Sigenergy Sigen PV 50M1

• Manufacturer Sigenergy
• IP Rating IP66

The Sigenergy Sigen PV 50M1 is a robust and intelligent 50kW three-phase inverter engineered for commercial and industrial solar projects requiring high-efficiency energy conversion and scalable system design. With cutting-edge safety features, flexible PV input architecture, and outdoor-ready construction, this inverter is ideal for installers delivering large-scale, grid-tied solar systems with long-term reliability.

Designed to handle up to 100,000Wp of PV input power and equipped with four independent MPPTs, the Sigenergy Sigen PV 50M1 supports up to 8 PV strings for optimal energy harvesting, even under varying irradiance conditions. Its smart air cooling system and compact, lightweight housing (75kg) simplify installation and reduce on-site labour costs.

Key Features of the Sigenergy Sigen PV 50M1:

High Power Performance
Supports 50kW nominal output with up to 55kW peak power, ideal for mid-size commercial PV arrays.

Flexible PV Input Configuration
Four MPPTs with wide voltage range (160V–1000V) and 32A per MPPT allow for efficient system layout and maximised energy yield.

Maximum Efficiency of 98.6%
Delivers outstanding energy conversion with minimal loss, supported by a European weighted efficiency of 98.3%.

Advanced Safety Protections
Features DC reverse polarity protection, AFCI (Arc Fault Circuit Interrupter), insulation and residual current monitoring, AC surge protection, and anti-islanding compliance for safe operation.

Scalable System Design
Enables parallel inverter operation without a data logger, allowing flexibility in larger installations.

Outdoor-Ready Durability
IP66-rated enclosure, smart air cooling, and operation in temperatures from -30°C to +60°C ensure performance in harsh conditions.

Communication & Monitoring
Offers multiple options including WLAN, Fast Ethernet, RS485, and Sigen CommMod (4G/3G/2G) for seamless integration into monitoring platforms.

Smart Installer Convenience
Quick PV and AC connection types (MC4 / OT or DT terminals), low night power draw (<3.5W), and support for up to 5,000m installation altitude (derating above 4,000m).

The Sigenergy Sigen PV 50M1 offers exceptional value for commercial solar installers looking for power, protection, and intelligent design—making it an ideal choice for distributed PV systems, business rooftops, and multi-inverter arrays.
