When it comes to load requirements, the price of the solar inverter is directly proportional. The higher the price of a solar inverter, the more load it must handle. Just so you know, the price difference might be significant depending on the amount of load you require. Let’s look at an example to better grasp this:
If there are two structures with the names A and B.
Building A requires electricity to operate basic electrical equipment such as fans, tubes, LED lights, televisions, and so on. Building B, on the other hand, includes heavy-duty equipment such as air conditioners, microwaves, and geysers.
Because Building B consumes more energy than Building A, it would require:
- The more no of solar panels,
- The more power storage
- The higher capacity solar inverter
Types Of Solar Inverter (On-Grid/ Off-Grid):
On-Grid (also known as grid-tied) and Off-Grid solar inverters are the two types of solar inverters available on the market. In comparison to on-grid solar inverters, off-grid solar inverters are more costly. Because residences with on-grid inverters are linked to the local grid, this is the case. When the solar panel system produces less electricity, on-grid solar inverters pull energy from the local grid. The Off-Grid inverters, on the other hand, have no connection to the local grid and are entirely reliant on solar panels for power generation.
This is because they utilize batteries, which raises the overall cost of the system. In addition, depending on the battery’s lifespan, there is a replacement cost.
The technology of The Solar Inverter (MPPT / PWM):
The two forms of inverter charge controller technology used in solar inverters are PWM and MPPT, which have an impact on the cost of solar inverters.
MPPT – Maximum Power Point Tracking
PWM – Pulse Width Modulation
In comparison to PWM inverter charge controllers, MPPT solar inverter charge controllers are more efficient. As a result, MPPT inverter controller technology is more costly than PWM solar controller technology.
The solar inverter charge controller’s main goal is to keep the batteries from overcharging. The charger controller converts the solar panels’ electricity into the appropriate amperage/voltage before sending it to the solar battery.
The PMW Solar Charge Controller operates on the same concept as a basic electrical switch, ensuring that the voltage of the solar array and the solar battery is always equal.
The PWM controller lowers the solar array voltage down to the solar battery voltage if the solar battery voltage is lower than the solar array voltage. Solar panels with great power generating capacity are forced to run at low voltage, resulting in a significant waste of produced electricity.
The MPPT charge controller, on the other hand, monitors the voltage and current of the solar panels in real-time and guarantees that the solar array delivers the greatest amount of energy to the solar battery. It takes the maximum amount of electricity from the solar panels and then acts as a modulator, varying its output voltage to match the batteries. The current outflow is raised if the voltage has to be stepped down to ensure maximum power output and faster battery charge.
