How to Find the Best Solar Inverter
When shopping for a solar inverter, you need to consider factors such as size, type, efficiency, price, and warranty. We break down what you need to know and pay attention to.
Solar Inverter Dimensions
The best inverter size for your system depends largely on the power requirements of the equipment you plan to run. Be aware that you may be operating more than one unit at any given time - make sure the continuous rating is high enough to handle this. Your inverter must also be able to handle surges from many loads starting at the same time.
To determine the size you need, you should calculate the total wattage you may need at any one time. Then, choose an inverter with slightly higher output power.
An inverter is sized by its maximum continuous output in watts. Again, make sure the inverter is rated for more than the combined wattage of all the AC loads you plan to run at the same time.
Most appliances have some sort of label or owner's manual that should tell you their wattage, but here's a formula to convert AC amps to watts (if you only know amps):
AC Amps X 120 Volts = Watts

Solar Inverter Prices
Inverter with String: The cost of a solar inverter is determined by its size and brand. String inverters can range in price from $1,000 to over $2,000.
Microinverter: Microinverter solar inverter cost mainly depends on the number of panels in the system and their rated output. A microinverter will set you back about $300. According to popular estimates, systems with microinverters are expected to cost approximately 20% more than systems with string inverters.
Optimizer: An optimizer is similar to a microinverter but cheaper. On the other hand, adding an optimizer for the few panels that really need one might only cost a few hundred dollars.
Hybrid inverters: Hybrid inverters cost between $1,000 and $2,000, with many variants priced at $3,000 or more.
Battery Inverter: If the battery requires a separate battery inverter, this typically adds $2,000 to $3,000 to the total cost of the installation.
Our investigation found that by early 2022, the average cost of a solar inverter will be about $0.28 per watt, with prices ranging from $0.49 to $0.10. Inverters typically account for around 6.13% of the total installed cost, with an average cost of $0.29 per watt and an average installed cost of $3.73 per watt.
Solar Inverter Efficiency
Conversion efficiency varies by brand, but most good inverters are around 97% to 99% efficient, so energy loss is relatively small. That said, shading and other factors can have an impact on energy system efficiency, and your PV inverter plays a role in minimizing these losses.
We have a professional team to ensure that the efficiency of our solar inverters will not be lower than 97.5%.
Solar Inverter Warranty
Solar power is a major investment, so it's important to understand how your solar inverter warranty works.
product quality assurance
Product warranties cover physical defects or manufacturing defects. Most solar inverter brands offer at least a 10-year product warranty, while some reputable brands offer 20 to 25 years.
A Performance Warranty guarantees that your solar inverter will continue to produce close to its expected output throughout the warranty period. Regardless of brand or wattage, the output will decrease over time, but typically no more than 10% to 20% loss over 25 years.
Frequently Asked Questions About Solar Inverters
We thought it would be useful to provide our customers and visitors with a comprehensive list of frequently asked questions about inverters. If you have other questions, please contact us.
1.what is Three-Phase Solar Inverter？
It converts DC power generated by solar panels into AC electricity just like any inverter. However, a three-phase solar inverter does something extra, which is, it splits the AC into 3 chunks for a three-phase supply.
2.What is a single inverter？
A single-phase inverter is a DC-to-AC inverter that converts DC input power into single-phase AC output power at the desired voltage and frequency.
3.What is a hybrid inverter？
A hybrid inverter is a type of smart inverter that can store excess solar energy in a battery system for its own use. Hybrid inverters function like normal grid-connected solar inverters, but can typically operate in one of a number of different modes depending on the application. This includes battery backup mode, which provides a limited level of backup power in the event of a blackout
4.How the solar inverter works
A solar inverter works by taking a variable direct current or "DC" output from a solar panel and converting it to an alternating 120V/240V current or "AC" output. The appliances in your home run on AC instead of DC, which is why a solar inverter must change the DC output collected by the solar panels.
5.Types of Solar Inverters
There are three main types of solar inverters – string inverters, micro inverters, and power optimizers.
6.Solar Inverter Installation, Storage Instructions
(1) Pack inspection
1.1 Open the package of the device, please check the product accessories, including: one host, one user manual.
1.2 Check whether the device is damaged during transportation. If any damage or accessories are found missing, please do not turn on the device and inform the carrier and dealer.
(2) Precautions for installation and storage
2.1 The installation of equipment should be operated by professionals or assisted by local dealers.
2.2 When transporting the equipment, appropriate protective measures need to be taken; when the equipment is moved from a low-temperature environment to a high-temperature environment, water droplets may appear, and it must be completely dry before use to ensure safety.
2.3 Do not expose the equipment to harsh environments such as moisture, flammable and explosive, or a large amount of dust accumulation; do not cover or block the ventilation openings, and reserve an air circulation gap of more than 10CM around the equipment; in order to have good heat dissipation;
2.4 When the device is not connected to the mains and is not in use for a long time, the battery switch must be turned off;
7.How to maintain and maintain solar inverters？
(1) Solar inverter products require little maintenance, and the battery only needs to be charged frequently to obtain the expected life.
(2) If the device is not used for a long time, it is recommended to charge it every 4-6 months. Under normal circumstances, the service life of the battery is 3-5 years. If it is found to be in poor condition, it must be replaced in advance. When replacing the battery, it must be performed by professionals. Batteries should not be replaced individually, and the instructions of the battery supplier should be followed for overall replacement.
(3) Before replacing the battery, the equipment must be turned off, disconnected from the mains, and turn off the battery switch. Remove metal objects such as rings and watches.
(4) When connecting battery cables, it is normal for small sparks to appear at the joints, which will not cause harm to personal safety or equipment. Do not short-circuit or reverse the positive and negative poles of the battery.
8.Judgment and treatment of simple faults of solar inverters
Warning :High voltage inside the device! Do not open it by yourself, or try to do maintenance, so as not to be in danger!

9.what solar inverter do i need
As a general rule of thumb, you need to match your solar panel wattage. So if you have a 3000 watt solar panel system, you need at least a 3000 watt inverter.
