15kw Off Grid Inverter with MPPT

15kW off-grid inverter with MPPT is a high-performance solution for medium-to-large off-grid setups—delivers stable AC power for commercial sites, large homes, and rural farms, maximizes solar harvest via multi-MPPT, integrates solar, batteries, and generators, and ensures uninterrupted energy in remote locations. Ideal for areas without grid access, it balances efficiency, reliability, and power to make off-grid operations feasible and cost-effective.

Products Description

1kw 3kw 5kw 10kw Off Grid Inverter

15kW Power Output: Delivers 15kW continuous AC power (surge capacity up to 45kW for 10 seconds) to handle heavy loads-industrial pumps, large HVAC systems, commercial refrigeration, and multiple household appliances. Optimized for single-phase (220V/240V) or three-phase (380V) systems (configurable), adapting to diverse off-grid wiring needs.

Multi-MPPT Technology: Equipped with 2-3 independent MPPT trackers (max DC input 800V each) with 99.3% efficiency, optimizing power extraction from 30-35 x 500W solar panels. Each tracker adapts to partial shading, mixed panel orientations (e.g., east-west arrays), or low light, boosting daily energy harvest by 30% compared to single-MPPT models-critical for off-grid energy security.

Off-Grid Exclusivity: Designed for complete grid independence-no grid-tie functionality, ensuring stable power in remote locations (e.g., rural plantations, island lodges, mining camps). Reliably converts solar DC to AC 24/7, even during extended cloudy periods or sudden load spikes.

Battery Compatibility & MPPT Charging: Works with 48V/192V lithium-ion (LiFePO4, NMC) and lead-acid batteries, supporting up to 150kWh storage via parallel/series connections. MPPT-based charging algorithms prevent overcharging, deep discharge, and cell imbalance, extending battery life by 35% in deep-cycle off-grid use.

Generator Integration with Automation: Built-in generator input (compatible with 20-25kW generators) and smart controls-auto-starts generators when battery SOC drops below 20% and stops at 80% charge to minimize fuel consumption. Configurable start/stop thresholds reduce manual intervention, ideal for unmanned remote sites.

Stable Output Under Fluctuating Loads: Advanced voltage regulation (±1%) maintains consistent AC output, even with sudden load changes (e.g., starting a compressor while running an AC unit). Prevents voltage dips or surges, protecting sensitive electronics (computers, control systems) and ensuring reliable performance for heavy machinery.
