The Encharge" storage system includes the Enphase Encharge Battery(ies) with integrated Enphase IQ" Microinverters. The Enphase IQ Envoy" commu- nication 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 loadpanel. This configuration supports up to an BOA breaker forthe PV circuit and an 80A breaker for battery storage. Whole home backup with Enpower as service entrance and PV combiner connectedto main loadpanel. 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 BOA. 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 BOA, this is the preferred configuration for partial home backup with subpanet.

The terminal blocks accepts copper conductors of No. 12 - 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 o to 100 o RH, non -condensing, preferably out of direct sunlight. The optimum ambient temperature range for installation location is 0° C to 30° C (32° F to 86° 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 Ibs). Total weight for the Encharge 10, including the three Encharge base units, cover, and wall mount bracket, is 154.7 kg (341 Ibs). 0 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. AS 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 one 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 AC discon- nects 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 drawing only shows switches). 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. If there are only three Encharge 1 Os, for example, then you can use a box with current rating less than 80A. To do this, you must purchase an off -the -shelf subpanel and install as shown in the following image: Enpower Off the shelf combiner box. ® Install the AC disconnect Following 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 installed in 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. ® Prepare to install the wall -mount bracket A) 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 sustain the weight of the Encharge batteries and mounting bracket.
