Best Off Grid Solar System To Buy

Off grid solar systems are popular since they provide a green alternative to your home’s electricity demands. Solar panels are a cost-effective substitute for traditional power sources. However, deciding on the best off grid solar system to purchase might be difficult. You might not know where to begin when acquiring off grid solar power systems for the first time. Because there are so many possibilities, you should educate yourself about off grid solutions before making a decision.

The main components of an off grid solar system

Customers wishing to acquire an solar off grid system have a wide range of options. This is because:

  1. Components of an solar off grid system: Every off grid solar power system is made up of a number of different parts. All components include batteries, charge controllers and inverters, wiring and racking.
  2. Many solar brands: There are numerous manufacturers for each sort of solar equipment – solar panels, solar inverters, solar cells, and so on.
  3. Lots of room for customization: off grid solar systems are totally modular. This means that a different size or brand may replace any component.

This blog contains our recommendations for the best off grid solar systems that meet every need.

Best Off Grid Solar System Types

AC and DC Coupled Off grids can power with either AC or DC coupled power sources. Common examples of AC coupled power sources include solar inverters, wind turbines, and backup generators (gensets). MPPT solar charge controllers and micro-hydraulic systems are examples of DC coupled power sources.

The size of the Off Grid Solar System usually determines whether the system is AC or DC coupled. Most small solar off grid systems below 6kW are DC-coupled.They use efficient MPPT solar charger controllers. Off Grid Solar System systems that are larger in size may be AC or DC coupled. The best Off Grid Solar System will depend on the type of off grid inverter charger and compatibility with other solar inverters (AC), or solar charge controllers(DC).

Modern multi-mode inverters are capable of being coupled in both DC and AC modes. This results in a very safe and adaptable off-grid solar power system. Best Off Grid Solar System has a variety of charging options. It can allow for black start operation in the event of the main inverter failure, backup generator failure, or battery depletion.

Key considerations when choosing a best off-grid solar system

  1. Summer and winter average daily energy consumption (kWh)
  2. Peak load (kW) – the maximum amount of power drawn from the load.
  3. Continuous load on average (kW)
  4. Daylight exposure factors include location, climate, orientation, and shading.
  5. Options for backup power during inclement weather or downtime

Keeping the above in mind, the main battery is the most critical component of an off grid solar power system. Chargers are also known as multi-mode inverters. Because they can operate in either off grid or grid tied modes.

Power of the Best Off Grid Solar System

Fortunately, if you know what appliances you will be using, determining the size of your off-grid inverter is simple. Add the wattage from all your lights and appliances together to figure out how much power you will need.

Don’t forget about voltage

even though most appliances operate at 120 volts. Assume your refrigerator requires 1,000 watts, your lights require 500 watts, and your phone and television require 200 watts. This totals 1,700 watts.In this case, we recommend that the inverter be at least 2,000 watts in order to give you some breathing room. (After all, you may be purchasing additional equipment in the future.)

Common off grid solar inverter powers

What is the most popular size that we sell? 4kW first, then 8kW. Different models and brands are available in a variety of sizes, with the majority of them stackable for increased power output.

Consider a pure sine wave VS modified sine wave.

Some off the grid solar systems manufacturers may refer to pure sine wave inverters. It’s not necessary to understand how they work. You just know that pure sine wave inverters produce “cleaner” power than modified sine wave inverters.

Pure sine wave inverters produce higher-quality power output that is comparable to (or better than) that of our grid. Modified sine wave inverters are less expensive, but their power output quality is lower.

As a result, modified sine wave inverters may cause issues with certain pieces of equipment. Motors, pumps, and compressors become hotter and wear out more quickly. Certain sensitive equipment (such as computers) may break or cease to function. These solar off grid system inverters typically produce background noise on stereo systems and degrade the video and audio quality of some televisions.

As a result, we do not recommend using modified sine wave inverters in the majority of applications. These potential problems can be avoided by using pure sine wave inverters for most of our customers off-grid.

Want to quickly tell the difference between the inverter total harmonic distortion (THD), rating. THD refers to power quality output. It will be listed on any inverter. Choose a pure sine wave inverter with a THD of 5% or less as a rule of thumb to avoid problems.

Technical specifications to consider for Best Off Grid Solar System


This is the amount of battery power that your inverter will deliver to your home under ideal conditions. The best peak efficiency rating is between 97 and 99 percent.


How much energy does your inverter use just sitting there? It goes without saying that you want it to be as low as possible.

Capacity for surges

What is the maximum amount of short-term overload that an inverter can withstand before “tripping”? Some appliances, such as water pumps or refrigerators, require up to two to three times the operating power to begin.

Output from a battery charger Most off-grid inverters come with a battery charger to charge batteries and provide a backup generator for the winter months. The rating of a battery charger is expressed in amps. The most reliable off-grid inverters will come with a 50-100 amp DC charger.

Temperature Range.

Off grid inverters are sensitive to high temperatures. If you intend to install the off the grid solar systems in a garage or a place affected by extreme temperatures. Please pay special attention to the temperature range.


The warranty period is one year, with most manufacturers offering a 3-5 year warranty extension option and a few offer a 10-year warranty extension option.All of these features are usually detailed on the product specification sheet. Please consult with your solar technician for assistance in comparing and selecting the appropriate inverter.

Features of the Best Off Grid Solar System

Your inverter may require special features. Take a look at these:

Battery charger

A charger allows a backup alternator to charge your best off grid solar system. Most larger inverters have this feature. These are referred to as “inverter/chargers.”

Grid-tie capability

Some off-grid inverters also have the ability to supply power to the grid.This feature is useful if the grid becomes available in the future or if you’re setting up grid-tied systems with battery backup.

Automatic generator start

A typical accessory is needed, but some inverters and charge controllers can handle it.

Best Off Grid Solar System Manufacturer

It’s also important to know the inverter manufacturer. Examine their track record and reputation. Off-grid inverters must be operational 24 hours a day, 365 days a year, for years at a time, so choose one from a reputable manufacturer. Off grid solar inverters in the United States require a variety of certifications to ensure safety and compliance.

The inverter in your home needs UL 1741 listed. UL 458 certification is required for mobile inverters used on boats and RVs. There are additional requirements for different applications such as UL1778 for uninterruptible electricity supplies and the KKKA-1822E standard to provide emergency services like ambulances.

For use in Canada use the CSA 107.1 standard. Outside of North America, use the international IEEE 1547.
