OVERVIEW:

The EQB is a plug in 200A Grid Isolation Meter Socket Adapter for use with Energy Storage Systems (FranklinWH aPower 2/S & MAC), featuring optional built in 100A DER Tap & sensors for PCS control of import/export. EQB simplifies traditional ESS installation practices by effectively replacing the MID in a traditional system architecture, allowing for Solar, Battery, & EV’s to either interact with the Grid for DER programs, or isolate from the Grid for backup power purposes. EQB enables plug & play electric panel upgrades by integrating with backup battery inverters to control a facility’s connection to the electrical grid automatically or on demand, while also utilizing CT’s for inverter PCS control. Whole Home Backup can be achieved by installing the EQB behind the utility meter (Utility Approval Required), & Partial Home Backup can also be achieved by installing a meter socket downstream of customer load panel & relocating ESS & desired backup loads to a subpanel located after the EQB meter socket (C10 can install using this method).

The EQB has two modes of operation:

1. Interactive Mode (Grid Following Inverters)
   • EQB's Grid Isolation Relay remains in Closed position, enabling DER system to interact with the Grid as a Generation Source for NEM, VPP, & other DERMS.
   • Can stay on Grid permanently until a compatible system is connected to EQB.
2. Grid Isolated Mode(Hybrid Grid Following/Forming Inverters)
   • EQB's Grid Isolation Relay can be switched to Open position by Inverter control, automatically or on demand, enabling DER ESS system to power a home without backfeeding the grid.
   • Visual Indicator Manual Bypass available to reconnect to Grid if Inverter fails.

The EQB enables two types of interconnection methods:

1. Load Side Tap - Isolation only
   • DER(s) interconnected in Load panel, electrically after Main Breaker
   • DER Breaker space available in Main Service Panel or Subpanel
   • Panel Expansion PCS control of Busbar from FranklinWH CT's in EQB

2. Line Side Tap: Isolation + Panel Expansion (DER TAP)
   • DER(s) connected via EQB’s built in 100A DER Lugs (located electrically after isolation switch, before Main Breaker).
   • Two methods of Panel Expansion, DER Lugs & Panel Expansion PCS control of Busbar from FranklinWH CT’s in EQB.
   • Most effective when breaker space or other constraints would normally
   require the installation of a subpanel or Main Panel Upgrade.
   • DER’s can be split between Load & Line Panels for easy AC Coupling.
   • Neutral Pigtail must be bonded to Neutral bar in Panel or Utility Neutral wire in Utility Pull Section or Meter Socket.
   • AC Disconnect must be grounded per local AHJ requirements. (UFER/Rod)

WHAT YOU WILL NEED:

LICENSED ELECTRICAL CONTRACTOR, AHJ & UTILITY APPROVAL FOR ESS COMPONENTS.

UTILITY METER TECHNICIAN REQUIRED TO INSTALL WITH UTILTIY METER.

+ WHEN USING OPTIONAL 100A DER TAP CONNECTION:

• AC Disconnect (Fused Lockable Blade or Breaker in Subpanel, per local AHJ/NEC)
• (1) 1.25” (1 ¼”) Liquid Tight Non-Metallic Flexible Conduit (NMFC-B)
• (2) 1.25” (1 ¼”) 90* Conduit Straight/Elbow Connector(s)
• (3) #3 AWG THHN/THWN (L1, N, L2 for 100A DER Tap, #6 AWG ok for 1 battery, follow local AHJ & NEC guidance)
• 1” or larger EMT Conduit / Liquid Tight NMFC from disconnect to FWH BESS
• Neutral Bonding via Polaris connector (PGE, SDGE, SCE), Single Use Insulation Piercing Connecter (ie: ILSCO KUP-L-Tap Insul-Eater), #4AWG Neutral Lug in Load side of panel (PGE), Neutral Lug kit from panel manufacturer (PGE, SCE, SDGE), or similar UL Listed / AHJ approved neutral bonding method (Please list method on plans submitted to Utility/AHJ).
• External Grounding REQUIRED from AC disconnect to UFER/Ground Rod/Etc, per local AHJ requirements, unless installing in SDGE. It is recommended to utilize external grounding. Please list chosen external grounding method on plans submitted to Utility/AHJ.

If installing in PGE & SCE territories, please remove Green wire from EQB's lugged connection in Upper Junction Box, as they will NOT install if present.

EQB MIM 200 Plus PE compatible panel examples:

Some panels with breakers above meter socket require alternate EQB model with junction box on left/right for clearance purposes, please contact your distributor for more information.

