Enphase ENCHARGE-3-1P-NA All in One Energy Storage System Installation Guide

QUICK INSTALL GUIDE(Models ENCHARGE-3-1P-NA and ENCHARGE-10-1P-NA)Install the Enphase Encharge Storage System

To install the Enphase Encharge 3TM storage system or Encharge 10™ storage system and the Enphase wall-mount bracket, read and follow all warnings and instructions in this guide. Safety warnings are listed on the back of this guide. These instructions are not meant to be a complete explanation of how to design and install an energy storage system. All installations must comply with national and local electrical codes and standards. Only qualified electricians shall install, troubleshoot, or replace the Encharge 3 or Encharge 10.

The EnchargeTM storage system includes the Enphase Encharge Battery(ies) with integrated Enphase IQTM Microinverters. The Enphase IQ EnvoyTM communication gateway measures PV production and home energy consumption. The Encharge storage system senses when it is optimal to charge or discharge the battery so that energy is stored when it is abundant and used when scarce. Encharge storage systems are capable of providing backup power when an Enphase Enpower™ smart switch is installed at the site.Five unique installation scenarios are shown:

Whole home backup with Enpower as service entrance and PV combiner connected to Enpower. This is the preferred configuration for back up of the entire main load panel. This configuration supports up to an 80A breaker for the PV circuit and an 80A breaker for battery storage.NOTE:

  1. For M215/M250 connection to Ensemble, refer tech brief at https://enphase.com/en-us/storage-m-series
  2. M series microinverters require Envoy-S metered.

Whole home backup with Enpower as service entrance and PV combiner connected to main load panel. This is the preferred configuration when you back up the entire main load panel, and the size of the PV combiner circuit is more than 80A. In this configuration, the PV combiner circuit connection space in Enpower is left vacant. When existing PV combiner circuits are connected to the main load panel, and you want to add battery storage to the system, you can keep the PV combiner connected to the main load panel and connect only the battery storage system to Enpower.

Partial home backup with main load panel as service entrance and PV combiner connected to Enpower. When PV circuits breaker size is less than 80A, this is the preferred configuration for partial home backup with subpanel.

  • The Encharge 3 includes one battery, and single-width cover with mounting bracket.NOTE: Check the “Energize By” label on the shipping box to verify that the Encharge Battery(ies) will be installed by the date shown. If the date has passed, contact your distributor for next steps.WARNING: Risk of injury. Take care when lifting. The Encharge Battery unit is heavy (44.2 kg/ 97.4 lbs) and requires two persons to lift.

C ) Ensure you have the following required Enphase items for backup systems:

  • An Enphase Enpower smart switch with microgrid interconnect device (MID) functionality and an Enphase IQTM Combiner.
  • The Enphase Encharge system requires an Internet connection through the IQ Envoy in the IQ Combiner. Failure to maintain an Internet connection may have an impact on the warranty. See enphase.com/warranty for full terms.
  • Wireless communications kit (COMMS-KIT-01) to be installed at the IQ Envoy for communications with Encharge and Enpower. Includes USB cable for connection to IQ Envoy / IQ Combiner and allows wireless communication with Encharge and Enpower.
  • Encharge lifting handles two pieces (ENCHARGE-HNDL-R1).

D ) Make sure you also have the following required items:

  • Mounting location that is structurally suited to bearing the weight of the Encharge Battery(ies). Total weight for the Encharge 3, including the Encharge base unit, cover and wall mount bracket, is 52 kg (114.6 lbs). Total weight for the Encharge 10, including the three Encharge base units, cover, and wall mount bracket, is 154.7 kg (341 lbs). The wall must contain blocked studs that can bear the battery weight or can be of masonry or other suitable structure.
  • Tools: conduit (with fittings and fitting tools), drill, 5/32 inch pilot bit (or metric equivalent), screwdriver, socket wrench, torque wrench, level, wire stripper, and stud finder if installing on studs.
  • Fasteners for wall mount bracket. Slots are 6.8mm (0.27″). Check with a structural engineer and local standards for requirements: Single-wide bracket: Three 1/4″ lag bolts or screws, 7.6 cm (3 inches) long (depending on attachment wall). Triple-wide bracket: Nine 1/4″ lag bolts or screws, 7.6 cm (3 inches) long (depending on attachment wall).
  • Washers for use between fastener heads and wall-mount bracket.
  • Copper conductors: No. 14 – 8 AWG (11mm/7/16 inch strip length) copper conductors (rated at 75° C or 90° C) for terminals.
  • Conduit fittings: 3/4 inch (left side) and 1/2 inch (right side) hubs are required for all installations, and NEMA Type 3R conduit fittings (hubs) are needed when installing out of doors (one for each used conduit opening). Also needed are conduit plugs to close unused conduit openings and conduit grounding nuts.
  • Over current protection: The overcurrent protection in Encharge is not branch circuit overcurrent protection and cannot be relied upon for that purpose. The branch circuit overcurrent protection is located in Enpower or, when combining , in a separate combiner. See the Enphase Enpower Quick Install Guide for more information.
  • Personal protective equipment (PPE) for handling lithium batteries as required by local safety standards.

