How to Connect Inverter to Solar Charge Controller?

What is an inverter for solar panels?

Inverter means those who invert something. Indeed we use AC and most devices are designed for AC. The solar panel generates DC and if we wish to use it to meet our load then we must convert it into AC power. For this reason, the inverter is used to convert DC power generated from the solar panel into Alternating current (AC). It is noted that if we want to use only DC power then we don’t need to use an inverter. However, if we would like to connect the inverter then we must connect it to the charge controller. So, let’s see how to connect an inverter to the solar charge controller. 

How to wire solar panels to inverter?


Charge controller means that those control charge. It means a charge controller is used to control the overcharge and over discharge so that the overcharge does not harm the battery. There is a basic question that how to wire solar panels to an inverter. We have told you before that solar panel wiring is very simple. However, let’s see how to connect inverter to solar charge controller.

  • First of all, connect the wire with the positive and negative terminals of the solar panel (red is positive, and black is negative).
  • Connect with controller positive and negative terminal.
  • Bring two positive and negative terminals from the controller and connect them with the positive and negative battery terminals.
  • Connect a wire between the inverter and the battery’s positive and negative terminals.
  • Bring output from an inverter for AC output and connect it to the AC load or AC distribution box.

It is noted that the charge controller has three positive and negative terminals whereas the technician can connect it with the DC load beside the solar panel and battery connection.

How to connect solar inverter to distribution board?

Why do you need an inverter for solar panels? We have been told several times an inverter inverts the power. It means the inverter inverts the DC power into the AC power. If you want to run only a DC load then you don’t need an inverter. On the other hand, if you wish to meet AC load then you have to use an inverter. It is noted that solar panels generate DC electricity. 

How to connect inverter to ac panel? It is a very simple connection process. We have given the connection process above. However, we are giving short tips on how to connect solar inverter to distribution board. First of all, connect the inverter input terminals with the battery terminals and connect the inverter output with the AC panel or AC distribution box. Now you are ready to run your electronic devices.

How to connect inverter to solar charge controller?

How to connect solar controller to inverter? You can directly connect the solar charge controller with the inverter. In this case, you cannot store electric charge because the battery is not available in this section. On the other hand, if you would like to connect with a battery then you have to connect it to the charge controller.

The battery will store the charge to use off sun period. It is noted that we get solar electricity in two ways. One way is direct power which means the solar panel will send direct power to the inverter. The second one, the battery will store the charge and the battery charge can be used in the off-sun period.  

What is a solar inverter and how does it work?

The solar inverter is an important feature of a solar power system. The solar inverter transforms the outputs of solar energy into the operative form of electricity from solar panels. A solar inverter performs well by captivating into the variable direct current or output of “DC” through solar panels and reorganizing it into alternating 120V/240V Alternating current, or output of “AC”. The electronics of your home operate on AC which is why solar inverters should change the DC output which can be accumulated from efficient solar panels.


The rays of the sun fall over the solar panels are created by semiconductor layers of silicon. Two types of layers are present here; one is positive and another negative which is fixed by the junction. The layers of the semiconductor absorb the light when the sun shines and directs the energy to the PV cell. This energy moves, bumps of electrons lose and they pass within the positive and negative layers, which generates electric current known as Direct Current “DC”. This energy is stored in the battery or the inverter. 

What do solar inverters do?

According to PV Evolution labs (PVEL), solar Inverters are the strong working components of the solar array. The inverter manages the operational features of any component of the PV system. With the increase of interactions along with the system grid and with aid of smart systems, the workload has doubled. Here are 5 duties that solar inverters do, for instance:

  • Transform DC to AC power. 
  • Increase power output Cooperate with the grid
  • Outline over power production 
  • Secure safe system operation 

Transform DC to AC power

The key feature of an inverter is to transform direct current (DC) power that is generated alternating current (AC) power that can be used for businesses and houses. 

Increase power output 

Inverters track the solar arrays’ voltage to know the maximum power, and where modules can function well. The shaded modules can connect to the wrong peak which lessens energy production. 

Cooperate with the grid

Better inverters can switch into the reserve mode when the voltage changes. This process makes sure that minimal voltages are getting out of range and unsteady power production. 

Outline over power production 

Some inverters can communicate through the hardwired Ethernet and WI-Fi. This communication can lead to cyber-attacks. Solar owners can track these problems and see the power production information, error codes, and diagnostics with the help of “SolarEdge”. To fix this problem permanently, the solar owners can invest in better monitoring services, and fix the problem of multi-inverter arrays along with third-party vendor “Solar Log”. 

Secure safe system operation

According to PVEL, due to material degradation and a stale system, the inverters may shut down. Since inverters perform multiple tasks and several electronic parts; they may not perform well than other components of the PV system. 

What is an off-grid solar inverter?

An off-grid solar inverter is delineated to work in without being attached to the local utility grid. This off-grid solar inverter operates the energy originated by the best solar panels and renovates to the alternating current that is utilized by your electronics and for lighting. In contrast to the grid-tied solar inverter, the off-grid inverter operates a battery bank rather than sending the alternating current energy to the grid.

The finest off-grid inverters have an aptitude for EV charging and they save energy for the foreseeable future. This inverter will let you be self-reliant and you don’t have to depend on other providers who are not trustworthy. If you want to buy an off-grid solar inverter you must go through some factors that might help you to buy a better one. 

  • Size of the inverter
  • Modified Sine Wave
  • Efficiency
  • Battery charger size
  • Warranty
  • Manufacturers

Final word of how to connect inverter to solar charge controller

Indeed if you would like to install solar panels then you need some crucial equipment like a charge controller, batteries, inverter, wire, stands, and others. We have shown above that how to connect inverter to solar charge controller. It is a very easy connection process you need to remember the connection terminals (positive and negative). It is noted that you are able to install solar panels without a charge controller but your battery will never be safe from overvoltage and over-discharge. To safe your battery and get a stable power supply connect the solar charge controller. If you would like to know more details about solar panels then visit openread.
