1.5 Functional Overview

The Evolve Hub is equipped to support an AC coupled solar plus storage installation with backup power to a dedicated

backup electrical panel. The Evolve Hub is a power distribution center for the Evolve ESS, routing all AC power between

the main and backup electrical panels. In the event of a grid outage, the Evolve Hub will be energized by the ESS, which

will island off the main electrical panel. As shown below, the V inverter’s AC output is connected to the backup panel to

support solar charging of the battery during a grid outage.

igure 2: Evolve Hub and Evolve ESS solar plus storage.

1.5.1 Grid Connected Solar plus Storage

The Evolve Hub routes power from the main electrical

panel to the backup panel through the Evolve ESS

Grid/Load transfer circuit when the grid is live and the

battery system is in service (normal operation). The

EMC commands the battery system to charge or

discharge the battery as demanded by the energy

management algorithm. In a self-consumption

algorithm, for example, the EMC calculates the

difference in total load vs. solar V, and routes the

balance of power to/from the battery as needed.

When the battery is full, V power bypasses the

battery to grid/loads. When the battery is at

minimum reserve, all home loads are supplied entirely

by the grid. The following diagram outlines the power

flow possibilities while grid connected.

Note: The Evolve Hub is equipped with an internal automatic bypass switch which provides uninterrupted service to the

backup electrical panel when the Evolve ESS is either not powered (installed but pending permission to operate) or out of

service.

1.5.2 Backup Solar plus Storage

During a grid outage, the Evolve Hub islands the battery system and

backup electrical panel off the grid. In this mode, the EMC is in a

monitoring state, with most control handed over to the Evolve ESS. The

Evolve ESS curtails V when the battery is either full or exceeds the

charge limit of the battery. On low SOC, the battery system goes into a

standby state until either the solar resource or the grid returns.

IMPORTANT! Shutting off the Evolve Hub circuit breaker at the main

electrical panel will place the ESS into backup mode and continue to

energize the backup panel.

1.5.3 Backup Solar PV curtailment method: requency Shift Power Control ( SPC)

During backup power operation of the Evolve ESS, V curtailment is achieved by shifting the frequency up or down to trip

the V inverter. This curtailment method, defined as frequency shift power control (FS C), is required to prevent solar from

over-charging the battery. By default, the Evolve ESS will ramp up frequency to a V trip range of 62.1 Hz, but this is

adjustable depending on the regulatory frequency trip limits within the jurisdiction.

IMPORTANT! V inverters connected to the backup panel must have frequency trip settings programmed within the

following ranges: V low frequency trip range: 57.0 to 59.3 Hz, V high frequency trip range: 60.5 to 62.0 Hz.

If the V inverter cannot be adjusted within the range specified, the V inverter must not be connected to the backup panel.

Note: The Evolve Hub is not suitable for use in applications where the electric utility prohibits V power export to the grid.

For non-export applications, consult your Eguana dealer for alternate EMS panel solutions.

1.5.4 Circuit and system sizing for 100 / 125 / 150 Amp electrical panels

Line side tapping the main electrical panel is required for ESS installations where the electrical service rating is under 200

Amp. Refer to section 2.3, figure 11.

1.5.5 Circuit and system sizing for 200+ Amp electrical panels

The Evolve Hub may be connected to a 200+ Amp electrical panel using a single 40A breaker. For this configuration, the

total solar V output connected to the backup electrical panel will depend on the curtailment features of the solar V inverter.

If the V inverter is equipped with its own curtailment controls that can limit V output to 5kW or less in backup mode, the

maximum rating of the V inverter connected to the Evolve hub is 7.6 kW AC. For V inverters without internal curtailment

methods, the 5 kW V restriction applies. Regardless of V size, this configuration permits the Evolve Hub’s EMS to limit

continuous combined solar plus storage output to 7.6 kW AC (32 Amp).

1.5.6 Over-sized PV systems

For installations with V systems that are larger

than the Evolve Hub and Evolve ESS can

accommodate, the V inverters must be split up

such that the balance of V is wired directly to the

main electrical panel.

An additional CT must be added to the main

panel connected V inverter.

2.3 SLD - AC Coupled V System with Back-up ower Operation

The single line diagram shown below is a representation of a typical installation configured for utility interactive and back-

up power operation, with AC coupled V connected to a backup panel. This drawing is a guideline only and is not a

substitute for a code compliant installation. All components required for a code compliant installation are the responsibility

of the licensed installer, including any additional circuit protection requirements not shown here.

NOTES

1 - The backup power bus must be electrically isolated from the main electrical bus. Do not tap

the neutral wires of the main and backup buses. Refer to the installation manual for wiring details.

Load circuits are shown for demonstration. Maximum number of circuits determined by sub-panel

rating. Loads connected to circuits must not exceed nominal power ratings (continuous/surge) of

the inverter.

