China High Frequency off-Grid Solar Inverter with Charge Controller

High Frequency Off-Grid Solar Inverter
Descriptions
Ecener is reputable pure sine wave off grid inverter manufacturer in China. Ecener's high frequency off grid pure sine wave inverter is ideal choice for you. The inverter manages power flow of your solar system, converting direct current from solar panels to alternating current needed by your electric appliances, etc.
DC power, say direct current power, is the kind of power generated by solar panels also stored in batteries. However, you cannot use DC power directly to supply electricity to electric appliances for your household use, and you need an inverter to do the job.
AC power, say alternating current power, almost needed by all electric appliances for your home uses. An inverter converts DC power from solar panels or batteries into AC power so you can power your lights, laptop, TV, icebox and other electric appliances.
Why Pure Sine Wave?
Pure sine wave inverter provides "purer" power than modified sine wave inverter. Pure sine wave inverters produce better quality electricity output, almost the same as the Grid and even better.
Modified sine wave inverters produce low quality electricity output: May lead to overheat and breakdown of electric appliances such as well pumps, motors, etc. May damage laptop. Lead to undesired sound on a stereo, affect video and audio quality of TVs.Pure sine wave inverters can avoid all of the above-mentioned issues, that's why we suggest pure sine wave for our clients.

What's the difference between off-grid inverter and on-grid inverter?
An on-grid inverter turns DC power from solar panels into AC power, and sell extra electricity power to the grid for bonus.
It's much easier to connect on-grid inverters with wire because you only need to wire the inverter and solar panels together. Some on-grid solar systems attach batteries on the inverter, but most of them don't have power storage batteries at all.
However, off-grid inverter must have a battery to realize its basic function. Off-grid inverter works like this: the batteries store DC power produced by solar panels first, and the inverter inverts DC power from the batteries into AC power for your household use.
Therefore, off-grid solar systems are more complicated than on-grid solar systems. It needs more job to wire and install off-grid solar systems due to the connection of different parts like solar charge controller, battery monitor and AC and DC circuit breakers.
There are a lot of relevant parts for off-grid solar system such as: battery monitor, surge suppressors, breakers, remote controls, and attachments, etc.
How to choose a suitable Off-Grid Inverter
1. Figure out Inverter Size
You need to figure out the volume of power you need. Just make a sum up of all your lights and electric appliances to calculate how many watts you need.
For instance: Suppose you need 200 watts for energy saving lights, and 500 watts for TV, 600 watts for icebox. In total 1,300 watts. In that case, we'd suggest at least 2,000 watts to leave room for more due to the reason you may need additional electric appliances.
