EI Residential Solution Overview
The Tigo Energy Intelligence (EI) Battery provides energy resilience in the event of a grid
outage and optimizes energy consumption based on rate plans for
today’s home energy needs.
The Tigo EI Battery is the energy st
orage component of Tigo’s Energy Intelligence Solution.
Each enclosure contains three battery modules for a total capacity of 9.9kWh.
The Energy Intelligence Residential Solution
The EI Residential Solution includes the following components:
1.
EI Inverter
–
The TSI-7.6K-US and TSI-11.4K-US inverters may be installed as grid-
tied only or as an energy storage system when paired with the EI Battery. The inverter
converts the PV array’s DC energy to AC for
use in the building and when paired with an
EI Battery, acts as the battery management unit.
2.
TS4
–
Tigo’s
MLPE, the TS4-A-F provides module-level rapid shutdown. The TS4-A-O
provides module-level monitoring, rapid shutdown, and best-in-class module-level
optimization with Tigo’s patented
Predictive IV.
3.
EI Battery
(optional)
–
The LFP battery is designed for use specifically with the EI
Inverter. Up to four battery enclosures may be installed with the EI Inverters.
4.
EI ATS
(required when batteries are used)
–
The EI ATS is an automatic transfer switch
that switches the home loads from grid + Solar/battery usage to solar/battery usage
only when the grid goes down. This is a required component of any energy storage
system when connected to the utility grid as it prevents the potential for dangerous
backfeed on the utility
’s
conductors.
5.
Energy Meter
–
(optional / required when batteries are used)
–
The energy meter
monitors the import and export of energy into the
home’s
electrical system. This allows
the inverter to determine when and how much energy is required from the battery to
serve connected loads.
6.
Energy Intelligence
–
Accessible through the web or mobile app, the EI Platform
provides visibility into system and module performance. The EI mobile app is also used
for commissioning the EI Residential Solution.
