Ultra-Quiet Operation (<30 dB): Operates without cooling fans, making it quieter than a whisper and suitable for indoor living spaces.
High Efficiency: Delivers up to 97.6% maximum efficiency, 97.0% European efficiency, and 99.9% MPPT tracking efficiency.
Sub-20ms UPS Transfer: Automatically shifts to battery backup within 20 milliseconds during a power outage to prevent computers and sensitive appliances from restarting.
Wide 48V Battery Compatibility: Works with both Lead-acid and Lithium Iron Phosphate (LiFePO4) battery banks (40V–60V) at up to 100A charge/discharge current.
IP65 Weather Resistance: Fully protected against dust ingress and high-humidity monsoons, supporting outdoor or indoor wall mounting.
Integrated Wi-Fi Connectivity: Enables plant monitoring, yield reporting, and remote diagnostics through the SolisCloud mobile app and desktop portal.
Dual Independent MPPTs (12.5A per string): Allows flexible rooftop string design, ensuring system efficiency even if roof planes face different angles.
Natural Convection Cooling: By omitting mechanical fans, the unit eliminates a primary failure point in dusty environments while ensuring silent performance.
Zero Export & Grid Support: Includes integrated export power limiting, making it straightforward to match local net-metering rules or prevent reverse feeding.
Comprehensive Fault Protection: Integrated protections include DC reverse polarity, AC short circuit, over-current, over-voltage, anti-islanding, and thermal derating.
Residential duplexes and multi-story apartment loads
Small-to-medium offices, corporate workstations, and server racks
Retail storefronts, pharmacies, and clinics requiring continuous refrigeration or lighting
Agricultural farmhouses and rural properties operating on unstable or weak utility grids
Grid-tied rooftop solar installations requiring localized battery storage
Resilience Against Load Shedding: With <20ms automatic transfer, the inverter functions as an industrial-grade IPS/UPS without flicker or manual switching.
Engineered for Tropical Weather: The IP65 enclosure and -25°C to +60°C operating window handle high ambient summer heat and seasonal monsoon humidity.
Significant Cost Reduction: Self-consumption optimization and battery peak-shaving reduce dependence on higher-tier grid tariff rates.
Low Maintenance Requirements: A sealed fanless chassis eliminates internal dust clogging, lowering routine service requirements in urban and semi-urban environments.
