US-based DC power optimizer technology provider Tigo Energy has unveiled a new energy storage system for residential use.
“The Tigo GO Battery meets the demands of the European market with an optimized modular architecture built on 3.68 kWh battery units that installers can configure from 7.3 kWh for compact installations up to 47.9 kWh for larger households,” the company said in a statement. “Each battery module weighs 34 kg, allowing faster deployment while maintaining a compact footprint for installations with limited space.”
A system with two battery modules delivers 3.5 kW nominal power and 5.1 kW peak power. It operates at a nominal voltage of 102.4 V, with a voltage range of 90 V to 116 V, and measures 510 mm x 563 mm x 365 mm.
At the top end, a 12-module system delivers 23.3 kW nominal power and 33.2 kW peak power. It has a rated voltage of 665.6 V and an operating range of 585 V to 750 V. Its dimensions are 510 mm x 1,253 mm x 365 mm.
The IP65-rated system is based on lithium iron phosphate (LFP) chemistry and can operate over a wide temperature range. An integrated heating function allows charging at temperatures down to –30 C.
Cycle life is specified at more than 6,000 cycles at a depth of discharge of 90%.
The system is compatible with the Tigo EI inverter and integrates with the Tigo EI app for energy management and backup functionality. It supports both single-phase and three-phase configurations and allows a maximum charge and discharge current of 50 A.
“Developed in close collaboration with installers, the GO Battery features a modular architecture that simplifies system design and installation while providing flexibility and reliability for a wide range of residential applications,” the company said.
