Solar power is at the heart of sustainable power generation, providing an efficient, clean alternative to coal-fired plants in providing electricity to homes. Solar inverters are the souls of power generating apparatus, they face the masterstroke duty of changing the straight current (DC) of sun plates into alternating current(AC) in use in homes and businesses. Read on about the significance of Solar Inverters, different types, and some tips on choosing and installing them. From grid-connected, off-grid, or hybrid systems, this post will walk you through the ins and outs of solar inverters to make your solar energy setup more efficient and effective, meeting your power requirements while still saving you money.
This article takes you on a deep dive into solar inverters, starting from fundamental operation principles to a guide for selecting the optimum type for your new solar application.
What is a solar inverter?
Before understanding solar inverters, you must first know the types of current, namely direct current and alternating current. Solar panels produce direct current (DC), and the current only flows in one direction. However, household electricity is alternating current (AC), and current flows in both directions.
Solar inverters are an important component of solar energy systems. Solar panels generate a direct current through the photovoltaic effect. The job of the solar inverter is to convert the direct current generated by the solar panels into alternating current so that your load appliances can operate normally.
How to connect solar inverter to work?
Solar inverters are usually installed in a well-ventilated area and wall-mounted. Pay attention to avoid rainwater causing water to enter the machine, which may cause the machine to not work properly, and it cannot be installed in a place exposed to direct sunlight.
First, combine the DC output wires of the solar panels and connect them to the inverter, which you can install close to the solar panels and away from rain and direct sunlight. The advantages of this installation are that, firstly, being close to the solar panel can reduce the loss of cables. It would be better if this place was close to the distribution box. Secondly, it reduces the negative effects caused by rainy days and direct sunlight.
The solar inverter connects to your distribution box (DB) by converting DC power into AC power. The power generated can supply your load appliances to operate normally. If you install a grid-connected system, the excess power will be calculated according to the metering plan. Sell it back to the grid; if you install an off-grid system, the excess electricity can be stored in the solar cells you are equipped with. Once a power outage occurs, the stored electricity can continue to supply you with normal use, and you will no longer have to worry about The adverse effects of power outages.
Types of Solar Inverters
On grid solar inverter
The grid-connected solar inverter can be connected to the power grid. What distinguishes it from other inverters is that it can sell the excess power generated by the solar panels to the grid after passing through the grid-connected inverter. This can reduce the costs caused by high electricity bills. Reduce the economic burden and achieve cost savings. However, the installation of grid-connected inverter integration needs to be in developed countries or regions with stable power grids.
Off grid Solar Inverter
Off grid solar inverters can work independently from the grid. Its working principle is to store excess power generated by solar panels into solar cells through the action of the controller. At night or in the event of a power outage, the high off grid inverter can convert the power stored in the solar battery into alternating current to ensure your normal power consumption.
This type of inverter is usually suitable for remote rural areas because these places usually have unstable power grids or even no electricity. Therefore, it is not recommended to use off-grid solar inverters in countries and regions with high electricity costs.
Hybrid solar inverter
Hybrid grid solar inverters take into account the advantages of grid-connected inverters and commercial grid inverters. They can connect to the grid and store power through solar cells. The advantage is that the battery is used to store electricity, which can be combined with local electricity rates to maximize electricity cost savings.
However, the cost of configuring a hybrid solar system is higher than on grid solar system and off grid solar system due to the increased cost of batteries.
How to Choose Solar Inverter
Confirm which solar system are you need？On grid, off grid, or hybrid system.
When your local power grid is relatively stable, you can choose the on grid solar inverter solution to configure your solar power system. In the on grid solar power system, the solar panels transmit DC power to the solar inverter, and the inverter converts the DC power into It supplies AC power to load appliances or transmits it to the power grid to realize power recovery.
When your local power grid is unstable or has no power, you can choose off grid solar inverter or hybrid inverter to configure your solar energy system. The DC power generated by the solar panel is transmitted to the solar controller, and the controller will transmit it to the solar inverter according to the set instructions for direct supply or solar battery storage of power to achieve normal power supply in the event of a power outage.
Electricity usage
Choosing the correct solar inverter can determine the power generated by the solar power system by calculating the amount of electricity loaded and the time of use. Usually, these calculations are very complex and can be handed over to the solar power system supplier. They will scientifically configure a stable solar power generation system according to your electricity demand.
Number of solar module
If you already have solar panels and have configured the inverter required for the solar power system, you need to consider the compatibility between the solar panels and the inverter and make sure that its rated input voltage is greater than the voltage of the solar cell.
In addition, the solar inverter you choose needs to be compatible with other solar equipment to avoid wasting your money.
After-sale services
Configuring a solar power system is a complex matter, in which the setting of the solar inverter is very important. Once your solar power system is installed, you’ll be eager to use it to meet your electricity needs. However, if you find that the solar power system is not working properly and the inverter keeps failing, I believe you are devastated. Therefore, it is very important to choose WHC Solar Solution Provider, because they are professional enough and can provide you with complete after-sales service.
Budget
Finally, you must choose a solar power system that fits your budget. It is not recommended that you choose the cheapest solar power system solution because it may cause other after-sales problems or even cause your solar power system to not be used at all.
