3.3 Avoid expensive main panel upgrades <br />The size of the PV and energy storage breakers permitted to be installed at a house may be limited by <br />the NEC based on the size of the main panel and utility service rating. Installers may not be aware of <br />such limits until late into the project. As a result, the system size sold to the homeowner may need an <br />unplanned main panel upgrade, which adds significant labor and hardware costs to the project. The <br />PCS-certified Enphase Power Control features, MPU avoidance with Busbar Overload Control and <br />with Feeder Control, enable large PV and battery systems to be installed while complying with NEC <br />code (NEC 2020 705.13 and NEC 2020 705.12, respectively). <br />This enables installers to avoid the cost and time due to an unplanned main panel upgrade. Enphase <br />Power Control uses real‑time current sensing to monitor and limit the current back-fed into the main <br />panel. <br />3.4 Benefit from longer backup time with high-power batteries <br />The Enphase Power Control feature, IQ Battery over-subscription mode, enables up to twice as many <br />batteries per site compared to systems without the Power Control System enabled. The total number <br />of batteries supported by IQ Combiner 6C, with and without the IQ Battery over-subscription feature, <br />is listed in the following table. <br />Table 1: Maximum continuous current, aggregate power, and aggregate energy comparison with and without the IQ Battery <br />over-subscription <br />Without IQ Battery over-subscription With IQ Battery over-subscription <br />IQ <br /> <br />C <br />o <br />m <br />b <br />i <br />n <br />e <br />r <br />Ma <br />x <br />. <br /> <br />a <br />l <br />l <br />o <br />w <br />e <br />d <br /> <br />I <br />Q <br /> <br />B <br />a <br />t <br />t <br />e <br />r <br />y <br /> <br />1 <br />0 <br />C <br /> <br />u <br />n <br />i <br />t <br />s <br />Ma <br />x <br />. <br /> <br />c <br />o <br />n <br />t <br />i <br />n <br />u <br />o <br />u <br />s <br /> <br />o <br />u <br />t <br />p <br />u <br />t <br /> <br />c <br />u <br />r <br />r <br />e <br />n <br />t <br /> <br />p <br />e <br />r <br /> <br />b <br />a <br />t <br />t <br />e <br />r <br />y <br /> <br />( <br />A <br />) <br />Ag <br />g <br />r <br />e <br />g <br />a <br />t <br />e <br /> <br />p <br />o <br />w <br />e <br />r <br /> <br />f <br />r <br />o <br />m <br /> <br />b <br />a <br />t <br />t <br />e <br />r <br />i <br />e <br />s <br /> <br />( <br />k <br />W <br />) <br />Ag <br />g <br />r <br />e <br />g <br />a <br />t <br />e <br /> <br />e <br />n <br />e <br />r <br />g <br />y <br /> <br />s <br />t <br />o <br />r <br />a <br />g <br />e <br /> <br />c <br />a <br />p <br />a <br />c <br />i <br />t <br />y <br /> <br />o <br />f <br /> <br />b <br />a <br />t <br />t <br />e <br />r <br />i <br />e <br />s <br /> <br />( <br />k <br />W <br />h <br />) <br />Ma <br />x <br />. <br /> <br />a <br />l <br />l <br />o <br />w <br />e <br />d <br /> <br />I <br />Q <br /> <br />B <br />a <br />t <br />t <br />e <br />r <br />y <br /> <br />1 <br />0 <br />C <br /> <br />u <br />n <br />i <br />t <br />s <br />Ma <br />x <br />. <br /> <br />c <br />o <br />n <br />t <br />i <br />n <br />u <br />o <br />u <br />s <br /> <br />o <br />u <br />t <br />p <br />u <br />t <br /> <br />c <br />u <br />r <br />r <br />e <br />n <br />t <br /> <br />p <br />e <br />r <br /> <br />b <br />a <br />t <br />t <br />e <br />r <br />y <br /> <br />( <br />A <br />) <br />Ag <br />g <br />r <br />e <br />g <br />a <br />t <br />e <br /> <br />p <br />o <br />w <br />e <br />r <br /> <br />f <br />r <br />o <br />m <br /> <br />t <br />h <br />e <br /> <br />b <br />a <br />t <br />t <br />e <br />r <br />i <br />e <br />s <br /> <br />( <br />k <br />W <br />) <br />Ag <br />g <br />r <br />e <br />g <br />a <br />t <br />e <br /> <br />e <br />n <br />e <br />r <br />g <br />y <br /> <br />s <br />t <br />o <br />r <br />a <br />g <br />e <br /> <br />c <br />a <br />p <br />a <br />c <br />i <br />t <br />y <br /> <br />o <br />f <br /> <br />b <br />a <br />t <br />t <br />e <br />r <br />i <br />e <br />s <br /> <br />( <br />k <br />W <br />h <br />) <br />IQ Combiner <br />6C (X-IQ-4 29.5 28.32 40 8 16 30.72 80 <br />Benefits of Enphase Power Control <br />9 © 2025 Enphase Energy Inc.

The aggregate power export limit feature measures the aggregate power <br />across all the phases being exported and limits the PV production and battery power (if present), <br />to ensure that the power export at the location of the IQ Meter Collar with integrated consumption <br />metering or the installed consumption current transformers (point of current measurement) does not <br />exceed the limit specified by the installer in the Enphase Installer App. <br />3.6 Expand systems in California with NEM multi-tariff <br />In California, expanding a PV system by more than 10% of the existing nameplate capacity or 1 kW <br />(whichever is smaller) requires a new interconnection application and a transition from the existing <br />NEM 1 or NEM 2 tariffs to NEM 3—also known as the Net Billing Tariff (NBT). <br />NEM multi-tariff is an interconnection option offered by all three major California utilities (PG&E, <br />SDG&E, and SCE). By using the certified NEM Integrity Mode feature under UL 3741 v2, homeowners <br />can expand existing systems without losing their current tariff structure.
