| 1. Small off-grid inverter | Approximately 300 W–1.5 kW; commonly available with 12 V or 24 V DC input | 12 V or 24 V lead-acid or lithium battery, subject to model compatibility | Lighting, routers, televisions, and other low-power appliances in cabins or small homes | Check continuous output, surge capacity, DC cable requirements, and whether the unit provides a pure sine-wave output. |
| 2. Mid-range off-grid inverter | Approximately 1–5 kW; 24 V and 48 V models are common | Typically 24 V or 48 V battery systems | Basic household loads, small solar installations, and homes without a reliable grid connection | Compare surge rating, solar-charging capability, AC charging options, and supported battery chemistry. |
| 3. High-capacity off-grid inverter | Approximately 5–12 kW; often designed for 48 V battery systems | Usually a 48 V battery bank; some systems allow parallel battery or inverter expansion | Whole-home backup or off-grid systems serving several household circuits | Confirm that battery current, inverter surge output, wiring, and protective devices are sized for the intended loads. |
| 4. Grid-tied solar inverter | Single-phase residential models commonly range from about 1–10 kW | No battery required for standard grid-tied operation | Homes using rooftop solar to supply household loads and export eligible surplus electricity | Check local grid-code approval, phase compatibility, MPPT inputs, and whether export control is supported. |
| 5. Single-phase hybrid inverter | Common residential ratings are approximately 3–10 kW | Often compatible with 48 V low-voltage batteries or model-specific high-voltage batteries | Homes combining rooftop solar, battery storage, grid supply, and backup power | Verify battery compatibility, backup output rating, transfer behavior, and whether backup operation requires a separate circuit. |
| 6. Three-phase hybrid inverter | Residential and small-property models commonly span roughly 5–20 kW | Battery voltage and supported capacity depend on the model | Three-phase homes, larger residences, and properties with balanced three-phase loads | Check phase-balancing limits, per-phase output, grid requirements, and support for the selected battery system. |
| 7. Solar inverter with integrated MPPT charger | Commonly offered from about 1–6 kW, with solar-input limits varying by model | Usually 12 V, 24 V, or 48 V battery systems, depending on inverter rating | Compact off-grid or backup installations where solar charging and inverter functions are combined | Compare the MPPT voltage window, maximum PV input current, permitted PV array power, and battery charging current. |
| 8. Inverter-charger for backup power | Typically around 1–10 kW, with AC charging and transfer functions on supported models | Battery voltage and chemistry are model-specific | Homes needing battery backup with grid or generator charging during outages or low-solar periods | Check AC input limits, charging settings, transfer time, neutral-earth arrangements, and generator compatibility. |
| 9. Modular or parallel-capable inverter | Individual units are commonly in the 3–10 kW range; total capacity depends on approved parallel configurations | Designed for compatible battery banks; parallel battery arrangements require manufacturer guidance | Homes that may expand solar, storage, or backup capacity over time | Confirm the maximum supported number of units, synchronization requirements, firmware compatibility, and shared-battery limits. |
| 10. Compact inverter for essential-load backup | Approximately 500 W–3 kW, depending on whether the design is off-grid or hybrid | Commonly paired with a small 12 V, 24 V, or 48 V battery system | Dedicated backup for lighting, communications, refrigeration, or selected household circuits | Size the inverter for both running and starting loads; confirm which circuits can be backed up and for how long. |
