National Electrical Code compliance
As per NEC section 690.11, this requirement is for direct current (DC) Arc-Fault circuit protection that only applies to systems with DC voltages above 80 VDC. This requirement is not applicable to Enphase
4 FAQs about Microinverter Requirements
What are the requirements for a solar inverter system?
There are two main requirements for solar inverter systems: harvest available energy from the PV panel and inject a sinusoidal current into the grid in phase with the grid voltage. In order to harvest the energy out of the PV panel, a Maximum Power Point Tracking (MPPT) algorithm is required.
What factors should you consider when choosing a microinverter?
When comparing your microinverter options, there are a few main factors to keep in mind: Just like solar panels, microinverters have varying efficiencies. An inverter's efficiency measures energy losses during the conversion from DC to AC electricity. The more efficient the microinverter, the more solar electricity production.
What are the key features of microinverters?
Key features of microinverters Individual panel optimisation: Each microinverter operates independently, maximising the output of its corresponding solar panel. Modular design: Microinverters enable easy system expansion, allowing additional solar panels to be added without significant redesign.
Do microinverters meet NEC requirements?
The microinverter and cable connectors, as part of the product listing, meet the requirements of the NEC. Section 690.15 requires that inverters (including microinverters) include disconnects from all sources of power and that the disconnecting means are grouped at or within sight of the inverter.
