Determine Primary Side of Transformer in Solar PV Applications
In the PV/Solar grid-tie applications the primary side of transformer is often incorrectly identified as the side connected to the solar inverter. In practice; the transformer will initially be energized from the side tied to the facility/utility grid.

Poor Connectivity - A Costly Threat to Your Solar PV System
Solar PV systems consist of many components, which are connected by cables and connectors. This is one of the main safety hazards of any solar PV system. In this Solis article we'll share how a connectivity failure could create a security problem and how to prevent it.
All-in-One Energy Storage System
When solar or shore power is available, the solar inverter charger can use the solar or shore power to charge the lithium iron phosphate batteries and keep the batteries topped off.
Understanding the Chemistries of Deep-Cycle Batteries
Advancements in battery chemistry and design have allowed deep-cycle batteries to deliver longer cycle life and higher capacity and cycle-up to full rated capacity faster than previous designs.
Lead Batteries Will Help Power the Future
Compared to newer battery technologies, lead batteries are inexpensive to manufacture. According to the Department of Energy, lead batteries have a lower capital cost of $260 per kilowatt hour (kWh) compared to lithium at $271 per kWh.
With The Right Storage Solution, Energy Freedom Begins at Home
Franklin Whole Home has entered the residential energy-storage market with an eye to moving homeowners beyond energy security toward true energy freedom.
The Coming Home Energy Management (R)Evolution
Electrical hardware and software developments are pulling the residential energy storage system (ESS) market forward by enabling intelligent home energy management solutions that solve important problems for installers and customers alike.
Innovations in End of Life Lithium-Ion Battery Disposal & Recycling
To make a lithium-ion battery, the components have to be mined and refined. Cathodes are built, and the batteries are manufactured. When those batteries no longer hold a charge, they have to be recycled to reclaim as many metals and plastics as possible.
Energy Storage System Companies Are Racing to Scale Production
Success requires overcoming a myriad of challenges including a shift in preferred battery chemistries, the industry's transition to long-duration storage, time-to-market and cost pressures as well as navigating global supply chain constraints.

HPS EnduraCoilTM Cast Resin Medium Voltage Transformer
HPS EnduraCoil is a high-performance cast resin transformer designed for many demanding and diverse applications while minimizing both installation and maintenance costs. Coils are formed with mineral-filled epoxy, reinforced with fiberglass and cast to provide complete void-free resin impregnation throughout the entire insulation system. HPS EnduraCoil complies with the new NRCan 2019 and DOE 2016 efficiency regulations and is approved by both UL and CSA standards. It is also seismic qualified per IBC 2012/ASCE 7-10/CBC 2013. Cast resin transformers are self-extinguishing in the unlikely event of fire, environmentally friendly and offer greater resistance to short circuits. HPS also offers wide range of accessories for transformer protection and monitoring requirements.
