UTL 1.5kW Off Grid Solar System | 510W TOPCon | Gamma+ 1650 | 12.8V (100AH) Li-ion Battery

The UTL 1.5kW Off-Grid Solar System is designed to deliver consistent and dependable electricity for homes facing frequent power cuts. Built with high-efficiency 510W TOPCon bifacial solar panels, a Gamma+ rMPPT solar inverter, and a durable 12.8V (100Ah) lithium-ion battery, this complete Solar Inverter with Battery SPGS delivers reliable and uninterrupted power for your essential appliances.
The system comes with 3 × 510W TOPCon bifacial solar panels designed with advanced 144 half-cut cell technology. This smart cell configuration increases power output while minimizing internal energy loss, ensuring better performance throughout the day. This means it performs better even when part of the panel is shaded or when temperatures are high. TOPCon (Tunnel Oxide Passivated Contact) technology enhances cell efficiency by reducing recombination losses which allows higher energy generation compared to conventional panels. Being bifacial, these panels generate electricity from both the front and rear sides. Reflected sunlight from rooftops or surrounding surfaces contributes additional power. With a 27-year performance warranty, the panels are built for long-term reliability and consistent generation.

The system is powered by the Gamma+ single-phase off-grid inverter, equipped with advanced rMPPT (Rapid Maximum Power Point Tracking) technology. This ensures the panels operate at their optimal power point throughout the day, maximizing solar energy harvest. The integrated 12.8V lithium-ion battery offers faster charging, deeper discharge capability, and longer life compared to traditional batteries. With an expected 10-year battery life, it ensures reliable backup during the evening and extended outages.
