Welcome to Guangzhou HanFong New Energy Technology Co., Ltd
Many customers advice on the art solar inverters power problems, usually ask for a more power is enough to use. But here we need to make different demands on different judgments.
First, we need to know your system is a grid or off-grid. If the grid, the system of solar power inverter total power demand only a little larger than the solar cell module can be connected to the total power; if it is off-grid, the solar system's inverter power needs according to the load is determined.
Second, determine the type of your system, we need to know your total power load and the composition (here for the off-grid system, grid system needs to know the total power of the solar panels can be). For the average load, load power to meet more than just use; If the load has inductive loads, such as refrigerators, televisions, air conditioners, etc., you need to consider its starting power, due to the inductive load current at startup is usually 3 minus four times, then the power inverter maximum power that must be met, otherwise it can not start the load, then the power of the PV inverter will be 3-4 times the total power load.
Finally, we must consider the efficiency. General formal vendor will be marked on the identification efficiency, solar inverter efficiency of 60-90% has, the higher the efficiency of the higher energy efficiency, of course, the more expensive price, to be determined according to their own situation.
There is a particular need to pay attention, general inverter manufacturers say the power of the visual power, for example, they say 1KW actually 1KVA, equivalent to 800w, the user at the time of purchase must be aware of this.
