Products Description
Off Grid Inverter
3kW Power Output Delivers 3kW continuous AC power (surge capacity up to 6kW for 5 seconds) with pure sine wave output, compatible with sensitive electronics (laptops, TVs) and everyday appliances (refrigerators, fans, small air conditioners). Optimized for 220V/240V single-phase systems (50/60Hz), matching standard wiring for small-scale off-grid applications.
High-Efficiency MPPT Tracker Equipped with 1 advanced MPPT channel (max DC input 500V) with 99.3% efficiency. The smart algorithm optimizes power extraction from 6-8 x 400W solar panels, adapting to partial shading (common in wooded areas), low light (dawn/dusk), or cloudy weather-boosting daily energy harvest by 28% compared to basic PWM chargers, critical for off-grid energy security.
Off-Grid Exclusivity Designed for complete grid independence, with no grid-tie functionality-ensuring stable power in remote locations (mountain cabins, rural homesteads, forest workshops). Reliably converts solar DC to AC 24/7, even during extended low-sunlight periods or sudden load spikes (e.g., starting a blender while running a microwave).
Battery Compatibility Works with 24V/48V lithium-ion (LiFePO4, NMC) and lead-acid batteries (deep-cycle), supporting up to 50kWh storage via parallel connections. MPPT-based 3-stage charging (bulk, absorption, float) prevents overcharging and deep discharge, extending battery life by 30% in off-grid deep-cycle use.
Generator Integration with Auto-Start Built-in input for 4-5kW single-phase generators-auto-starts when battery SOC drops below 20% (user-adjustable) and stops at 80% charge, minimizing fuel consumption. Manual override option allows flexible control during unexpected weather events.
Stable Single-Phase Output Advanced voltage regulation (±2%) maintains consistent 220V/240V output, even with fluctuating loads. Prevents voltage dips or surges, protecting sensitive devices (e.g., home electronics, power tools) and ensuring reliable performance for daily appliances.