2 – The battery system must be earth bonded to the building ground to meet lightning protection

requirements.

3 – The battery system load and grid ports are independently controlled circuits. Should the

electrical code require additional “line-of-sight” or dedicated disconnects, a separate disconnect

must be used for each of the grid and load ports. The disconnects and/or circuit breakers must

operate independently of each other, and rated for the branch circuit.

4 - CTs are equipped with 8 ft pigtails. Twisted pair extensions can be run up to 30 ft. CT

extensions should not be required if Evolve Hub is within 4 ft of Evolve system.

5 – Ethernet connection between router and EMC is optional. EMC can communicate using Wi-fi

or cellular.

6 – V cannot exceed 5kW AC output in backup mode. V systems larger than 5kW AC must

have a self-curtailment mechanism (software or hardware) to ensure limit is within the 5kW AC

rating. If curtailment means are not available, the balance of V (if applicable) must be routed

directly to the main panel.

7. For electrical services rated less than 200A, the ESS system must be line side tapped as

shown in figure 11.

Disclaimer:

Manufacturer supplied components represented here are limited to the CS/Battery, Evolve Hub, and CTs for V, battery, and mains. All

electrical panel to the backup panel will result in permanent damage to the product.

4.3.1 Phase Orientation in Split Phase 120/240 Systems

The EMC derives power measurement at the main service, the solar

V inverter AC output, and the ESS. Consistent phase voltage

orientation through the entire installation is critical to proper control

of the system. The initial selection of the phase voltage defined as L1

is established by the placement of the CT referenced as CT1 on the

main feeder to the panel. To ensure the phase wiring to the Evolve

hub maintains consistent polarity, measure the AC voltage between

L1 of the main feeder and the Grid terminals of the Evolve Hub. The

pole that measures 0.0 VAC is defined herein as L1 for the AC wiring

instructions that follow.

Appendix B: Multi-mode transfer / bypass relay operation

The Evolve Hub and Evolve CS within the Evolve line of energy storage systems provides fully automated multi-mode

operation, including utility interactive and backup (off-grid) operating modes. The diagram below highlights the three main

relay controls used to transfer the backup panel supply source and island the Evolve CS to a micro-grid during a grid

outage. The battery portion of the Evolve ESS / LF is not shown.

Note: while the EMS is responsible for monitoring CS states and controlling the battery discharge / charge rates, the CS

is responsible for the relay controls, and thus does not rely on EMS communication for transfer of the backup panel source.

igure 25: Evolve Hub and Evolve PCS relay protection definitions in an AC coupled solar plus storage installations.

There are three main protection relays within the complete system, defined below, all of which have internal fail-safe fault

verification circuitry to prevent an unsynchronized CS load to grid output connection.

Kx: Evolve Hub bypass / transfer relay

The Evolve Hub bypass / transfer relay ensures the backup panel is connected to the main panel with or without an

operating Evolve ESS / LF system. When standalone, the Kx relay bypasses the energy storage system to power the

backup panel from the main supply. It remains in the NC or bypass state until powered up with the Evolve ESS / LF

initialized and ready for control. Once the energy storage system’s CS is in a “ready” mode, the CS will take over control

of the backup supply source by transferring Kx to NO, and closing K3 for an uninterrupted transfer. Kx will revert to an NC

state with or without a valid grid if the CS reports a critical service state which prevents it from safely operating the K3

transfer relay.

Fail-safe: Critical failure of the Kx relay will prevent CS operation and will result in loss of power to the backup panel.

K3: PCS transfer relay

This relay operates with Kx as defined above when the Evolve ESS / LF is in a “ready” state. See the table below for a

complete list of CS states. This relay opens upon a grid outage to island the backup panel from the main panel. This relay

acts as the CS grid timing / synchronization grid connect relay when the grid supply returns from an outage, allowing

seamless connection of the battery system and the backup panel circuits to the grid.

Fail-safe: Critical failure of the K3 relay will prevent operation of the CS, but will allow the backup panel to be supplied by

the main panel via the Evolve Hub.

K1: PCS islanding relay

This relay operates as the IEEE1547 islanding relay for grid interactive disturbances (self-clearing), as well as internal and/or

system faults (critical, service mode: non-clearing).

Fail-safe: Critical failure of the K1 relay will prevent operation of the CS, but will allow the backup panel to be supplied by

the main panel via the Evolve Hub.

PCS and Hub relay state map

The following table summarizes the CS operating states in both utility interactive and offgrid operating modes. The

corresponding relay states and backup panel supply source are also identified. The “ CS ready” column indicates the CS

states of operation where the CS has control over the relays.

Backup supply interruption period during grid outage / return to grid

A grid outage results in a four second power interruption to the backup panel. On return of the grid supply, the energy

storage system and V inverters sync and grid connect without interruption to the backup panel.
