Products Description
3kw Off Grid Inverter
3kW Power Output: Delivers 3kW continuous AC power (surge capacity up to 6kW for 5 seconds) to handle essential loads-LED lighting, small refrigerators, TVs, fans, and power tools. Optimized for 220V/240V single-phase systems (50/60Hz), matching standard off-grid wiring for small-scale applications.
High-Efficiency MPPT: Single MPPT tracker (max DC input voltage 500V) with 99.0% efficiency, optimizing power from 6-8 x 400W solar panels. Performs well in low light (dawn/dusk) or partial shading (common in wooded areas), boosting daily energy harvest by 28% vs. basic PWM chargers.
Off-Grid Exclusivity: Designed for complete grid independence-no grid-tie functionality, ensuring stable power in remote locations (e.g., mountain cabins, desert camps, off-grid tiny homes). Reliably converts solar DC to AC for 24/7 operation, even in variable weather.
Battery Compatibility: Works with 12V/24V/48V lithium-ion (LiFePO4) and lead-acid batteries (deep-cycle), supporting up to 50kWh storage via parallel connections. Intelligent charging (3-stage: bulk, absorption, float) prevents overcharging and deep discharge, extending battery life by 25% in off-grid cycles.
Generator Backup Integration: Built-in generator input (compatible with 3-5kW portable generators) for cloudy periods. Auto-starts generators when battery SOC drops below 20% and shuts off at 80% charge, saving fuel. Manual override option for user-controlled charging.
