Description
Productinformation in detail
Powerful Solar Technology for Maximum Energy Yield
The JA Solar 440W JAM54D41 LB All Black module, combined with a Deye hybrid inverter and the SE-G5.1 Pro-B battery storage, offers a modern solution for efficient solar energy utilization. The bifacial N-type high-performance module achieves a module efficiency of 22.53% and delivers good energy yield even in diffuse light. The dual-glass construction and a positive power tolerance of +5 W make it appealing for both residential and commercial installations. Its robust design is intended for long service life, backed by a 30-year linear performance warranty.
Intelligent Energy Distribution with Deye Hybrid Inverter
The Deye SUN-20K-SG05LP3-EU-SM2 is a three-phase hybrid inverter with a nominal power of 20 kW. It supplies consumers directly with solar power, stores excess energy in batteries, or feeds it into the grid. Two MPP trackers and the ability to handle 100% unbalanced loads allow flexible power distribution to each phase (up to 50% of nominal power per phase). The inverter operates with 48-V low-voltage batteries (LiFePO4 or lead-acid) and supports a wide battery voltage range of 40–60 V. This provides safe and stable integration into existing systems. The IP65 protection rating allows operation outdoors. Built-in protection features include DC polarity protection, overcurrent and overvoltage protection, short circuit protection, and thermal protection.
Expandable Storage for Full Energy Independence
The SE-G5.1 Pro-B is a 48-V LiFePO4 low-voltage battery storage with a capacity of 5.12 kWh (usable approx. 4.6 kWh). It is modularly expandable to up to 32 modules without additional hardware or 64 modules with external expansion, enabling a total capacity of up to 327 kWh. The storage operates in a temperature range of –20°C to +55°C. An integrated battery management system protects against overcharging, deep discharge, overcurrent, and temperature errors. The 19-inch standard housing allows space-saving rack, wall, or floor mounting. Features like WiFi/USB monitoring, automatic module networking, and remote maintenance are integrated. The lifespan is over 10 years (under normal operation), with a 10-year manufacturer's warranty.
