Growatt Solar Inverter 3.5kw

3.5kW Power Output Delivers 3.5kW continuous AC power (surge capacity up to 7kW for 5 seconds) with pure sine wave output, compatible with sensitive electronics (laptops, TVs) and small appliances (refrigerators, fans, power tools). Optimized for 220V/240V single-phase systems (50/60Hz), matching standard wiring for small-scale setups.

High-Efficiency MPPT Tracker Equipped with 1 high-performance MPPT channel (max DC input 500V) with 99.3% efficiency. Growatt's proprietary algorithm optimizes power from 7-9 x 400W solar panels, adapting to low light (dawn/dusk), partial shading (common in wooded areas), or cloudy weather-boosting daily energy harvest by 28% compared to basic PWM chargers, critical for off-grid reliability.

Dual Modes (Grid-Tied/Off-Grid) Available in grid-tied or off-grid configurations. Grid-tied models feed excess solar power to the utility grid (where allowed) with 98.2% inversion efficiency, maximizing self-consumption and feed-in tariffs. Off-grid models operate independently, ensuring power in remote locations (mountain cabins, desert camps) without grid access.

Battery Compatibility (Off-Grid Models) Off-grid variants work with 24V/48V lithium-ion (LiFePO4) and lead-acid batteries (deep-cycle), supporting up to 60kWh storage via parallel connections. Integrated charging logic prevents overcharging and deep discharge, extending battery life by 30% in off-grid deep-cycle use.

Generator Integration (Off-Grid) Off-grid models include a built-in input for 4-6kW portable generators. Auto-starts when battery SOC drops below 20% (user-adjustable) and stops at 80% charge, minimizing fuel use-ideal for extended cloudy periods.

Growatt ShineMonitoring System Connects to Growatt's ShinePhone app via Bluetooth/WiFi, displaying real-time metrics: solar input (kWh), battery SOC (off-grid), load consumption, and MPPT performance. Users can check system status remotely, receive alerts for faults, and adjust settings (e.g., generator thresholds) via the app.
