Your solar panels generate DC power, but your home and appliances run on AC power. The inverter is the device that makes the conversion — and it's the brain of your entire solar system.

Choose wrong, and you'll face compatibility issues, lower efficiency, or expensive upgrades later. This guide breaks down everything you need to know.

## 1. The Three Main Types of Solar Inverters

### 🔄 Hybrid Inverter (Most Popular)

**Best for**: New installations, battery-ready systems, grid-tied with backup

A hybrid inverter manages both solar panels and battery storage in one unit. It can:

- Convert solar DC to home AC

- Charge batteries from solar or grid

- Provide backup power during outages

- Sell excess power back to the grid

**Pros**: All-in-one solution, simpler installation, future battery-ready  

**Cons**: Higher upfront cost than string inverters  

**Best for**: 90% of residential and small commercial installations

### 🔗 String Inverter (Traditional)

**Best for**: Large roof arrays, budget-conscious installations

All panels connect in a "string" to one central inverter.

**Pros**: Lower cost, simple maintenance, proven technology  

**Cons**: Entire string affected if one panel is shaded, no battery integration, no backup power  

**Best for**: Large commercial rooftops with no shading

### ⚡ Microinverter (Per-Panel)

**Best for**: Complex roofs with shading, panel-level monitoring

Each panel has its own small inverter.

**Pros**: Each panel works independently, best for shaded roofs, detailed monitoring  

**Cons**: Highest cost, more points of failure, harder to service  

**Best for**: Complex roof layouts with partial shading

## 2. Key Specifications to Compare

| Spec | What It Means | What to Look For |

|------|--------------|------------------|

| **Power rating** | Maximum output (kW) | Match your solar array size |

| **MPPT input** | Number of solar inputs | 2-3 MPPT for flexibility |

| **Efficiency** | Conversion efficiency | >97% (most good inverters) |

| **Surge rating** | Peak power for motor starts | 1.5x continuous rating |

| **IP rating** | Weather/dust protection | IP65+ for outdoor mounting |

| **Warranty** | Coverage period | 5-10 years (extendable) |

---

## 3. Sizing Your Inverter

Simple rule: **Inverter size should match your solar array size.**

| Solar Array Size | Recommended Inverter | Daily Output (est.) |

|-----------------|---------------------|---------------------|

| 3kW | 3kW-3.6kW hybrid | 12-15 kWh |

| 5kW | 5kW-6kW hybrid | 20-25 kWh |

| 8kW | 8kW-10kW hybrid | 32-40 kWh |

| 10kW | 10kW-12kW hybrid | 40-50 kWh |

| 15kW+ | 15kW-20kW hybrid or 3-phase | 60-80+ kWh |

**Oversizing tip**: If you plan to add more panels later, choose an inverter with 20-30% higher capacity than your current array.

## 4. Battery Compatibility

Not all inverters work with all batteries. Check these before buying:

| Factor | What to Check |

|--------|--------------|

| **Voltage** | Compatible battery voltage (48V most common) |

| **Communication** | CAN bus / RS485 protocols |

| **Brand compatibility** | Some inverters only work with specific battery brands |

| **Charge profile** | LiFePO4 (14.4-14.6V per module) |

**Fowojet inverters are tested and compatible with major LiFePO4 battery brands**, including our own Fowojet battery series.

## 5. Grid-Tie vs Off-Grid vs Hybrid

| Type | Grid Connection | Battery | Backup Power | Best For |

|------|----------------|---------|-------------|----------|

| **Grid-tie** | Required | No | No | Net metering, low cost |

| **Off-grid** | No | Required | Yes | Remote areas, no grid access |

| **Hybrid** | Optional | Optional | Yes | Most installations |

---

## 6. Single-Phase vs Three-Phase

| | Single-Phase | Three-Phase |

|--|-------------|-------------|

| Max power | Up to 12kW | 15kW+ |

| Typical use | Homes, small shops | Large homes, businesses, farms |

| Voltage | 220-240V | 380-415V (3-phase) |

| Common in | Africa, Asia, Europe homes | Europe, large properties |
