24v pure sine wave inverter output is the same as the grid

24v pure sine wave inverter output is the same as the grid we use every day even better sine wave AC, because it does not exist power of electromagnetic pollution. 24v inverter work itself but also consume some power, therefore, its input power greater than its output power. Efficiency of the inverter that is inverter output power and input power ratio. The world Solar power inverters, high efficiency in Europe and America, the European standard is 97.2%, but the price is more expensive, domestic solar PV inverter efficiency market almost 90% or less, in addition to the choice of efficiency inverter, waveform It is also very important.
