Product Details
Technical Features:
1. High frequency switching technology
2. Multiple protection technology
3. MPPT control technology
4. Battery management technology
Working modes:
Regular Mode：When there is electricity power，the AC charging function is always maintained.If the system is equipped with a solar charge controller，the PV isalways charged，andthe solar energy is charged simultaneously with the electricity power；
Energy Storage Prlority Mode：
When there is solar energy and electricity power are provided，electricity input is off，solar charging and inverter output.When there is few sunlight，charged by electricity and stabilized voltage output；
lf the solar energy and electricity power are concurrent interruption，inverter output.
Energy saving mode：
When there is no output load，inverter closed，there is no output，reduce loss，when the output load，inverter out put normally.

what is Low Frequency solar power inverter?
Low-frequency inverters have the advantage over high-frequency inverters in two fields: peak power capacity, and reliability. Low-frequency inverters are designed to deal with higher power spikes for longer periods of time than high-frequency inverters. Power spikes can occur for a number of reasons (e.g. devices like power tools, pumps, vacuum cleaners and other appliances with electric motors require high starting power); when inverters experience such spikes, they can endure the increased power for a short period of time before shutting down in order to prevent any damage being done to them. Low-frequency inverters have much greater peak power capacity to handle large loads with power spikes than high-frequency inverters. In fact, low-frequency inverters can operate at the peak power level which is up to 300% of their nominal power level for several seconds, while high-frequency inverters can operate at 200% power level for a small fraction of a second. The second main difference is reliability: low-frequency inverters operate using powerful transformers, which are more reliable and sturdy than the high-frequency inverter’s MOSFETs, which use electronic switching and more prone to damage, particularly at high power levels.
What is the difference between high frequency and low frequency inverter?
Depend on your loads, and the place you install the inverter. the efficiency, high frequency is higher than the low frequency inverter. peak power, high frequency inverter is 2 time of rated power. but the low frequency inverter is 3 times of rated power.
What type of transformer is used in a solar inverter?
The low frequency inverters discussed in previous threads use a ferro-resonant transformer to low pass filter a square wave output switching at 60 Hz. I am familiar with ferroresonant transformers having used them in industrial applications since the 80’s. In particular I spec’ed Sola MCR power conditioners as part of any process control system I worked on back in the 90’s when that was my day job.
Are Ouyad inverters any good?
Yes, they are useful if you follow the installation and maintenance instructions. Nevertheless, it is a reliable brand for a home solar inverter solution. For other options, you can check out the featured products highlighted earlier.
Do low frequency inverters come with power sockets?
In addition, in most cases low frequency inverters do not include mains power sockets – they come with terminals where AC wires should be connected which then connect to mains sockets.
How to use & install?
You can refer to the installation or user manual that comes with the inverter you have chosen. In most cases, you can easily set up the system because many of them are meant for DIY solar systems.
Are low frequency inverters obsolete?
Technically ouyad’s inverter is a high/low frequency design.that is it uses high frequency electronics to drive a low frequency transformer. True low frequency inverters are obsolete, they did the switching at 60 hz. Most if not all “low frequency” inverters are really “high/low” frequency designs.

What are the most trusted solar inverter brands?
The most trusted brands ouyad solar are industry leaders that consider user-friendliness, innovation, and durability in their products. They also design inverters with robust features and made of quality products.
What is a grid tie inverter?
An on grid inverter or a grid tie inverter works by converting the direct current into alternating current. It is suitable for use and injection into an electric power grid or system. One is used between electrical generators, including wind turbine, the grid, solar panel, or hydroelectric. It also works by testing the solar panel output, too.
How long do solar inverters last?
When reading a grid tie inverter review, you might have bumped into this question. Many of them have a lifespan of reaching ten years. But for some, they can last for at least 20 years.

How long do solar inverters last?
These devices work for at least ten years and the others at least 20 years. Nevertheless, quality inverters have a long lifespan, so nothing to worry about them failing after a few uses.
How to use & install?
You can refer to the installation or user manual that comes with the inverter you have chosen. In most cases, you can easily set up the system because many of them are meant for DIY solar systems.
How to care & clean?
Once installed, these devices do not require any maintenance at all. From time to time, you can just check it to ensure its working optimally. Some of these also come with automatic functions for lesser effort on your part in terms of keeping it working optimally.
