Construct Your Solar Battery Compartment Or Housing
The next thing youll need to prepare when you have the components ordered is the battery house. It could be a space in your current home, a separate shed, or a part of the garage.
You must ensure that the room where the battery is housed is safe from anything or anyone that could damage the battery. This could also avoid discharging the acids inside.
Please remember that most batteries dont do well with frigid weather, so they require some amount of temperature control.
If you opt for cheaper unsealed batteries, youll need to ensure proper ventilation in your battery compartment to impede the accumulation of hazardous hydrogen gas. This is because such types of batteries discharge the explosive hydrogen gas in minimal amounts when charging.
Most solar system installations have the primary power electronics, including inverter/s, charge controller/s, and safety fuses, shutoffs, and breakers in the battery compartment to minimize the costs.
What To Look For When Looking For Off Grid Solar Systems
Has a significant number of solar panels that can power up your whole place
More often than not, one solar panel will not be able to cut it when it comes to powering up an entire home. Make sure the off grid solar systems youre eyeing come with enough solar panels to power up all your homes appliances and lights.
Designed with solar panels that are durable and high-quality
Always go for solar panels that are durable and sturdy. Check out those with multi-layered sheets for extra lamination and protection from the elements. Youll also want a solar panel with corrosion-free aluminum framing to resist impact and damage, therefore extending the lifespan of your solar system.
If youre not sure whether a solar system youre eyeing is sturdy enough, you can always check out simple off grid system reviews left by other users to see their experience with the systems longevity.
The off grid solar system shouldnt be complicated to set up and install
If youre a newbie in setting up off grid solar systems, save yourself the hassle by going for easy-installation solar panel kits.
Go for those with easy-connect cables or panels that have pre-drilled holes to make mounting quick and convenient. Another thing that might help is longer connectors to give you the mobility to set up anywhere you want.
Components should be waterproof to prevent damage from the weather
Off-grid systems should work efficiently even when its cloudy outside
Basing Solar Setup Size On Usage
You can use this option if your aim is to maintain your current lifestyle as you switch from grid-tied to off-grid solar. To do this, you can simply refer to your monthly power bills to determine your electricity usage in kilowatt-hours.
You can then size an off-grid system of that size, although youd want to go a bit bigger say 10% more to allow for solar inefficiencies.

What Is A Solar Pv System
The second part, the solar PV system or solar photovoltaic system, means an electrical network that uses solar energy to supply electrical power. In simple terms, this is a power plant that only uses sunlight as its primary resource. It is mainly composed of solar modules, charge controllers, batteries, and electrical loads.
Thus, an off-grid solar system refers to a system that works without the support of traditional public utility services. It meets the electricity needs of the house, plant, or facility using the energy coming from the Sun.
Usually, this type of system can be accompanied by batteries or a backup generator to provide power during the night.

Install The Rooftop Solar Panels
- Place the solar panels on the roof according to the pre-project planning diagram you created and install the brackets.
- If attaching brackets to your van roof with adhesives, be sure to clean the area with acetone or something similar to ensure a good surface bond. If attaching to an existing roof rack with hardware, properly tighten all nuts and bolts and use lock washers so everything stays snug.
Pro tip: Keep in mind these panels will be exposed to wind and weather. Select the location and attachments to maximize the strength of the installation, and pay attention to aerodynamics. The lower they are positioned on the roof, the better.
Connect Batteries To Solar Controller And Activate Them
- Connect the batteries together to make a battery bank. We put ours in parallel, meaning the voltage stays the same but the capacity increases with each battery connected. Whenever connecting or disconnecting DC voltage items, always remove the cables from the negative terminal first, then from the positive terminal. When connecting them, do it in the opposite order to prevent sparking at the positive terminal.
- Connect the battery bank to the solar controller. We chose the Renogy Rover 40-amp Li solar controller, which has a positive and a negative wire input in the bottom of the unit for the battery connection. We attached our negative wire first, then our positive. Tighten your connections to make sure the wires are firmly attached. Note: This controller could be damaged, possibly destroyed, by connecting the solar panels to the controller before connecting the batteries. Check the specs on your controller so you don’t inadvertently damage it.
- Activate your batteries, if necessary. Our Renogy batteries have a “sleep” mode for storage or long periods of no usage. They came with a corded switch that plugs into the battery. To activate, push and hold the button for a couple of seconds. The button will illuminate from a dull blue to a bright blue .
- Check the solar controller to ensure the batteries are properly connected. Our unit has a display screen for this, but other units come with an indicator light or audible signal. Follow the manufacturer’s instructions.