E ) Verify that main service is 120/240 VAC, and not 208/120 VAC. Encharge batteries cannot be installed where L1 to L2 measures 208 VAC.F ) Install the PV system and the IQ Combiner as directed by the Enphase installation manuals.

INSTALLATION

  1. Plan a location for the Encharge batteriesThe Encharge housing is NEMA type 3R and can be installed indoors or outdoors. The terminal blocks accepts copper conductors of No. 14 – 8 AWG.A ) Following local standards, choose a well-ventilated location where the ambient temperature and humidity are within -15° C to 55° C (5° F to 131° F) and 5% to 100% RH, non-condensing, preferably out of direct sunlight. The optimum ambient temperature range for installation location is 0º C to 30º C (32º F to 86º F).B ) Ensure that the mounting location can sustain the total weight of the Encharge batteries and mounting bracket. Total weight for the Encharge 3, including the Encharge base unit, cover and wall mount bracket, is 52 kg (114.6 lbs). Total weight for the Encharge 10, including the three Encharge base units, cover, and wall mount bracket, is 154.7 kg (341 lbs). WARNING: The installer should install blocking between studs to ensure that no single stud carries the entire weight load of the Encharge batteries.C ) Plan the mounting location to be at least 15cm (six inches) off the ground and 15cm (six inches) from the ceiling. Keep the Encharge away from falling or moving objects, including motor vehicles. WARNING: If mounted in the path of a motor vehicle, we recommend a mounting height that is 91 cm (36-inch) minimum above the floor.D ) Ensure that there are no pipes or electrical wires where you plan to drill.E ) Plan to maintain at least three feet of clearance in front of each Encharge. Allow at least 15cm (six inches) clearance on top and bottom of the Encharge so that the vents on the top and bottom of the units are not blocked for air circulation.F ) Consider the dimensions of the Encharge batteries, easy access, height, and length of cable when selecting the location.G ) Select a location where you can interconnect to the Enphase Enpower smart switch.H ) Follow all local standards.J ) Review your external conduit plan to determine to which side of the field wiring compartment you will connect conduit.K ) Up to two Encharge 10 (or six Encharge 3) units can be daisy chained on a single branch circuit. For installations with more than this number of units, there must be a separate load center, subpanel, or circuit combiner with over current protection to combine the daisy chained circuits, and you must run only one circuit for all the Encharge units to the Enpower (or to Enphase IQ Combiner for grid-tied-only installations). You must select proper conductors and circuit breakers for these circuits according to local codes, standards, and other applicable requirements. Enpower supports up to a maximum of 80 A breaker for Encharge connection circuit.The subpanel could be a small, two circuit box with circuit breakers. The circuit breakers in the box would have to be suitable for back-feeding, per NEC 408.36(D).Select the right size subpanel and breakers based on the number of Encharge units being installed. Up to four Encharge 10s or twelve Encharge 3s can be safely connected to 80A load center.To do this, you must purchase an off-the-shelf subpanel and install as shown in the following image:
  2. Install the AC disconnectFollowing all local codes and standards:A ) Install an AC disconnect that can break the maximum rated current of the branch circuit under load. The AC disconnect must be readily accessible and located within line-of-sight of Encharge, per NEC 2017 706.7(A).B ) Each Encharge unit is suitable for use with up to No. 8 AWG wires on a maximum 40 A branch circuit. If more than 32 A of Encharge batteries (corresponding to a 40 A branch circuit) are installed, a separate subpanel must be installed between the Encharge units and Enpower to combine the Enpower circuits together. All circuit breakers in the subpanel must be suitable for back-feeding, per NEC 408.36(D).C ) Verify that AC voltage at the site is within range: single-phase L1 to L2 voltage must measure between 211 and 264 VAC, while L-N should measure between 106 and 132 VAC.
  3. Prepare to install the wall-mount bracketA ) Make sure that the planned position for the wall-mount bracket meets clearance requirements as shown. The image depicts a single bracket, but clearances and requirements are the same for the triple-width bracket.B) Ensure that the mounting location can sustan the weight of the Encharge batteries and mounting bracket. Total weight for the Encharge 3 including the mounting brackets and cover is 52 kg (114.6 lbs), while the total weight for Encharge 10 including the mounting bracket and cover add up to 154.7 kg (341 lbs).C ) Starting at installation position closest to the power source, mark a level line on the wall as a guide. WARNING! Multiple risks. Make sure not to drill or attach into electric wiring or pipes that are in the wall!Mounting Surface Flatness (Across the Installation width and height) recommended to be within 2mm*NOTE: The above specified surface flatness requirment is applicable to all the combinations of Encharge 3 and 10.* If the difference in flatness is more than 2mm, recommend installing a substructure like unistrut for better alignment of the units.

