CORE FEATURE

🔋 SMART LOAD CALCULATOR
Add every appliance in your home or office with wattage, quantity, and daily usage hours. SolarGuard automatically calculates your total daily energy consumption (Wh) and peak load (W) using professional electrical engineering formulas.

⚡ INVERTER SIZING
Get the exact inverter capacity (kVA) you need based on your peak load. No more undersized inverters that trip or oversized ones that waste money.

🔋 BATTERY BANK DESIGN
Calculate required battery capacity accounting for:
• Night vs. daytime energy usage
• Battery chemistry (Lithium 90% DoD, Lead-Acid 50% DoD)
• Round-trip efficiency losses
• Real-world charge controller efficiency

☀️ SOLAR ARRAY SIZING
Determine exactly how many solar panels you need considering:
• Your location's peak sun hours (default: 4.5 for Nigeria)
• Day and night energy split
• Battery charging efficiency
• Safety factor for cloudy days

📐 STRING SIZING CALCULATOR
Calculate maximum series/parallel panel configurations based on your inverter's MPPT voltage and current limits. Prevents over-voltage damage.

🔌 CABLE & BREAKER SIZING
Get professional wiring recommendations:
• Cable size (mm²) with voltage drop calculations
• DC breaker ratings
• Battery cable specifications
• AC output wiring guide

📊 REAL-TIME SOLAR MONITOR
See live solar production data, battery levels, and energy flow using your phone's GPS location and real weather data. Track sun position, irradiance, and cloud cover.

🛒 PRODUCT RECOMMENDATIONS
Browse a database of real batteries and inverters available in the Nigerian market:
• Felicity, Luminous, Su-Kam, Genus, Mercury batteries
• itel, Felicity, Luminous, Su-Kam, Victron, Fronius inverters
Each with specifications, estimated prices (₦), and installer ratings.

📄 PROFESSIONAL REPORTS
Generate and share PDF or CSV reports with:
• Complete system specifications
• Appliance load breakdown
• Daily energy production logs
• Financial savings projections
• Bill of materials with estimated costs

🛡️ SYSTEM PROTECTION
Built-in safety checks warn you when:
• Required solar exceeds inverter PV input limit
• Peak load exceeds 80% of inverter rating
• Battery backup time is insufficient

📚 SOLAR ACADEMY
Learn solar fundamentals directly in the app:
• Peak Sun Hours explained for Nigerian latitudes
• Inverter architecture (Pure Sine Wave vs Modified)
• Depth of Discharge (Lithium vs Lead-Acid)
• String sizing formulas with examples
• Battery C-Rating and cycle life comparisons

🌍 LOCATION-AWARE
Automatically detects your GPS location to:
• Set local currency (₦ for Nigeria)
• Calculate accurate sun position and peak sun hours
• Provide location-specific solar tips

📱 WORKS OFFLINE
All calculations work without internet. Solar data updates when connected.

REAL FORMULAS, REAL RESULTS

SolarGuard uses professional electrical engineering standards:
• Daily Load = Σ (Watts × Quantity × Hours)
• Inverter Size = Peak Load × 1.25 ÷ 1000
• Battery Capacity = Night Load ÷ Depth of Discharge
• Solar Array = (Day Load + Battery Charging) × Safety Factor ÷ Peak Sun Hours
• Voltage Drop = 2 × Length × Current × Resistance ÷ 1000
