What is the maximum continuous current allowed for Enphase Energy System?

The maximum allowed continuous current from both the PV systems is 32 A. If the third-party PV system supplies a maximum continuous current of 16 A, then the installer can manually set the maximum continuous current for Enphase Energy System to 16 A, that is, 32 A−16 A using the Current Limit Directly Entered parameter in EIA.

What happens if a system configuration exceeds the NEC 120% rule?

If the installer enters a system configuration such that the total current in the system due to reactive power will exceed the limit to which the export current needs to be curtailed based on the NEC 120% rule, the installer will see a pop-up such as the one mentioned in the following Figure 21. and proceed.

How do I control ess without grid meter setting?

See the Settings → ESS → Control without grid-meter setting. 2. Systems with a canbus-connected lithium system: when the GX device is no longer receiving information from the battery, via the CAN-bus. 3. When charging the battery is not allowed (BMS max charge current = 0A, or max charge power = 0W) and there is excess PV power.

What happens if a kWh is fed back to the grid?

Every kWh fed-back to the grid is erroneously counted as energy used, and will be charged for. Feed-in Feed-in of PV power via an MPPT Solar Charger can be enabled or disabled in the Energy Storage Systems menu on the CCGX. Note that when disabled, the PV power will still be available to power AC loads.

What is aggregate power export Limit Mode?

Aggregate power export limit mode: This feature ensures that the aggregate power exported to the grid is limited to the Aggregate Power Export Limit (PEL) defined by the installer. Figure 1 provides a birds-eye view of the point of current being measured and limited using Enphase Power Control for each feature.

How is battery size calculated in a backup system?

In a backup system, the battery size is calculated by the required autonomy during a mains failure. See AC-Coupling minimum battery capacity for minimum battery sizes of systems with a grid-tie PV Inverter connected on the AC output of the Multi(s) or Quattro(s).
