In a small off-grid solar system, considering the cost, usually the customer’s battery capacity is not very large and the solar panels equipped are not particularly large. Choosing a good inverter will become very important. If the inverter you choose is a low frequency inverter, then the inverter’ comsumption will drain your batteries, let’s take an example.
2000W low frequency inverter, his static power consumption is usually between 50-100W, we take the middle value of about 75W, then if you do not use any load, the inverter itself loss reaches 0.075wh per hour, which means 10 hours will basically use up a 12V/100AH battery. This is only for static power consumption, if we look at the conversion efficiency, the efficiency of low frequency inverter is between 70-80%, let’s calculate by 75%, then if you need to run 2000W at full load, the consumption of the battery is 2666W, which is very big data, if you have limited solar panels, this will greatly shorten the use time of your off-grid solar system.
The high frequency pure sine wave inverter is perfect for use in small off-grid solar systems, so CNBOU’s BP series pure sine wave inverter has been the first choice of customers. The static power consumption of the BP series 2000W inverter is only 8W, which is only 10% of the low frequency inverter, if the low frequency inverter drain a 12V 100AH battery for 10 hours, then BP2000W will drain a battery of the same capacity for nearly 100 hours. Of course, his conversion efficiency is also very high, 48VDC system, the highest efficiency can reach 94%, even if you are running 2000W at full load, the battery side consumption function is for about 2150W. And the CNBOU BP2000W pure sine wave inverter is usually designed at 110% of full power, allowing customers to run 110% of load occasionally when needed, but not recommended for long term use. We highly recommend our customers to use CNBOU BP2000W pure sine wave inverter, which is also one of the best-selling models in our company.
