The Electrical Equipment That Makes Your DER System Work

AMRENERGY engineers, supplies, and installs the complete electrical infrastructure for C&I DER systems — switchgear, inverters, transformers, automatic transfer switches, metering, and all balance-of-system components — specified, coordinated, and monitored as a unified system.

Why Electrical Equipment Matters

Every DER System Is Only as Reliable as Its Electrical Infrastructure

Solar panels, batteries, fuel cells, and generators generate and store power. But none of it reaches your facility safely or efficiently without the right electrical equipment — switchgear that protects the system, inverters that convert DC to grid-compatible AC, transformers that step voltage for distribution, transfer switches that manage source transitions, and metering that feeds the data for intelligent optimization.

AMRENERGY specifies, sources, and installs all electrical balance-of-system (BoS) equipment as an integrated part of your DER system design. Every component is selected for compatibility with your generation assets, your facility’s existing infrastructure, your local utility interconnection requirements, and our DERMS monitoring platform.

The result is an electrical system that is code-compliant, utility-approved, and fully monitored from day one — with a single point of accountability from the inverter to the switchboard.

Equipment Categories

Complete Electrical Infrastructure for C&I DER Systems

Solar & Storage Inverters

String, central, and three-phase inverters convert DC power from solar arrays and battery systems to grid-compatible AC. AMRENERGY specifies inverters with the right efficiency curve, grid-forming capability, and reactive power control for your installation.
String Inverters Central Inverters Hybrid Inverters Grid-Forming IEEE 1547

Automatic Transfer Switches (ATS)

ATS units monitor grid voltage and frequency, automatically switching your facility to on-site generation within milliseconds of a grid anomaly. AMRENERGY integrates open-transition and closed-transition ATS for different load criticality levels.
Open Transition Closed Transition Bypass-Isolation UL 1008 NEMA 3R / 4

Switchgear & Switchboards

Commercial and medium-voltage switchgear protects your DER system and facility electrical infrastructure. AMRENERGY selects and installs low-voltage and medium-voltage assemblies rated for your system's fault current levels and operational requirements..
LV Switchgear MV Switchgear 480V–35kV UL 891 ANSI C37

Distribution Transformers

Step-up and step-down transformers match generation and storage output voltages to your facility's distribution voltage and utility interconnection requirements. AMRENERGY engineers transformer sizing and impedance for DER grid interconnection compliance..
Pad-Mount Dry-Type Step-Up / Down IEEE C57 DOE 2016

Revenue-Grade Metering & Sub-Metering

Accurate revenue-grade metering captures solar generation, battery throughput, generator output, and facility consumption for utility compliance, incentive verification, and DERMS optimization. Sub-metering enables per-tenant billing allocation.

Protection Relays & Overcurrent Devices

Protective relaying coordinates fault isolation across your DER system — preventing cascading failures and ensuring IEEE 1547 anti-islanding compliance. AMRENERGY conducts protection coordination studies to confirm correct relay settings for your interconnection.
