When it comes to evaluating your solar system equipment, solar panels aren’t the only thing to consider. In a solar system, solar power inverters play an equally vital role: they convert the electricity generated by your solar panels into a form that can be used by your appliances, lighting, and other gadgets. The solar inverter prices vary from model to model.
What Is the Purpose of a Solar Inverter? In A PV System, How Do Solar Inverters Work?
When the sun shines on your solar photovoltaic (PV) system, electrons in the solar cells begin to travel, generating direct current (DC) electricity. Circuits collect the energy within the cells, which you can utilize in your home. This is where your solar inverter enters the picture. Because most homes run on alternating current (AC) rather than direct current (DC), the energy generated by your solar panels isn’t useful on its own. When your solar panels absorb sunlight and convert it to energy, the DC energy is transmitted to the inverter, converting it to AC electricity. Always compare solar inverter prices before you purchase one.
How to Choose the Most Appropriate Inverter for Your Home
After you’ve learned how solar inverters function, you’ll need to figure out which type is appropriate for your solar PV system. String inverters aren’t ideal for every system, and paying extra for optimizers or microinverters isn’t always essential. In the end, there is no universally correct or incorrect response, only what is appropriate for your specific circumstances and needs. Solar inverter prices will be higher for inverters that are more efficient and provide an extended backup period.
There are three types of solar inverters:
Stand-Alone/Off-Grid Inverters- Off-grid inverter system consists of a solar inverter, solar panel and solar battery. Solar inverter stores the DC power generated by solar panels in solar batteries and converts into AC power to run the home appliances. This system is recommended for areas where there is no electricity available or have longer power cuts.
Grid-Tied Inverter — Its phase corresponds to that of the utility supply. On-grid systems consists of only a grid tie inverter and solar panels. They do not come with battery bank and you can export excess power generated by solar panels to utility supply. It is connected to the utility grid and is disconnected if it detects that the grid is not present for safety measures. For example, if there is a power outage, it will shut off automatically.
Hybrid Inverter- A hybrid inverter is a combination of an on-grid and off-grid solar inverter. These are more versatile but expensive than on-grid and off-grid inverters. It can easily work without a grid, store electricity to batteries as well as export the excess electricity to the grid. Solar inverter prices for all these inverters will be different. You can choose one that suits your budget the most.
How Can You Pick the Best Solar Inverter for Home?
There are several sizes, brands, and models and solar inverter prices to choose from. Choosing the proper solar inverter from this list necessitates a basic understanding of the concepts. The following are some of the most important variables to consider:
(This can be certified for safety by an independent testing laboratory.)
- Watts: When a device is turned on, it consumes a certain amount of power. The Watt is a unit of energy that is measured in joules per second. Watts is calculated by multiplying Voltage (V) and Current (A). For example, if the voltage is 110V and current is 3A, then you multiply 3 by 110 to get 330W (watts).
- Watt-hours: It’s the multiplication of the device’s wattage and the number of hours it was in use. When a 100-watt bulb is used for 10 hours, 1000 watt-hours are consumed.
- Efficiency is defined as the proportion of output power to input power. 100% efficiency is difficult to obtain as heat causes some electricity to be lost. The load determines the efficiency of a solar inverter, and an efficiency graph is included in the inverter’s specifications. It’s the efficiency versus load graph.
- Internal protection: The components of the solar inverter must be protected from overload, lightning surges, and other hazards. It must have sensing circuitry to detect faults and shut off automatically. It must turn off if the supply voltage is too low. Otherwise, the battery will be overcharged and may be destroyed.
We are sure that if you look out for the specifications mentioned above and choose a manufacturer that provides you extended warranty and guarantee periods you will be able to purchase the best solar inverter. Luminous offer off-grid and on-grid solar inverters. The NXG+ is an off grid solar inverter that can charge from both the grid and the sun. In the absence of solar, the NXG+ Inverter will charge the batteries from the grid. They offer the most competitive solar inverter prices. Check out their website and explore more options.
