# Inverters Manage your inverter inventory with specifications, documentation, and media. Configure microinverters and string inverters for accurate quote generation. ## Adding Inverters ### From Powerlily Database 1. **Equipment** → **Inverters** → **"Add from Powerlily List"** 2. Browse and select inverters 3. Customize as needed ### Creating Custom Inverters 1. **Equipment** → **Inverters** → **"New Inverter"** 2. Fill in specifications 3. Configure type (micro vs string) 4. Upload documentation 5. Save ## Basic Specifications **Brand:** Select from brand list or enter custom - Common: Enphase, SolarEdge, SMA, Fronius, Generac, APSystems **Name:** Display name for quotes and catalog - Example: "Enphase IQ8+ Microinverter" **Model:** Manufacturer model number - Example: "IQ8PLUS-72-2-US" **Rated AC Power Output:** Continuous AC power in watts - Microinverters: 250W-380W+ - String inverters residential: 3kW-11.4kW - String inverters commercial: 20kW-100kW+ **Efficiency:** Peak efficiency percentage - Typical: 96-98% **Warranty:** Coverage length in years - Standard: 10-25 years **Value:** Your wholesale cost per inverter - Microinverters: $100-$300 - String inverters: $800-$4,000+ **Video:** YouTube video ID or URL **Description:** Rich text product information, key features, monitoring capabilities ## Inverter Type Configuration ### String Inverters **Configuration:** - Leave "Micro" toggle OFF - One inverter per array (or multiple for large systems) - Quantity adjustable in quotes **Best for:** Unshaded roofs, simple layouts, cost-sensitive projects, commercial ### Microinverters **Configuration:** - Toggle "Micro" ON - Set "Panels Serviced" (1-4) - **1:1** - One micro per panel (maximum optimization, highest cost) - **2:1** - Most common (Enphase IQ8+, IQ8M) - **3:1** - Some commercial applications - **4:1** - Largest ratios (some APSystems) - Inverter quantity auto-calculated from panel count **Example:** 24 panels with 2:1 micro = 12 microinverters **Best for:** Shaded roofs, complex layouts, multiple orientations, premium systems ## String Inverter Electrical Specifications *Only for string inverters - hidden for microinverters* **Number of MPPTs:** Maximum Power Point Trackers (1-6) - Each MPPT independently optimizes a string or group of strings **Strings per MPPT:** String inputs per MPPT channel (1-4) **Max DC Power:** Maximum total DC input power (W) - Example: 11400W **Max DC Power per MPPT:** Maximum DC power per MPPT channel (W) - Example: 5700W **Max Voc Input:** Maximum open-circuit voltage from DC input (V) - Example: 480V **Min Input Voltage:** Minimum DC voltage required to operate (V) - Example: 380V **Max MPPT Voltage:** Maximum voltage for MPPT operation (V) **Min MPPT Voltage:** Minimum voltage for MPPT operation (V) **Max Input Current:** Maximum DC input current per string (A) **Max Short Circuit Current:** Maximum allowable short-circuit current (A) *These specs are critical for proper string design and code compliance* ## Visibility & Media **Visible:** Toggle to show/hide from new quotes - Disable for discontinued models or out of stock - Existing quotes unaffected **Draw Ready:** Automatic validation - Requires: valid watts **Images:** Upload multiple product photos (JPG, PNG, HEIC) **Spec Sheet:** PDF datasheet for customers **Additional Documents:** Installation manuals, warranties, certifications **Video:** YouTube video ID or URL ## QR Codes Auto-generated QR code for each inverter linking to its public equipment page - Available as SVG or PNG - Use on brochures, boxes, materials ## Management **Editing:** Changes affect new quotes only; existing quotes unchanged **Deleting:** - Can delete: Unused inverters - Cannot delete: Used in any quote - Alternative: Set Visible = False **Cloning:** Duplicate to create variants with different pricing or specs ## Best Practices - Verify specifications from manufacturer datasheets - For microinverters: toggle "Micro" ON and set correct "Panels Serviced" - For string inverters: fill in electrical specs for proper string design - Include spec sheets and product images - Update pricing regularly ## Common Configurations **Residential String System (6-8kW):** - Single string inverter: 6000W-8000W - 20-25 panels × 400W - Example: SolarEdge SE7600H, 7600W, 20 panels = 8000W DC (1.05 DC/AC ratio) **Residential Microinverter System:** - Toggle Micro ON, 2 panels serviced - 24 panels = 12 inverters - Example: Enphase IQ8+, 300W AC, with 400W panels × 2 **Commercial String System:** - Multiple large string inverters: 20kW-50kW each - Example: SMA Sunny Tripower 50kW, 200× 400W panels = 80kW DC, 2 inverters --- **Related:** [[Panels|Solar Panels]] | [[Equipment|Equipment Overview]] | [[Equipment Catalogue|Equipment Catalogue]]
