AC Balance of Plant (BOP) Power Distribution Systems

APT's Advanced Power System (APS) will have you covered from primary utility intertie to backup generator paralleling, to unit substations all the way down to point of use panelboards. No matter how complex the project, trust APT to develop a solution that suits your needs and your budget!

Utility Switchgear

APT's “-UI” Utility Switchgear offers an innovative, compact, and cost-effective means to be used as interconnection switchgear to connect loads to the utility transmission system at the 2.4kV through 38kV voltage classes. With customizable features from instrumentation transformers to satisfying specific utility intertie switchgear requirements, APT’s line of “-UI” utility switchgear is the perfect powerful interconnection switchgear solution.


Photovoltaic (PV) Solar Power AC Collection, Distribution, Grid-Tie Switchgear System

Let APT be your source for alternative renewable energy Balance of System (BOS) equipment for Solar Farm Power Systems & Photovoltaic (PV) Power Plants. APT has the resources and expertise to provide safe, reliable, and cost-effective solutions for the collection of solar generated power for utility scale grid tie and microgrid applications. No matter how large or small, simple or complex the site is, APT has you covered from the inverters to Point of Common Coupling (PCC).

Microgrid Sustainable Energy Systems

APT can do it all! APTGrid provides real time integrated management & control of power production and power consumption for large scale (500kW – 50 MW) microgrids. This involves the aggregation of several APT switchgear and control systems for various distributed energy resources (DER). Working in both grid-connected and grid-isolated modes of operation, instantaneous, load matching, and active control of microgrid stability, our engineered microgrid solutions are a perfect fit for any utility, community power, and large scale application.

Combined Heat & Power (CHP),
Co-generation Switchgear,
Air Handling & Control Systems

APT's CHPSA Combined Heat and Power System (CHP, Co-generation) increases Energy Efficiency and Reliability to allow our customers to generate heat and power on-site. Addition of heat recovery, increases typical electrical output efficiencies in the range of 30% to 42% to the overall CHP system efficiency of up to 83%!


Power Converter & Conditioner Motor-Generator System

APT RotoVerter Power Converter & Conditioner Motor-Generator System is a true rotating energy conversion generator to support the generation of AC from DC renewable generated power and support a commercial load's high inrush currents. It is ideal for use in Microgrid, rotary UPS, solving power quality problems, frequency converters, and voltage converters.


Battery Energy Storage System

APT EnerStore Battery Energy Storage System (BESS) provides state-of-the-art grid/microgrid stabilization for renewable generated power, including solar, wind, etc. APT BESS can be stand alone NEMA 1, outdoor NEMA 3R, or fully integrated with low voltage switchboards, transformers, and medium voltage switchgear all in a single Outdoor Walk-In ISO Container Based Solar Power Combination Module. Stabilize your renewable power system with an EnerStore Battery Energy Storage System (BESS).