How Much Does An Off Grid Solar Kit Cost
When it comes to putting in an off-grid solar system, you need to be prepared to cover a fairly substantial cost. What it comes down to is how much power do you need. Its the type of system that is expensive during installation, but in the long run? Installing an off-grid power system will pay off in a major way when you no longer have monthly utility bills that are subjected to rate hikes.
A smaller off-grid solar system that has enough wattage to run smaller appliances and other small duties, such as charging phones, will cost approximately $20,000.00 at time of publishing. If you are looking to go completely off-grid and remove other sources of electricity then you are looking at spending approximately $50,000.00 $70,000.00 for installation and start-up.
It is important to remember as well that when you install an off-grid solar system, the costs doesnt stop once installation is complete. There are on-going maintenance costs for the upkeep of the generator, fuel costs to run the system, and maintenance costs on the batterys and wires.
This can become pricy if you are running only an off-grid system but it truly depends on the rationale for leaving the local utility company. If you want to live a more alternative and greener lifestyle? Then an off grid system powered by the sun and backed up with fuel and batteries is the right path.
Don’t Miss: How To Calculate Savings From Solar Panels
Number Efficiency And Type Of Panels
There are price differences among different panel types, panel manufacturers and installation companies. We encourage you to compare and contrast your options to find the right fit for your home and determine the actual production numbers a solar system could provide you.
The number of panels you choose to install and the amount of power they are able to produce will affect the amount of money you will save on purchasing energy from the grid. A powerful solar system may be able to offset most or all of the power your home will need from the grid during the day, whereas a smaller system may not cover the total needs of your home.
Additionally, solar panels will not produce energy overnight. Without a solar battery system to store excess energy produced during the day, you will still need to purchase electricity from the grid during non-daylight hours.
Route And Attach The Solar Panel Wires
- Wire the individual solar panels together. Your method will depend on whether you’re wiring them in series or parallel. We wired in parallel, so we connected the positive wires together, then the negative ones. Our kit came with connectors to combine the four positive wires into one wire, and another to combine the negatives. That meant only making a hole in the roof the size of two wires instead of eight super helpful.
- Next, install any inline fuses required by the manufacturer on the positive wire. This fuse plugs inline to the positive-side wire.
- Select where you want your entry hole for the wires into the van, and route the wires accordingly. We ran ours down the driver’s side rear corner because we had a clear run from the roof to the floor. Most people drill a hole in the roof to feed the wires to the inside. Some manufacturers supply waterproof enclosures others you can find online.
- Attach the panel wiring securely between the entry point and the panels. This can be done with wire ties, screws with wire clasps or adhesive sealants.

The Federal Tax Credit offers up to a 26% rebate on the price of a new solar installation. Additionally, the Database of State Incentives for Renewables & Efficiency can help consumers find discounts of up to several thousand dollars within their states.
Ac Vs Dc Coupled For Off
Why would you use an AC coupled off-grid system rather than DC coupled?
Large AC coupled off-grid solar system with a 9.2kW Solar array and 26kWh lithium LFP battery bank.
Modern AC-coupled off-grid systemsuse solar inverters to convert solar DC power directly to AC which can then be used immediately by most appliances during the day. This is very efficient, especially when powering high loads such as air-conditioning systems, modern kitchen appliances and water/pool pumps. Additionally, the installation cost of AC-coupled string solar inverters is lower for larger systems above 6kW, due to the multiple MPP trackers, higher string voltage up to 1000V, and higher capacities up to 10kWp single phase.
Note: If an AC-coupled system is used for off-grid, the solar inverter must be compatible with the battery inverter/charger to enable precise charge control. This is required so the solar generation can be ‘managed’ or ramped up and down to ensure safe and accurate battery charging. There are several management systems used by different manufacturers, such as frequency ramping or direct communication as used Selectronic combined with Selectronic certified or Scert solar inverters – refer to manufacturersâ specifications.
