Products Description
20kw Off Grid Inverter
20kW Single-Phase Power Output Delivers 20kW continuous AC power (surge capacity up to 60kW for 10 seconds) with pure sine wave output, compatible with sensitive electronics (servers, medical equipment) and heavy single-phase loads (large HVAC systems, commercial refrigeration, industrial pumps). Optimized for 220V/240V single-phase systems (50/60Hz), matching standard wiring for large residential and small commercial off-grid setups.
Multi-MPPT Trackers Equipped with 2-3 independent MPPT channels (max DC input 800V each) with 99.5% efficiency. Advanced MPPT algorithms optimize power extraction from 40-50 x 500W solar panels, adapting to partial shading, mixed orientations (e.g., east-west arrays), or low light-boosting daily energy harvest by 30% compared to single-MPPT models, critical for large off-grid energy security.
Off-Grid Exclusivity Designed for complete grid independence, with no grid-tie functionality-ensuring stable single-phase power in remote locations (rural plantations, island resorts, mining camps). Reliably converts solar DC to AC 24/7, even during extended cloudy periods or sudden load spikes (e.g., starting multiple industrial tools simultaneously).
Battery Compatibility Works with 48V/96V lithium-ion (LiFePO4, NMC) and lead-acid batteries (deep-cycle), supporting up to 300kWh storage via parallel/series connections. MPPT-based charging prevents overcharging, deep discharge, and cell imbalance, extending battery life by 35% in deep-cycle off-grid use.
Generator Integration with Auto-Start Built-in input for 25-30kW single-phase generators-auto-starts when battery SOC drops below 20% (user-adjustable) and stops at 80% charge, minimizing fuel consumption. Seamless transition between solar/battery/generator (≤5ms) ensures no disruption to connected loads.
