Solar-powered Single Phase Inverter Off Grid 15kw

15kW single-phase off-grid solar inverter is a high-capacity, purpose-built solution for large-scale grid-free setups—ideal for spacious rural estates, commercial farms, remote industrial workshops, and small off-grid communities. It delivers robust single-phase AC power, maximizes solar harvest via advanced MPPT, integrates seamlessly with batteries and generators, and ensures reliable energy in locations without utility access. Perfect for users needing consistent 220V/240V power for heavy loads, it balances performance, durability, and scalability for demanding off-grid applications.

Products Description

15kw Off Grid Inverter

15kW Single-Phase Power Output Delivers 15kW continuous AC power (surge capacity up to 45kW 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.

Dual MPPT Trackers Equipped with 2 independent MPPT channels (max DC input 600V each) with 99.5% efficiency. The advanced algorithm optimizes power extraction from 30-35 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 maximizing energy in large off-grid setups.

Off-Grid Exclusivity Designed for complete grid independence, with no grid-tie functionality-ensuring stable power in remote locations (mountain resorts, rural plantations, island facilities). 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 225kWh storage via parallel/series connections. MPPT-based 3-stage charging (bulk, absorption, float) 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 18-20kW 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 single-phase loads, critical for maintaining operations in remote sites.
