While solar modules were 10–11 A in the past, latest innovations with bigger wafers produce between 15 and 18 A current. Many inverters on the market are limited to under 15 A (Impp). The Solarnative Power Stick is designed for an MPP current of up to 20 A by default, making it compatible with M10 or G12 wafers. Whatever type of modules you are planning to install, this micro-inverter can handle it!
To avoid larger module currents, manufacturers are designing new PV module layouts resulting in module voltages from 40 to 60 V. As a consequence, the maximum number of modules in one string drops to 14, due to typical string systems’ limitation of 1,000 V. Many optimizers and micro-inverters are not designed to process the higher module voltage. But guess what? With up to 67 V, the Solarnative Power Stick is!
While a stronger current results in higher energy losses on the DC side, the Solarnative Smart Energy Home does not face this problem. Converting the module’s DC power into AC power right at the source, the system spares long and inefficient DC cables.