  6. Install conduit and field wiring DANGER! Risk of electric shock. The DC switch must be in the Locked position before performing this step.A ) If not already done, use a Phillips screw driver to loosen the screws securing the field wiring compartment cover and remove the cover. Keep the cover and screws handy as you will need them later.B ) Remove the sealing plug for entry into the field wiring compartment. If installing only one battery or when installing the last battery in the array, seal up the hole with the supplied sealing plug.C ) Size the conductors (Lines and Ground) to account for voltage rise and to conform to the tables below. Design for a voltage rise total of less than 2%. Encharge can use any circuit breaker size between 10 A and 40 A. Breaker rating and wire size are installation dependent.
    Number of Encharge E3/E1 0 units Current (A) Minimum wire size (AWG) Breaker rating (A)
    1*E3 5. 14 10
    2*E3 11. 14 15
    3*E3 or l*E10 16.0 12 20
    4*E3 or (1*E 1 0 + 1*E3) 21. 10 30
    5*E3 or (1 *E1 0 + 2*E3) 28. 8 35
    6*E3 or 2*E10 or (1*E1 0 + 3*E3) 32.0 8 40

    *E3 refers to Encharge 3*E10 refers to Encharge 10In all cases in the table, it is possible to always use larger conductors and a breaker sized for that conductor or smaller. For Example in row 3, with 3*E3 or 1*E10, it is possible to use:a) 12 AWG wire with 20 A breaker, orb) 10 AWG wire with 20 A or 30 A breaker, orc) 8 AWG wire with 30, 35, or 40 A breaker DANGER! Risk of electric shock. Check that the dedicated circuit breaker protecting the branch where the Encharge Battery(ies) will be connected is turned off before wiring. WARNING! Risk of equipment damage. The DC switch must be OFF before installing, otherwise Encharge will try to form a grid.D ) If installing an Encharge 10, install the inter-unit raceways. The left-side and right-side conduit openings are different diameters, so you must install the raceway in the proper direction.• Face the fronts of the batteries, and insert the raceway through the right-hand unit’s left-side conduit opening from within the field wiring compartment, with the arm of the raceway pointing up.• Push the raceway through the right-hand unit’s left-side conduit opening and into the left-side unit’s right-side conduit, opening until the two snap features on the raceway engage the left-side unit’s enclosure.• Once fully inserted, rotate the “arm” toward you until it stops.• The left-side conduit opening of each battery unit has a flat surface, without additional features. The larger seal (green) on the raceway mates with this opening. The right-side conduit opening has a groove around the hole to fit the O-ring (red) of the raceway. Make sure that the O-ring is captured in the groove between the Encharge enclosure and the raceway flange adjacent to the O-ring.E ) Using the conductors and suitable conduits, connect the AC disconnect and the first adjacent Encharge Battery. Use the conduit openings provided to connect the conduit and pass the wires through them. Note that if an Enphase Enpower is in line-of-sight, the breaker can service as a disconnect. WARNING! Risk of equipment damage. Do not modify or rewire the pre-installed wiring or bonding connections in the field wiring compartment. WARNING! Risk of equipment damage. Always connect to two Lines (active) and one ground.F ) Connect each wire in the field wiring compartment to its corresponding conductor (Lines and Ground). Each terminal accepts two 14-8 AWG conductors (11mm/7/16 inch strip length). Tighten to 14 lb-in.G ) If installing an Encharge 10, route the wires from the first Encharge Battery to the adjacent Encharge Battery through the inter-unit raceway. There are two positions for each line and for ground in the terminal block to allow for daisy-chaining. WARNING! Risk of equipment damage. Do not daisy chain more than six total Encharge 3 or two Encharge 10 on a single branch circuit.H ) After all wires in the field wiring compartment are connected and secured, check that there are no exposed conductors.I ) If connecting additional Encharge Batteries, use another conduit and another set of wires to connect between field wiring compartments.J ) Gently arrange all the wires and connectors inside the field wiring compartment.K ) Plug any unused conduit openings before proceeding.L ) Replace the field wiring compartment cover. Use a cross-head screw driver to tighten the cover screws to 2.3Nn (20.3 Ib-in). WARNING! Risk of equipment damage. Ensure that no wires are pinched before replacing the cover. DANGER!
