A: When using double-sided modules, pay attention to the following when choosing an inverter:
One is not to overmatch, because bifacial modules can sometimes increase power generation by 20% to 30%, that is to say, increase output power. It is recommended that modules and inverters be configured at 0.9:1.
Second, when the power of the module increases, only the current can increase, but the voltage will not increase. Therefore, it is necessary to choose an inverter whose input string current is greater than 12A.
