EG4® 12kPV HYBRID INVERTER The EG4 12kPV is a 48V split-phase, hybrid inverter/charger capable of utilizing 12kW of PV input and efficiently outputting 8kW of power while also charging your battery bank. Parallel up to 10 units for 80kW of output power and control multiple stations and units using the new EG4 monitoring software.

HIGH REMOTE FREQUENCY 10-YEAR ADJUSTMENT SPLIT-PHASE WARRANTY VIA EG4 DESIGN SOFTWARE

ALL-IN-ONE HYBRID INVERTER Capable of running entirely off the grid, using grid electricity, or selling power back to the grid.

UP TO 600VDC INPUT The extra high voltage enables lower cable sizing for the 2 MPPTs and a maximum recommended PV input of 15kW, eliminating the need for a combiner box.

PLUG IN WI-FI DEVICE Enables wireless connection between our new monitoring platform and the 12kPV through the EG4 app or EG4 Monitor system.

CLOSED-LOOP COMMUNICATIONS Able to communicate with EG4 48V batteries and other battery brands. A battery firmware update is required for closed-loop communications with LifePower4 batteries.

RAPID SHUT DOWN The 12kPV is CSA C22.2#330:2017 and NEC 690.12 ready with its built-in RSD capabilities.

DUAL ON-BOARD FIRE ARRESTORS -safe protection against thermal runaway.

WEATHER-TIGHT QUICK CONNECTS Included battery cables with outdoor rated connectors allowing for fast, safe, and reliable battery connections.

INTEGRATED SELF-HEATING FEATURE Heats the battery when the ambient temperature is low. A key feature for outdoor Lithium battery cell operations.

INTEGRATED BUSBARS The battery design comes manufactured with 600A internal busbars with multiple terminals (4 positive & 4 negative) eliminating the need for external busbars when paralleling batteries and/or multiple inverters.

INNOVATIVE EMERGENCY STOP FUNCTION The optional ESS disconnect can shut down all batteries and inverters (if equipped with rapid shut down capability) with the press of a button.

THE PERFECT PARTNER TO THE EG4 18kPV The optional conduit box mates up directly to the connection ports of the inverter allowing a sleek installation. For other inverters or stand-alone battery installation, the conduit box plugs should be installed. *For information regarding warranty registration on EG4® Electronics ©2025, EG4® ELECTRONICS, LLC.

RE: Structural Certification for Installation of Residential Solar JENNIFER AKERBERG:3985 N BEAR CREEK LANE, CASA GRANDE, AZ 85122

Attn: To Whom It May Concern

This Letter is for the existing roof framing which supports the new PV modules as well as the attachment of the PV system to existing roof framing. From the field observation report, the roof is made of Composition shingle roofing over roof plywood supported by 2X6 Rafters at 24 inches. The slope of the roof was approximated to be degrees.

After review of the field observation data and based on our structural capacity check, Existing roof framing have been determined to be adequate to support the imposed loads without structural upgrades. Capacity calculations were done in accordance with applicable building codes.

We have based our structural capacity determination on information in pictures and a drawing set titled PV plans - JENNIFER AKERBERG. The analysis was according to applicable building codes, professional engineering and design experience, opinions and judgments. The calculations produced for this dwelling's assessment are only for the proposed solar panel installation referenced in the stamped plan set and were made according to generally recognized structural analysis standards and procedures.
