What is Solar Inverter

A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.

Benefits of Solar Inverter

Lower or No electricity bills

Solar Inverter systems harness the sun’s energy throughout the day and convert it into electricity that can power appliances at night easily or on cloudy days when it is challenging to receive sun’s energy in its full force. Hence, you save a lot on utility bills as you stop depending on the Grid or traditional and expensive fossil fuels.

Reduced carbon footprint

As solar energy is green and renewable, using it will reduce your carbon footprint. Plus, it emits no harmful gases or pollutants, unlike non-renewable energy which is derived from burning fossil fuels.

All Year efficiency

Solar Inverter systems generate adequate electricity in sunny and on cloudy days too. Moreover, the excess electricity generated gets stored for days when enough solar energy cannot be harnessed due to rain, smog or fog. Hence, the solar panel cost you will bear for all-year efficiency is quite reasonable.

Low Running Cost

Unlike DG Sets, Inverters produce only the required amount of power, increasing the backup time and minimizing the use of battery.

No Pollution

Compared to generators, High Capacity Inverters are completely non-polluting and can be comfortably placed in any working environment.

Safe for Sensitive Equipment

Inverters produce pure power that is equivalent to power supplied by Grid and makes it completely safe to run even the most sensitive electronic equipment.

Types of Solar Inverter

Stand-alone inverters

Used in stand-alone power systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral battery chargers to replenish the battery from an AC source when available. Normally these do not interface in any way with the utility grid, and as such are not required to have anti-islanding protection.

Grid-tie inverters

Which match phase with a utility-supplied sine wave. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages.

Battery backup inverters

Battery backup inverters are special inverters which are designed to draw energy from a battery, manage the battery charge via an onboard charger, and export excess energy to the utility grid. These inverters are capable of supplying AC energy to selected loads during a utility outage, and are required to have anti-islanding protection.[clarification needed]

Intelligent hybrid inverters

Intelligent hybrid inverters manage photovoltaic array, battery storage and utility grid, which are all coupled directly to the unit. These modern all-in-one systems are usually highly versatile and can be used for grid-tie, stand-alone or backup applications but their primary function is self-consumption with the use of storage.

Communicating with Utility Grid

In the event of a momentary power loss, solar inverters make sure that electricity is not transferred from your panels to the external power lines. This will ensure the safety of any line workers who may be maintaining or inspecting the grid.

Easy Detection of Fault

Under emergency situations, the solar power inverter will immediately recognise the issue and shut down, safeguarding the remainder of the system and warning you that service is required before any additional harm happens.

Components of Solar Inverter

Solar panel

Solar panels are the most visible component. It's obvious to know an owner of a solar inverter because you will also see the panel hanging out somewhere on their roof.

Inverters

The inverter is the main machine in the entire system. This is the device that converts the generated energy from the panel and converts it to electrical energy that we can use to power our appliances.

Batteries

Good batteries are the most critical part of a solar inverter. The batteries are used to store energy generated during the day to be used throughout the night when the system is no longer generating power because of the absence of sunlight. This component is developing into a more feasible option for those who primarily use their energy in the evenings. It is also very crucial as it is not expected that a household will run on electricity for the entire day and be in absolute darkness at night.

Charge Controller

The charge controller regulates the rate at which electric current is added to or drawn from electric batteries. It prevents overcharging and may protect against overvoltage, which can reduce battery performance or lifespan and may pose a safety risk.

Maintenance Tips for Solar Inverter

Keep The Inverter Cool

As your inverter changes electricity from DC to AC, it naturally gets hot. To ensure the inverter gets proper airflow, it's recommended you keep at least twelve inches of open space around your equipment.If your inverter has a fan, make sure nothing blocks it or could get sucked up into it. If your fan stops working, the inverter could overheat and lose efficiency.

Keep The Air Intake Filter Clean

Depending on the location of your inverter, the air intake filter can get dirty over time. If the filter accumulates too much dust and debris, it won't be able to cool as well, which affects the inverter's efficiency.
If the filter does get dirty, we recommend that you call a professional to clean the filter instead of doing it yourself, as you may need to take apart some of the equipment.

Check for Error Codes

While you don't need to check your inverter daily, you should check it periodically to make sure everything’s working as expected. This includes looking on the inverter screen for any error codes, or a different light than normal. If anything seems amiss, call a professional to assess the situation.

Use Solar Monitoring Technology

If the manufacturer of your solar power system provides you with technology like a smartphone app to monitor the system, you should use it. This solar tech can provide regular updates about the status of your solar panels and inverter, and give you prompt access to customer service and technicians if needed.

Regular Inspection

Begin by visually inspecting your solar inverter. Look for any indications of physical damage, loose wires, or abnormal signs of wear and tear. Ensure that the inverter is clean and free from debris. Over time, dust, and dirt can accumulate and impact its performance. If necessary, gently clean it using a soft brush or cloth.

Maintain Optimal Temperature

During operation, solar inverters can generate heat. Proper ventilation for the inverter to spread this heat effectively is necessary. Avoid installing it in direct sunlight or near other heat sources, as excessive heat can shorten lifespan.
