#1. How To Convert Existing Inverter Into Solar Inverter

For converting an existing inverter into a solar inverter, you need to install a solar conversion kit i.e. solar charge controller. A solar charge controller is basically a small size solar device that connects between solar panel and inverter.

The solar charge controller has an inverter plug-in-slot. You just need to attach your inverter with a solar charge controller. Further it also connects with your solar battery. These simple steps can upgrade your existing home or office inverter to a solar inverter.

Hence, for converting your normal inverter to a solar inverter, you will need to introduce two main components to the system (In case, they are not already installed). These are solar panels and solar charge controllers. Or you can go with a solar conversion kit that has every component necessary for conversion. 

#2. Why To Convert Existing Inverter Into Solar Inverter?

A normal inverter is a simple device that only deals with alternating current i.e grid electricity. On the other hand, a solar inverter is a more advanced device that utilizes solar energy.

Solar energy is a cheap and clean source of illumination and electricity compare to grid electricity. It is generated by the solar system in the form of DC electricity where a solar panel is used to absorb the sunlight and a solar inverter is used to regulate the passing voltage.

Why to convert existing inverter into solar inverter

Since a normal inverter can’t deal with DC power, we can’t use it in a solar system. That is why we need a solar inverter to work on the solar energy. A solar inverter has inbuilt features to convert DC power into AC power for the solar system.

In simple words, for converting the solar power into electrical power we need a solar inverter instead of normal inverter. This power conversion is important because in our homes we cannot serve DC power directly to run our electrical appliances.

#3. Benefits Of Converting An Existing Inverter Into Solar Inverter

There are a number of benefits that you get after converting your existing inverter into solar inverter. Let’s have a look over these benefits in short.

  • Helpful in reducing high electricity bills.
  • No need to purchase solar inverter separately for a solar system.
  • Perform both function of normal inverter and solar inverter simultaneously.
  • Block the reverse current flow from solar battery to solar panel.
  • Best alternative to generate electricity at your own place.
  • Ensures the safety of solar panel as well as solar battery.
  • Less expensive compare to purchasing a new solar inverter.
  • Increase solar battery life and prevents it from overcharging.
  • Optimum use of old existing inverter.

#4. Types Of Solar Conversion Kit

A solar conversion kit allows your home electrical system to manage and regulate the electricity generated by the solar panels in the form of DC. It is basically a connection between solar panels and the regular inverter. A solar conversion kit can use different technologies to function.

On the basis of these technologies, the kits are categorized into three main types. These different types are as mentioned below.

#5. MPPT Solar Conversion Kit

MPPT solar charge controllers work on the Maximum Power Point Tracking (MPPT) technology.
