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 off-grid wiring for small-scale applications.
Single MPPT Tracker (Growatt Efficiency): 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. Adapts 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.
Off-Grid Exclusivity: Designed for complete grid independence, with no grid-tie functionality-ensuring stable power in remote locations (e.g., mountain cabins, desert camps, off-grid tiny homes). Growatt's robust inversion technology converts solar DC to AC 24/7, even during extended cloudy periods.
Battery Compatibility & BMS Integration: Works with 24V/48V lithium-ion (LiFePO4) and lead-acid batteries (deep-cycle), supporting up to 60kWh storage via parallel connections. Integrated with Growatt's smart charging logic to prevent overcharging and deep discharge, extending battery life by 30% in off-grid deep-cycle use.
Generator Integration with Auto-Start: 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. Manual override option allows flexible control for DIY off-grid setups.
