Overview
The Tigo EI Residential Solar Solution optimizes home energy consumption based on rate plans
and today’s energy needs. It’s built with the following components:
1. EI Inverter – A 7.6kW or 11.4kW hybrid inverter may be installed grid-tied only or as
part of an energy storage system (ESS) when paired with up to four Tigo EI batteries.
2. TS4 MLPE – Tigo’s PV module-level power electronic (MLPE) components optimize solar
module performance and provide module-level monitoring and rapid shutdown. A Tigo
Access Point (TAP) with a wired connection to the inverter communicates with TS4
components wirelessly.
3. EI Battery – Up to four lithium-iron-phosphate (LFP) EI batteries are designed for use
specifically with the EI solution.
4. EI Automatic Transfer Switch (ATS) – The ATS senses grid loss and safely switches
from grid + solar/battery power to solar/battery power only. It also supports adding a
generator to the solution.
5. The Tigo Energy Intelligence platform and mobile app enables easy system
commissioning and provides comprehensive ongoing visibility into system and module
performance.
