The Solar Panel

The module itself — glass, cells and an aluminium frame. The part everybody pictures when they think “solar,” and the part that fails least often.

Specs & why they matter

Typically 400–500 W per module on a residential roof today
Tempered glass over crystalline-silicon cells in an anodised aluminium frame
Power output is normally warranted for 25 years — the longest-lived part of the system
Degrades slowly and predictably, so a sudden drop in production almost never starts here

The Micro-Inverter, Behind the Panel

Turn the module round and there it is: one micro-inverter per panel, tucked up under the top corner of the frame and bolted to the rail by the brackets either side. It converts that panel’s DC to AC right there on the roof.

Specs & why they matter

One micro-inverter per panel, bolted to the rail under the top corner of the frame
IQ8M peaks at 330 VA, IQ8A at 366 VA; 97–97.5% CEC weighted efficiency
Warranted up to 25 years — the longest term on any inverter we service
Grid-forming: paired with an IQ System Controller 2 the array can make power in an outage with no battery at all
Each panel converts on its own, so shade or a fault on one does not drag the rest of the roof down

The IQ Combiner

Every micro-inverter’s AC run lands in here, on its own breaker, and leaves as one circuit. Behind that plain white door is the box we open first on almost every service call.

Specs & why they matter

Every micro-inverter’s AC run lands on its own breaker and leaves as a single circuit
The IQ Combiner carries the IQ Gateway, which is what reports panel-by-panel production
Because the data is per-panel, one dead micro-inverter shows up here as one flat line rather than a vague shortfall

The IQ Battery

Storage for what the array makes and the house does not use yet. A slim silver slab with almost nothing on its face — one status light and a wordmark.

Specs & why they matter

5.0 kWh usable energy per unit
3.84 kW continuous, 7.68 kW peak for 3 seconds
15-year warranty, up to 6,000 cycles
Six grid-forming micro-inverters are built into each battery
Modular — units are added as the load grows rather than sized once at install

The IQ System Controller

The smooth white cabinet next to the battery, and the one that decides what your house does when the grid goes down — islanding the home, running it off the battery, and reconnecting when the utility comes back.

Specs & why they matter

The microgrid interconnect device: what physically and legally separates your house from the grid
UL 1741 listed for grid-forming operation
Without it an Enphase array shuts down in an outage no matter how much sun is on the roof
A deep cabinet rather than a thin panel, which is how you tell it from the battery beside it

6 of 7

The IQ EV Charger

The car charger on the wall, fed from the same solar and battery set. When it is wired into the system properly it can charge from what your roof is making rather than from the grid.

Specs & why they matter

Up to 48 A / 11.5 kW
Talks to the rest of the Enphase system, so the car can be set to charge on surplus solar instead of grid power
Hard-wired on its own circuit — the breaker size, not the charger, usually sets the ceiling
