NO REGULAR REPLACEMENTS
String inverters need to be replaced every 10 to 15 years, adding cost and the inefficiency of maintenance to solar systems that use them. Microinverters from Enphase are tested for 20 years of performance, something string inverters don’t have. If you’re looking for a low-maintenance solar product, microinverters may be the way to go.
SAFER LOW VOLTAGE
Microinverters convert DC to AC at the module, which is safer for workers and homeowners. Solar modules can generate a voltage of as high as 1,000 V on a roof whereas a micro-inverter lowers that to 60 V and is in the safer AC. Depending on the value homeowners put on safety, microinverters may be an attractive option for their roofs.
NO SINGLE POINT OF FAILURE
A micro-inverter failure will stop the production of electricity from the panel it is fitted to, whereas a string inverter failure will stop the entire string, resulting in a more significant or complete loss of electrical supply.
