System Monitors & Displays

System monitors and displays show solar production, loads, and battery state of charge at a glance. Many hybrid and microinverter systems use a brand-specific controller or envoy-style gateway with a local display or app.

Match the monitor to your inverter platform (for example Enphase IQ Envoy / System Controller, or battery-brand energy management). Need help choosing? Call 877-878-4060.

What are system monitors & displays?

This leaf is for the hardware that lets you see and manage system status — production, consumption, battery SOC, and backup/transfer state — through a local display, energy-management panel, or brand app. It is not where you shop for module-level radios or CT clamps alone.

Envoy vs IQ System Controller vs SimpliPHI EnergyTrak

  • Enphase IQ Envoy — the primary IQ microinverter gateway and system monitor. It gathers production (and consumption, when CTs are installed) and reports to Enlighten. Shop Envoy under Gateways & Communication as well; it also appears here because it is the day-to-day monitoring hub for IQ PV.
  • Enphase IQ System Controller (and Power Kits that include one) — storage / backup / transfer equipment for Ensemble-style systems. It is a controller for backup and loads, not a substitute for the Envoy gateway. Pair System Controller SKUs with the correct Envoy (and CTs when you need consumption metering).
  • Briggs & Stratton SimpliPHI EnergyTrak — energy-management / control for SimpliPHI lithium battery systems. Choose EnergyTrak when your bill of materials is SimpliPHI-centric, not Enphase IQ.

When to shop Gateways vs Sensors vs this leaf

  • System Monitors & Displays (this page) — brand system controllers, energy-management panels, and envoy-style monitors you use to run the system.
  • Gateways & Communication — Envoy, Tigo TAP / Cloud Connect Advanced, COMMS-KIT, and other data/control links between devices and the cloud/app.
  • Sensors & Sending Units — CTs (including Enphase CT-200 for Envoy consumption), temperature sensors, and sending units that improve metering accuracy.
  • Shunts & Battery Monitors — precision battery-bank current / SOC gear when ACTIVE stock is available (often empty; call if you need a shunt-based monitor).

FAQ

Is an IQ System Controller the same as an IQ Envoy?

No. The Envoy is the IQ monitoring / communications gateway. The System Controller manages backup, transfer, and storage-side control for Ensemble designs. Most Enphase storage builds need both, per Enphase documentation.

Where do I buy the CT-200 consumption CTs?

Enphase CT-200 split CTs live under Sensors & Sending Units. They work with a compatible Envoy for consumption monitoring — they are not a standalone system display.

Should I start here or in Gateways?

If you need the primary Enphase or Tigo communications gateway, start in Gateways & Communication. If you need a System Controller, Power Kit, or SimpliPHI EnergyTrak panel, stay on this leaf.

Can altE help me pick the right monitor?

Yes. Share your inverter/battery model and whether you need production-only monitoring, consumption CTs, or backup/storage control. Call 877-878-4060.
