 MEGAPACK 2 SPECIFICATION

1 System Description
Tesla Megapack 2 (“Megapack”) is an all-in-one utility-scale energy storage system optimized for cost
and performance. It scales to the space, power, and energy requirements of any site from 1 MWh to 1
GWh+. The product is a complete energy storage solution including batteries, bi-directional inverter,
thermal system, and a Tesla Site Controller with intelligent software.

This turnkey system is designed to maximize savings and prolong battery life. Megapacks have the most
advanced battery technology and dispatch optimization software to quickly learn and predict a facility’s
energy patterns. Tesla’s proprietary storage dispatch software can charge and discharge autonomously
to maximize customer value.

Megapack’s architecture consists of battery cells aggregated into modules, and power electronics
modules. Both are thermally managed by an integrated liquid cooling and heating system for thermal
safety, enhanced performance, and reliability. The architecture also includes sensors supporting
embedded monitoring and controls as well as electrical interface equipment including an industry
standard breaker for AC protection.

1.1 Application
Megapack is capable of various on-grid applications such as tariff optimization, peak load shaving,
energy shifting, and demand response. In addition, the system can operate as a microgrid to support
backup and islanded systems.

1.2 Capacity Maintenance

Megapack can be provided with a Capacity Maintenance Agreement (CMA), which guarantees power
and energy capacity over the life of the product. A capacity-maintained system requires the addition of
battery modules over time to maintain power and energy. The product is designed to accommodate
these additions over time without impact to site design. This specification describes up to a 10-year
capacity-maintained system operated up to one full cycle per day. Upon request, Tesla can also provide
specifications for CMA lengths of 15 or 20 years. Technical details and characteristics differ between a
product with Capacity Maintenance Agreement and a product without. These differences are highlighted
in the relevant sections within this specification. Capacity maintenance is offered for projects with a
minimum size of 10 MWh.

1.3 Constituent Parts

Each Megapack enclosure includes the following components provided by Tesla:
 Smart inverter
 AC main breaker
 Battery modules
 Thermal system
 Tesla Site Controller
 Low voltage interface panel

 MEGAPACK 2 SPECIFICATION

2 Technical Specifications
Megapack is rated in terms of net-delivered power and minimum energy at its AC output terminals. Loads
and losses, including power conversion, thermal system losses, auxiliary loads, and chemical/ionic losses
are considered internal to the system and ratings are net of these loads. Losses between the AC output
terminals and the point of interconnection with the customer/utility are site-dependent and excluded from
the rated power and energy.

2.1 Power and Energy

System ratings are defined in kWp and kWh as measured at the AC terminals of the Megapack. The
given energy ratings (kWh) in this document are minimum initial energy ratings.

Megapack is capable of providing nameplate kWh energy at nameplate kW when discharged from
100% SOE at STC. Megapack is capable of charging or discharging at the rated power for the life of the
system. The maximum duration of charge/discharge will decrease over the life of the system. The kW is
net of thermal loads and can be achieved throughout life.

A fully populated Megapack has the following nominal ratings at 480 V AC:

Table 1: Nominal Energy Ratings

AC Minimum Initial
System Duration AC Power (kVA) AC Power (kWp)
Energy (kWh)

2-hour 1,680 1,280 2,560

2-hour, CMA only 1,890 1,440 2,880

4-hour 997.5 761.9 3,047.6

2.1.1 Scaling Power and Energy

Megapack can be requested with lower factory-configured inverter ratings. See Section 2.4.1.6
Inverter Configurations for more details.

Megapack can be requested with fewer battery modules. See section 2.4.1.7 for more details.

2.2 Roundtrip Efficiency and Energy Consumption

Roundtrip efficiency (RTE) is defined as the relative difference in energy charged to the system from 0%
SOE to 100% SOE at kWp immediately followed by energy discharged the system from 100% SOE to
0% SOE at kWp. The quotient of energy discharged over energy charged is the RTE. This RTE includes
all thermal system energy consumption and all internal Megapack control power consumption during the
cycle.

CONFIDENTIAL– SHARED UNDER NDA ONLY | PRE-PRODUCTION/SUBJECT TO CHANGE Page 8 of 19

The roundtrip efficiency and auxiliary energy consumption is specified in the table below:

TAMBCOLD: 87.5% TAMBCOLD: 90.5%
** Indicative figures. Exact value will depend on battery utilization and climate over the 15 years.

2.3 Charge and Discharge Limitations

Megapack’s thermal management system is used to maintain the battery’s charge and discharge
capabilities across the system’s rated temperature range. In cold ambient conditions, operating in this
state results in lower overall efficiency due to increased parasitic loads.

By activating heat mode, the 2-hour or 4-hour Megapack can be preconditioned to allow rated
charge/discharge power. Heating will be required if Megapack battery temperature drops below 20C.

Table 12 lists standard inverter configurations of the Megapack. Additionally, Megapack can be
requested to be factory-configured with any particular current limit lower than the maximum below to

3 Communication and Control

The Tesla Site Controller is the main data concentrator for a Megapack site and is the single node
through which the system can communicate with Tesla servers and other third-party interfaces. When
connected to an external network (either over GSM or Internet), the Tesla Site Controller can be used for
monitoring and controlling the system.

The Tesla Site Controller is capable of collecting data from all equipment installed onsite, including the
AC meters. The Tesla Site Controller communicates to external interfaces via Modbus TCP, DNP3, or
REST API.

The Tesla Site Controller has the following interfaces:

 (1) 10/100/1000 Ethernet port for third-party interface connection
 (4) 10/100/1000 Ethernet ports for meters

Refer to the Tesla Energy Controls and Communications Manual for details.
