Why Is It So Hard and Costly to Implement an off Grid System?


Typically, off grid systems are only used when it is very important. Areas with no utility power grid, where the weather conditions account for power outages due to storms, etc.

Solar systems off grid require more technical skills and are more expensive to implement since they require more components such as charge controllers and batteries, so they require higher technical skills and are more complex in installation. Due to this, the off grid solar system market grows, and most manufacturers / suppliers search for and implement new methods and services to reduce costs and complexity including:

1. Off grid solar system package

One of supplier / manufacturers ways to make the off-grid system easier is to provide as a package. The package should contain solar panels & solar charge controller & inverter & accessories, so you just connect / assemble the system and run, the good thing is you don't need to contact the supplier anymore as you have all parts in the package.

2. Choosing the most flexible off grid inverter

The solar off grid inverter is the brain of off grid system, the more flexibility of the inverter the more easy and reliable off grid solar system you get. For instance, getting the off-grid inverter that incorporate charge controller instead of separate one, also the capability of the inverter to be connected with both external generator and power grid is an important feature. Moreover, getting the feature of inverter capability to sell back excess energy to power grid is great profitable feature to the end user.

3. Solar off grid inverter capability to be stacked with another inverter

I find that feature stunning. Most off grid solar systems require oversizing, so that you can add more loads (appliances, equipment, etc.) to the system after it is built. Extending solar panels is easy, but can you add a second inverter? Yes, provided your first inverter accepts stackable inverters. We recommend keeping this feature in mind when purchasing your first or main inverter.

4. After sales services

Since most off grid solar systems are located in remote areas, troubleshooting will usually take a long time, and in some cases, will be costly, if spare parts are needed. So, look for inverters with long warranty periods and deal with a reputed supplier who has installed many solar systems for many years, and make sure the supplier can provide references. The remote monitoring system can make troubleshooting easier, so it's important to ask the supplier if they can provide a reliable monitoring system.