EQB INSTALLATION

• Ring style 2S meter socket. (Ringless option available)
• No clearance issues, breakers are accessible. If panel door access is an issue, one of the vents can be swapped for waterproof knockout, or use EQB with left/right junction box.
• Minimum 10” working clearance for meter technicians.
• No Electrical Service Violations, site meets NEC, Utility & AHJ code requirements.
• NMFC from EQB secured within 12” of meter socket & strapped every 12” or less.

• AC disconnect must be landed within 6.5’ radius of meter socket (no gas meter <36”)< /li>
• AC Disconnect must be Grounded & bonded per local AHJ requirements. External grounding to UFER or ground rod is recommended. (Only SDGE permits adapter grounding)
• AC Disconnect & all conductors match system amperage on stamped plans.
• NMFC from EQB secured within <12” & strapped every <12” to MAC / AC Disconnect
• Neutral connection must be bonded to panel or utility Neutral feeder line.
• PGE requires installer placed landing lug on existing neutral bus to bond neutral, with a port from meter socket to load center, some panels have this feature while others need installer to create a path through the insulating material for PGE meter techs. SCE may ask installer to utilize this method for meter sockets above load center due to limited space.

• Some Utilities (PGE, SCE, SDGE) do not allow new devices within a 36” radius from the bottom of the Gas Meter regulator. If your meter socket falls within that radius, your local AHJ & Utility will ultimately determine if EQB can be installed.
• If gas meter is within 36” of meter socket, AC Disconnect must be placed outside of 36” and within 6.5’ radius of meter socket, with 12” minimum lateral clearance required on either side of gas lines, & restrictions extending up to 10' high for surrounding environment.

• Note: Steps 3-7 ONLY to be performed by qualified personnel wearing Proper Arc Flash PPE for working with live unregulated 240v. NO METAL JEWLERY OR CLOTHING ALLOWED.
• PGE, SCE, & SDG&E REQUIRE THEIR APPROVED METER TECHNICIANS TO INSTALL.
• RISK OF DEATH WHEN PERFORMING THESE TASKS!
• Leave Behind Condition Required for all installs, with EQB in orange bag for meter tech install.

• Turn off Main Breaker to disconnect utility power from the facility load panel.
• Turn off any Breakers and AC Disconnects to backup power (if present) confirm no secondary voltages present using voltmeter in load center.
• Remove Lockring.
• Put on insulated gloves with arc flash protective PPE & Flame-Resistant clothing.
• Pull down on smart meter with two hands to safely remove the meter. A Meter Puller can also be used if available.
• DO NOT TOUCH ANY METAL INSIDE PANEL, ASSUME ALL CONTACTS ARE ENERGIZED.
• Verify voltages & grounding in panel.
• Verify neutral bonding location & method.
• Confirm jaws in meter socket are within specifications using a Hot Socket Gap Indicator.

• When utilizing DER Tap, feed Neutral wire (& Ground in SDGE) through meter socket to utility pull section (PGE requests feeding Neutral through to forked lug attached to Neutral bus in customer side of load panel).
• Align EQB stabs with Meter Socket Jaws.
• Press firmly into place.
• Confirm continuity between L1/L2 of Utility Feed Line landing lug and meter socket jaws.
• Place lockring to secure adapter to panel (Screw Type Lockring preferred to support weight).

• Verify conduit lengths & fitment to prevent tension on meter socket, trim to fit as needed.
• Feed all wires through conduit into adapter. Use caution as some connectors can be very sensitive, taping wires with electrical tape and fiberglass fish tape is preferred. When using 90* conduit elbows, disassembling connectors and conduit can help feed wires easier.

• Close Main Breaker to restore power to home.
• Read meter, confirm screen is active, and load is being delivered. If no power, open EQB junction box, locate connections inside the lid, initiate Manual Bypass operation to close back to grid (Step 7).

• WARNING – ASSUME ALL CONTACTS ARE ENERGIZED WITH 240V AC POWER.
• Carefully open EQB upper junction box, locate connections inside the lid.
• Find 6 pin connector coming from EQB lid (middle size of the 3 connectors, rectangle).
• Connect 6 pin connector to mating 6 pin connector (J1) in lid of EQB.
• Confirm EQB status in visual indicator STATUS window (LINE, OPEN, CLOSED).
• Grid status (LINE) should always be illuminated, EQB switch position Visual Indicator (OPEN, CLOSED) only available when 6 pin connector is plugged into mating connector (J1).
• Press button (PB1) to close EQB on to the grid. Audible “CLICK” sound from EQB.
• Confirm EQB status in visual indicator STATUS window (LINE, OPEN, CLOSED).
• If ESS commissioning has been completed, it is ok to reconnect to wiring harness.
• Confirm smart meter is reporting power to home & main breaker is closed on grid.
• Close junction box.
