MPPT 5.5kw Off Grid Inverter

5.5kW off-grid inverter with MPPT is a versatile, mid-sized solution for small to medium off-grid setups—ideal for rural homes, remote workshops, small farms, and cabin communities. It delivers stable AC power, maximizes solar harvest via high-efficiency MPPT, integrates seamlessly with batteries and generators, and ensures reliable energy in grid-free locations. Perfect for users balancing power needs with efficiency and simplicity, it makes off-grid living and operations feasible and cost-effective.

Products Description

1kw 3kw 5kw 10kw Off Grid Inverter

5.5kW Power Output Delivers 5.5kW continuous AC power (surge capacity up to 11kW for 5 seconds) with pure sine wave output, compatible with sensitive electronics (computers, TVs) and medium loads (refrigerators, small HVAC systems, power tools). Optimized for 220V/240V single-phase systems (50/60Hz), adapting to standard off-grid wiring for mid-sized applications.

High-Efficiency MPPT Tracker Equipped with 1 advanced MPPT channel (max DC input 500V) with 99.3% efficiency. The smart MPPT algorithm optimizes power extraction from 11-14 x 400W solar panels, adapting to partial shading, 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.

Battery Compatibility Works with 48V lithium-ion (LiFePO4, NMC) and lead-acid batteries (deep-cycle), supporting up to 70kWh storage via parallel connections. MPPT-based charging 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 6-8kW 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.
