SolarEdge Solar Inverters Prices:
If we talk about the prices of solar inverters, it depends on some factors:
- Load Requirement
- Inverter Type (On-Grid/ Off-Grid)
- Technology (MPPT / PWM)
- The Features of The Solar Inverter
If we talk about the load requirement, it is directly proportionate to the price of the solar inverter. The more load the solar inverter requires higher its price. Just for your knowledge, the price difference can be substantial, It completely depends on your required load. For better clarity, let’s understand this with an example:
If there are two buildings named A & B.
Building A needs the power to run basic electrical equipment such as fans, tubes, LED bulbs, TV, etc. While building B has heavy load equipment such as air conditioners, microwaves, geysers, etc.
Since building B’s power consumption is more than the building A, it would need:
- The more no of solar panels,
- The more power storage
- The higher capacity solar inverter.
Types Of Solar Inverter (On-Grid/ Off-Grid):
There are two types of solar inverters available in the market: On-Grid (also known as grid-tied) & Off-Grid solar inverters. Off-Grid solar inverters are more expensive in comparison to On-Grid solar inverters. The reason is, it homes with on-grid inverters are connected to the local grid. On-Grid solar inverters draw energy from the local grid whenever the solar panel system produces less power. While the Off-Grid inverters have no connection to the local grid and these are completely dependent on solar panels for power generation.
That’s because they use batteries which adds to the cost of the entire system. Also, there’s a replacement cost involved depending on the longevity of the batteries.
The technology of The Solar Inverter (MPPT / PWM):
Solar inverters have two types of inverter charge controller technology: PWM, MPPT, which also affect the cost of solar inverters.
- PWM – Pulse Width Modulation
- MPPT – Maximum Power Point Tracking
MPPT solar inverter charge controllers are more efficient in comparison to PWM inverter charge controllers. That’s why the MPPT inverter controller technology is more expensive than PWM solar controller.
The main motive of the solar inverter charge controller has to prevent the batteries from overcharging. The charger controller modifies the power generated from the solar panels into the required amperage/voltage and then sends it to the solar battery.
The PMW Solar Charge Controller works on the principle of a basic electrical switch which ensures that the voltage of the solar array is equal to the voltage of the solar battery always.
If the solar battery voltage is lower than the solar array voltage, the PWM controller steps the solar array voltage down to the solar battery voltage. There is substantial wastage of produced electricity in this process as the solar panels with high power generation capacity are forced to operate at low voltage.
On the other hand, the MPPT charge controller track the solar panel voltage and current in real-time & ensures that the solar array delivered the maximum to the solar battery. It draws maximum power from the solar arrays and then works as a modulator that varies its output voltage to match that of the battery. In case, the voltage needs to be stepped down, the current outflow is increased to ensure maximum power output and faster battery charging.
The Features & Warranty of The Solar Inverter:
The price of a solar inverter also depends on what features are available in it. The solar inverter with smart technology will always have more price than the solar inverter with basic functionality. Along with this, the inverter’s warranty factor also affects its price. Features like LED screens, advanced safety features, internet communication & wireless connection, etc. drive up the cost.
