There are various ways you can distinguish solar inverter PCBs and normal inverter PCB.

Normal inverter PCB will use gasoline, fuel, or electricity as the main source and uses that to produce electricity.

Solar inverter PCBs will use solar energy as the main source of power.

Also, you will install a normal inverter PCB at home or offices and they receive their power through a standard network and saves it in batteries.

When such current runs off, or the industry faces power disruption, it automatically initiates UPS.

It then proceeds to provide power until the standard power supply returns.

Solar inverter PCBs will extract power and convert direct current to alternating current.

Also, it will extract this power from grids that connect to photovoltaic solar cells and not power grids from electricity companies.

Normal inverter PCB will primarily convert direct current to alternating current.

Moreover, it will charge the battery using electricity.

Solar Inverter PCBs also operate the same way but have a unique feature that charges the batteries using solar panels.

Also, solar inverter PCBs can operate in a hybrid mode.

This means it can charge the battery using both solar panels and electricity.

Another difference between solar inverter PCB and normal inverter PCB is in how they perform.

Normal inverter PCB contains a system of inverters and batteries that attach to the power connection of your home or business premise.

As the power comes from the grid, the normal inverter PCB will charge the cells using electricity coming from the network.

When the power is off, the normal inverter PCB will use direct current from the cells and convert it into usable alternating current.

There are automatic switches that sense if the system has no power and needs to use change to UPS in the battery mode.

Also, off-grid solar-powered systems have solar panels, charge controllers, batteries, and solar inverter PCB.

The cells get power from the solar panels and the solar inverter PCB will convert the direct current to alternating current.

Besides, it can have automatic switches that sense if the solar grid is not providing solar energy.

In this instance, it will enhance the power source of the home or premise from the grid to the batteries.

What Are The Components OF Solar Inverter PCB?

Solar inverter PCBs have several electrical components, each performing a unique functionality.

Resistors will transmit electric current to produce voltage and release electric power in form of heat.

Besides, resistors are available in a wide array of materials and the colors illustrate their resistance value.


These are amplifiers that will control electronic signals in a solar inverter PCB.

Transistors come in numerous variations but the common version is the bipolar transistor.

A bipolar transistor has three pins, that is, the collector, base, and emitter.


These are the second most common part of the solar inverter PCB after resistors.

Capacitors will hold an electric charge within the solar inverter PCB and release it when another part of the circuit needs more power.

It will perform this by gathering opposite charges on two conductive layers.

Besides, these two conductive layers have insulating materials separating them.


These parts are similar to capacitors in nature since they store energy as magnetic fields when electric current flows via them.

Inductors will block signals within the solar inverter PCB, like an interference emanating from other electronic devices or equipment.


These parts operate by transferring electrical energy from one circuit to another circuit.

Transformers accomplish this task by increasing or decreasing the voltage.


These are components that allow an electric current to flow through in a single direction.

This functionality enables you to clock current from flowing in the wrong or opposite direction.

Besides, this effect will damage the solar inverter PCB.

One of the most common diodes is the light-emitting diode [LED] which operates by emitting light.


These components will detect fluctuations in the environment and respond by generating an electrical signal corresponding to the change.

After the detection phase, it will end in other parts within the solar inverter PCB.

The sensors will alter physical elements like air quality, light motion, or electric energy from the sound.

Solid-state Switches

Besides, the robot is precise and consistent than manual assembly.

This device picks the board by a vacuum grip and directs it to the pick and place area, where it orients and applies the SMTs.


Here, you will conduct the reflow process to ensure the solder paste solidifies and sticks to the components of the circuit board.

After the pick and place process, the board moves to a conveyor belt which moves to the reflow oven.

The oven has heaters that gradually heat the circuit board to around 250 degrees Celsius.

This temperature allows the solder to melt in the solder paste.

After melting the solder, the board moves through cooler heaters to solidify it.

This leads to the formation of permanent solder joints connecting SMDs to the PCB.

Inspektions- und Qualitätsmessungen

In this stage, you will test for the functionality of the board.

Besides, the movement that occurs during the reflow process can cause low-quality connections or a complete lack of any connection.

Shorts are one of the common side effects of this outcome since misplaced parts can connect to parts that they should not connect.


Depending on the type of solar inverter PCB, it may have several parts besides SMDs.

This may entail plated thru-hole [PTH] parts.

PTH are holes on the solar inverter PCB that go through the board as they assist in passing signals from one side to another.

Methods you can use to assemble PTH in solder inverter PCBs entail:

Manuelles Löten

This is a straightforward process as a single person will insert one part through a PTH.

The process continues for every PTH that needs fitting hence, making it a lengthy process.


This is an automatic process that entails various steps.

After placing PTH in place, the board moves through another conveyor system to a specialized oven.

Here, waves of molten solder will wash over the underside of the solder inverter PCB thus soldering all bottom pins at once.

Thru- Hole Component insertion Method Of Assembly

Thru -Hole Component Insertion Method Of Assembly

Final Inspection And Testing

In this stage, you will once again check for the functionality of the solder inverter PCB through a functional test process.

The test will simulate the operating conditions of the board as power and signals pass through the board.
