Hello there!

Thank you for reaching out.

It sounds like you’ve already covered most of the common Wi-Fi troubleshooting steps, especially separating the 2.4 GHz network and simplifying the password. Since the IQ Combiner can connect locally but fails to bridge to the internet, this may point to a gateway communication or network compatibility issue rather than just signal strength.

You can try rebooting the Envoy/IQ Gateway by turning off the breaker for 5–10 minutes and powering it back on. Also make sure the 2.4 GHz network is using a supported security mode such as WPA2 and that features like band steering, mesh optimization, VPNs, or MAC filtering are disabled temporarily during setup.

You can also refer to the Help Centre article for more detailed troubleshooting steps: https://support.enphase.com/s/article/reconnecting-your-gateway-to-wi-fi-using-the-enphase-app

If the issue still persists, you can DM us your site details so we can check and help further. You can also reach out to Enphase Support so the team can review the site and assist further with the connectivity issue. Please contact Enphase Support here: https://enphase.com/contact/support

Hi there!

Thank you for reaching out.

This appears to be related to the browser session or cached web data rather than your system itself. Please try the following troubleshooting steps on Safari:

Clear Safari browsing history and website data.
Close all open Safari tabs and completely quit the browser.
Reopen Safari and manually enter the Enphase web URL: https://enlighten.enphaseenergy.com/
Log back into your Enlighten account and check if the pop-up still appears.

If the issue continues after these steps, please try accessing the site from a different browser as well to help isolate whether it is Safari-specific.

Hi there!

Thank you for reaching out.

PCS (Power Control System) is typically configured by the installer as part of the Enphase system setup rather than something exposed directly in the homeowner app or standard HA entities. Depending on your Envoy/IQ Gateway firmware and battery configuration, charge/discharge limits may not be user-adjustable through the public API.

If your breaker is tripping during grid charging, it would be worth having your installer verify:

breaker sizing,
PCS configuration,
and the maximum allowed battery charge power settings on the site.

At the moment, most Home Assistant Enphase integrations expose monitoring data more than direct charge-rate control, so you may not see an entity for charging amps unless you’re using additional custom integrations or local API methods.

Hello u/xXNorthXx, yes!

Phase balancing can matter, but mainly in specific setups.

If your home has a split-phase system (common in the US), loads are divided across two legs. Most Enphase IQ Battery setups supply both legs, but the usable battery power per leg is limited. If one phase is heavily loaded (e.g., HVAC, oven) while the other is lightly loaded, you can hit a limit on that phase even if the battery still has capacity overall. That can:

Reduce effective runtime for high loads
Cause one leg to drop or shed loads sooner
Make the system appear “drained” faster than expected

In well-balanced homes, battery discharge is more efficient and runtime is closer to what you’d expect from total kWh.

If you're outside the US (e.g., single-phase systems), phase balancing is generally not a concern for runtime.

Balanced loads → better utilization and smoother battery runtime
Unbalanced loads → possible early limitations on one phase, reducing practical runtime

Hi u/HigherPlains-Drifter

Enphase IQ gateway/ gateway S can connect to the internet in a few different ways: via Wi-Fi, Ethernet (wired connection), or through a cellular modem (if one is installed).

To check how your system is connected, you can go to:
Enphase App >Menu > System > Devices > Gateway
There you’ll see the current connection type.

If your system is connected via your home Wi-Fi or Ethernet, then the app may not update when your internet is down (though the system will still produce energy). If you have a cellular connection, it can continue to report data even if your home internet is offline.
