Actual production varies with location, roof direction, tilt, shading, weather, temperature, equipment, and utility curtailment. Use a site-specific production model before purchase.

System Overview

Each solar module operates with its own Enphase microinverter, converting DC solar power to grid-compatible AC at the module level. This architecture avoids a single central string inverter and provides module-level monitoring and shutdown functionality. The system operates in parallel with the utility grid and is intended to reduce the amount of electricity purchased from the utility while solar is producing.

What Can It Power

What Can It Power?

This 7kW system is a grid-tied, solar-only system. It does not dedicate power to specific appliances. While the grid is available, solar production offsets electrical loads operating in the home and excess production may flow to the utility when permitted by the interconnection agreement.

Daytime Household Loads
  • Refrigeration
  • Lighting
  • Computers & electronics
  • Pool equipment
  • HVAC operation
Flexible Loads
  • Dishwasher
  • Laundry
  • Water heating
  • EV charging
  • Workshop loads
Best Solar Utilization
  • Shift discretionary loads to solar hours
  • Use programmable schedules
  • Coordinate EV charging with production
  • Monitor production in the Enphase App

What Happens During a Grid Outage?

This kit is configured as solar-only grid tie. It is not a backup-power system. During a utility outage, the grid-tied system shuts down as required by its approved grid-interconnection configuration and does not continue powering household loads. Backup operation requires additional compatible Enphase equipment and a different system design.

How Much Energy Will It Produce?

The array is rated at approximately 7kW DC. The Main Listing provides representative annual planning estimates for Phoenix and Chicago. These figures are not guarantees; use a site-specific solar-production model to account for roof orientation, tilt, shading, weather, temperature, equipment, and system losses.

Why This Kit

Why We Chose the Enphase IQ8+ Platform

We selected Enphase IQ8+ for this 7kW kit because it provides a cost-conscious residential grid-tie system using module-level power conversion. Instead of routing the entire array through one central inverter, each module has its own microinverter and can be monitored at the module level.

Platform Advantages
  • Module-level DC-to-AC power conversion
  • Module-level monitoring through the Enphase platform
  • No single central string inverter
  • Enphase power-line communication between system components
  • Advanced grid-support functionality when properly commissioned
  • UL-listed rapid-shutdown functionality when installed per Enphase requirements
  • Purpose-built for 240V Split Phase applications
  • Scalable module-by-module architecture

Built for Solar-Only Grid Tie

This configuration intentionally leaves out battery storage and backup hardware. That keeps the system focused on its primary job: producing solar energy while the utility grid is available and reducing the amount of utility energy the home needs to purchase during solar-production hours.

Expandable Enphase Ecosystem

The IQ8 platform is part of the broader Enphase Energy System. Future battery or backup expansion is possible only with compatible equipment, appropriate system design, and any required electrical/interconnection changes. Battery equipment is not included in this kit.

Is this a battery-backup system?
No. This is a solar-only grid-tied system and does not include battery storage or backup hardware.
Will the system power my home during a utility outage?
No. This grid-tie-only configuration is not designed to provide backup power during a utility outage.
What is the solar array size?
The kit is configured around approximately 7kW DC of solar modules. Panel brand, model, wattage, and quantity are selected from available inventory at purchase, so the final panel count may vary.
Which microinverter does this kit use?
This kit uses Enphase IQ8+ microinverters. One compatible microinverter is supplied for each solar panel selected at purchase, so the final microinverter quantity matches the final panel count.
What grid voltage does it support?
The intended grid architecture is 240V Split Phase. Final compatibility must be confirmed against the exact microinverter SKU and site service.
Does Enphase provide module-level monitoring?
Yes. When the system is commissioned with the IQ Gateway, Enphase provides system and module-level monitoring through its monitoring platform.
Does this system support rapid shutdown?
Enphase IQ8 Series microinverters are listed for PV rapid-shutdown applications when installed in accordance with the applicable Enphase instructions and system requirements.

Potentially, subject to roof space, electrical service capacity, utility interconnection limits, branch-circuit limits, combiner capacity, and current Enphase design requirements.
How much energy will this system produce each day?
Production is site-specific. Array nameplate kW is not the same as daily kWh. Location, season, orientation, tilt, shading, weather, temperature, and system losses all affect production.
Will this eliminate my electric bill?
No specific bill reduction or zero-bill result is guaranteed. Utility rate structure, fixed charges, export compensation, energy use, and solar production all affect the final bill.
Do I need utility approval?
Grid-tied solar commonly requires utility interconnection approval and may require permits and inspections. Requirements vary by utility and jurisdiction.
Can this be installed DIY?
Installation requirements depend on the jurisdiction and utility. Electrical and interconnection work must follow manufacturer instructions, adopted code, permitting rules, and any licensing requirements that apply.
How do I know which Enphase kit size is right for me?
Size the array using your annual electricity usage, available roof or ground-mount area, local solar resource, utility rules, and your energy-offset goal rather than choosing by inverter size alone.
