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 [...]

Would you choose pure sine wave or modified sine wave inverter? Which one is better?

Would you choose pure sine wave or modified sine wave inverter? Which one is better? Pure sine wave inverter or modified sine wave inverter, which one is better? If it’s used for an ordinary load in your house, you can choose either pattern of them, because most operating of devices do not has vast discrepancy when it runs. To give you a better understanding of their usage, here’s how they differ: A pure sine wave inverter is a electronic power device that [...]

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 [...]

How long do solar generators last?

How long do solar generators last? The solar generators life time is affected by how you use it. Normally it can generate electricity for 20 years ~ 25 years. Solar panels are very durable and capable of withstanding snow, wind and hail. The other components of the solar generators will need to be replaced at different times according to your usage condition. Xindun Power focus on one-stop service of solar generators sales, solution configuration, production, installation guidance, and after-sales maintenance, We have [...]

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 [...]

What size solar energy system I should get?

What size solar energy system I should get? This is Xindun Power — solar energy system solution expert in China, is explaining to you “What size solar energy system I should get? ” The size of solar energy system will depend on how much electricity you use everyday, the type of appliances or tools and the weather condition where you live. Usually, solar inverter power should be 1.2~1.5 times the load power if you don’t have strong impact loads, solar panels power [...]

How to choose the battery,lead acid or Lithium iron Phosphate?

How to choose the battery,lead acid or Lithium iron Phosphate? In the configurations of solar systems, batteries make up a big part of it. But many people find it difficult to choose which kind of batteries suitable for them.Let’s compare the two most use battery first. Lead acid battery There are a lot of kinds for lead acid battery, but we mostly sell AGM type sealed lead acid battery,which price is competitive and quality good. This is battery is maintenance-free, is a [...]
