Overview

EI Residential Solar Solution Installation Manual | www.tigoenergy.com | [email protected] 1

Overview

The Tigo EI Residential Solar Solution optimizes energy consumption based on rate plans and

today’s home energy needs. It uses the following hardware components:

•EI Inverter – A single- or three-phase Tigo EI Inverter may be installed as grid tied

only or as part of an energy storage system when paired with a Tigo EI Battery.

•EI Link – The inverter’s link component provides a single connection location for

communications and AC/DC wiring.

•TS4 MLPE – Tigo’s module-level power electronic (MLPE) components optimize solar

module performance and provide module-level monitoring and rapid safety shutdown. A

Tigo Access Point (TAP) enables wireless communication with TS4 components with a wired

connection to the inverter.

•Battery management system (BMS) – The BMS component provides protection,

internal monitoring, and management electronics.

•EI Battery – Up to four lithium-iron-phosphate (LFP) EI batteries are designed for use

specifically with the EI Inverter.

The Tigo Energy Intelligence Android/iOS mobile app enables easy system commissioning

and provides comprehensive ongoing visibility into system and module performance.

Overview – Safety

Safety

The EI system must be installed and maintained by qualified personnel in accordance with local

electrical codes. In addition:

•Components must operate within the technical specifications listed in their datasheets.

•Failure to follow instructions herein may cause equipment damage not covered by the

warranty.

•Use only copper conductors rated 75°C or higher. Do not use fine-stranded conductors.

•Unused conduit openings must be properly sealed. Connected conduit must use

appropriate fittings. Tigo EI product enclosures are rated IP65.

•Always wear appropriate PPE and use insulated tools.

These safety symbols appear in the manual:

hazardous situation which could result in serious injury or loss of life.

hazardous situation which could result in minor or moderate injury and

damage to the product.

An important operational note.

These symbols appear on Tigo enclosures:

Risk

of electrical shock.

Risk

of burns.

Check

the operating instructions.

Caution,

disconnection.

Avoid tampering.

Observe c

aution.

Pre-Installation – Location

EI Residential Solar Solution Installation Manual | www.tigoenergy.com | [email protected] 3

Pre-Installation

Location

The default enclosure layout for an EI system is, from the top down:

•Inverter

•Link

•Battery management system (BMS)

•Battery (one or two). Additional batteries may be placed to the right of the main

cabinet.

Locate EI components:

•In a well-ventilated, easily accessible location.

•On a flat surface against a solid wall without tilt.

•Sheltered from direct sunlight and precipitation. The ambient temperature should be

below 50°C.

•Away from antennas or other sources of strong electromechanical interference.

•Above potential flooding.

•With a minimum 300mm clearance around the top and sides.

When installing multiple batteries, consider that expansion connections are on

the right side of the main cabinet.
