suggest leaving it in the hands of an experienced electrician and solar installer.

What type of appliances can this kit run?

You can check out the list of all appliances in the appliances tab above No need to worry about running those 240V appliances - this kit does come standard with 120V output, but there's always the option of adding an additional inverter for more power and versatility down the road.

How big is the kit once it's assembled? How much space will I need?

Each Kit is around 10m2 so you'll need a space like a garage or spare room. Installing solar panels requires a little bit of extra preparation. It's best to find an area in your home - like a garage corner or spare room - that can accommodate all the equipment while it waits to be installed. Each panel will come individually boxed and protected, so you'll have the freedom of leaving them inside or outside until they're ready for use.

Where is this equipment made?

All our products are made in the USA and Canada.

Do I need to keep the batteries inside or outside?

Lithium batteries thrive in environments similar to humans, as they prefer moderate temperatures. To ensure optimal performance and longevity it's important that you avoid storing them in extremely hot or cold areas such as a garage with extreme temperature fluctuations throughout the day; basements are generally an ideal place for lithium batteries since these spaces maintain steadier temps between 60F-90F degrees Fahrenheit. A battery can still be utilized when below 32° F but should not require charging until above 32° F.

Do I need to buy anything extra?

Our kits provide the essentials for your installation needs, but don't forget to stock up on those extra items from the hardware store like special tools, ground rods and wire. Also grab some UniStrut if putting in solar panels is part of your plan. You'll have all you need with our complete kit set-up.

How long does it take to receive my kit?

If you're based in the US, we strive to deliver your order within 7-15 business days. However due to increased demand for products, arrival times may vary and are currently averaging 15-20 business days.
