Before buying an off-grid inverter, it is essential to know how much your electrical load is. This is a crucial decision since it will determine the size of your inverter. In addition, you need to be honest with yourself when it comes to your usage habits. Here are some tips to choose the right off-grid inverter:
A high-quality off-grid inverter will be easier to install than one with only the basic features. It will also be more efficient, allowing you to collect more solar power without using the utility grid. An inverter will also have a multi-color LCD display and an IT mode to monitor battery voltage. This device will also increase the lifetime of your solar battery. The price of an off-grid inverter should be determined after carefully checking its features and specifications.
The off-grid inverter price will depend on how much energy you need to produce and store. Some inverters are so expensive that they can cost a couple of thousand dollars. A better option is to invest in an off-grid system with a larger storage capacity, which will smooth out your energy production. The inverter will store excess energy and convert it into electricity. Depending on your location, you may also need a backup system, such as a wind turbine or generator.
The off-grid inverter should be designed to maintain 50Hz or 60Hz in the USA or Africa. Depending on your needs, you can choose between a single or dual-frequency off-grid inverter, which is perfect for cabins and small homes, and a multi-frequency system. A 16-kW or higher off-grid inverter is recommended for large off-grid houses, farms, and businesses.
