How does an off grid power system works?

How does an off grid power system works? Many people are planning to reduce their household electricity bills, especially with the widespread use of renewable energy in residential and private villa in recent years. How could you not be impressed and moved when you walk pass your neighbor’s house and see that their roof has fitted with excellent solar panels? Compared with grid connected power system, the off grid power system is more capable of self-sufficient power supply. No matter in...

What is the difference between on-grid(grid-tied) solar system and off-grid solar system?

What is the difference between on-grid(grid-tied) solar system and off-grid solar system? The simple answer to this is that on-grid solar systems can send the electrical power generated by the PV to the utility power grid while the off-grid solar systems can not. 1.On-grid (grid-tied) solar system The main components for on-grid system includes solar panel,solar charge controlller and on-grid inverter,but without battery. In the on-grid solar system,the electrial power generated by the solar panels will send the the grid power directly through...

How to ensure your solar power station not be affected by the weather?

How to ensure your solar power station not be affected by the weather? How can we ensure that solar power station is stable and not affected by the weather? First of all, the solar panels installation orientation should be southward, so that it can fully receive the sun's illumination. The installation angle is theoretically calculated according to the local latitude and longitude, and the arrangement and spacing need to be combined with the local sunshine and the size of the roof structure. If the...

Which is better? A “low frequency” or “high frequency” inverter?

Which is better? A “low frequency” inverter or “high frequency” inverter? Advantages for low frequency: 1.Peak power capacity: low frequency inverters can operate at the peak power level which is up to 300% of their nominal power level for several seconds, suitable for inductive loads, while high-frequency inverters are more easy to burn out when driving inductive loads. 2.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...
